At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goal a reality is our passion. Beau brought his 1976 Datsun 280Z from Castro Valley, Ca for a full cosmetic and mechanical restoration, ZCG-style.

 

Our Z Car Garage Big-Brakes, Z Car Garage CV Axles along with a new drivetrain, full suspension and body restoration transformed this S30. Before we explore the work performed, let’s take a look at how Beau found the Z car of his dreams…

Z Beginnings

 

BEAU: I am the second owner of the car – the original owner passed away and the children decided to sell the car. I saw it posted on Craigslist and knew immediately that this was the car for me. My brother-in-law took it on a test drive and it performed great, appeared to be in good condition – no rust, dings or signs of being mistreated. The owners told us that there were several interested buyers but the first person to show up with cash would get the car. We scrambled to quickly find cash at 6 PM in the evening and headed back to purchase. 

 

The Z Car Garage Touch

 

Shortly after acquiring the car in 2018, Beau joined the Z Owners of Northern California (ZONC) and asked for recommendations on a mechanic.

BEAU: Everyone that I spoke with recommended that I connect with Rob. He is an artist – not just a mechanic. As such, the process takes time and involves patience. That patience is rewarded with a car where all of the details are considered and thought through. Rob listened to all of my requests – a car that looks like it came off the factory floor in 70’s but with performance, handling and upgrades that reflect what is possible today. 

    

 

BEAU: I wanted to note that we’ve named the car, “Orange Julius”  – somewhat inspired by Larry Chen’s Ole Orange Bang and Randy Jaffe’s Rocketbunny Z  which I saw at Z Car Garage and was floored by the color. The process took nearly 3 years and I endured a lot of questions from friends and family about when the car would be done – my patience was rewarded! Thank you Rob!

 

Drivetrain

 

Beau acquired his 280Z from the original owner with 50k miles. We started a mechanical overhaul so he could enjoy driving it. A 4-core radiator upgrade is something we do anytime a car has an automatic transmission along with cooling line replacement. Beau wanted more power so the stock L28 was bored and stroked to 3.0L by Rebello with forged pistons and light port work:

 

With the engine/transmission removed we focused our efforts on restoring the engine bay. Everything was zinc plated and powdercoated. New parts included brand new injectors, all new fuel system, hoses, fuel filter and all the drive belts. The 3.0L still utilizes the factory EFI and intake manifold that was cleaned up and powdercoated:

Engine bay restoration, before/after:

 

We installed our full ZCG Exhaust system with slash-cut tip:

 

Dyno Tuning

Rob dyno tuned the Rebello 3L/Automatic transmission making 161hp/175tq at the wheels, a significant gain over the stock L28:

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 200 CV axle kits on customer cars and we are stoked with all of the positive feedback. Stock half shafts and Beau’s ZCG units shown below:

   

Suspension

 

A full suspension refresh was performed, including coil-overs (Koni), T/C rods and control arms 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.

 

All front and rear suspension parts were powdercoated:

 

We bagged/tagged every nut and bolt for plating along with fresh hydraulic lines for the chassis:

   

Z Car Garage Big-Brakes

We are proud to have several of our ZCG products on Beau’s 280z. We installed our Z Car Garage Big-Brakes (for small wheels) which have the been standard on numerous ZCG builds.

     

Stock disc/drum brakes  were removed and we installed our ZCG Big-Brake kit.

   At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. New OEM Nissan master cylinder and Factory handbrake functionality IS retained!

    

Panasport Wheels

Complementing the new coilover suspension on Beau’s Z are 16×7 Panasports with Bridgestone S-007a tires in 225/50/16. Our ZCG BIg-Brakes also look great behind the wheels!

 

Interior

 

With the Z back from paint/bodywork we installed the interior, door panels, windows and all new weatherstripping. A complete dash restoration was performed with full HVAC/ducting using a reproduction piece from Vintage Dashes. ZCG has done several Vintage Dashes installations and we thank Ivan Jaramillo for making a cost-effective product for Z cars.

 

Recaro Specialist seats in leather are our favorite upgrade to the S30 interior. Beau enjoys modern creature comforts like Bluetooth, back-up camera, power steering and full sound system:

   

Another upgrade to the interior of an S30 is our ZCG sound deadening package. The result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors. All weatherstripping was replaced:

 

Details

The little things are what we excel at. Below, fuel cap plating with drip gasket, 240Z OEM mirrors and stainless window trim, microphone for hands-free Bluetooth mounted near steering column. Please check the gallery below for more detail shots, there are too many to list in this blog post!

The Transformation

Beau’s 1976 Datsun 280Z before and after:

 

Driving is Believing

ROB: This is a full ZCG-style restoration top to bottom and the best part is that Beau has been Enjoying The Ride. The Z has so many details/features in it and we are just happy to make his dreams come true. He comes back for a 1,000 mile checkup soon… and it’s back on the road again.

 

BEAU: From the exterior, I wanted the car to look as original as possible but I wanted better handling, more power, modern braking and some nice amenities like the back-up camera and power assisted steering. I wanted the car to be as original as possible – so, the engine was restored/upgraded by Rebello, many of the original parts were cleaned and re-plated and I stayed away exterior modifications like fender flares.

