At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goals reality is our passion. Richard W brought his 1971 Datsun 240Z from Eureka, Ca for a full mechanical restoration, ZCG-style. Our Z Car Garage Big-BrakesZ Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain and full suspension transformed this Series 1 S30.

 
 

In 2017 Richard contacted us to inquire about restoration work. He understood we were booked, and we spoke again later, but this time he visited the shop with a photo album filled with photos of his beautiful, Sunshine Yellow Z.

“I did my due diligence and researched what ZCG could do, and arranged for a meeting with Rob to discuss my car. I asked if he would be interested in restoring my 1970 240 Z.  He was pretty adamant, ‘I don’t restore those rust buckets anymore.’ A little disheartened but I persisted. Would you take a look at the album I have of my car? He flipped through he pages and you could see him light up and the enthusiasm came forth. He said, ‘Where is the rust?’. I told him there was none as the car has been indoors for the last 40 years.”

 

Rob and Richard agreed that since the exterior was in great shape ZCG would perform a mechanical restoration. Richard is in his 70’s and still practices dentistry in the small town of Eureka. After being parked for decades he trailered the Z down and arrived at ZCG in January 2018 . Here is VIN #12291, with 63k original miles:

 

He bought this Z brand new 12/70 and absolutely adores it, being an integral part of his life for half a century! We love the story behind Richard’s Z lets’ take a look before going into the mechanical work…

Life With The Z

 

“We all have defining moments in our lives and those moments need to be prioritized. The marriage to my wife of 50+ years is of course the most important moment. She provided the resources to live in San Francisco and was so supportive of my graduation from college. That same year she became pregnant with our first born. We moved to Eureka at the same time. I was able to start my own business in 1970 and begin an adult life. All the important hurdles were checked off. We moved to Eureka with $300 in our pocket and a mountain of debt. But wait, there was one more hurdle…”

 

“…From across a parking lot, in Eureka no less, stood a bright yellow Ferrari. Upon closer inspection I was even more baffled. What was a Datsun 240Z?  I went to the local Datsun agency, long before Nissan came along and made my inquiry. Yes, the new 240Zs are very special and very desirable. They were being shipped in but there is a waiting list. Just add my name.  Sure enough they called a few weeks later and said there was an Orange Z on the lot. They made the mistake of letting me wring that car out and I was sold. While I was in school in San Francisco, I saw Cobras and Porsches that cost $6 – $7,000. Way out of my league but I could afford the $3,600 Z. Even if it meant borrowing $1,200. In early December 1970 I took possession of my Z. It became my car and my identity. It has remained just that for the last 50 years.

 

“My oldest son was born the following February. Now all the pieces for my life fell into place. Marriage, college, moving to a permanent home, birth of our son and the final piece, my sports car. Being a young family in the ‘70s was simple. We just put Jason between our two seats the Bull Dog in the back and off we drove. No thought of a car seat. Before he was six months old, we had been the 700 miles to San Diego and the 700 miles to Canada. Not a care in the world and a wonderful way to see the country.” 

 

“My car was a daily driver. For the next 20 + years that was my car. As my boys grew up and learned to drive, I needed to provide a car for them for high school. Well, not my car.  So, I bought them an upgraded and modified ’71 240Z. I bought the Z because I felt they would be safer in that car. I didn’t want a larger car they would put a lot of friends in. Later on, I heard they actually had put 5 guys in the Z car.” 

 

Of course, over time, tastes changed and Richard succumbed to buying a 1992 Corvette. You know, the ones you fall into and climb out of. Fast forward to 2015 and his 240Z is in the garage, covered with the things a guy collects in a garage. The ‘vette became useless and the family all preferred the Z. This is where ZCG becomes part of Richard’s Z car journey. Let the mechanical restoration begin on this Series 1 that has not run since 1985…

Drivetrain

 

We got the original L24 with SUs running after sitting for years, but Richard wanted more power and Rob suggested a Rebello 3.1L engine. Supporting parts included an MSA 6-into-1 header, ZCG exhaust system, internally regulated 280ZX alternator, 280ZX gear reduction starter, KOYO race radiator (custom upper hose) and Z Car Garage Heat Shield. Here are a few pictures of the engine build/installation with many more in the gallery:

 

Powdercoated and plated parts adorn the engine:

 

Induction is handled by triple-Mikuni PH44 carbs on a Harada intake manifold.

 
 
 

Beneath the triple-Mikunis is our Z Car Garage Heat Shield, serial #00250:


 Before/After the engine bay restoration, more details below:

 

To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. The KA24 unit is significantly stronger than early S30 transmissions.

