Mike R sent us his 1971 Datsun 240Z from North Carolina for mechanical sorting, Z Car Garage-style. Our Z Car Garage CV Axles, Z Car Garage Big-Brakes, Z Car Garage KW V3 coil-overs and CD009a Six-Speed transmission transformed this 919 Sunshine Yellow S30.

 

ROB: We’ve been very fortunate to work with many clients from the East Coast. One of them is Mike Rogers, you might remember a few years back we did a really early 1970 Datsun 240Z for him and it turned out wonderful:

 

He purchased an RB25-powered 240Z and called us asking ‘hey do you think we could kinda do what you guys typically do to these cars?’ and I said absolutely. The Z was shipped to San Jose, Ca and we installed our ZCG Big-Brakes (Stoptech), our private label KW V3 coil-over setup and ZCG CV Axles. We just did as much as possible to correct things with the install of his RB25 and it was a fun project.

Drivetrain

 

ROB: The RB25DET engine swap was already installed by a previous owner. We left the engine bay aesthetics as is and focused on getting it running well. The goal was to make it as close to a Z Car Garage-style RBZ chassis-wise with decent power. We did not turn it up, as Mike is not about big power with this one. 

 

CD009a Six Speed Transmission

A game changer for this RB Z car was to replace the RB five-speed and install a new CD009a Six-speed speed. It works so well together and this transmission is definitely our go-to choice whether you have a powerful or just-for-fun street car S30. We really enjoying doing these swaps behind L-series engines. You might remember our first application of Austin Hoke’s custom 6-speed adapter kit on the OS Giken TC24B1Z-powered 240z, Trevor’s 280Z and Frank’s 240Z:

  

Using the 6-speed conversion kit from Hoke Performance we installed a new CD009a transmission from the 2003-2008 Z33 behind the RB25DET in Mike’s 240Z:

  

Here is the brand-new transmission from Nissan being unboxed. Hard to tell from the interior once it is installed:

   

Driveline Upgrades

We built Mike an R180 rear diff with 3.54 OS Giken LSD, a perfect upgrade for anyone doing spirited driving. All done in-house with new bearings/hardware by our very own Joshua Corwin:

 

Dyno Tuning

Ron dyno tuned the Z, making 261hp/227tq at the wheels. Enjoy the RB25 sounds in the video below!

 Z Car Garage Big-Brakes

   

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

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.

Panasport Wheels

 

Our ZCG Big-Brakes also look great behind the new 16×7  Panasport wheels in our offset allowing us to run 225/50/16 tires. These were a welcome replacement for the Rota wheels on the car. The Z was fully aligned afterwards:

  

Suspension

 

Mike’s chassis was treated to a full suspension rebuild with new parts 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. Mike 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. Before/after show below:

This is Matthew’s 1973 Datsun 240Z featuring our Z Car Garage KW Suspension. He has kept the car mostly original aside from chassis and drivetrain upgrades including a triple-carb’d L-Series, Watanabe wheels and Recaro seats. Let’s take a look at how Matthew got into Z cars…

 

Matt is from Calgary, AB and we know him through his father, Rob from many years ago. Our good friend Herbert was selling his original paint, 87k-mile 240Z and Rob noticed it on zcarblog.com leading to his acquisition.

MATT: My Z car story is a family affair that began at a young age. Growing up, my parents both owned Z32 300ZX convertibles — which, incidentally, is how our connection with Z Car Garage began in 2004 when Rob and the team at Z Car Garage did a pre-purchase inspection on one of the Z32 Convertibles before being imported to Canada. We were active in a local Z car club in Calgary, Alberta, attending events with the 300ZX. At the time, the 350Z was new and exciting, and I even had a poster of one on my bedroom wall.

