Our Z Car Garage Big Brakes have been winning over Z-car enthusiasts locally and globally. Kim recently purchased a set for his 1970 Datsun 240Z and performed the installation himself at home in Norway. Before we go into his Big-Brake experience let’s hear his Z-story…
Like many enthusiasts, Kim started with a Miata…
“After owning a modified Miata for several years it was time for another project car. I still have the Miata, but that is more for track use now. I was not actively looking for a 240z, but I came across my Z car on a Norwegian sales site. I went to have a look and the car was in good shape, and the price was so low that I just had to buy it. It was repainted in 2005. The paint job was ok, but not perfect. All interior panels, dash and seats were re-trimmed in leather.”
Modifications include Tokico dampers with Ground Control coil-overs and a Nissan 6-speed CD009a transmission using the Hoke Performance kit. Kim was heading to the track and eventually installed a Datsun Spirit 3.1L engine with Jenvey ITB EFI, ported head and custom exhaust. Yes, that’s Kim’s Z on the Nurburging!
You can see the dyno run and acceleration in Kim’s Z in the video below:
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. We can ship worldwide and each kit contains everything needed with a comprehensive (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Enjoy these pictures of Kim’s beautiful Series 1 S30 and his ZCG Big-Brake installation:
As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake. Kim successfully installed the BBK on his Z, and they also look great behind the Work Equip 03 wheels and newly installed fender flares:
“I had a brake kit from Silver Mine Motors and used those for several years. With the new engine and higher HP numbers I really needed a brake upgrade. StopTech from Z Car Gar Garage was the way to go. The installation was quite easy. I did have some questions, and I got answers really fast. They feel awesome.”
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.
What’s in store for Kim’s Z?
“I take everything as they come, and find a new upgrade I like to try from time to time. Well, the goal is to have a car that works every year and I can modify during the winter. All lights are upgraded to LED from Classic Car Leds. AC from Vintage Air, upgrading the engine wiring harness, and consider some wider tires to fill the arches a bit more.”
Thanks for your support Kim we love that you are Enjoying The Ride and Long Live The Z! More photos in the gallery below

We love to see owners installing our Z Car Garage CV Axles on their vintage Nissans and Datsuns. Julio added this 1972 Skyline to his collection and had the team at KaiserKars replace the old CVs with our ZCG CV Axles. You may have seen the Hakosuka at at events in the SoCal area and we are proud to be part of it!
We met Julio last year at the Japanese Classic Car Show where his Skyline was on display in the Hagerty booth. He pleasantly informed us that he was running ZCG CV Axles and we are happy to report that the team at KaiserKars installed them with ease at their facility in Los Alamitos, Ca:
“Our in-house technician said the installation process was very straightforward and simple, basically just a bolt on/bolt off slid right in and bolted each axle to the differential and it was finished. It went as smooth as it could go.”
The team at KaiserKars sent us a few installation pictures of the ZCG CV Axles replacing the old CVs. They shared their experience:
“We were recommended the upgraded CV Axles by a friend of ours that pointed us to Rob. The Skyline came with some rear differential knocking/popping issues, the upgrade fixed the problem. We eventually got in contact with Rob himself and he asked us a few things in regards to what was currently on the car. We think they were a kit by the previous owner but they were completely shot and beyond rebuilding.”
Skyline Dreams
The Hakosuka Skyline is undeniably a JDM icon. We asked Julio about his history with Japanese classics:
“I have been a car geek all my life, but as all guys my age, Fast and Furious, Gone in 60 Seconds, Motorweek and the Saturday/Sunday cable shows were the culprits for my love of all cars. But once I watched Hot Version/Option, and Initial D anime I was smitten by JDM cars and culture, I longed to ride in a GTR, drift an AE86 and own all the unicorn cars I grew to idolize. So far the hunt is on and I seem to be collecting them like others collect Hotwheels. The Hakosuka has been a love affair for me as I regret selling my last one in a bad deal but this one makes up for that bad memory and I could not be happier with its stance, power and aura.”
The Hako features some of our favorite parts like the Rebello 3.2L with Jenvey ITB induction:
In addition to the upgraded ZCG CV Axles the Hako also has an R200 LSD diff, 5-speed transmission, 16″ Watanabe R-Type wheels (8.5/9.5), Rubber Soul stainless exhaust system and T3 suspension. Outside, the body is VW Limestone Grey Metallic with carbon fiber flares, GT-Kai badging and re-finished bumpers in eggshell black. More pictures in the gallery below!