 
When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin). Rounding out the drivetrain upgrades are a set of Z Car Garage CV Axles (shown below)

 
 

Engine Bay Services

Richard’s Z received a total engine bay restoration. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!

 

With the engine/transmission removed we focused our efforts on restoring the engine bay.  Everything was cad plated or powdercoated.  All new fuel hoses, every cooling hose and all new hydraulic lines. Every nut/bolt is bagged and tagged before re-plating.

   
 

The Z’s body had been painted once before but the engine bay was left un-touched. We called upon our man William from William’s Auto Body re-spray the 919 Sunshine Yellow and it turned out fantastic. Before/After:

 
   
 
More before/after shots showing fuel pump, hydraulic an coolant lines:

 
 

With the new engine/transmission even more detail work was performed:

 

Final Before/After in the engine bay:

 

Our ZCG Exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip. Listen to the sound in the video below!

Dyno Tuning

 

Rob dyno tuned the Rebello 3.1L engine making a stout 199hp/221tq to the wheels. Enjoy the L-series music in this extended video of Richard’s Z including dyno runs, test drive with Rob and drive-bys:

 

Suspension

 

Richard’s chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni struts with our spring rates) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 
 

New parts included the T3 adjustable T/C rods, T3 rear control arms, T3 front/rear strut tower bars, new ball joints, new front bushings, all new bearings and seals and ST sway bars. Richard wanted a fantastic driver that was worry-free. We replaced all of the hydraulics and front/rear suspension assemblies to match the new driveline.  All suspension was either zinc’d or powdercoated:

 

Front Suspension refresh with T/C rod, crossmember and steering rack detail:

 
     

Rear end with T3 lower control arms and ST Sway bar:

 

ZCG Big-Brakes and CV Axles

We are proud to have several of our ZCG products on Richard’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) and also upgraded to Z Car Garage CV Axles! These products have been standard on numerous ZCG builds.

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We went ahead and got Richard dialed in with the ZCG big-brake kit for small wheels with parking brake and a new OEM Nissan master cylinder. More pics in the gallery!

 
 

Front brake installation:

 
 

At the rear, the OEM drums brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 130+ CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Richard’s standard half-shafts shown on left:

   
 
 

Panasport Wheels

 

Our ZCG Big-Brakes also look great behind Panasport wheels in our offset allowing us to run 225/50/16 tires (Bridgestone S-007a). The Z was fully aligned afterwards.

 

Interior

 

One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors.

 

We are really proud of the HVAC system in this Z. A vintage A/C unit was modified to work with the factory heater box and OEM controls. Our client Kurt W 3D-printed us a vent part to allow the A/C to blow cold and hard…see the video! We are working on a solution for all our customers stay tuned!

 

New, high-end carpet throughout:

 

The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:

 
 

Details

 

The little things are what we excel at. Exterior items include straightening and re-chroming both f/r bumpers. We also removed the 80’s style front spoiler and replaced it with the the correct 3-piece setup from our Series 1 parts stash:

 
We installed electric power steering, it is a wonderful upgrade see how effortless low-speed steering is in our video above!

 

Please check the gallery below for more detail shots, there are too many to list in this blog post!

Enjoying The Ride

 

In December 2020 Richard made the trek from Eureka down to Z Car Garage to pick up his restored Z. After he came back from his test drive it was quite emotional for the two Z car enthusiasts. Rob recalls…

“Richard got out of the Z and told me he had bought this Z 50 years ago that week, it’s been with him through alot of stuff and now his kids and grandkids will get to enjoy it. I looked him in the eye and said I’ll be here for their chapters, any time they need me. I’m attached to this Z now too.”

 

Richard was ecstatic. It was the reaction we live for at ZCG:

“I delivered the car to Rob and put a lot of trust in him. Nothing happens fast but what happened to my car is truly miraculous. Rob’s attention to detail is unsurpassed. It was just last December that I was able to pick up the car. It was exactly 50 years to the day that I bought the original car. It is not the Z car of yore. Rob had replaced everything. If it was bolted to the frame, all the original equipment came out. From new Recaro seats, interior upholstery replacement and sound deadening. He started up front with the radiator through new larger engine with 3 -2 barrel carburetors to tranny, exhaust system, suspension tires and wheels. It is a brand new car inside but still looks like the Ferrari I saw so many years ago.”

 

 

Richard began Enjoying the Ride in his fresh Sunshine Yellow Z back home. He sent us an e-mail of his adventures.

