Z Car Garage specializes in restoring and maintaining the S30 Z car. We love stock examples like Vince’s just as much as modified cars. Vince contacted us and patiently waited in the queue to get his Z at the shop:

“Searching online for someone that I could trust to repair my Z, I came upon rave reviews from other owners of Rob at Z Car Garage and reached out to him. Rob asked that I email him pictures of my car, particularly the engine compartment, to determine if he could help me, and within 5 minutes, Rob called me back. I immediately recognized that I found someone who not only supremely understands Datsuns, but also shared my enthusiasm and passion for keeping my Z on the road.”

Z History

Vince’s Z Journey began when he first started driving in 1974:

“Our High School P.E. teacher doubled as our driving instructor, and while we were learning to drive Dodge Monaco Sedans, his daily driver was a 112 Yellow (Lime) ‘73 240z. I asked him what he thought of his car, and he responded: “It’s the best car I have ever owned.” That’s all I needed to hear, and soon found myself at the local Datsun dealership in Millbrae California. There on the lot was a ‘72 240z, 4-speed, white on red, with only 33,000 miles on the clock. The dealer reluctantly took me out for a test drive and this 15-year-old was forever hooked. Great styling, smooth power delivery, a flawless gearbox and only two seats, which thankfully guaranteed that my car would NOT be chosen to endlessly cruise with my buddies on Friday’s and Saturday’s, usually ending with an interior filled with spilled drinks and food.”

Vince has since owned 300 different cars, but there has always been a Z in his life. His current Z is a ‘72 240z, 4-speed, 110 Persimmon Red, white interior, acquired 5 years ago, with a California only history. The car had a cracked dash with a glued-on cover, a clock that did not work  and original carburetors that badly bogged down while accelerating. It was time to get Vince back on the road.

New Dashboard

We removed the old dash assembly and performed clean-up work in preparation for the new Vintage Dashes unit. More pictures of the process in the photo gallery!

 

The heater box was refurbished with new heat/defrost vents, gaskets and all HVAC cable controls were lubed:

Ducting and completed heater going back in:

Since the dash was out we had access to the heater core which got pressure tested and serviced. All coolant hoses under the dash and in engine bay were replaced:

Every single bolt was replaced in the dash and the gauges refreshed. The clock was replaced and functions perfectly.

The completed Vintage Dashes dashboard and assembly ready to go back into Vince’s Z:

“As for my dash, I had several options but settled on a newly manufactured replacement dash from Vintage Dashes, minimizing downtime, and allowing me to keep my old dash in case I wanted to restore it. I trusted ZCG to take apart my entire dash and EVERYTHING connected to it. The result is a dash that looks like new (because it is) and everything connected to it working properly, including the clock, which by the way keeps excellent time.”

Engine Bay

A new set of SU carbs from Z-Therapy were installed along with all new fuel hoses and fuel filter:

Enjoy the Ride!

Vince is a great guy and a great Z car owner. He made this video showing his Z after the work ZCG performed, enjoy!

We love making our clients happy:

“My goal for this car was quite simple, I wanted a 1970’s time machine that I can use as a weekend driver, with the operative word being “use”, because in my humble opinion, Z’s are meant to be driven. Except for the carbs, the car was mechanically sound, but I wanted it to run like it should. I was also tired of looking at the dash cap, and wanted to have everything in working order, like it did in the 70’s, including the clock…”

“…In fact, everything works and runs so flawlessly, my car with 92,000 miles runs better than the 3-year- old Z I drove off the dealer lot back in 1974, a testament to Rob and ZCG. It feels good to be back in the 70’s, even if only on weekends. Thanks Rob, and long live the Z.”

Thank you for your support Vince, and yes, LONG LIVE THE Z!

It really makes our day to see a client still enjoying their Z years later after visiting Z Car Garage. Last weekend we saw Michael D’s 1972 Datsun 240Z at the 34th Annual Z Car Convention (ZCON) in Colorado Springs, and it reminded us how we’ve worked with him since 2007. Let’s take a closer look at this Nissan RB25DET-powered S30 featuring our Z Car Garage Big-Brakes, Z Car Garage CV Axles, full suspension and Panasport C8 wheels.

