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!
Happy New Year! Today we kicked off 2022 the right way with a New Year’s drive on a beautiful California day. Our friend Geoff assembled a group of cars and we were pleasantly surprised to see several Z Car Garage clients and friends in attendance! Thank you to everyone that braved the chilly morning temperatures and truly showed that Datsuns Are Driven! Enjoy photos and video from the cruise below.
I drove my 1967.5 Datsun Roadster and it was a cool 36F at 8:30am as I hit the freeway for the meeting point in San Jose. It was so good to see familiar faces and cool cars. Geoff briefed the group and we rolled out 16 cars strong heading up HWY 17 to Bear Creek Rd. Let’s take a look at the group:
Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:
Jose M was happy to join us in his Z. After 8 years, Rob and Jose re-connected at our 2023 Nissan Z Viewing.
Felix’ 1996 Nissan 300ZX Twin Turbo
Felix joined is in his 1996 Z32TT. This 300 will also get an updated feature on zcarblog.com.
Pall’s Nissan Skyline GT-R
Pall’s R32 recently visited ZCG for Haltech ECU and dyno tuning.
Datsun 510s
We had three Datsun 510s in Wagon, 2-door and 4-door models!
Mark’s 1972 Datsun 510
We upgraded Mark’s 510 with our Z Car Garage CV Axles. These CV axles help transmit power to the ground and ensure smoother operation compared to standard half shafts, while eliminating the need for aluminum adapters. Mark got ZCG VV Axle set #320 and he loves them:
Nick’s Datsun 510 Wagon
Z Car Garage’s very own Nick F drove his L-Series powered 510 wagon with SSR mesh wheels.
Dustin’s Datsun 510 4-door
We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. Hagerty produced a video featuring the local Bay Area Datsun couple you can see it HERE. Dustin also installed our Z Car Garage CV Axles himself on his 510!
Our fearless leader Geoff in his Lotus 7 and my Datsun Roadster. Also joing us was William in his (964) 911:
Enjoying The Ride
Bear Creek Rd. up to HWY 9 to the look out was surprisingly traffic-free. At the lookout we could see clear across the Santa Cruz mountains to the coast. A few late-model Porsche’s stopped by.
Enjoy this video of the drive and all cars particiapting:
From the lookout we drove up Skyline (35) and down Alpine Rd. Recent rains have made lush forests:
After a short re-group we took 84 up to Alice’s Restaurant and chatted for a bit. It is always busy here and the eye-candy endless. My J-Tin radar was treated to Mark 3 and 4 Supras, S14 240SX, R35 GT-R, MR2 and DC2 Integra:
This Model A had a hot-rodded 4-cylinder Flathead. It’s a small world and through Geoff we were introduced to the owner, John B. John races a Jaguar Special with CSRG!
Thanks to everyone that came out. We hope you get to the Enjoy The Ride this year, let’s make 2021 amazing. DO IT IN A DATSUN!
It is always great to see friends over the holidays. Gary Savage stopped by Z Car Garage from Florida and shared these photos from his visit, enjoy!

One of the real joys this holiday season is the opportunity to say thank you and wish you the very best for the new year. From all of us at Z Car Garage we thank our friends, family and customers again for another exciting and productive year! Enjoy our 2021 recap and upcoming projects. Please note our holiday closure below:
ZCG will be closed from 12/24/21 and we will re-open for business on 1/3/22.
We had a busy year and though the shop will be closed, we won’t leave you hanging for the holidays. Many zcarblog features have yet to be published like our belated race report from the 2021 Velocity Invitational in addition to client stories.
Before we take a look back at highlights from 2021, here are several exciting projects coming along at the shop:
Jeff and Ryan B’s LS3-powered Z came to us for mechanical sorting. It’s now sporting our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles. Ryan successfully ran the Targa California Rallye in blistering summer heat. He recently got a new set of VOLK TE37V wheels full report soon!
The OMS Pace Car
This is a 1972 Official OMS Pace Car Duplicate. It is at present one of only two known survivors . Fifty were originally produced by Nissan Motors to commemorate the DATSUN 240Z being selected by the Ontario Motor Speedway to Pace the 1972 “U.S.A.C. California 500 Championship”. It really is a small Datsun world, as the official OMS pace car is none other than our very own Joel Anderson #49 IMSA GTU 240Z .
This OMS duplicate belongs to our long time customer and friend Linda. She acquired it from a family in SoCal and tasked ZCG with making it a nice driver. Full report soon but it got loaded up today for its journey to Colorado!
Jim’s 1971 Datsun 240z returned for a Rebello 3.2L with triple-Mikuni carbs on a Harada intake and CD009a 6-speed transmission:
David’s 240Z
Long-time friend and client David attended a track day at Laguna Seca. This Z was built over 15 years ago and sill running strong. We prepped his Z for the track, full report soon!
Dyno Tuning your 350z/370z/Q/G
We have been dyno tuning your late model Nissan/Infiniti sports car daily. Bolt-ons, UPREV tuning. Our customers leave happy with more performance. Call us to schedule an appointment! Here are just a few cars:
Aaron’s Q50:
Randy’s 1970 Safari Tribute Z lived an eventful life this year. It was in Los Angeles to be filmed for Nissan’s commercials and also served as Randy’s ride for cruising around Monterey Car Week. We installed a new engine and made some suspension changes. Though it’s back at home in Georgia it will get a full ZCG-style feature.
One of many Z32s we are working on, Steve’s will get a full report soon:
Highlights from 2021
Even though 2021 was crazy year for all of us we still managed to have fun on and off the track. The shop made some really great progress as well.
Enjoy these highlights from the year and Z you in 2022!
Datsunworks
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. You can read all about it HERE
2021 was a development year for this drivetrain setup. We continue to extract more power and run longevity testing with owner Gary who has the pleasure of living daily with this beast. More updates to come, but for now enjoy the music this KN20 head provides in the video below!

