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

3.2L-Powered 1971 Datsun 240Z 5-speed Rocketbunny

 

 

 

 

 

Randy Jaffe’s 1971 Datsun 240Z Series 1 S30 started as a project car with paint/bodywork performed by Bryson Richards of Classic Livery. The Z was shipped to us from Georgia for finishing his vision of a wild show/go race car. Inspiration for the Tangerine paint color and Jagermeister livery came from Randy’s obsession with Porsche, and the Max Moritz Racing Porsche 934.

Providing room for the 275/315-width tires and custom Panasport C8 wheels is an authentic Pandem Rocketbunny aero kit. Randy channeled his passion for racing into this build and the chassis is virtually identical to his #46 BRE Datsun 240z, using zinc-plated DP Racing suspension parts. The engine is a dyno-tuned 3.2L L-series running 13:5:1 compression, triple-Mikuni ph44s, a Fujitsubo header and glorious BRE-style exhaust. Running gear includes a close-ratio 5-speed ZX transmission, R180 OS Giken LSD, our ZCG CV Axles and ZCG Big-Brake Kit (race version). Continuing the race car theme is a stripped, body-color interior with Sparco race seats, steering wheel and custom Alcantara custom dash. BRE/vintage details throughout.

Car is is pristine condition with zero chips, scratches or defects. Approx. 400 miles on build. 1st Place Winner Best Datsun 240Z at the Japanese Classic Car Show.

3L-Powered 1970 Datsun 240Z 5-speed Safari Tribute

 

 

 

 

 

Randy’s 1970 Safari Z is a tribute to the original #11 car piloted to victory by Edgar Herrmann and Hans Schuller in the 1971 East African Safari Rally. Nissan campaigned three of these S30s in the rally, finishing 1, 2 and 7th place while handily beating Porsche’s and other marques along the way. This is an early 4/70 production (VIN 03227) Series 1 car and Randy shipped it from Georgia to our shop to prepare it for the “60 Years in 30 Seconds” commercial as part of “The New Nissan” ad campaign starring actress Brie Larson.

The drivetrain includes a new, dyno-tuned 3.0 Rebello street motor using a 10.5:1 head for pump gas, triple-Mikuni ph44 induction (as the original #11 Safari Z ran) complete with Harada intake, velocity stacks, linkages and Z Car Garage Heat Shield covering the Fujitsubo exhaust header. All backed by a new, 1982 280ZX 5 speed transmission and OS Giken 4.11 LSD.

The interior features period touches like navigator’s equipment including 70’s route map, microphone headsets, rally timers and reproduction vintage race seats. Small details remain faithful to the original car inculding functional Works-style side jacking points, rear bumper steps and twin-exit exhaust system. Car was featured by Nissan at SEMA and by Larry Chen in his YouTube video series.

2.8L-Powered 1970 Datsun 240Z 5-speed Bonneville Salt Flat Race Car

  

 

 

 

This 1970 Datsun 240z set the F/GT class record (1976) of 166.037 mph at Bonneville with Nissan USA field engineer Bob Stockman behind the wheel. The car was stored in Nissan warehouses for decades until our client Randy acquired it from Nissan in 2020. The Bonneville Z-car is chassis HLS30-05834, built in June 1970. Never sold to the public, with only ~2300 miles.

The exterior features the “G-nose”, a factory-made, 5-piece kit for the JDM-only Fairlady ZG (HS30-H) and created for Group 4 racing, The stripped interior houses a simple roll bar with integrated headrest. The steering wheel is a rare, “Ura Mach” unit. This leather/aluminum steering wheel was an available option to all S30s from Nissan sports/race, with the stock wheel being wood composite made by Izumi. Though available as optional parts, these seats and steering wheel were removed from a 432R and installed on the F/GT car as delivered from Japan by Nissan!

In 2021 we performed a sympathetic restoration of the Bonneville Salt Flats Z. The original record setting motor prepared by Tom O’Connor and his team at Nissan was not available, so we installed a high-compression L28 built by BRE team member John Caldwell. It features triple-ph44 Mikuni’s with Harada intake, velocity stacks and Z Car Garage Heat Shield. The exhaust system includes a ceramic-coated header and side/rear exit all painted white. The dyno-tuned engine is backed by a low mileage 280zx close-ratio 5-speed with a JWT aluminum flywheel ad HD clutch.  Power is sent through an R180 with 4.11 gearset complete with new bearings and hardware. Original Firestone Bonneville tires, and 15 inch steel wheels that were used during the record setting events are included in sale.

Car was featured by Larry Chen in his YouTube video series, and won the Amelia Award in the 1961-’89 race car class at the 2025 Amelia Island Concours.

Ex-Jim Fitzgerald 1979 Datsun 280ZX Race Car

 

 

 

 

 

This 1979 Datsun 280ZX was raced from 1980 through 1983 by Jim “Fitzy” Fitzgerald, Paul Newman’s close friend and teammate. Fitzy remains the winningest driver in SCCA history and campaigned this 280ZX in C Production as well as IMSA GTU.The car has belonged to Adam Carolla (2009 to 2017), then our client Alex McDowell who raced it the Monterey Motorsports Reunion and many Laguna Seca vintage events from 2018 to 2021.

Z Car Garage refreshed and prepared the ZX for racing in 2018. The drivetrain includes a dry-sump 3.2L Rebello race engine (approx 5 hrs) with triple-Mikuni ph44 carbs on a Nissan Competition intake manifold, Nissan Competition exhaust header with straight pipes into exhaust megaphones, 3.9 OS Giken LSD, ZCG CV Axles and 5 Speed Nissan Comp 2 Transmission. Suspension consists of Koni race shocks, period disc brakes and 16×10 Panasport C8 wheels.