Go Green Inspiration

In 2005, Rob Fuller performed an RB25DET engine swap into his 1970 240Z, affectionately named Go Georgia Z (GO GA Z = Go Green Georgia Z). The RB is a turbocharged inline-6 engine from the Nissan Skyline (R33) GTS-T in Japan, requiring new drivetrain mounts and supporting modifications to work in the S30 chassis. Once completed, Rob drove his Z all over California, attending several long distance car shows like Motorsport Auto in SoCal and the All-Datsun Meet at Mt. Shasta.

Rob’s RB-swapped Go Green Z gained notoriety and around 2007 is where our relationship with Michael began. He wanted ZCG to do an RB25DET swap similar to Rob’s in to his super clean ’72 240Z:

As we know it’s always been tough to keep up with demand at ZCG. Mike is a great guy and kept offering us his business but Rob wasn’t ready to take on the project. Instead, we focused on preparing his car to handle the RB swap. Driveline upgrades included a ZCG-prepped 4.38 R180 LSD (since replaced with R200 3.55 Quaife LSD), restored hydraulic/brake lines and our ZCG Big-Brakes and CV Axles.

After the RB swap was completed in 2013 at another shop, Michael returned to Z Car Garage to sort a few more items. We did not like how the fuel system wasso it was redone by us. We also sold him our custom ZCG (Z31) motor mounts and tunnel bracket reposition for the OEM RB25 OEM transmission.

A few specs on Michael’s current setup: RB25DET rebuilt with RB26/Neo/N1 parts, BorgWarner EFR 7670 turbo, GTR coil set, Bocsh 1000cc injectors, TIAL 50mm BOV, McKinney Pan and Radiator, Wiring Specialites Harness and a LINK Ngtr+ EMS. With 525whp/480ft-lbs, the suspension and brakes were upgraded. We installed a full Ground Control coil-over suspension (remember this was in 2008) and Michael reports great performance still:

“In regards to the performance of the suspension upgrades, coil-overs, Tokico struts/shocks I was considering T3 and Arizona Z control arm suspension replacements. My suspension performs so well with the stock A-frames etc that it didn’t make any sense to change them. I would add, without spoilers my 240z stays very grounded at 130 mph and I know what I am talking about after having owned a ’14 R35 GTR for 7 years.”

Z Car Garage Big-Brakes and CV Axles

To cope with the power of the RB25DET, Michael has our ZCG Big-Brake kit. Not to be confused with our current Z Car Garage Big-Brakes (for small wheels), this Big-Brake kit was our initial setup from over a decade ago. This 328mm sized kit requires 17″ diameter wheels and the massive ST-42 calipers are finished in bright red. We actually did all the R&D in-house for this setup…using a 280ZX master cylinder and our own mounting brackets.

Since it was in its infancy we did not market or sell this BBK to the public, installing it only our clients vehicles. There are about 20 sets of these early, 328mm BBKs on client Z cars like James’ Turbocharged L-Series 240Z, Scott’s 260z, Gary’s Datsunworks-Powered 240Z and Lou’s RHD FairladyZ:

Panasport Wheels

Michael also got a set of our custom Panasport Racing C8 wheels. These 3 piece, 17×9 wheels allowed fitment of a 255/40/17 tire under stock fender flares.

When ZCG was starting to build a series of RB-powered S30s, Rob brought in a pallet of C8 wheels destined for the builds. Michael wanted a set so we hooked him up with a silver spoke finish. They look great on his Z:

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.

 

We built Michael a set of CV Axles, shown below:

Interior

Michael is proud of the interior on the Z, keeping it aesthetically close to stock with updated materials and comfort in mind. A Restomod A/C unit keeps things cool. A very special thanks to Luis at Vargas Auto Upholstery:

“Sewed in centers of original seats, Auto Meter digital speedo and tach to modified to look original in original housings, the dash which is impossible was done with requirement to minimize stitches and never cross a stitch, stereo housing was built to match the faceplate of original, has remote electric windows and locks, power steering, hands free phone, android auto for maps, and seats that hold you in while providing comfort for 8+ hour drives.”

