This is Sean’s 1970 Datsun 240Z featuring our Z Car Garage CV Axles and Z Car Garage Big-Brakes that he had installed in SoCal. Highlights include a Rebello 3.0L, triple-Mikuni induction, Nismo 6-speed transmission and Watanabe wheels. Let’s take a look at how Sean got into Z cars…

 

Sean: This early-production 1970 Datsun 240Z Series 1 was purchased in 2019 from the original owner’s family. The original owner, in the army and stationed in Okinawa at the time, bought the car there brand new in mid-1970. It’s an early-production car with a 4/70 build date, chassis number HLS30-2811, and is one of the early non-EVAP examples. After completing his time overseas, he had the car shipped back to the United States in 1972, where it spent its entire life in Long Beach and has remained in California ever since. The family also included the original 1972 California pink slip with the car, which I thought was incredibly cool. Because of its lifelong California history, while the car does have some minor rust in common areas, it remains a very solid and honest example with excellent bones.

 

The original owner passed away roughly 25 years ago, after which the car sat dormant and untouched. When I acquired it, although largely original, the interior was in rough shape, the engine barely ran, and the car showed clear signs of long-term neglect. Over the years, it had been repainted twice in its lifetime, but I intentionally chose to leave the exterior exactly as it is. The layers of paint, chips, and exposed remnants of the original finish tell the story of the car’s history, and preserving that character became more important to me than restoring it cosmetically..

 

Interior

 

SEAN: While the exterior remains untouched, I painstakingly restored the interior myself back to essentially factory condition, using as many original parts as possible. This build was never intended to be a trailer queen — it was built to be period-correct, with modern underpinnings, driven, and enjoyed. Because of that, a full repaint will probably never happen. I know I’d never be able to keep it perfect, and honestly, I enjoy the car far more this way. I drive it through the canyons nearly every weekend, which is what it was built for...

          

Drivetrain

 

SEAN: Mechanically, the car has been transformed into the driver’s car I always envisioned. It’s powered by a 3.0L Rebello engine, paired with a Nissan S15 Nismo six-speed transmission and a fully rebuilt R200 differential with a Quaife LSD. Supporting modifications include triple Mikuni 44 PHH carbs, Kameari headers, a Fujitsubo Legalis R exhaust system, 123 Ignition, and Koyo radiator:

 

SEAN: The car recently dyno’d at 234 horsepower and 221 lb-ft of torque to the wheels on a Dynojet, which is more than enough for my needs. At this point, the build is pretty much complete Now it’s simply about enjoying the experience and continuing to drive a car that feels incredibly rewarding every time I get behind the wheel.

Z Car Garage Big-Brakes

 

SEAN: The chassis was upgraded with Techno Toy Tuning and Apex components throughout. The Z Car Garage Big-Brake and CV Axle upgrades absolutely transformed the car, and I couldn’t be happier with the results. The car has also been professionally corner-balanced and tuned to my liking.

 

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

SEAN: I’ve always had a love for these cars. I bought my first Datsun 240Z in 1988 for 700 bucks before my senior year of high school and went on to own several more throughout the 1990s before selling my last one in 2001 due to having twin boys, as life understandably shifted priorities, but I hoarded and held onto all my parts, knowing that someday I’d own another one once the kids finally flew the coop..

 

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

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!

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:

Enjoying The Ride

We received some flattering feedback from Mike after the Z was shipped back to him in NC:

MIKE: Hey my friend, I drove the RB25 to Cars and Coffee Saturday morning. Best damn 240 I’ve ever driven. Absolutely love that car. Gonna be my own “Mrs. Buttersworth” Gonna call it “Mrs. Lemonade” in your honor. Great job!!!

Thanks for your support Mike and Long Live The Z!

Tyler has been in Rob’s life since he started working as a head engineer at Stoptech. He is behind Research and Development of our Z Car Garage Big-Brakes, and we couldn’t have done it without his drive and passion. Our collaboration with Tyler always results in excellence, so when he mentioned bringing his Porsche 914 up from SoCal we happily obliged to work on it.

 

TYLER: “Rob Fuller/ZCG and I have known each other for a while now through my Engineering work at StopTech. We developed the Z Car Garage Big-Brakes for small wheels together. During the development of the BBK, Rob Fuller the man himself would constantly call me and leave hilarious singing voicemails, mostly him belting out hair-metal versus then saying “CALL ME BACK!”. We really hit it off during this time and grew to have a deep respect for one another.”