 

BEAU: Right now, I’m just enjoying the car. Nearly every weekend I go on rides with my 10 year old daughter and my son and I just attended the Tokyo Calling 3 and had a fantastic time taking turns driving the car and seeing what others have done to their Zs. At some point in the future, I’d like to replace the 3 speed automatic transmission with a more modern transmission.

We loved seeing Beau driving his Z on the Tokyo Calling 3 event hosted by Breakfast Club Rally. He’s attended a few more of their drives as well:

 

BEAU: After the restoration was completed, I met up with the children of the original owner to have them see the car and they were floored by the work. It was great to drive in the car with them and hear their memories of growing up with the car. They were delighted to see the car have a new life with me and my family.

  
More good news…Beau purchased a 2023 Nissan Z to complement his 280Z!

 

Thank you for entrusting us with your S30 Beau it was a pleasure working with you. LONG LIVE THE Z!

At Z Car Garage we love getting Z’s back on the road. Garett is a Bay Area local and visited us for mechanical sorting on his 1972 Datsun 240Z. Our Z Car Garage Big-Brakes, Z Car Garage CV Axles combined with a suspension rebuild improved the chassis. Power comes from a Rebello 3L with our Z Car Garage Heat Shield  and in-house dyno tuning to make it sing.

 

“I first learned about Z Car Garage just searching on the internet to see who works on Z cars exclusively in the Bay Area. Then I started watching videos of  Larry Chen and all the amazing work that Z Car Garage provides and I knew I wanted to go with them for their expertise on my 1972 240z, which I couldn’t just trust any mechanic to work on this beautiful car.”

Before we describe the mechanical work, let’s hear how Garett got in to his Z car…

History

 

Garett’s love for the Z starts at a young age. His Dad purchased this S30 brand new in June of 1972:

“Ever since I laid eyes on that car I wanted it and eventually when I turned 20 years old I bought it off of him and after driving for a while it blew a head gasket. I learned about Rebello racing, located in Pacheco at the time and I put in a fully ported and polished 3 liter with triple-Mikuni carbs. The amazing Mike Yoes lived one town over from me in Crockett, and installed my engine right out of his garage.” 

 

“After a while my Z sat in the side of my parents house for a while due to lack of money to fix other parts. After 6 years I’m slowly reviving her and now she’s back better than ever with a lot of love put in. My goal with the Z was to basically restore it back to original look and functionality with the mechanical upgrades to really enjoy the car to the fullest.”

 

Drivetrain

 

Garett’s Z sports a Rebello 3L engine with 280ZX 5-speed from many years ago. We installed what every triple-carbed L-series needs: a ZCG Heat Shield! Garett has #HS00257.

 

Dyno Tuning

 

Rob dyno tuned the Rebello 3L engine with jetting, A/F and performance in mind. Baseline was 215hp/202tq and it left with 229hp/209tq to the wheels:

 

Enjoy the L-series music in this video of Garett’s Z on the dyno…volume up!

 

Driveline Upgrades

Helping put the power down efficiently is an OS Giken LSD paired with our Z Car Garage CV Axles. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin). More photos in the gallery below:

 

Z Car Garage CV Axles

Garett initially contacted us to have Z Car Garage products installed on his 240Z. Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 200 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

We replaced his existing CV Axles (left) with ZCG units (Right). Garett received set #00426. Also visible are the T3 lower control arms:

 

ZCG Big-Brakes

We are proud to have several of our ZCG products on Garett’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) which have the 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 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.

  

We removed the stock brakes and installed our ZCG Big-Brake kit

At the rear, factory drum brakes were replaced with our ZCG Big-Brakes. OEM Nissan master cylinder and Factory handbrake functionality IS retained! Not only do they perform, they look great behind the 16×7 Panasport wheels!

 

Suspension

 

The front suspension was overhauled with new adj. T/C rods from Techno Toy Tuning, new control arm bushings in OEM control arms, rack bushings, ball joints, outer tie rods, steering rack boots and more.

Old, torn rack boots vs new units and new T/C rods:

 

The rear suspension received new T3 lower control arms and rear wheel bearings.

 

Details

 

Small items that make a difference: we corrected his brake booster issues, fixed the emergency-brake lever  that popped out of its housing and corrected his speedometer:

 

While were in the engine bay we also upgraded to a 280ZX alternator with Motorsport bypass and corrected throttle linkage issues to make the gas pedal feel awesome:

 

Panasport Wheels

 

We installed 16×7 Panasport wheels in our offset allowing 225/50/16 tires (Bridgestone RE-71R). The Z was fully aligned afterwards.

   

Driving is Believing

Garett was happy with the mechanical upgrades and ZCG parts:

“I got the work done over last December. Z Car Garage works so fast and everything was done and ready in about 4 days.  I know there were supply chain issues but after 2 plus years of waiting it was worth the wait. I could really feel the difference when driving in hard turns and how the other wheel grips and really pushes my car through the turns compared to the original open diff. The low drone sound went away as well. The Z Car Garage Big Brake kit works well. I put them to the rest and they do their job. I love the drive and acceleration.”