 

Enjoying the Ride

Michael contacted Rob in 2003, just after he purchased his 60k-orignal mile 1972 Z to get the upgrades started. He’s driven it since 2004. Here is what it looked like when he picked it up, and a current photo:

Michael’s goal for the build, aptly named “TRBUTEZ”…

“It is called TRBUTEZ.: A tribute (act, statement, or gift that is intended to show gratitude, respect, or admiration) to the many under $3k  starving student Z’s I owned that carried me through life with unconditional loyalty, performance, and dependable reliability. This one is for you. Thank you!  My goal is to upgrade the build of the car for an even better personal experience while maintaining the respect this car deserves through preservation of every original detail possible.”

We were stoked to see Michael and his Z at the ZCON event on Colorado Springs. After all these years he’s still Enjoying The Ride!

When you think it couldn’t get better…he won (4) awards!

Thank you to ZCON organizer Christopher Karl and Meghan Fuller for the show photos! More in the gallery below.

We have several exciting projects at the shop that will get full reports on zcarblog.com but today we want to highlight a few cars that we prepared for next week’s ZCON event. Please tune into our Instagram story for more sights and sounds as we have Z32, R35, S30, 370z, 350z, S130 and yes, even some Z31 updates heading your way!

ZCON Here We Come!

Z Car Garage is proud to be a sponsor for the 34th Annual Z Car Convention (ZCON) hosted by ZCCA in Colorado Springs 8/16-20. This is the largest Z-car event in the US and we are stoked to participate. Here are three client cars destined for ZCON, enjoy!

The OMS Pace Car

This is a 1972 Official OMS Pace Car Duplicate. It is at present one of only two known survivors . Fifty were originally produced by Nissan Motors to commemorate the DATSUN 240Z being selected by the Ontario Motor Speedway to Pace the 1972 “U.S.A.C. California 500 Championship”.  It really is a small Datsun world, as the official OMS pace car is none other than our very own Joel Anderson #49 IMSA GTU 240Z .

This OMS duplicate belongs to our long time customer and friend Linda. She acquired it from a family in SoCal and tasked ZCG with making it a nice driver. Full report soon but it got loaded up today for its journey to Colorado!

Jack’s LS3-Powered Z32

Jack and Yolanda have been a part of our lives since the beginning of ZCG. Being long time members of The Z Owners of Northern California (ZONC) and supporting our shop along the way, we are grateful to them. ZCG will be restoring the Primadonna Z back to its former glory this year! We are also helping the couple finish their LS3 V8 engine swap into their “Primadonna” Z32 Convertible. Yes, Jack had to get back in the game after building those 240z cars so he built a Z32 body kit from scratch. Like the S30’s he built, this widebody Z32 has evolved over time:

 

 

ZCG finished the LS3 swap and dialed it in with road-testing and dyno tuning.

It even sports full A/C and OEM shifter for the automatic transmission. The Z was loaded up with the OMS pace car today and heading to ZCON, full report soon!

Mike’s Datsun 240Z #193

Mike’s vin # 193 Series-1 S30 was ZCON bound but needed further work to be truly show-worthy. We love that he’s on board with us to finish the car correctly. It’s a beauty and it will be sensational.

Z You There!

This will be an eventful week for us. ZCG will be attending the Rolex Monterey Motorsports Reunion this weekend, then it’s on to New York for the Global Reveal of the New Z and finally we will be in Colorado on Friday for ZCON! We are stoked to see the cars, faces and meet new people. Watch our IG/FB and twitter for updates!

LONG LIVE THE Z! Check out our Instagram story for more updates!

Z Car Garage is excited to collaborate with Datsunworks and develop their brilliant KN20 dual-overhead cam (DOHC) cylinder head designed for the Nissan inline-6 L-Series engine.

Datsunworks founder Derek Minetti is the pioneer behind the KN20 DOHC cylinder head. This is a custom (very limited production), 6-cylinder head derived from Honda’s venerable K-series 4-cylinder engine. The KN20 offers superior head flow rates combined with modern valvetrain components to effectively transform your L-series single-overhead cam into a high-revving, dual-overhead cam engine. The power potential is impressive.

