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

  

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:

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’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:

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.

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.

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!

Frank’s 1978 Datsun 280Z features our Z Car Garage Big-Brakes, full suspension refresh, 240Z bumper conversion and Panasport wheels. Before we dive into the work let’s see how Frank found the right Z car…

 

FRANK: My best friend (shout out to Mike Springer) in high school had a 77 Datsun 280Z and that is where my love affair began. I’ve owned a 260 and 510 back in the day and always told myself I’d have a really nice Z one day. Just before covid, I saw NASSTY Z (show below), driving around south San Jose and got a chance to ask the owner (James) where he had his work done. He mentioned Z Car Garage. Note to self.

 

When covid hit I ventured out on my own and found a 240Z to start my project. Took it to Z Car Garage and got the worst news ever. Turns out the bones were no good and ended up losing money and the fire to keep going. About 2 years later the fire came back. I hit up Rob and told him I needed his help. We talked about what I wanted and we picked a car that Rob had in his possession for many years. A one owner, blue 1978 280Z with 58k original miles. Rob was waiting for the right person to come along…and that was me.

 

ROB: A few years ago I bought a low-mile 1978 Datsun 280Z from the original owner. I worked on this car since I was in my 20s and it sat dormant. Got it up and running and just kinda hung out here waiting for a friend, and that friend was Frank Moody. Let’s backup. I met Frank in 2021 when he bought a 240Z that was in bad shape. Even though we had not met before I told him straight up this isn’t the Z for you. Let’s move on and wait for the right one. Frank bought the 280Z and we started working on his vision.

 

Maybe it was fate, as Frank saw this 280Z featured in one of Larry Chen’s Autofocus episodes back in 2020. The video highlighted ZCG client Trevor’s 1978 Datsun 280Z , and soon-to-be Frank’s 280Z is examined as a great canvas to begin one’s journey as an alternative to the 240Z. Let’s dive in to the work performed to help Frank achieve his vision for the Z…

Suspension

 

The suspension was refreshed with a full Techno Toy Tuning coil-over package done in ZCG black finish, with Koni dampeners , T3 control arms, tension rods, ball joints, rack bushings and new F/R wheel bearings.

 

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.

Panasport Wheels

Complementing the new Big-Brakes on Frank’s Z are Panasport wheels! We installed 16×7 Panasports and Falken Azenis tires in 225/50/16. The Z was fully aligned, and you can also see the ZCG exhaust system below:
