We love to see our parts installed and used on client’s cars. Race car driver and restoration specialist Jim Froula of Racecraft is running our ZCG CV Axles in this Nissan IMSA GTU 300ZX race car!
Jim installed CV Axle set #269:
The George Alderman Z31
Over a 49-year competitive career, George Alderman was one of America’s most successful sports car drivers, racing in Sports Car Club of America (SCCA) and International Motor Sports Association (IMSA) events.
In the 60’s and 70’s George would race a variety of cars. He won the IMSA Baby Grand championship in 1971 in a Datsun 510 and in the 80’s he drove Z cars in the Camel GT series. His Z31 would run both turbo and NA classes for IMSA.
Out of 70 starts he had 50 top-tens, 27 top-fives, and 5 wins, all while successfully running his Datsun/Nissan franchise. (Below) a 1988 promotional photo of the Z31 in front of Alderman Nissan, in V6 IMSA GTU class trim. Find more history on this Z as documented on Alderman Machine.
Restoration at Racecraft
Jim and the RacecraftNW crew restored the George Alderman 300ZX. As usual, Froula’s painstaking efforts and diligence result in a faithful restoration. Original frame (left) and restored with chassis parts:

Thanks for your support Jim! We are excited to see the Z31 back on on the track.
Z Car Garage CV Axles
Over 150 sets of our ZCG CV Axles are installed in client’s cars all over the world. For more information please visit our detailed post our HERE. Below are just a few examples of race cars running out CV Axles:
Race car driver and restoration specialist Jim Froula of Racecraft is running ZCG axles in several of his cars:
Set #246 – installed May 2018 on the “Harry Stewart #52” Datsun 510:
Set #247 – installed April 2018 on the 260z
Set #248 – installed on Adam Carolla’s “Greg Sorrentino #90” Datsun 510.
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!
Jay M purchased a set of Panasport Wheels from Z Car Garage and recently shared his Z story with us. We are an authorized Panasport dealer and have limited sets available for fitment on your S30 Z car. Before we show you how a set of these 16×7 wheels look on almost every Z color imaginable, let’s hear about Jay’s 240Z…
“The car was from California and made its way to Gainesville FL and was put in storage.I had been looking for a good 240 and this one was taken by the owner to a shop owned by a friend of a friend.The guy wanted to get it running and sell it. That triggered a phone call to me while on a anniversary trip with my wife to Italy, we were living in St Augustine Florida at the time. My buddy sent me some pics and a quick video and he grabbed the car for me. It was all there and very little rust. I had not really considered a Blue one, much less one with white interior.”
The car was restored by Jay and 3 friends minus paint and the head work in his 2 car garage over 3 years. Jay has met so many people in the Z community and learned much about Z cars:
Beautiful engine bay with new engine:
Check out the before/after on the interior…great work Jay and friends!
Jay recalls how he found ZCG and eventually purchased a set of Panasports from us:
“I found the on Z Car Garage videos on YouTube very early on which led me to your website. I went to Daytona to see Randy Jaffe’s #46 BRE 240z car run and left just before John rolled it. I met Rob at the Amelia Concours earlier this year and bought a set of Panasports from the shop. I also have become friends and an Insurance client of Jim Frederick in Lutz Florida who I believe has the finest collection of low VIN original Z’s in the World! Jim has also helped me with parts and advice on this build. I am hoping Larry Chen will make it down to film Jim’s collection.”
The Panasports do look fantastic on this #115 Metallic Blue 240Z. Thank you for your support Jay, glad you are Enjoying The Ride!

It really makes our day to see a client still enjoying their Z years later after visiting Z Car Garage. Last weekend we saw Michael D’s 1972 Datsun 240Z at the 34th Annual Z Car Convention (ZCON) in Colorado Springs, and it reminded us how we’ve worked with him since 2007. Let’s take a closer look at this Nissan RB25DET-powered S30 featuring our Z Car Garage Big-Brakes, Z Car Garage CV Axles, full suspension and Panasport C8 wheels.

