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:

Dear Zcarblog readers, it’s been a busy year and we are catching up on blog posts, so please enjoy our belated race report from November 2021.
WE LOVE RACING! On November 11-14 we attended the Velocity Invitational at Weathertech Raceway Laguna Seca. Z Car Garage had a blast racing and supporting several client’s IMSA GTU Z cars running in Group 7A (1966-1977 IMSA GT). This vintage racing event was just as fun for spectators with a friendly, immersive vibe. Enjoy our report from the weekend with photos and in-car video of the action.

Z Car Garage IMSA Race Car Support!
If you missed our earlier post, we prepared and supported three IMSA race cars for the Velocity Invitational (VI). Here’s a quick review:
We supported our client Randy Jaffe who recently acquired the Transcendental Racing Datsun 240Z. This famous 1976 IMSA-GTU Championship-winning 240z will be driven by ex-driver Brad Frisselle’s son, Brian Frisselle. Randy recently had the Z re-painted by William with correct graphics and hand-applied livery by the Real Ralph.
#93 Different Drummer Racing Datsun 260Z
Race car driver, restorer and Datsun Historian Glenn Chiou raced his Ex-Greg Sorrentino IMSA 260Z. Glenn built and prepared this race car by himself, ZCG simply dyno-tuned it prior to race week.
Ready for some L-series music from these historic race cars on the dyno? Check out the video below and turn those speakers up!
We also prepared our client Kelvin Tse’s Porsche 911 RSR, because if it’s not the Z-car, it’s the P-car!
Epic Racing With Group 7
Photo by Kristina Cilia
Group 7’s IMSA GT and FIA race cars (1966 and 1977) was dominated by big-power Porsche 911 RSRs with a few BMS CSLs and 4 S30 Datsuns. Speaking of powerful Porsche’s, the organizers did not allow turbocharged cars to run so we thought an NA motor race would make things interesting. Read more about Group 7 here with driver Jeff Francis in Larry Oka’s 1970 Ex-Glemik IMSA Datsun 240Z (#54):
Friday’s qualifying race was eventful. Rob and Brian Frisselle were doing well and putting down some great lap times. Unfortunately, a Porsche oiled down the track between turns 4 and 5 and both Z cars skidded off the track. They recovered under their own power but the Frisselle Z sustained minor body damage from hitting the tire barrier. Good news: Glenn, Jeff and John Murray avoided the mess and Rob Fuller qualified on Pole Position!
Racing in to the Night
Saturday’s Group 7 would start at dusk, a rare exhibition for both drivers and spectators. I zipped up to my favorite vantage point at Turn 6 to catch the sunset. Auxillary lights were placed at each apex and few cars had headlights of their own to navigate the evening’s race. It was magical to watch. Here is Rob Fuller re-capping his sessions from the #49 Joel Anderson IMSA GTU 240Z:
“We had a great first session, made some adjustments to the cars and clicked-off good times. The qualifier was pretty scary as I lost control from a Porsche’s oil spill but I made it out ok. Brian Frisselle is an ex-IMSA professional driver and he safely negotiated the oil slick, avoiding a potentially severe impact with the sitting Porsche and softly hitting the tire barrier. I was surprised to make Pole-Position. Saturday’s evening race was intense. Though I started on Pole, by Turn 2 the Porsche gapped me 3-4 car lengths…
…We were racing our Datsuns with skilled drivers like Ned Bacon, Alan Terpins, and Martin Lauber in their multi-million $ Porsches. I was able to hold on to 2nd place, trying hard to reel Ned in but caution struck again, another Porsche had oiled down the track between Turn 5-6. Now its really dark and I’m trying to stay with Ned then I see these lights coming up hard on me and I know it’s Terpins. Tried to defend but he got around me. Honored to be amongst these guys who never let up. We finished the race in 3rd place.”
Enjoy this video we made highlighting the Group 7 races with in-car, Turn 6 and Goodwood livestream footage mixed in. Volume up!
You can see full, in-car footage from Rob in the#49 Joel Anderson IMSA 240Z over on his YouTube Channel, check out the Qualifying and Saturday Evening sessions. Here is Rob recapping the Sunday race from Group 7:
“Final race was midday with plenty of sunshine. Frisselle started 4th. Three lead Porsches took off, while Brian and I battled for P4. He then got around me and we both enjoyed the magic of driving our IMSA cars. Drivers around me were in expensive machines giving it 100%. Really happy to see 4 Datsuns in top 10 places. Honorable mention to John Murray (narrow body 260Z), Glenn Chiou did a really good job (Greg Sorrentino IMSA 260Z) and Jeff Francis (Ex-Glenn Klemik IMSA Z).“
Joel Would Be Proud
You might recall the story behind this special, 1972 IMSA GTU 240z as it was owned, built and raced in the 70’s by none other than Joel Anderson. ZCG restored #49 back to its former glory and it debuted at RMMR 2014. John Morton would drive #49 at RMMR 2015. Rob Fuller would drive #49 for the first time at the RMMR 2018. Joel was present at all of those events but sadly passed away March 2021 and we miss him dearly.