 “It has been a whirlwind 4 days in my life. Friday was my drive to San Jose hauling a trailer and all the while the anticipation of seeing the Z after the restoration. Saturday morning was nothing short of exhilarating. There was my little beauty, long in tooth but brought back to its original radiance. Not just radiance but purposeful modifications. What you have done with the car is truly remarkable. It is not the same car beneath that unmistakable glow.

Our visit and talk was also a highlight for me. Your exuberance is contagious. I do so love out of association. You have given me a link to my past and the wonderful times I have spent with Cheryl and my boys. So ends an odyssey that began a few years ago. I could not be happier for two reason. My car has been brought back for me to enjoy and I have made friends with an amazing man. Thank you Rob for all you have done for me.”

 

 

Richard, thank you for letting us be part of your Z car journey. We love your passion and connection to your Z. Enjoy the photo gallery and…

LONG LIVE THE Z!

Trevor’s Datsun 1978 Datsun 280Z

Filed under: 240z,280Z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 9:29 pm on June 18, 2021

 

We promised our readers a full, zcarblog.com report on Trevor’s 280Z after it was featured on Hoonigan Autofocus with Larry Chen. Let’s take a closer look at this fantastic daily driver+canyon carver showcasing our Z Car Garage Big-Brakes, Z Car Garage CV Axles, CD009 Six-speed transmission and more.

 

The Next Big Thing

 

It’s no secret that S30 chassis values have skyrocketed in the past few years. While the 240Z commands top dollar it has become out of reach for many enthusiasts. Not to worry, Datsun offered the 260Z/280Z models and both are great, attainable chassis in the S30 world. Trevor shares how he found his 280Z:

“I met my Z in almost completely stock form with 94k original miles. I travel for work, ending up in a new town every 6 months or so. As soon as I had an inkling of where I was going to be sent next, I would start hitting the internet classifieds for a 280z. While the 240z had seductive weight savings over the later versions, my attention turned to the 280z for its fuel injection (with constant travel I didn’t want to have to tune carbs), it’s price/ availability, and they are easier to find with air conditioning.” Below, left is the night Trevor bought his Z:

 

“I found my silver Z in Phoenix, Arizona. The only things it had on it that weren’t original from the Hiratsuka factory were the wheels, springs, and Toyota 4×4 front brake calipers. The rest of it was stock, and most importantly, complete. I did a little work to get it running smoother, basically replaced all maintenance items and swapped out a few sensors that weren’t working, and then drove it as much as I possibly could.”

 

Trevor was looking for a shop to take care of his 1978 Datsun 240z and heard about ZCG from a shop tour with Larry Chen on this episode of Hoonigan Autofocus (Thanks Larry!). Trevor brought the Z in last summer and we performed a full inspection before upgrades.

“I chose to send my Z to Z Car Garage after watching Larry Chen’s Autofocus episode on the shop. I could really tell that Rob had a ton of passion for what he does and I knew I could have confidence with him at the helm. Before I had showed up at the shop, Rob and I had talked on the phone about doing the brakes, control arms all the way around, and a couple of other smaller things. I wanted it to handle as best as it possibly could and that meant stopping when it should and having the adjustability in the control arms to set up a proper alignment. ” 

 

ZCG Big-Brakes and CV Axles

We handed Trevor the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We removed Trevor’s existing brakes and installed our ZCG Big-Brake kit. The stock suspension (with Tokico struts/Eibach springs) was replaced by Apex Engineered parts, as supplied by Trevor. Shown below are front/rear control arms and T/C rods being installed, more pictures in the gallery:

 
 

Front control arms and TC rods:

 
 

ZCG Big-brakes replacing the Toyota 4×4 caliper setup:

 
     
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

   
 

 

Trevor is impressed with the braking performance:

“I quickly found out that even after just a short spirited mountain drive, the Toyota brakes would get hot and fade. It didn’t help that after getting a taste for driving her quickly, I wanted to do a few track days in the future. I knew I wanted a brake upgrade, one that I would only have to do once. After getting back to Southern California I was really able to put the car through its paces on the canyon roads. The ZCG Big-Brakes proved their worth and were consistent and didn’t fade even after a few good rips up and down the mountains. This car sticks to the road insanely well. With the alignment and new tires it just carves.”

Z Car Garage CV Axles

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 130 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Trevor has CV Axle set #335. Stock half shafts (L) and ZCG units:

 

More pictures of the ZCG axles installed, also visible is the ZCG Exhaust system:

Panasport Wheels

Complementing the new Big-Brakes on Trevor’s Z are Panasport wheels! We replaced the aftermarket wheels with 16×7 Panasports and sticky Bridgestone RE-71R tires in 225/50/16. The Z was fully aligned:

Engine

We knew the car would be stopping and handling better than before, so we installed a Moroso oil pan and Koyo aluminum radiator to keep temperatures in check. Other than cooling and fuel system work, the engine was largely untouched to maintain factory reliability.