Go Green Inspiration
In 2005, Rob Fuller performed an RB25DET engine swap into his 1970 240Z, affectionately named Go Georgia Z (GO GA Z = Go Green Georgia Z). The RB is a turbocharged inline-6 engine from the Nissan Skyline (R33) GTS-T in Japan, requiring new drivetrain mounts and supporting modifications to work in the S30 chassis. Once completed, Rob drove his Z all over California, attending several long distance car shows like Motorsport Auto in SoCal and the All-Datsun Meet at Mt. Shasta.
Rob’s RB-swapped Go Green Z gained notoriety and around 2007 is where our relationship with Michael began. He wanted ZCG to do an RB25DET swap similar to Rob’s in to his super clean ’72 240Z:

As we know it’s always been tough to keep up with demand at ZCG. Mike is a great guy and kept offering us his business but Rob wasn’t ready to take on the project. Instead, we focused on preparing his car to handle the RB swap. Driveline upgrades included a ZCG-prepped 4.38 R180 LSD (since replaced with R200 3.55 Quaife LSD), restored hydraulic/brake lines and our ZCG Big-Brakes and CV Axles.
After the RB swap was completed in 2013 at another shop, Michael returned to Z Car Garage to sort a few more items. We did not like how the fuel system wasso it was redone by us. We also sold him our custom ZCG (Z31) motor mounts and tunnel bracket reposition for the OEM RB25 OEM transmission.
A few specs on Michael’s current setup: RB25DET rebuilt with RB26/Neo/N1 parts, BorgWarner EFR 7670 turbo, GTR coil set, Bocsh 1000cc injectors, TIAL 50mm BOV, McKinney Pan and Radiator, Wiring Specialites Harness and a LINK Ngtr+ EMS. With 525whp/480ft-lbs, the suspension and brakes were upgraded. We installed a full Ground Control coil-over suspension (remember this was in 2008) and Michael reports great performance still:
“In regards to the performance of the suspension upgrades, coil-overs, Tokico struts/shocks I was considering T3 and Arizona Z control arm suspension replacements. My suspension performs so well with the stock A-frames etc that it didn’t make any sense to change them. I would add, without spoilers my 240z stays very grounded at 130 mph and I know what I am talking about after having owned a ’14 R35 GTR for 7 years.”
Z Car Garage Big-Brakes and CV Axles
To cope with the power of the RB25DET, Michael has our ZCG Big-Brake kit. Not to be confused with our current Z Car Garage Big-Brakes (for small wheels), this Big-Brake kit was our initial setup from over a decade ago. This 328mm sized kit requires 17″ diameter wheels and the massive ST-42 calipers are finished in bright red. We actually did all the R&D in-house for this setup…using a 280ZX master cylinder and our own mounting brackets.
Michael also got a set of our custom Panasport Racing C8 wheels. These 3 piece, 17×9 wheels allowed fitment of a 255/40/17 tire under stock fender flares.
When ZCG was starting to build a series of RB-powered S30s, Rob brought in a pallet of C8 wheels destined for the builds. Michael wanted a set so we hooked him up with a silver spoke finish. They look great on his Z:
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 130 CV axle kits on customer cars and we are stoked with all of the positive feedback.
We built Michael a set of CV Axles, shown below:
Interior
Michael is proud of the interior on the Z, keeping it aesthetically close to stock with updated materials and comfort in mind. A Restomod A/C unit keeps things cool. A very special thanks to Luis at Vargas Auto Upholstery:
“Sewed in centers of original seats, Auto Meter digital speedo and tach to modified to look original in original housings, the dash which is impossible was done with requirement to minimize stitches and never cross a stitch, stereo housing was built to match the faceplate of original, has remote electric windows and locks, power steering, hands free phone, android auto for maps, and seats that hold you in while providing comfort for 8+ hour drives.”