 

But to truly understand our story, it’s important to go back even further. When my dad was a teenager working at a local gas station, he fell in love with an orange 240Z with a white interior that often came through. He was 18 at the time and never forgot that car. Fast forward to 2009, when Rob from Z Car Garage called and told my dad he had to buy a 1973 240Z that had just been featured on ZcarBlog.  My Dad flew down to Seattle, WA to pick up the car and drove it back to Calgary, AB. I was 15 then, and I vividly remember working on the car with my dad. We replaced the dash with an original, uncracked one, fixed a minor oil pack leak, and made lasting memories at local car shows and events.

 

When I turned 18, my dad gifted me half-ownership of the Z. Unexpected circumstances forced us to sell the car in early 2012. By then, though, I had fully caught the Z car bug. I spent the next year or so searching high and low across classified ads in the U.S. and Canada, but nothing quite compared to our Z. On a whim, I posted a “wanted” ad on our local classifieds, using the most recent photo I had of the car. Then, in March 2014, I received a message that simply said: “Hello, I own your old car,”…followed by a phone number. We exchanged a few emails and calls, and they even sent me a photo of the car’s current condition (below, March 2014).

 

On April 5, 2014, I picked up the car and drove it straight to my dad’s house. He didn’t know I had bought it back. I drove past the house, and he spotted it from inside. I don’t think I had even parked before he was out the door, beaming with excitement. Not only had I gotten back into a 240Z — I had brought home our 240Z, the same one we had built memories with years earlier.

 

From 2014 onward, the car remained largely untouched. Matt was finishing university and starting his career, and while he drove it when weather permitted, the Z mostly stayed as it was. Behind the scenes, he was always dreaming of how he’d eventually build it — period-correct modifications, all reversible, in case they ever wanted to return the car to stock.

 

In 2021, he began collecting parts for the build. He started with a second set of suspension components, which allowed him to send the spindles and hubs out for the KW coilover conversion and have other parts powder-coated or zinc-plated.

KW x Z Car Garage Coil-over Suspension

 

Our Z Car Garage KW Suspension is available in limited quantities. These coil-overs offer game-changing performance suitable for street, track and daily-driving for your S30 Datsun Z car. View the suspension installed on Sung Kang’s RB26DETT-powered Datsun 240Z, Larry Chen’s SR20DET-Powered Datsun 240Z, James’ turbocharged L-series powered Datsun 240Z, Mrs. Butters, our Series 1 shop 240z and more client cars HERE. For more information on ordering and pricing please contact RobATzcargarage.com.

   

MATT: I first came across KW’s Classic segment on their Instagram page in 2021, which featured the 240Z platform. A few years later, I reached out to KW and learned that Z Car Garage would be the exclusive dealer for the kit. Given my family’s long-standing history with Z Car Garage, it was an easy decision to contact Rob and place an order.

 

The installation was straightforward, though slightly more involved than on a modern car due to the need to install bearings into the hubs. I also opted for the KW adjustable top hats, as I planned to run 16×8 +0 Watanabe wheels and wanted to avoid rolling the fenders in order to preserve the car’s originality.
The first drive revealed a night-and-day difference compared to the stock suspension—firm, yet compliant enough to maintain comfort for street driving. Although Z Car Garage ships the KWs with a recommended out-of-the-box setup, we ended up softening the settings slightly to better suit the rougher roads in Calgary, Alberta, which are no match for the smoother roads in California.

 

In the corners, the car feels extremely planted, with excellent turn-in and feedback. With my current setup, the grip provided by the suspension and tires far exceeds the car’s power output, making it an absolute joy to drive and toss around in corners. Before installing the KWs, I drove more conservatively, hesitant to push the car too hard. Now, with the upgraded suspension, my confidence—especially in corners and at higher speeds—has grown significantly, allowing me to truly enjoy the full potential of my Z car.

 

It took a couple of years to gather everything, but with the help of a good friend — who also happens to own the local performance shop, VEX Performance in Calgary — the build finally started coming together in July 2023. We removed the old suspension and replaced it with freshly powder-coated components and, of course, the KW suspension. The engine bay was cleaned and prepped for the new Fujitsubo exhaust and triple Weber setup.