 

We replaced intake and exhaust manifold gaskets with factory Nissan parts and few ZCG tricks including a certain exhaust nut and exhaust stud.The exhaust manifold was replaced with a Pacesetter header ( to clear six-speed) leading to our ZCG exhaust system with stainless resonator and slash-cut tip.

 

Dyno Tuning

Rob dyno tuned the L28 with OEM EFI. Baseline was 133hp/149tq and with Rob’s tuning it made 143hp/159tq at the wheels:

 

Enjoy the dyno run video below:

Driveline Upgrades

We built Trevor an OS Giken LSD, a perfect upgrade for anyone doing spirited driving.

“As with the brakes, I figured the best way to do the driveline was once so I also went with an OS Giken LSD and Z Car Garage CV axles.”

 
 

We changed the final drive, installing a R180 4.11 OSG LSD built in in-house:

   
 

The clutch hydraulics were replaced to work with new aluminum flywheel/JWT HD clutch combo:

Six Speed Transmission

Next on the update list, we were really excited to install a Nissan 350z 6-speed manual transmission behind the L-series in Trevor’s Z. You read that right! S30 owners can now bolt-in this robust, 6-speed manual behind their L-series engine!  You might remember our first application of Austin Hoke’s custom 6-speed adapter kit on the OS Giken TC24B1Z-powered 240z:

 
 

Using the 6-speed conversion kit from Hoke Performance we installed a new CD009a transmission from the 2003 -2008 Z33 in Trevor’s 280Z:

 
 

Here is the brand-new transmission from Nissan being unboxed:

 

The kit necessitated exhaust header changes and after testing a variety of headers we found the Pacesetter 6-2-1 unit provided enough clearance. Serial 9 provided the shifter relocation assembly and we are really happy with its performance. Also shown is the aluminum driveshaft.

 

 

It fits! More installation pictures in the gallery. It’s a very discreet look from the cockpit…until you feel the amazingly direct and precise feel of the CD009a!

 

Trevor is in love with the six-speed, we are as well:

“I had done my absolute best to convince myself that I didn’t need a transmission swap and my wallet and I were on the same page as I went to drop the Z off at Z Car Garage. Where my wallet and I started to have a disagreement was after Rob let me take Butters for a spin. After feeling the CD009 perform there was zero chance I was going to get my car back without one on the back of my L28. However, the more I was driving the car in the twisties, the more I started to become unhappy with the uneven gear ratio gaps between shifts.” 

Details

We sorted out little things for Trevor like making his Speedhut tach and speedo functional. The car was fully detailed:

 
 

The Z was cut/buffed with a detail from JB mobile detail.  We’ve worked with Veto at JB for years and he’s a big Z car enthusiast:

 

Driving is Believing

When Trevor picked up car, he was blown away:

The car I got back is a totally different machine from the one I had dropped off. The result of the perfect combination of driveline parts is a sore face caused by either smiling the entire time or from your face almost leaving your head as Rob shows you just how well the brake kit works. Rob also threw her on the dyno and finally got the stock system performing perfectly. I’m sure it’s making more power than it did even new back in ’78.”

 
 

The Z was recently featured on Hoonigan Autofocus with Larry Chen. Larry and Rob discuss the work ZCG performed and take it for a spin. Watch the video to get an idea of the six-speed and power from Trevor’s280Z:

 

We enjoyed working with Trevor and he’s been Enjoying The Ride in his Z:

“I had flown up from the LA area where I was working to the shop in San Jose. My plan was to drive the car back down the PCH to get a feel for my new machine. I couldn’t believe how much fun the car was to drive on curvy roads. The CD009 feels great behind my L28. The shift pattern is short and precise, it’s fantastic. The rear end has no play and pairs nicely to the race feel of the CD009. One of the best parts of the combo is how easy it is to drive. It feels like you have a race car transmission but with the ease of use of a street car.”

 

 

“She’s back at Z Car Garage right now as my job has me in Omaha for the rest of the year. I have been talking to my wallet about coil overs and maybe an engine build while the car is in San Jose. My Z and I are apart right now but I cannot wait until I’m able to eat up more miles with her. She is a wicked joy.”

 

Thank you for entrusting us with your S30, Trevor. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!