Enjoying the Ride
Michael contacted Rob in 2003, just after he purchased his 60k-orignal mile 1972 Z to get the upgrades started. He’s driven it since 2004. Here is what it looked like when he picked it up, and a current photo:
Michael’s goal for the build, aptly named “TRBUTEZ”…
“It is called TRBUTEZ.: A tribute (act, statement, or gift that is intended to show gratitude, respect, or admiration) to the many under $3k starving student Z’s I owned that carried me through life with unconditional loyalty, performance, and dependable reliability. This one is for you. Thank you! My goal is to upgrade the build of the car for an even better personal experience while maintaining the respect this car deserves through preservation of every original detail possible.”
We were stoked to see Michael and his Z at the ZCON event on Colorado Springs. After all these years he’s still Enjoying The Ride!
When you think it couldn’t get better…he won (4) awards!
-1st Place People’s Choice S30
-2nd Place Modified 240Z
-Overall Most Votes (People’s Choice)
-Best Interior (ZCCA Judged Car Show Comp)
Thank you to ZCON organizer Christopher Karl and Meghan Fuller for the show photos! More in the gallery below.
Michael is a super nice guy and we are happy that he’s loving his Z Car Garage parts on the TRBUTEZ. Thank you for your support Michael and Long Live The Z!
Z Car Garage is excited to collaborate with Datsunworks and develop their brilliant KN20 dual-overhead cam (DOHC) cylinder head designed for the Nissan inline-6 L-Series engine.
Datsunworks founder Derek Minetti is the pioneer behind the KN20 DOHC cylinder head. This is a custom (very limited production), 6-cylinder head derived from Honda’s venerable K-series 4-cylinder engine. The KN20 offers superior head flow rates combined with modern valvetrain components to effectively transform your L-series single-overhead cam into a high-revving, dual-overhead cam engine. The power potential is impressive.
Gary’s Datsun 240Z
There are ten KN20 heads in the wild with only three installed and currently running in cars. Z Car Garage has two KN20 cylinder heads. This KN20 is serial #SN10 and it has been installed into our long-time client Gary’s Datsun 240Z, affectionately named the “Behemoth”. ZCG is always exploring the boundaries of powertrains and Gary’s Z has seen a few engines including an RB30DET, OS Giken TC24 and now the Datsunworks.
Here are few details on the powertrain setup for this Z:
-Rebello 3.1L Engine
-KN20 Cylinder head SN10 (but the performance level goes to 11)
-Induction type: Jenvey ITB EFI with Injector Dynamics injectors
-Engine management: Haltech Elite 750
-Header: Equal-length, custom fabricated by RacecraftNW
Pictures of the initial engine installation, with more in the gallery:
For further information on the KN20 cylinder head we urge you to visit the Datsunworks blog: Datsunworks Blog
Performance
We are still in the tuning phase so Gary’s car is on a comfortable (conservative) setting. With the Datsunworks head it made 350hp/248tq at the wheels on 91 octane:
Even in a testing stage it is absolutely thrilling to drive. Gary’s car is a full ZCG-style restoration so it has the chassis to harness the power. The sound it makes is a sonorous tone only the K-series derived KN20 head creates…with a gnarly exhaust note to match. The ITB induction also provides a healthy wail…it’s a sensory overload and revs seem to climb endlessly.
To illustrate the Datsunworks experience we captured some video of what it is like to drive around town…the 6-speed and EFI really allow this car to be docile, especially when cruising on the freeway and at part throttle. Drop a gear and its becomes a wild animal. Not going to lie…it gave me goosebumps both as a passenger and spectator.
Watch the video complete with multiple dyno passes, street acceleration and fly-bys. VOLUME UP!
Potential
Z Car Garage is stoked to be a part of the Datsunworks KN20 development. It is a clever design that pushes the envelope for L-Series engines. Sharing this experience is also part of the fun so we anticipate having a KN20 setup in a dedicated shop 240Z for clients to test drive and further evaluate. Although each application is different, we envision offering a bolt-in setup for your six-cylinder L-Series engine. The power potential is tremendous with the KN20…both NA and forced induction. We thank Derek at Datsunworks for giving us the opportunity to work with this innovative product.
Stay tune for more updates and LONG LIVE THE (TWIN CAM) Z!