Gary’s Datsun 240Z

There are ten KN20 heads in the wild with only three installed and currently running in cars. Z Car Garage has two KN20 cylinder heads. This KN20 is serial #SN10 and it has been installed into our long-time client Gary’s Datsun 240Z, affectionately named the “Behemoth”. ZCG is always exploring the boundaries of powertrains and Gary’s Z has seen a few engines including an RB30DET, OS Giken TC24 and now the Datsunworks.

Here are few details on the powertrain setup for this Z:

-Rebello 3.1L Engine

-KN20 Cylinder head SN10 (but the performance level goes to 11)

-Induction type: Jenvey ITB EFI with Injector Dynamics injectors

-Engine management: Haltech Elite 750

-Header: Equal-length, custom fabricated by RacecraftNW

-Transmission: Nissan CD009a

-Rear Diff: R180 4.11 OS Giken LSD

Pictures of the initial engine installation, with more in the gallery:

For further information on the KN20 cylinder head we urge you to visit the Datsunworks blog:
Datsunworks Blog

Performance

We are still in the tuning phase so Gary’s car is on a comfortable (conservative) setting. With the Datsunworks head it made 350hp/248tq at the wheels on 91 octane:

Even in a testing stage it is absolutely thrilling to drive. Gary’s car is a full ZCG-style restoration so it has the chassis to harness the power. The sound it makes is a sonorous tone only the K-series derived KN20 head creates…with a gnarly exhaust note to match. The ITB induction also provides a healthy wail…it’s a sensory overload and revs seem to climb endlessly.

To illustrate the Datsunworks experience we captured some video of what it is like to drive around town…the 6-speed and EFI really allow this car to be docile, especially when cruising on the freeway and at part throttle. Drop a gear and its becomes a wild animal. Not going to lie…it gave me goosebumps both as a passenger and spectator.

Watch the video complete with multiple dyno passes, street acceleration and fly-bys. VOLUME UP!

Potential

Z Car Garage is stoked to be a part of the Datsunworks KN20 development. It is a clever design that pushes the envelope for L-Series engines. Sharing this experience is also part of the fun so we anticipate having a KN20 setup in a dedicated shop 240Z for clients to test drive and further evaluate. Although each application is different, we envision offering a bolt-in setup for your six-cylinder L-Series engine. The power potential is tremendous with the KN20…both NA and forced induction. We thank Derek at Datsunworks for giving us the opportunity to work with this innovative product.

Stay tune for more updates and LONG LIVE THE (TWIN CAM) Z!

The stories behind every Z car and their owner play a huge part in our love for keeping them on the road. The Nunes family has owned this 1978 Datsun 280Z 2+2 from new, starting with Gilbert and soon to be passed on to his son Dillon. This S30 was treated to a ZCG-style mechanical restoration including a new drivetrain, engine bay restoration, our Z Car Garage Big-Brakes and Z Car Garage CV Axles, total suspension rebuild and more.

.

We admire the 280z cars (see Cece, Greg and the Roth’s builds) and met with Gilbert to discuss his needs. Updating the Z while preserving the exterior patina was the vision. First, let’s take a look at the Nunes’ family history with their Z.

From Father to Son to Grandson

Gilbert recalls how he got the Z:

“It was Christmas of 1977 and my parents decided to reward me for doing good during my first year of College at San Jose State. On Christmas Day by surprise I was handed a little box with keys in it. They knew I wanted a sporty car, but they had their own requirements. My dad wanted it to be an automatic, and he wanted a back seat so our whole family could fit in the car. The first attempt at buying a 280z didn’t work because of a dumb salesman at Downtown Datsun…

 

…They went there and asked to look at the Z’s however the salesman didn’t want them to buy a Z thinking they were too old for one. So they went to Stevens Creek Datsun and found a salesman who was dying to sell a car since Christmas was close. So in no time at all they found a automatic 280Z 2+2. I had no idea of the color or exactly what I was getting when I pulled up to the dealership, but I was very happy with the car.”