Kai’s 1972 Datsun 240Z

Filed under: 240z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 5:10 pm on June 15, 2021

 

Many of our clients perform work on their Z cars by themselves, and we love to help when they are ready. Kai N installed a bunch of parts on his 1972 Datsun 240Z and got to the point where he didn’t feel comfortable taking it further. He took his Z to several local shops and was not getting it sorted so he visited Z Car Garage. We got him dialed in by sorting out his Weber carbs, brakes and fuel system. Our ZCG Heat Shield also graces his induction setup.

 

“A while back I installed triple DCOEs, headers and exhaust. I got some professional help to get the car running, but it was not quite right, so I knew my next call would be to ZCG. But before I made the call the pandemic hit, I found myself with a bit more free time and started working on other bits of the car. I ended up working on the cooling system (new radiator, electric fans), fuel system (electric fuel pump), new brakes and suspension.”

 

Z in the Family

Kai shares his Z history:

“The Z belonged to my Uncle Donnie until the late 90’s. He sold the car to our local mechanic. I’ve always wanted a Z and my Dad always reminded me where I could find Uncle Donnie’s old Z if I was ever ready to own one. When I was finally able to acquire my dream car in 2017, I asked the mechanic a few times if he would sell me the car while I was shopping for a Z, but he was on the fence about it. BTW I think he had 2 or 3 Zs at the time. After a few months of me bugging him, a generous offer and my uncle (along with his friends) putting in a few good words on my behalf, he was finally convinced to sell me the car.”

“I will never forget that after I purchased the Z, my Dad told me a story. Before my uncle sold the car to the mechanic; Uncle Donnie had asked my Dad if he wanted the Z. I was a few years from being old enough to drive and the Z could have been my first car. Of course, my Dad declined the offer. I got my Z, it just happened 20ish years (and a lot of $) late.”

 

Mechanical Sorting

 
 

Kai wanted us to address a list of items and we knocked each one out. Littles things like installing a temperature sensor, replacing motor and transmission mounts, re-wiring his fuel pump and new rack bushings were taken care of. We also sorted out his braking system and nut/bolted the entire suspension followed by a full alignment.

 

The engine bay was cleaned up, drive belt replaced and we sorted the Weber carbs. Kai purchased one of our Z Car Garage Heat Shields and we modified it to work with his throttle cable linkage:

 

More info on our ZCG Heat Shield below:

ZCG Heat Shield

We are excited to offer the Z Car Garage Heat Shield for your triple-carb’d L-series Z car. This is a one-piece 304 stainless unit with laser-etched serial number. Proven on all of our L-series engine builds and dyno testing.

 
 

This heat shield will fit Mikuni, Weber, Dellorto and Jenvey induction with several intake manifolds like the Harada:

 
 

Dyno Tuning

 

The triple Webers were dialed in on the dyno. With Rob’s tuning the Z went from running poorly to running well, making 141hp/141tq to the wheels:

 

Listen to that L-Series music on the dyno:

Kai is really happy with the work we performed:

“It’s a completely different car. It still needs work, but I can finally enjoy the car. I didn’t want a track car or a pristine show car, I simply wanted my Z to be something that I could enjoy. ZCG brought the joy. My Z’s journey isn’t done, it will continue to evolve and I’ll be counting on ZCGs help. I approached ZCG without much of a plan. I think Rob and crew formulated and executed the perfect plan for me (and my budget). The car is fun and safe, while having potential for more growth.  I had not driven the car in 2 years, So I’m sure you can imagine how happy I was.”

 

What’s next for Kai’s Z? He’s driven Mrs. Butters, our 1971 shop 240Z and he is returning to ZCG for our ZCG Big Brakes!

“My experience at ZCG has been amazing, I’m pumped for the next step in my car’s journey. ZCG BBK is next for me! Also being at the shop is cool too, there is always something there that blows my mind (like the BRE Z or the IMSA).”

 

Thanks for your support Kai, we are honored to be a part of your Z car journey!





 

On May 1-2, Sportscar Vintage Racing Association (SVRA) hosted the Trans Am Speedfest at Laguna Seca. Z Car Garage was fortunate to participate and support several client’s Datsun 510 race cars running in B-Sedan Group 8. It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with photos and exclusive in-car footage!

Z Car Garage Supports Three Datsun 510s!

 

It is our pleasure to bring more enthusiasts into the world of vintage racing. Our services do include full race support and car-preparation to help make client’s race days seamless and worry-free so they can focus on driving. One of our specialties is dyno tuning. Before a race weekend we confirm that your car is running well and make necessary adjustments while on the chassis dyno. Below is a video of two Datsun 510 B-Sedans (Rob and Tom) and Kelvin in the second video on the dyno prior to the Speedfest weekend. Enjoy the sweet L-series music!

 

510s Galore!

With ten Datsun 510s in Group 8 it was a Dime-lover’s dream to be in the paddock and watch the races. Although the event did not allow spectators, we’ve got you covered!

Let’s take a look at the Datsun 510s that we supported, beginning with our clients. All of our cars ran flawlessly:

#7 Kelvin Tse

 

Here is Kelvin’s re-telling of his race weekend with us:

“Driving Laguna Seca during the spring time is a wonderful experience in itself. Racing Laguna with other B Sedans in a well prepped 510 is a racers high on another level. Track conditions were perfect with sunshine and daytime highs in the mid 70’s. The weekend was uneventful as far as mechanical problems were concerned a fact that has not always been the case for me. 5 years and far too many let downs.
I have really never had a 510 that I felt like I could just drive at the limit with a fair degree of control.  Z car garage has given me a proper race car. MOTOR, TRANSMISSION AND SUSPENSION have been sorted out and now the car could be driven at the limit. I finally was able to trust the car to steer correctly after full compression of the shocks and springs. The car was very predictable . I have also been working on getting use to the new dogleg transmission installed recently and finally have learned how to properly downshift thru the gears. 

 

Saturday Race I started in position 8 and had a battle for every corner with David Murray in his BMW 2002. We pretty much changed positions for every lap. I was excited to have a car that I felt comfortable enough to go door to door racing with. David said that this is the best race he has had in years and I have to agree with him as we were duking it out. On the last lap, he left the door slightly open entering the Wayne Rainey curve and I took it. After passing him I knew that he would try to set me up for turn 11. Well, he did put his nose in there, and we both got thru 11 with me having a slight advantage. Drag racing down the straight bumper to bumper … Yep , the 510 came out ahead. Position #7

Sunday morning … a mix up with SVRA tech paperwork DQed me and put me at the back of the grid. I was listed as a 2L and need more weight to qualified as a 2L.Problem… My car has a 1800cc.  In fact I could still loose a 100lbs. hey Rob and Josh next project….

Starting at the back of the grid was not where I wanted to be. So my start was going to have to be something else. Years of racing cars and karts have helped me on my starts. Well , I did get a good jump when the starter started to move his hands up. I dived all the way to the right of the track in turn one kicked up a little dirt and put the car exactly where I wanted on the outside of turn two (SEE VIDEO BELOW). Full power on the inside of turn 3 made me go from the last position to position #6 behind Tom Dockery. Whew…that was fun…We only got in 2 laps before the race was red flagged because of an Alfa who’s driver got out of his vehicle in turn 5. A big no no… Position #6

Overall, Rob was the winner, Tom finished #5 and little old me got a #6.   I am still developing and learning how to drive this wonderful car. But what strikes me as a successful weekend is when everything just seems to go your way, the sun is shining and you are out with some great friends having FUN!!! This was accomplished only with the help and support of everyone at Z Car garage. The racing gods were smiling at me this weekend.”

 
 

#72 Tom Dockery

Tom Dockery drove his Ex-Norm Balzer/Koobation 510. This car made its debut in May 2019 and we are excited to share its full story and profile Tom’s journey into racing.


Tom had a blast here are his thoughts on the race weekend:

The SVRA TA Speedfest was so much better than I expected.  Coming in I set myself up for disappointment, mostly because my last experience on Toyo 888Rs was so disappointing, almost scary. But my first practice flushed those fears away. In the first practice I beat my previous PR, breaking the 1:50 mark which I did earlier in the year on fresh R7s. Over the course of the weekend, I continued to set new PR’s finishing up on Sunday with a mid 1:48. I think the trick was me continuing to get comfortable with the new engine and the idea of sliding though a corner. There might have been some additional benefit of the small diameter Toyo tire giving me a final drive the fit really well with my speeds at Seca.

 

The run group was large with a strong mix of 510’s and 2002s.  GTV accounted for just 2 of the 35 cars. Strangely the field set up with all the 510’s qualifying ahead of the 2002s for the most part. My experience with Steve Walker and John Murray suggests this was probably just drivers and not cars.  Although I was able to keep reasonably attached to the top five cars (though Troy and Rob were pulling away at a steady rate) I really enjoyed watching my rear view in car video as Kelvin and I pulled away at a pretty good rate from the rest of the field ….. that was fun.
My car was perfect, no issues and ran in top form all weekend long thanks to Josh and Rob.”

