Family Z: John’s 1971 Datsun 240Z

Filed under: 240z,280Z,Featured Cars and Projects,Parts,Performance

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.

Mike’s RB25DET-powered 1971 Datsun 240Z

Filed under: 240z,Parts,Skyline
by Alvin G @ 2:40 pm on December 23, 2025

 

Mike R sent us his 1971 Datsun 240Z from North Carolina for mechanical sorting, Z Car Garage-style. Our Z Car Garage CV AxlesZ 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 240zTrevor’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:

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 (sorry this is NLA). 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. Mike’s RB25 240Z ZCG Big-Brake installation below:

   
Our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake function. 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.

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:

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 250 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

ZCG CV Axles installed on Mike’s 240Z shown below with more pictures in the gallery:

 
 

KW x Z Car Garage Coil-over Suspension

 

Our Z Car Garage KW V3 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.

The little things are what we excel at. We handled some weatherstripping around the cabin and installed a SpeedHut speedometer box. More photos in the gallery 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!

Frank and Patty’s 1975 Datsun 280Z

Filed under: 280Z,Parts,Performance
by Alvin G @ 2:40 pm on October 15, 2025

 

Frank’s 1975 Datsun 280Z features our Z Car Garage Big-Brakes, Z Car Garage CV Axles, full suspension refresh, 240Z bumper conversion and Panasport wheels. Before we dive into the work let’s see how Frank and Patty found their Z car…

 

FRANK: Our 1975 280z was affectionately nicknamed “Charlie” in 1978 when we became the third owners of the car. I was 22 at the time and my parents had promised to help me buy my 1st car when I finish college. My girlfriend Patty accompanied me down to San Jose to look at the car and test drive but more accurately she had to do the test drive of the manual transmission because I only knew how to drive an automatic transmission. I think I made up the story that the 280z was for my “little sister!” From that moment on that Datsun Z became part of our lives. A short while later we drove “Charlie” on a nice day trip to Monterey where I proposed and I even wrote Patty a note promising that if I ever screw up our marriage, the Z is hers. Talk about a unique prenup!

 

Anyway “Charlie” has always been with us often as a daily driver to school, work or sometimes to Sears Point to watch that actor race for Bob Sharp. Servicing was usually done at Z Doctor in Richmond or Hayes Auto in the city but as the years went by and these places closed we started to rely on neighborhood service station mechanics.

 

Fast forward 37 years later, approaching retirement and a big move to San Diego one of my work colleagues who races Miatas asked me if I had ever heard of a fellow vintage racer Rob Fuller who does wonders on Z’s out of his shop Z Car Garage. After exchanging a few photos, Rob agreed to take on a new project. Luckiest day in “Charlie’s” life!


ROB: Frank was a doctor at a SF hospital and his colleague (Matt) was racing Spec Miata as a newbie while I was racing full-time SCCA in 2022, no longer taking any work in.  So through a racing connection I was able to take in their car. We performed extensive work on Charlie: injectors, header, ZCG exhaust system, all hydraulics, clutch, Z Car Garage Big-Brakes, heater core, 240Z bumpers, full suspension and 16×7 Panasports.

Suspension

 

The suspension was refreshed with Techno Toy Tuning parts done in ZCG black finish. KYB strut inserts with Eibach lowering kit, T3 control arms, tension rods, urethane bump stops, rack bushings, control arm bushings, ball joints , f/r wheel bearings, ST sway bars, mustache bar bushings…everything was powdercoated or zinc plated.

Before/After:

 

More chassis photos in the gallery below!

 

Z Car Garage Big-Brakes

We are proud to have several of our ZCG products on Frank’s 280Z. 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 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

 
 

Frank’s 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!

 
 

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 250 CV axle kits on customer cars and we are stoked with all of the positive feedback. Frank’s ZCG CV Axles set #0047 shown below:

 
 

New motor mounts, tranny and diff mount. The differential was resealed:

 

Panasport Wheels

 

Complementing the new Big-Brakes on Frank’s Z are Panasport wheels! We installed 16×7 Panasports with 225/50/16 tires and performed an alignment:

 

Engine

 

We knew the car would be stopping and handling better than before, so next up was the engine bay. Once up and running we found the head gasket weeping. We replaced the head gasket, did the front timing chain set and refreshed the top end:

 

A Koyo race aluminum radiator with upper and lower hoses was installed to keep temperatures in check. The heater core was refurbished:

 

Beyond cooling and fuel system work, the engine was largely untouched to maintain factory reliability. The intake manifold and all associated plumbing was cleaned up and injectors replaced. We replaced intake and exhaust manifold gaskets with factory Nissan parts with a few ZCG tricks like our exhaust nut and exhaust studs.

 

New alternator before/after:

 

New evap canister:

 

The exhaust manifold was replaced with a 6-into-1 header and EGR kit leading to our ZCG exhaust system with stainless resonator and slash-cut tip.

 

Engine bay Before/After:

S30 World Fuel Tank

We decided to start fresh with a new S30 World fuel tank.  Great product from owners Gustav Oplasnik and Chris Visscher, Z enthusiasts/restorers.  All the vapor hoses in the back were replaced and hatch weatherstripping to eliminate fuel smell in the cabin:

 

Interior

 

Recaro Specialist seats in leather are our favorite upgrade to the S30 interior:

 

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 on Frank’s 280Z:

 

240Z Bumpers

Frank wanted to clean up the exterior lines and replaced the large, factory 5-mph bumpers with chrome bumpers from a 240Z. We installed aftermarket F/R bumpers after our man William closed up all the holes and finished the paint work. Enjoy the before/after photos with more in the gallery below.

Enjoying The Ride

 
 

We shipped the Z back to Frank and Patty in their new home down in San Diego. They were super stoked with the ZCG work performed and immediately began driving the car. Their first car show was The Main Street America car show in July put on by the Corvette Club of San Diego. Over 400 cars with a Datsun category.

 

FRANK: Rob and ZCG basically made our 280Z the awesomest most fun to drive ever. The list of replacements and improvements is too long to list but basically incredible upgrades with ZCG BBK, suspension rebuild with KYB struts springs, new bushings, ball joints tie rods control rods sway bar etc… and ZCG 2.5 exhaust system, ZCG CV axles, all new hoses, Koyo Race radiator with belts and so much more! Cosmetically a new head turner with 240Z style bumpers, beautiful bigger wheels with sticky tires and Recaro seats that are the envy. Again so many upgrades a long list but needed and appreciated. “Charlie” is faster, handles better, brakes with authority and what a tone!

Patty and I will always be grateful to Rob for his expertise, Z enthusiasm, honesty and did I mention sweet singing voice. A true pleasure to work with.

 

Thanks for your support Frank and Patty. Long Live The Z!

Christopher’s beautiful S30 and his ZCG Big-Brake installation:

 
 

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!
