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.

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)

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..