 

“I think we were able to really nail the final product after lots of tweaking and testing. ZCG was stoked with the BBK and I was stoked to work with such an amazing shop and crew. This project has always been a highlight for me. So when Rob asked me about my 914 and heard about my troubles with it he instantly offered to help out. This was definitely an offer I couldn’t refuse, so I brought my 914 to the shop.”

 

History

 

Before we go into the work ZCG performed let’s hear from Tyler about his 914…

TYLER:  “My first car was a 1973 914 2.0 my Dad, brothers, and I bought for $1200 ~25 years ago. We fixed it up and started to race it together, we still have it and plan to get back to racing it one day soon. Ever since then I wanted another 914 for myself. I just like the fact that 914s are mid engined, air cooled, and has a horizontally opposed engine, all of the coolest Racing Porsches are in this configuration. Also the 914 is three more than a 911, so there you go. When I saw the 914 on a Tucson AZ Craigslist post in 2015 I knew I had to snag it. The car was an old PCA/POC race car that raced in the 70s and 80s in AZ. I knew the car was a diamond in the rough even though it wasn’t running and had many problems to address.”

 

“I ended up buying it from someone in Tucson AZ for $3000 and towed it back home. Ever since then I have been fixing it up and getting it running well enough to enjoy classic rallies and some track days. I have been sort of converting it back into more of a streetable car but still keeping it raw and sort of rough that still gives you a feeling of a race car. My favorite thing to do is go for a drive down PCH with my wife and my dog squeezed in between us and stop at the beach for a walk and swim or rip the snot out of it on the track.”

Chassis and engine details on the 914 below:

Brakes

 

Custom designed StopTech big brake system. Front 2pc 282 x 28 rotors with STR42 calipers and rear 2pc 290 x 22 rotors STR42. Pads are StopTech SR33 front and SR33 rear with custom SS lines. Brakes are lighter weight than stock and with more thermal capacity!

 

Suspension

Race Bushings, Koni shocks,,22mm front sway bar, 150lb springs, 911 hubs, 5 lug conversion, 7×15″ Fuchs front wheels, 8×15″ Fuchs rear wheels, Toyo Proxes Ra1 225×50

Chassis and Safety

Roll Bar, 5 point belts, Frame reinforcements, door jam and chassis stiffening bars, dront fenders are rolled rear are fully flared, battery relocated to the front.

Engine & Transmission

 

2.0 Liter european pistons and sleeves 8.6 to 1 compression, Engine balanced and heads machined, Dual IDF44 Webbers, Mild race cam, High capacity oil pump with deep pickup, Dual rear mounted oil coolers, 4 into 1 exhaust with Supertrap muffler. 5 speed with shortened 3rd,4th, and 5th gears, Short shifter, OS Giken LSD. “Only 914 in the US to have an OS Giken LSD installed that I know of!”

The Z Car Garage Touch

 

ROB: “Tyler had his car dyno-tuned previously but it wasn’t running well. We like to make cars better, so we performed suspension work, adjusted the valves, sorted out his carb linkage, ignition system and made it awesome. Upon arrival it had a really bad front windshield install, so we replaced it and the stainless trim. New valve cover gaskets, cap and rotor, re-did the throttle-linkage return springs, serviced the air filter. Basically went through the Porsche like we do with our Z-car clients so he could enjoy driving it again.”

 

Dyno Tuning

With carb work, timing and linkage adjustments the 914 made 110hp/115tq at the wheels, gains of 18hp/15tq from baseline. Tyler was really happy with the results:

 

TYLER: “Rob gave my car some serious balls…I don’t have the official numbers of the final dyno run but the car feels like it’s been hitting the gym HARD. Engine runs super smooth, sounds like a completely different beast, starts without issue, is really responsive, runs a lot cooler, and has an overall boost in power! It has increased the enjoyment factor 100%.”

Enjoy this video of the dyno run and Tyler driving home from the shop down to SoCal:

After checking the suspension we mounted fresh Toyo RA1 tires followed by a full alignment in-house. Tyler was ready for the road trip home.

 

If it ain’t the Z-car, please let it be the P-Car!

 

Tyler shared a few photos from his roadtrip down to SoCal, catch his adventures on Instagram. Thank you Tyler for letting us work on your 914 and continued support for our Z Car Garage Big-Brakes. Stoptech or Don’t Stop At All!

TYLER: “ZCG is one of the top shops I ever had the pleasure of working with. As a customer, the experience was equally great. The team is really driven, they have expertise to really handle tricky stuff and strive for perfection with everything they do. I knew my 914 was in the best of hands even though ZCG specializes in Z-cars, their talent easily translated into P-cars.”