 

But the moment it all came together was when the car was lowered onto the ground, sitting on its new Watanabe wheels. That’s when it hit me — a rush of emotion. The same Z my dad bought in 2009, the one I brought home in 2014, had finally become the car I’d dreamed of for years.

 

Thanks for your support Matt! We love that you are building and enjoying your dream Z car! What’s next?

MATT: As of 2025, the Z is exactly how I envisioned it. I take it to local Cars and Coffee events, car shows, and the occasional late-night meet. As for future plans — they’re still up in the air. I’ve considered going EFI, or maybe even an OS Giken TC24 build someday. But for now, I plan to Enjoy the Ride.

This is Christopher’s 1975 Datsun 280Z featuring our Z Car Garage CV Axles, Z Car Garage Big-Brakes and ZCG KW coil-over suspension! He performed a meticulous restoration himself with highlights including an ITB EFI-fed L-Series, CD009 6-speed transmission and Watanabe wheels. Let’s take a look at how Christopher got into Z cars…

 

CHRISTOPHER:  The previous owner of the Z lived less than a mile from our house. I noticed it in his garage one day on the way in to work and immediately went by that afternoon to ask him about it. It was bought new in his family and given to him by his Uncle. It hadn’t ran in over five years and he was hoping to get it back running. I asked him almost every other week for about a year to keep me in mi d if he ever decided to sell it. He eventually moved for work and was forced to sell the car…

 

…My wife was the first to tell me and I was pushing the car to our house that afternoon! I got the car running after a few months and drove it stock for a year or two. After moving down south and the car being exposed to high humidity, I decided to restore the car and take care of the body before things got out of hand. What began as a tear down to have the car repainted, turned into a full nut and bolt restoration that overall took just under six years to complete.

 

Drivetrain

 

Christopher’s fanatic attention to detail really shines in the super-sanitary engine bay. The stock L28 uses Jenvey individual throttle-body fuel injection (MegaSquirt ecu) with parts from Datsunspirit and ProTunerZ. He made a mount for the IAT sensor, installed @fuelinjectorclinic injectors, @robsperformancemotorsport fuel rail, and @radiumengineering bits (fuel pressure regulator, gauge, and two petcock drain valves for the catch cans). More photos in the gallery below!

 

CHRISTOPHER: The goal of the build was to highlight and improve what was already great about the car. I wanted the appearance, weight and simplicity of a 240 with the drivability, performance, and rigidity of the 280. I was inspired by GT3s and similarly was seeking to build a light weight, naturally aspirated car with ITBs and and a quality exhaust. The car now weighs 2400 pounds and I wanted to ensure only quality items were installed (OEM or better).

 

Below: At Moore Performance dialing in the ITBs. Chris plans to re-visit the dyno to squeeze more power with a different CAS sensor.

 

The exhaust includes a Z-story header and custom piping fabricated by Tyler Dorsey. Below, also visible are T3 coil-overs, LCAs, and Z Car Garage CV Axles:

  

Z Car Garage Big-Brakes

  

CHRISTOPHER: I heard about ZCG from various Datsun Forums before I purchased the car. Rob and ZCG were known for their passion with the S30 and the research and development that went into every product offered. I chose ZCG for the lower control arms, brakes, suspension, and coil overs because I wanted a cohesive setup that was developed in a way that ensured every component worked in harmony with each other and improved the S30’s driving characteristics, not change it.

  

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

 

  

CHRISTOPHER: Early on I considered more outrageous options that were popular within the community. But after researching those companies, and the reviews of their products further, it became clear that was not the direction I preferred to take. A lot were over engineered and under tested, over complicated, or unnecessary. Ultimately, I chose ZCG after numerous conversations with Rob where he spent time breaking down his own personal opinion and the shop’s research to highlight where other options may over engineer products to the detriment of the car or may not unlock the full potential of the chassis. I liked that he was honest with what he thought was worth upgrading and what wasn’t necessary. It was obvious he cared and wasn’t out for just a profit. He lives these cars.

 

Big-Brake Kits Available For DIY Install!

Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Christopher’s beautiful S30 and his ZCG Big-Brake installation:

 

CHRISTOPHER: The installation was a breeze. Uniquely for this project, Rob and I talked early on (almost five years ago) about testing ZCG’s ability to develop and deliver products beyond the west coast. We began this venture as a means to begin testing the various elements of that process logistically. For this, Rob also wanted to demonstrate how ZCG was capable at recommending, assembling, and shipping complete components to the point that it removed much of the work and guessing from the consumer. Rob’s hope was to prove that if someone wanted the complete setup (engineered and proven by ZCG over years of experience), a customer could essentially order the catalogue and receive a complete solution delivered to their front step. That’s exactly what happened with this.

 

Our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake function. Chris successfully installed the BBK on his Z and they look great behind the 16×8 (zero offset) Watanabe wheels with 225/45/16 Toyo tires. Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! 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.

   

CHRISTOPHER: The car feels planted like never before. Our family also has a fully restored 73 240 that is an excellent OEM example. Where that car feels stable and drives well, there’s no denying the age of its component and it drives like a seventies sports car.  The 280 feels like a modern sports car and inspires confidence. The brake pedal communicates exceptionally well and the balance of the calipers bring the z down from speed a rate well beyond most cars today. The light weight of the S30 and the size of the ZCG big brakes is an unreal combo!

 

Z Car Garage CV Axles and KW Suspension

  

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. Christopher’s ZCG CV Axle set, #0457 installed by himself:

 

Detailed shots, note how clean his work is!

CHRISTOPHER: Not only does ZCG already provide extensive installation guidance (70 plus pages of instructions for the brakes alone that cover everything from torque specs to bleeding procedures), but, for this, he assembled and shipped each corner fully assembled (spindle, wheel bearings, coil over, and camber plates). I was able to install the whole assembly into the strut tower, the lower control arms, and attach the brake lines and the corner was complete! Having this work done by Rob not only saved me time, but also gave me the piece of mind that these critical pieces of the chassis were done right and by someone with decades of experience. From there it was installing the ZCG CV Axles and I was then off to the remainder of the build.

  

KW x Z Car Garage Coil-over Suspension

 

Christopher installed our KW V3 suspension, complementing the ZCG Big-Brakes and CV Axles nicely. Details on our ZCG KW V3 coil-overs will be covered in a dedicated blogpost coming soon.

 

CHRISTOPHER: The KW V3s offered by ZCG are the most valuable investment I’ve made in the car (and I’ve replaced nearly every bolt on the car at this point lol). Nothing has affected the performance and drive of the car as drastically as the coil overs. The Z is smooth on the highway and is able to carry momentum through corners like never before. I can’t wait to get it out on the track this spring. Couldn’t recommend them enough. Wether it’s the brakes or the suspension, ZCG has formed relationships with the partners that matter and have a proven track record in the auto industry. There’s nothing else like it period.

 

Interior

 

Chris’ phenomenal work extends to the interior where original surfaces were refurbished or replaced with OEM parts.

CHRISTOPHER: I chose to put the original luggage riser vinyl back in as I really like the original small diamond pattern better than the newer options. Also installed the rear quarter panels I bought off @sportzwerks and refurbished which never came with the car. Feels good to be bringing it back better than it was. Pretty cool to see the refinished dash frame from @vintagedashes  in the car as well as the dash cowl with @speedhut gps puck installed. The 6-speed shift knob is from @thedavemason:

 

Enjoying The Ride

After a long journey Christopher is driving his Z! Follow his build on Instagram and see it in action in the video below, volume up!

 

CHRISTOPHER: Moving forward I plan on getting the z out to meets and on the road! It’s going to be driven! I found a lot of the suppliers that helped with Nissan’s heritage program when the 350Z was released, and took the time to create what I hoped to be a quality build that maintained the character of the S30s with components that not only perform but will last another 50 years. The result isn’t blistering speed but a visceral driving experience in a truly timeless car.

 

Thanks for your support Christopher we love that you are Enjoying The Ride and Long Live The Z! More photos in the gallery below.