We enjoyed working with Garett and loved that he’s owned this Z for a long time. He’s also into music, playing in bands in the Bay Area. What’s next for his Z car?

“Future plans include new or aftermarket seats which are comfortable on long rides with no lower back pain, while keeping me planted in my seat and maintaining a time period classic look. New gauges and a dash restoration down the line would be nice as well, but all in due time.”

We’re here to help you when ready, Garett. Long Live The Z!

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 2020 Rally From Home South was held October 1 and we had a wonderful driving experience. Hosted by Driving While Awesome, the one-day event brought interesting cars and their drivers sharing a common passion for enjoying the best driving roads in Northern California. We participated with the Z Car Garage 1970 Datsun 240z and this is our report from the day filled with open roads, seemingly endless stretches of curvy mountain passes and good company.

The ZCG Datsun 240z

 

Rob handed me the keys to “Mrs. Butters”, our 1971 Series 1 240z that serves as the shop demo car and I happily obliged to drive. While this S30 deserves its own feature, here are a few details on the build:

Engine: 3.2L L-series with triple Mikuni 44 carbs and ZCG Heat Sheild
Suspension: Full KW coil-over suspension (ZCG-spec)
Brakes: Z Car Garage Big-Brakes
Drivetrain: Nissan CD009a 6-speed, Z Car Garage CV Axles, OS Giken 4.11 LSD
Wheels: 16×7 Panasport with 225/50/16 Toyo Proxes RA1
Interior: Recaro LXF seats

  

The Z performed admirably without a single problem over the 300+ mile event. This is a testament to thorough rally-prep (thanks ZCG crew) and the wonderfully upgraded suspension/chassis. These modifications offered a great balance of ride compliance and stiffness for the canyons with a seamless transition between rough to smooth surfaces. The ZCG Big-brakes also delivered great feel and zero fade…truly confidence-inspiring. Icing on the cake was the Nissan CD009a 6-speed transmission :

 

This gearbox completely transforms the driving experience in Butters. Gone are the long throws of the close-ratio ZX 5-speed and any feelings of fragility with high-speed shifting. The 6-speed simply clicks-off shifts with minimal effort and the gear spacing is truly a match made in heaven for the L-Series. More details with full testing (weights/dyno etc.) coming soon. Enjoy this video of Ms. Butters and hear that L-series sing!

 

 

Rally Start: San Juan to Coalinga

 

With the recent fires and COVID changing how we live, the typical 3-day format of previous DWA rallies (CRR Rewind 2019) was changed to a one-day event. I really enjoyed it and though a single day sounded appealing I did miss the extra driving and mingling of former events. This year the rally was dubbed Rally From Home South, as the start was very close to the South Bay Area. I joined fellow enthusiast Geoff W in his 1972 BMW 2002 Monday morning to blast down to the starting point in San Juan Bautista, CA.

 

The mini-cars and coffee of rally participants was full of wicked metal, both old and new.  The DWA organizers encouraged us that this isn’t a race, and to enjoy the roads at our own pace. I can’t emphasize enough how great this group of folks is. A good portion are DWA-veteran rally drivers and the positivity was contagious. We were the only Datsun/Nissan represented!

   

Geoff and I grabbed our swag bags and rally maps and hopped into our cars heading South through HWY 25. A few brief stops along the way, at Condon Peak (Ron’s S2000) and oil fields in Coalinga:

 

King City to Fort Ord

 

The next stages leaving King City were a mix of long sweepers with a few technical sections.  Despite the smoky sky and blistering heat we made it to the Green Bridge. Here, Geoff and I took a nice break under some trees. Soon we were joined by Naveed, Brendan, Marcelo and a few others!

 

Carmel Valley Road to Laguna Seca

 

This was my favorite stretch of road on the rally. We enjoyed it so much that we turned around and drove it again, while capturing some video of the cars in action. While Geoff and I were putting in work wrestling our vintage cars, Naveed was comfortably living the dream in the Porsche GT3RS from Abrahim of StealthLabs:

 

It is difficult to describe the driving experience through photos, so please enjoy this video I made!

 

Geoff and I switched cars for a bit. I was really impressed with the 2002’s handling, it’s a gem. The rare Camapagnolo wheels also look incredible with the sticky CR65 tires. We arrived at the entrance to Laguna Seca and it was another car show representing a great feature of DWA rallies: diversity. So many cool cars from all era’s and marques! This was a fun time chatting with fellow rally’ers

   

Our final stop was a relaxed gathering at Fort Ord under a filtered sunset.  A great way to end a day of driving. More picture in the gallery!

 

Thank you DWA!

 

Rally From Home South was a surreal experience. I am still day dreaming about the incredible stretches of roads that we travelled all in one day. For what seems like a brief moment in time we were transported to another world with changing landscapes, smells, sights and sounds.  Big thanks to the crew at Driving While Awesome and old/new friends met during the rally. We are definitely signing up for the next event! Enjoy the picture gallery below and LONG LIVE THE Z!