Thank you for your support Julio, it was great meeting you at JCCS! Also, thank you to KaiserKars we look forward to working with you! Please read below for more information on our ZCG CV Axles:
ZCG CV Axles
Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. These are 100% bolt-in replacing your half-shafts and does not use aluminum adapters commonly found in aftermarket units. We have over 150+ CV axle kits on customer cars and we are stoked with all of the positive feedback.
For years we have used aftermarket CV axles that utilize an aluminum adapter prone to loosening up over time. Despite efforts to keep things tight (Loctite, hardware changes) we had to keep an eye on them. We developed a better solution that eliminates the need for aluminum adapters and remains 100% bolt-in like a factory half-shaft.
Designed and manufactured locally with KAD Models, the ZCG CV axle kit works in both R180 and R200 configurations.
These are the beefiest CV axles on the market. They have been tested on the track by our vintage racing customers and also in high hp* street cars (powershifting, clutch dumps, etc.). Each axle has a serial # for peace of mind:
The CV axle kit is available now from ZCG for 1595.00 + freight and they come with everything you need to install on your car. Contact us at 408-452-0350 or send Rob an e-mail rob@zcargarage.com to purchase. Installation is just like doing a half-shaft: there is even a marking that shows you where to line up bolts and special hardware:
The ZCG CV Axles in action
The video below demonstrates the “looseness” associated with aftermarket CV axles that use adapters compared to the ZCG axles without adapters. Several customer race/street cars running our CV axles are also shown. Enjoy!
Enjoy this video made by our client Hazel. She installed our ZCG CV Axles on her Hazel’s 1970 Datsun 240Z
Over 150 sets of our ZCG CV Axles are installed in client’s cars all over the world:
Last Friday we made some glorious L-Series music with two of our client’s Datsun 240Z cars. Gary’s Datsun 240Z, affectionately named the “Behemoth” has accumulated some mileage on the Datsunworks KN20 cylinder head and the dyno confirmed the same power level.
Khang’s 1973 Datsun 240Z was completed in October and he returned with 1,000 miles on the 3.2L L-Series. We adjusted the valves and double-checked power levels.
Happy to see both builds healthy and confirm power output. Enjoy the music from the both L-Series engines, sporting Jenvey ITB EFI managed by Haltech 750 Elite ECUs backed by the CD009a Six-Speed transmission. LONG LIVE THE Z!
Khang D is from Modesto and we first met him in 2012 when he visited Z Car Garage with a green 1975 Datsun 280z. We serviced the car, fixed several items and he enjoyed it for a few years before selling. In 2017, Khang purchased this white 1973 240z from our client Brent B, and returned to ZCG for full suspension upgrades including Z Car Garage Big-Brakes, new OEM mirrors, Panasport wheels and a complete tuneup.
It wasn’t long before Khang came back to ZCG with a request for more power to match the excellent chassis improvements. Let’s take a closer look at this fantastic daily driver+canyon carver showcasing our Z Car Garage CV Axles, Z Car Garage Heat Shield, Jenvey ITB fuel injection, CD009 Six-speed transmission and more.
Suspension
In September 2017 we overhauled the suspension. The Z received coil-overs from Techno Toy Tuning including T/C rods and rear control arms. The entire front suspension was re-done with new bushings, wheel bearings, rack bushings, steering coupler, etc.
Struts, OEM T/C rods replaced with coil-overs:
T3 Rear lower control arms replace OEM units:
ZCG Big-Brakes
“WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car” -Glenn
As fellow 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 master cylinder change or additional proportioning valve/adjustments, etc. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) 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:
Khang’s S30 got the full 4-wheel brake kit with new OEM Master Cylinder:
We also installed the fully functioning parking brake that works with factory linkage/handle:
Khang loves the ZCG Big-Brakes:
“They are a must have and definitely allows the bigger power. Kind of spoiled actually. I’ve recently checked out another 240z and drove it and then hit the brakes and forgot that they were stock and almost ran through a stop sign.”
Engine Bay Services
Khang’s engine bay was painted black so we took this opportunity to paint it body color and perform re-installing the new engine. As usual William worked his magic to apply the white paint while we zinc’d or powdercoated all parts in the engine bay. The before/after is dramatic, no doubt from the new engine discussed below!
New hydraulic lines/plumbing and wiring harness with general cleanup made this engine bay pop:
Engine
After a year of enjoyment Khang desired more power. We installed a Rebello 3.2L engine with upgraded cam, Harada intake and Jenvey fuel injection. The old SU-fed L-series was removed:
We knew the car would be stopping and handling better than before, so we installed a Moroso oil pan and Koyo aluminum radiator to keep temperatures in check. We are using Pacesetter 3 into 2 header ( to clear six-speed) leading to our ZCG exhaust system with stainless resonator and slash-cut tip.