  

Gilbert would daily drive the Z that he got from his parents for 30+ years. His son Dillon grew up in the back of the 2+2 and has fond memories:

“My dads 280 is actually still in his possession, it will be left to me some day. I have a lot of stories from growing up in this car, mainly being a little kid and my dad letting me ride in the backseat with no booster seat because the seats are small enough. I remember of my dad driving my sister through a decent sized flood making sure she made it to her piano recital, all in the Z…

 

…I was very excited about getting my Dad’s car restored (it’s something we have literally talked about for 20 years). I’m not sure how he heard of Z Car Garage but I know I have been going there almost all my life. My earliest memory at ZCG was at a Friday car meet (Our 5th Anniversary gathering) where bbq burgers and hotdogs were being served. I was about 12 years old, and loved seeing all the Z’s and other Nissans, especially the GT-Rs.”

The Nunes family dropped off their beloved 280Z at the shop and the transformation started.

 

Drivetrain

Gilbert’s Z received a total engine bay restoration along with upgrades to the driveline for smoother driving and improved torque. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!

Engine

 

A fresh 2.8L  “street” engine with replaced the tired L28 (above), new L28 below:

   With the engine/transmission removed we focused our efforts on restoring the engine bay. Everything was zinc plated or powdercoated. New parts included brand new injectors, all new fuel system, hoses, fuel filter and all the drive belts.

 

Intake manifold cleaned up and powdercoated:

 

An MSA exhaust header was installed. Powdercoated and plated parts laid out for installation. We bag/tag every nut and bolt:

 

All new hydraulic lines, emissions plumbing and more engine bay clean-up (full re-paint by our man William) before/after. More pics in the gallery!

  

More detail work:

 

Engine bay restoration, before/after:

   

Suspension

 

Gilbert 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:

  

We installed KYB strut inserts with lowering springs, Suspension Techniques sway bars, Techno Toy Tuning adjustable rear lower control arms, TC rods, and rack bushings, all new wheel bearings and new ball-joints. We do offer a full coil-over setup for track day/performance-oriented customers, and this spring/strut upgrade for those that want a better stance with improved handling without getting beat up.

ZCG Big-Brakes and CV Axles

We are proud to have several of our ZCG products on Gilbert’s 280z. 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 Gilbert dialed in with the ZCG big-brake kit for small wheels with parking brake and a new brake booster/master cylinder. More pics in the gallery!

  

Front brake installation:

 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 130+ CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Gilbert’s standard half-shafts shown on left and ZCG CV Axles on right. Also note plated brake lines:

 

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). Gilbert really wanted black so we had the spokes powdercoated in black with the polished lips cleared…they look sharp!

 

Details

 

The little things are what we excel at. The rear differential was refurbished. All electrical connections re-done. The original A/C system was retrofitted to use R134a refrigerant and made to blow super cold. New battery cables and wiper blades. We also replaced all of the fuel vapor hoses in the hatch. Please check the gallery below for more detail shots, there are too many to list in this blog post!

Enjoying The Ride

 

Gilbert’s son Dillon came down to ZCG pick up the 280. He was impressed:

 

“As far as how the car performs, its amazing. I have taken the car on a few drives and from my perspective the car corners like its on rails and stops on a dime. I took it up Sierra road and had a blast, still waiting to take it up highway 9. I was also surprised by how smooth it was driving on the freeway to a car meet at the USS hornet. With the stiff suspension I expected an unpleasant ride all the way to Alameda but was pleasantly surprised at how smooth it was cruising at 85mph on 880. My only complaint is the auto trans, I would personally prefer to have it converted to a 6 speed that I have seen on your blog but my dad hates manuals:(“

 

Dillon and the Z at the local VALT Cars and Coffee in Alameda:

Here is a short video from Dillon shortly after picking the Z up:

Gilbert is enjoying the Z as well!

Thank you Gilbert for letting us re-birth your Z car. It makes us happy to see it being driven and soon passed on to your son Dillon. ZCG is honored to help keep the family Z on the road.

LONG LIVE THE Z!