 

In-car video is the Sunday afternoon session from Tom’s 510, enjoy: The rear facing is cool because of Kelvin’s go-kart talents and near Troy-like start behavior. The front video I thought was encouraging has I was able to keep a line of sight and partial contact with people who historically have been much faster than me.-Tom

#7 Rob Fuller

With the assistance of ZCG crew Josh and Keith we also supported ZCG owner Rob Fuller in the Bay Area Datsun Dealers tribute car:

 

Rob performed admirably with a fastest time of 1:44.068, here is his experience:

“SVRA is mostly an East coast association, coming out West a few times a year so we were happy to be a part of their events. This year they did back-to-back events with a weekend at Sonoma (unable to attend ) and Laguna Seca April 30-May 2. We supported three cars with Josh as crew and myself as driver/crew. All had a great weekend with each car running really well. SVRA rules require us to run a Toyo R888 tire, not as sticky as Hoosier R7s we typically use. Dockery and Kelvin finished in the top 10 with personal best lap times, I am really proud of them. On Saturday I finished right behind Troy Ermish.

   

Race 2 on Sunday was dramatic. Wherever you finished Race 1 is where you start in Race 2. Troy and Rob were just .002s apart in qualifying!

“To be close to Troy was fun, because he can drive like hell. In Sunday’s race both of us were out in front, a good 3 seconds ahead of the 3rd place car when suddenly an Alfa oiled down the track outside of Turn 4. I saw Troy’s car move around, and then my car got loose. As he moved into turn 3 I a saw strip of shiny oil across the whole tack and as I changed my line to avoid oil I watched Troy go off outside of Turn 4. Most drivers would have tried to correct this and probably hurt their car…not Troy! He drove right through it, foot to the floor dirt-track style. For the next laps I didn’t look in my mirror,  just drove the defensive line and hoped I could stay in front…as we approached Turn 11 I could see Troy throw his car into the turn but overcook it…we finished under yellow flag.”

 
 

Rob got the checkered flag finishing in front of Troy and took First place on the podium, though not under ideal circumstances…

“I don’t take it as a real win, even though I placed ahead of him. Troy is an amazing driver and I love the challenge he brings. I hope to enjoy many more races with him, under green flag conditions.”

You can see in-car footage of Rob below:

The Race 2 Results:

 

Thank you!

 
 

We hope you have enjoyed our report from the 2021 Trans Am Speedfest! SVRA did an amazing job with the event running like clockwork considering the sheer number of race groups. Kudos to them for excellent safety and organization. We hope October’s event with CSRG will be open to spectators!

*See you in October for the CSRG Charity Challenge in Sonoma!*

Vince S called Z Car Garage after he scored this 1973 Datsun 240Z from our friends at Bring a Trailer. After we got the Z up here from SoCal we found that it needed some work for Vince to really Enjoy The Ride. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with a full suspension refresh and engine tuning make it just right.

 

Z Destiny

Before we explore the upgrades, let’s take a look at how Vince found his Z car…

“I’m incredibly lucky to own my Z. It was sold new in Decatur, IL on August 10, 1973. The car was supposedly purchased from the 2nd owner who reportedly had it for over 30 years in 2018 by a dealer in Oakland who then sold it to the collector I bought it from. I first saw the car in 2019 parked in my neighbor’s driveway. At the time, I was looking for a 240Z to buy. In high school I had a 1978 280Z that I took to college but it was prone to overheating and I blew a head gasket and didn’t have the money to fix it. I sold it in 1990 and regretted it ever since. So, when I saw a 1973 240Z sitting in that driveway, I knocked on my neighbor’s door and asked if he wanted to sell it.”

“Turns out the Z didn’t belong to him. He was transporting it from Oakland to Carmel and then on to L.A. for a friend who was a collector. The friend already owned two 240Zs (he has one of the 37 Zs that were part of Nissan’s Vintage Restoration Program) and he wanted my Z for it’s a/c components and other bits to complete one of his cars (he later decided it was too good of a car to use for parts). Although I couldn’t buy my Z that day, my neighbor let me go for a quick drive around the block. Fast forward to April 2020 and that very same Z is being auctioned on Bring a Trailer.”

 

Vince watched the auction, confirming with the seller that it was the same car he had driven. Although he was outbid, 20 minutes after the auction ended the seller informed Vince that the winner backed out. They agreed on a price and he became the proud new owner of the 240Z.

 
 

Chassis and Suspension Upgrades

 

With Vince’s Z finally at the shop we proceeded with upgrades to make it a fantastic, reliable driver. For our clients that are cruising with occasional “spirited” driving we installed our “Stage 1/light street” suspension.  New parts from Techno Toy Tuning included adjustable T/C rods and rear lower control arms. We really appreciate Gabriel and his staff at T3. They make some of the best suspension parts out there for Z cars.