Jenvey Fuel Injection
We are huge fans of modern fuel injection on the L-series for it ease of operation, excellent hot/cold start behavior, tuning abilities and all-around driver-friendliness. Khang’s 3.2L engine uses an individual throttle-body induction setup from Jenvey. We have used this setup on several builds, including Scott’s 260Z with stellar results.
In-progress shots of the throttle body wiring. We mounted the ignition coil on the firewall to minimize clutter. The valve cover was also changed.
The fuel injection system is run by a Haltech Elite 750. The ECU was mounted in the passenger side footwell:
Topping the ITBs off are custom, merged mesh air filters. The sound from the Jenvey EFI is intoxicating. More pictures in the photo gallery!
Fueling mods to support fuel injection including in-tank fuel pump. The tank was pulled and boiled out/refurbished before adding EFI:
Dyno Tuning
Rob dyno tuned the 3.2L via Haltech. Baseline was 129hp/131tq with the old engine and with Rob’s tuning the 3.2L made 264hp/231tq at the wheels. Watch the dyno run and listen to those Jenvey ITBs scream in the video below!
Beyond performance, Khang is very happy with the Jenvey EFI:
“Best thing I can say is I don’t plan to ever go back to a carb setup again. Knowing that it’ll turn on every time and can be on the road for prolong periods of time without feeling like I need a gas mask on. Carbs were tolerable when I was younger but now a days I like the comfort features of EFI.
Driveline Upgrades
We built Khang an R180 rear diff with 4.11 OS Giken LSD, a perfect upgrade for anyone doing spirited driving. All built in-house with new bearings/hardware by our very own Joshua Corwin:
The clutch hydraulics were replaced to work with new aluminum flywheel/JWT HD clutch combo:
Six Speed Transmission
Next on the update list, we were really excited to install a Nissan 350z 6-speed manual transmission behind the L-series in Khang’s Z. You read that right! S30 owners can now bolt-in this robust, 6-speed manual behind their L-series engine! 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 in Khang’s 240Z:
Here is the brand-new transmission from Nissan being unboxed:
The kit necessitated exhaust header changes and after testing a variety of headers we found the Pacesetter 3-2 unit provided enough clearance. Serial 9 provided the shifter relocation assembly and we are really happy with its performance. Also shown is the aluminum driveshaft.
It fits! More installation pictures in the gallery.
It’s a very discreet look from the cockpit…until you feel the amazingly direct and precise feel of the CD009a!
Khang is in love with the six-speed, we are as well:
“The CD009 Gives the Z such a more modern feel but still plenty of fun at the same time. Retains the rawness but then put it into 6th gear and it cruises like a modern day car. Love the shift knob.”
Enjoy this video of the Z in action with dyno runs, engine and exhaust revs, freeway cruising and acceleration:
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 140 CV axle kits on customer cars and we are stoked with all of the positive feedback.
Stock half shafts (L) and ZCG units:
ZCG CV Axles installed on Khang’s 240Z shown below with more pictures in the gallery:
Panasport Wheels
We are an authorized Panasport dealer and lover. Khang’s meshies were replaced with 16×7 Panasports and 225/50/16 Yokohama S-drive tires followed by a full alignment:
Details
We sorted out little things for Khang that make a huge improvement in Enjoying The Ride. One item we are particularly proud of is this custom, OEM-like shift knob displaying a 6-speed shift pattern. Khang is one of the first customers (other than the Behemoth and Butters) to receive this cool shift knob that emulates the factory 4-speed shift pattern and font:
The speedo and tach are functional with a GPS box and tach adapter:
The interior was treated to a new set of Recaro Specialist seats and our ZCG sound deadening program to eliminate that “tinny” sound.
More small details like replacing all coolant and fuel hoses, breather, new battery and cables:
Driving is Believing
When Khang picked up car earlier this year, he was blown away:
“I’ve had several Z’s over the years. I had a green ’75 280z for about 10 years throughout college and had it worked on by Rob at one point. Sold the car and then just missed it too much and literally bought my current 73 240z about 6 months later in May of 26, 2017 as shown in the picture when I went to pick it up. I knew from my previous experience with Z Car Garage that I wanted Rob to build this new one for me.”
Thank you Khang for allowing us to build you a 50 year old supercar. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!