“This was unbelievable…driving the Z without Joel around was so emotional. Thinking about the fact that all of the vintage race support and seat time we have is all because we met Joel. He taught us how to be racers. His memory was shared by us all at the race.”
Privateer Spirit

Our friend and Datsun Historian Glenn Chiou raced his Ex-Greg Sorrentino IMSA 260Z. It’s worth noting that not unlike privateers of the period, Glenn builds his Z cars, maintains and manages his racing efforts himself. Not an easy task so we applaud his work ethic.
A Fan-Friendly Race Event
Photo by Kevin Ehrlich
Formerly known as the Sonoma Speed Festival (2019), the Velocity Invitational re-imagined the vintage race experience with a Goodwood-inspired vibe. One of the best experiences for spectators is the paddock and organizers made access to drivers and their machines seamless. Fans could get up close and personal with race cars without the typical ropes or 45-foot RVs in the way. It was a dream come true for me to share vintage racing with my family, they loved it!
The hot pit area where all run groups stage before heading out to the track is an amazing place to be. Typically, access is only granted to pit crews and media. At the Velocity Invitational however, organizers staged a “false grid” where any spectator could walk amongst the race cars. Our family loved the artificial turf and hay bale seating lining the grid:
Though the fresh format was immediately enjoyable for spectators, it did come as a surprise to drivers and race teams. Rob’s initial reaction was met with eventual praise:
“Upon arrival to ‘Seca we knew this was going to be a different kind of event. All race cars were displayed together under white tents in the paddock for a Goodwood-like experience. It allowed spectators to see all cars within each race group but it was challenging for the team as our tools and support vehicles are usually near us. Initially we were intimidated but got the hang of it with just our essentials. The layout encouraged interaction and it was super fun to meet other racers, new folks and see old friends. Kudos to the organizers for doing something new and absolutely knocking it out of the park!”
Enjoy this video we made showcasing the sights and sounds of the Velocity Invitational. Rob Fuller gets interviewed by the Goodwood Livestream just before the evening race, and I included the lineup from my favorite vintage race group (other than IMSA), the Trans Am cars!
If you want to see action from the event in its entirety, check out Goodwood’s live streaming coverage Day one and Day Two.
Paddock Finds
At each corner there was something special in the paddock to see like exotics, Muscle Cars, personal sports cars and even Ragtime racers. The paddock never disappoints. Here’s a few of my favorites, more in the gallery! Where else can you see a brace of McLaren Speedtails, Lamborghini Mirua, Mercedes Benz 300 SLR and Lotus Cortina in one place!
Exotics abound with Bugatti and McLaren hypercars:
Really excited to spot this Datsun 240Z in the car corral…it is Z Car Garage client Matt K. Full report soon on this pretty Z car that features our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!
We have more photos in the gallery below. ZCG would like to thank the following photographers for sending us photos from the event, you can click on their name to see their photo albums or Instagram handles: Kristina Cilia, Larry Chen, Pall Kornmayer, Todd Lapin, PnutProductions and Paul and Ann Devor, enjoy!

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!
Our client Jas D listed his 1991 Aztec Red 300ZX Twin Turbo for auction on Bring a Trailer. You can view the auction HERE. Below is our blog feature of the Z, enjoy and happy bidding on this stunning Z32.
To appreciate the 1991 Aztec Red 300ZX Twin Turbo pictured above we must tell you a story of love, heartbreak, persistance and ultimately satisfaction. Z Car Garage client Jas D has been with us since 2014 when we helped build his 1990 Nissan 300ZX Twin Turbo. This Super White, 44k original-mile example was treated with all the ZCG touches that make a Z32TT go from wonderful to extraordinary. We dubbed it the “Z Masterpiece” (see more here) as it embodied the total package: Power. Handling. Braking. Aesthetics:
Jas totally Enjoyed The Ride in this Z, adding 28k thrilling miles with ZCG maintaining it over the years:
“My brother and I have been ZCG customers for almost a decade. I met Rob when I called about getting a PPI on what became Z Masterpiece. At the time, a Super White manual came up on AutoTrader (I LOVE Super White-OMG). It was a low-mile, one-owner, meticulously-maintained time-capsule. Rob actually said WOW after the PPI, and we worked with ZCG over a couple years on a few iterations until we got Z Masterpiece. That car was perfect! My dream Z; I loved driving that car EVERYWHERE! It is probably my favorite car of all time!”