A full front suspension rebuild included new rack bushings, front control arm bushings, ball-joints, tie-rods, new wheel bearings front and rear (OEM genuine Nissan seals/parts), KYB strut inserts, Eibach lowering springs trimmed Macpherson bumps stops for full travel and a ST sway bar set.

 
 

ZCG Big-Brakes and CV Axles

Brakes: every vintage Z car that we build here gets the ultimate setup: our Z Car Garage Big-Brakes for small wheels.  Everyone that drives our 1971 Series 1 240z shop demo car is sold on our Z Car Garage Big-Brakes  and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below: Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized) Rotors: 280mm x 20.6 with Alum 7075 hats Pads: Stoptech 309 sport street pads Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. A few closer detail shots of the calipers, rotors and hardware:

 
 

We removed Vince’s brakes and installed our ZCG Big-Brake kit with a new brake master cylinder from Nissan, rebuilt brake booster and parking brake assembly.

 

New brake master cylinder from Nissan and stock vs Big-Brakes:

 
 At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 90 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Vince has CV Axle set #341. Stock half shafts (L) and ZCG units:

  
 

ZCG CV axles installed:

 

Panasport Wheels

Complementing the new springs and shocks on Vince’s Z are Panasport wheels! We replaced the stock steel wheels (kept for shows) with 16×7 Panasports and Continental Extreme Contact Sport tires in 225/50/16.

 

 

Drivetrain

We performed a full drivetrain inspection with compression/leakdown test to make sure the engine was healthy. A list of items that were addressed/replaced: sparks plugs, new plug wire set, fuel filter, valve cover gasket, valve adjustment, MSA 6 to 1 header to our ZCG exhaust system and Z therapy carbs. More pictures in the gallery!

A Koyo race aluminum radiator replaced the stock unit:

   
 

All coolant hoses were replaced, new water pump, fan clutch, fan blade, all new drive belts, new battery hold-down/cables and a e…we even lubed chokes cable everything to make this car a solid driver… everything to allow Vince to just hop in to his vintage Z and enjoy some back roads. The aging 4-speed transmission was replaced with a 5-speed from our parts stash.

 

This early 280z 5-speed. came in the 1977-78 S30s and has the same gearset with an 0.86 overdrive perfect for the factory rear end. Our go-t0 JWT alum flywheel/clutch back the engine:

 

Dyno Tuning

With fresh Z Therapy carbs and MSD Blaster 2 coil with Pertronix ignition Rob set the AFR/timing for best performance and drivability. Rob dyno tuned the L24, now making 138hp/139tq at the wheels:

 
 

Vince is throughly impressed and happy with all of the chassis and engine upgrades:

“My experience with Rob and ZCG has been exceptional. When I bought my Z, it was essentially stock with the exception of one or two paint resprays of the 113 green and an added electric fuel pump. It was clear the car had a fair amount of deferred maintenance, I knew I needed to improve both its drivability and reliability.  So, I upgraded to the ZCG Big Brakes, ZCG CV axles, did a full suspension rebuild and drivetrain refresh.  Well worth the wait…The Z I picked up was nothing like the Z I dropped off — it was better in every way.”

Enjoying the Ride

 

We loved to hear that Vince is out an about with his Z. He attended the Valt gathering in Albany where our friend Geoff snapped these pictures. He also just completed a rally with Breakfast Club Rally group:

“The 2nd best road trip was a recent 100 mile rally in the east bay foothills and my daughter rode with me for that as well. She shares my love of cars and passion for Zs. It reminds me of the times I shared with my dad who could fix anything on wheels and for years owned his own repair shop. That’s why this Z is so important. As much as I appreciate the beauty of its design and brilliance of its engineering, it’s the memories I have and will make that I cherish most”

      

Welcome Back to the Z car family!

“My Z performs far better than I expected. I just did my first 100-mile rally and had complete confidence that the car would go, turn and stop like I needed and expected it to. This isn’t my first Z but it’s my first 240 and first major mechanical refresh of a car. As they say, “you don’t know what you don’t know,” so I really valued (and needed) Rob’s experience and advice. My Z means a lot to me (my daughters joke that she’s the favorite in the family) and it was important to do things right. It’s not that money wasn’t an object but I was willing to invest in the things that mattered most, which is what Rob and the crew helped me do.”

 
Thank you for your support and we loved working with you Vince!  Happy that you are a Z car owner again, welcome back to the family and LONG LIVE THE Z!