We love to see our parts installed and used on client’s cars. Race car driver and Datsun enthusiast Brad H is running our ZCG CV Axles in this IMSA GTU 240z race car!
Brad is preparing his Z for the next race season and a half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. He installed set #312 with ease, stock half shafts (left) and ZCG CV Axles (right):
“The rear end is a LSD R200 with a 3.70 gear. I’m not really sensitive to the rear gear ratio because of all of the variability I have in the gear box. It’s connected to the rear hubs by Z Car Garage CV axles. I had been looking for options on axles simply because the thought of going into Nascar 4 at Daytona with 50 year old U-Joint technology made me nervous. I heard about Z Car Garage from Randy Jaffe. We are both in Atlanta and I was at his shop one day because he was kind enough to let me borrow a rear diff to carry as a backup to Daytona. While there, he showed me the CV axles and I reached out to Rob to order a set the next day. We have kept a great relationship ever since.”
Check out Brad’s installation of the ZCG CV Axles and see the Z in action in the video below!
Brad’s IMSA 240Z Build
Let’s hear how Brad found and built his 240Z race car:
“The story of my car starts with a poster I had on my wall as a kid of the Bob Sharp Racing GTU Z that was campaigned in 1976. We raced ITS Z cars back in the late 80’s, but I had always said that if the situation presented itself, I would build a tribute to that car. The original was destroyed in ’76 at the Camel GT at Road Atlanta when Sharp blew a tire coming up to the bridge and hit the embankment hard on drivers left. That left a tribute as the only option.”
Brad found a solid chassis that was running as a track day car in Ontario Canada. Peter Skillins had built the car (www.datsunzcars.com) and had done a fantastic job. The cage was done by Blaise Csida (www.bcracecars.com) who is a well respected Trans Am driver/car builder. In addition to a very robust cage, several additional reinforcements were installed like additional shock tower structures and additional stiffening structures on the front frame rails.
“The car was then sent to Burtin Racing (www.burtinracing.com) here in Atlanta for final assembly and installation of the IMSA GTU body kit that John Washington at ZTrix puts together. It’s a great kit that requires minimal modification to the body panels themselves, but the fabricators at Burtin when a bit further by putting together some additional components to support the kit under my application. Specifically was a new nose frame and airbox set up as well as new customer rear fender inner liners. All body panels are removable with 1/4 turn fasteners and the car can be stripped in less than 3 minutes. The Burtin fabricators (Terry and Damon) work daily preparing/maintaining a top tier Trans Am team (Tomy Drissi and Simon Gregg), the work they do is top notch and highly recommended. All along the way the fabricators at Burtin Racing made small suggestions on performance and safety ideas.”
The motor was built by Steve Nelson at Top End Performance in CA (www.racetep.com). It’s an L28 with a 2MM stroke add that runs at 13.1:1 compression.
“It has a race cam and is fed by 3 Mikuni 44PHHs. Steve and team do a great job on the bottom end, but the reason I went with TEP was that they use Slover head porting. Slover has long been one of the best head preparers in the L series motors going back to the origins of L series racing engines. If you’ve ever seen the work they do you would quickly understand why. Steve also recommended running the Electromotive crankfire ignition system. I was hesitant at first, but was sold very quickly when you get to see ease of timing adjustments and the complete elimination of timing slop you get at over 6-7,000 RPM. That was a great call.”
“The gearbox is a Hewland STA wide the came out of one of Burtin Racing’s TA cars. They upgraded to sequential, so Claudio (the team owner and good friend) recommended we install the Hewland behind the L28 because of its reliability and optionality with gear sets. To do so required a custom adapter that the Burtin guys made on the CAD and removal of the existing tunnel. We went with a Quartermaster dual clutch set up that connected to the 28 spline shaft of the Hewland. With this box installed, I have access to no less than 50 gear sets which lets us gear the car for each track we go to. For Road Atlanta, which is my local track, we run a 2.20/1.88/1.44/1.23/1.09 configuration with a 1:1 spur gear.”
Brad enlisted Andrew at Wheelflip (www.wheelflip.com) who was able to find him 2 matching sets of late 70’s BBS centers with the stock 4X114 bolt patter. After taking many measurements they ended up with 2 sets of gold 16X11 fronts (5.5 outers/5.5 inners) and 16X12 rears (6.5 outers/5.5 inners). Brad runs Goodyear Eagle slicks with the 430 compound:
“The car was fully wrapped in the Bob Sharp Racing livery from 1976 by the same folks that wrap the Burtin Racing TA cars, AAA SignCrafters (www.aaasigncrafters.com). Huge thanks to the folks at Harris Decal (www.harrisdecals.com) for putting together all the special decals that were required to get the look correct”
In mid 2021, Brad moved to his own shop in Buford, GA under the operation of BPH Motorcars, LLC. The car is currently maintained by Jason Howe of Howe Custom Fabrication. Jason was a former fabricator at Burtin Racing as well as for the Panoz racing operation and does fantastic custom work. You can follow Brad’s racing efforts on Instagram.

Thanks for your support Brad! We look forward to seeing you on the track for the 2022 race season, LONG LIVE THE Z!