Unfortunately, in 2016 the Z was stolen.
“On October 29, 2016, Z Masterpiece was stolen. We cried, we laughed, we got angry, we sulked for a couple months, forgot about it, and then my dad found the car driving into SF on January 25, 2017. The car had clearly been driven like it was stolen. But, believe it or not, all the expensive components were still on there. We sent it to Rob right away, and he helped us turn Z Masterpiece into the Red Devil Z (which I purchased on April 20, 2017 with 66,XXX miles).”
From Z Masterpiece to Red Devil
Persistance paid off, and Jas found a really clean Aztec Red ’91 Z32TT with only 66k miles. All of the upgrades from the Super White, Z Masterpiece were transferred over:
“Rob pulled the motor from the Super White, re-did all the seals/gaskets, and then put the driveline back together into the red Z32TT. Coincidentally, both cars and engines had 66,XXX miles when this was done in summer 2017.”
Let’s take a look at the modifications that turn the already stellar Nissan 300ZX Twin Turbo into a superb, balanced sports car.
Engine
Though bone-stock with an amazing 44k miles on the clock it needed some attention. We went through the hydraulics and performed full 60k-mile services.
Jas wanted to improve power and handling and we happily obliged with a comprehensive list of upgrades this year. Starting with the drivetrain, the original transmission was replaced with a brand new(!) unit from Nissan:
The clutch had seen better days so we replaced it with a JWT unit including their heavy duty aluminum flywheel:
A JWT ecu w/boost jets manages uprated NISMO 740cc injectors and the Selin dual MAF. Improved breathing comes from Ash-SPEC inlet piping and dual JWT pop chargers:
On the exhaust side, restrictive original downpipes were replaced with these beautiful Specialty Z 3″ downpipes. Note the divorced wastegate piping:
Following the new downpipes are more parts from SPZ including 3″ mid-pipes and a cat-back exhaust system to replace the OEM setup:
OEM vs SPZ:
More upgrades. We installed 4.08 Leader gears, Ash-SPEC Massive SMICs, 2.5 IC tubing, and SPZ Hi-5 upgraded clutch. The BDE low-profile Z32 motor mounts are a smart alternative to OEM that allows more clearance larger for intakes:
Rob recently dyno-tuned the red Z, making 353hp/353tq to the wheels on 91 octane:
Stoptech Big-Brakes
With all of the speed parts installed next we tackled chassis improvements. Let’s begin with brakes followed by suspension:
We love Stoptech’s products and use them on our own vehicles. Z32s are relatively heavy and with higher hp the stock caliper/rotors can be taxed quite easily. Jas took it up a notch and ordered a Stoptech 4-wheel Big-Brake Kit for his beloved Z. Shown above is the ST40 caliper (front) squeezing 332 mm rotors and at the rear are ST22s on 328mm rotors.
The installation:
Yes, they are pretty but also very functional. Speaking of aesthetics (that are functional, too), the new calipers are nicely framed between the spokes of these sweet VOLK TE37SL wheels, finished in bronze and sized 18×9.5/10.5 in high-pad offset with center caps. We like your taste, Jas. The lightweight TE’s were wrapped in Yokohama tires:
Suspension
The suspension was gone through completely with all new parts. KW V3s are our favorite coil-over setup, replacing the Stance coil-overs that the Super White Z had. Stillen sway bars are also shown:
Stock vs KW V3s installed front:
Rear:
Every little nook and cranny of the suspension was handled. New SPL tension rods, upper front control arms, new rear wheel bearings and HICAS removal/eliminator:
T/C rods, Stillen sway bar, we also replaced the rack bushings:
The Z looks great!
The interior is in great condition as well:
Jas and his brother love the Z. Thanks for letting us be a part of your journey!
“The Red Devil Z is vicious and so fun to drive. It is the quintessential 1990s Japanese sports car – red – gold wheels – TTs – exhaust. It goes fast. It stops fast. It turns fast. Z32TTs are the BEST! We love and respect Rob and the team at ZCG. Rob is a total big brother. He and the team have been with us through the passion and pain.”
**This Red Z32TT will be for sale on Bring a Trailer!**
The quest for the perfect Z is almost complete as Jas just found one of the cleanest Super White z32s on Earth. That means the red car is for sale! Jas is listing it on Bring a Trailer. We will update this post and social media when the auction goes live so you don’t miss out! For now, enjoy the extensive photo gallery below, and LONG LIVE THE Z!
Lots of pictures in the gallery, enjoy! …[read more]
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!