1966 Ford Mustang Fastback R-Style Race Car

 

 

 

 

This 1966 Ford Mustang fastback was built as a B Production race car in 1991 by Historic Race Engineering of Costa Mesa, California and has competed in VARA, SVRA, VDCA, and HSR events since. It is a period-correct homage to the Shelby GT350R, featuring Shelby-style bodywork along with an upgraded suspension and brakes, larger wheels and tires, and safety equipment.

The small-block Ford V8 is backed by a Toploader four-speed manual transmission was purchased from Cobra Automotive. The car was reportedly built to FIA specifications and is currently configured for SVRA Group 6, VDCA Group 6, and HSR Group 3 competition.

John B has been with us for many years. We featured his 1971 Datsun 240Z back in 2013 when he visited Z Car Garage for a mechanical overhaul, dyno tuning and Panasport wheels:

 

In 2020 he returned for our Z Car Garage Big-Brakes and more sorting. Since then he’s been Enjoying the Ride and recently completed his first track day at the world-famous Laguna Seca. Enjoy his track day report and read on for a summary of work we performed over the years.

John’s Track Day at Laguna Seca

 

JOHN: Here’s a report on my Track Day at Laguna Seca on 29 Nov 2025, with some history of my Z cars.

The event was hosted by Turn8 Racing on Saturday 29 Nov. It was my first time, so was a member of the Beginner run group. I brought both of my Z cars but only drove the 1971 240Z on the track. There were many other types of cars in the run group, some new ones like a 911 G3 and a new Ferrari, but there was one other 240Z.

 

The first couple of runs were “lead-follow”, where we followed an actual race driver around the track to learn the proper race-line through the curves. For the remaining runs we were free to attempt to find the race-line on our own, which happened occasionally for me. It’s pretty obvious when I did not have the race-line since I was either in the dirt or was quickly approached by traffic from behind. I found the slower I went the easier it was to find the race-line. The Beginner run group only allowed passing on a couple of the straights (for this event), it was my track during the turns and my chance to learn to find the race-line so I felt it as ok to go slow.

 

Of course, once in the straights, everybody passed me. By “everybody” I mean EVERY car on the track. They may have been going faster, but I was having a blast with my 240Z on the track. My smiles per mile was high.

 

My favorite turn was turn 9, the sweeping left-hander out of the corkscrew. Probably because it’s challenging to judge the brake/coast/accellerate adjustments since the next turn (10) is slower right turn. It’s nice to “have” the whole track during the turns at the Beginner run group to try different approaches. The whole track is great, it’s Laguna Seca man! What fun.

 

I want to go back with my 1977 Lotus Esprit to see if I can beat my lap time in the 240Z. I expect that the Esprit will have faster laps since it seems to accelerate quicker out of turns and is closer to a race car than the Z. I had ZCG inspect the 240Z the week before the event to ensure that the brakes were up-to-snuff. They performed well, as expected since both of my Zs have the Z Car Garage Big-Brakes.

 

ROB: John asked me about doing his first track day in his 240Z. I think the interest came from attending our Vintage Racing Events with his girls, eating snacks and hanging out at the track. I said why not? You’ve got brakes that can handle it and we know the car is safe. We did a tech-inspection on it, made sure everything was good to go and yes, John Bunker drove his S30 on the world famous WeatherTech Raceway also known as Laguna Seca. Good job John keep on loving the Z we can’t wait to work for your girls someday.

The Z Cars

 

ROB: We met John around 2012 and did a bunch of work to his 240Z. He later acquired a 280Z and 280Z 2+2 so his daughters could ride with him. Both of these S30s have our Z Car Garage Big-Brakes. John and I have the same passion for music and he is just exactly why I love my job: he’s passionate and spends time enjoying and driving his Z cars. He also has a vintage Lotus that we’ve done some work on.

 

JOHN: The 240Z is a 1971 model built in Oct 1970. My mom bought it in 1978 and I’ve been driving it since 1980 (45 years, yowza). My siblings and I used to ride in the hatch. (Why a mother of six bought a two-seat sports car is a point of discussion amongst us). It was her daily driver until about 2000 when she started having trouble getting in and out of it. She put about 250K miles on it and replaced the L24 engine with a rebuilt one from a 260Z. I bought it from her in 2005. In 2013 ZCG went through it and made it run as it should. We installed the Big Brake Kit, Panasport wheels, new tires, new headers, exhaust, and a suspension upgrade including Techno Toy T/C rods. It now has about 275K miles on the road and about 40 on the track.

 

The other Z is a 1978 280Z. It was originallly owned by my mom’s neighbor. He traded it to my brother for some custom furniture in 2000. I bought it from my brother, then sold it to my niece, who sold it to her brother. It sat in the driveway of his mother (my sister)’s house for a few years until I bought it from my nephew in 2019 where it went straight to ZCG for a Big Brake Kit, new Panasport wheels, tires, and a suspension upgrade. It has about 195K miles.

 

Both are daily drivers, mostly. I can’t take my two daughters in them (well, not legally), so it’s usually just me in the car going to work. There is a third Z car, a 1976 2+2, intended to take the whole family, but we will not talk about that here. These are multi-generation family cars. The goal is for my girls to continue the Z-car tradition when they get older.

Z Car Garage Big-Brakes

 

In 2020 we installed our ZCG Big-Brakes on John’s 240Z, giving him the ability to brake on a dime, perform well and daily drive. This is the same brake kit as seen on “Mrs. Butters”, our 1971 Series 1 240z shop demo car (above).

 

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 removed John’s stock brakes and installed our ZCG Big-Brake kit. The Z also received suspension parts from Techno Toy Tuning including their adjustable T/C rods.We really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

   

ZCG Big-brakes up front:

  

T3 T/C rods and new brake master cylinder/booster, clutch hydraulics:

 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality retained!
