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!
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!
The iconic, 1976 IMSA GTU Championship-winning Transcendental Racing Z is at Z Car Garage! This early 1970 production 240Z has an exciting history battling against factory-backed teams with names like Jack Scoville, Brad Frisselle and John Morton behind the wheel.
The chassis was also highly-developed by a team of All-Stars including Joe Cavaglieri (Crew Chief), John Knepp (engine), Trevor Harris, Mac Tilton (suspension) and Yoshi Suzuka (chassis, roll cage and body). Current owner Randy Jaffe has commissioned Z Car Garage to bring this Z back to period livery, refresh the chassis and drivetrain components, and re-assemble the interior before traveling to its new home in Atlanta.
The Z came with many spares, period photos and even original molds for the bodywork!
Getting the livery sorted has begun, with a proper “Frisselle” windshield banner (left) based on period photographs (right)
Here is a short video of the Z as it arrived to the shop early this week. Dyno testing with video coming soon!
Always Meet Your Heroes
The “Frisselle” car captivated us for many years. We watched it race locally and and eventually shared track time with previous owner David Martin (RIP) at major historic events. (Below, Left) David Martin and Rob Fuller (#49 Joel Anderson car) in the Corkscrew and (Right) Rob with David and Brad Frisselle at the RMMR 2018.
You can imagine how excited we are to have this iconic race car at Z Car Garage. Big thanks to Randy for always believing in us. More photos from my brief visit:
Enjoy these videos we’ve captured over the years racing with David Martin piloting the Transcendental Racing 240z:
In a moment of sheer happiness, Rob Fuller can be seen driving the #47 Brad Frisselle Z through the paddock back in 2015!
A David Vs. Goliath History
Ever wonder about the history behind this famous 1976 IMSA-GTU Championship-winning 240z? Check out www.my240z.com. Our friend Glenn Chiou created this website to document the racing provenance for previous owner David Martin (RIP):
Glenn’s impressive knowledge of historic Nissan/Datsun racing is bolstered by hundreds of scanned photos, some never seen before along with stories from ex-drivers Brad Frisselle, Jack Scoville and John Morton. We are even given new insight on the R&D effort that went into the Frisselle car making it by far, “the best race engineered 240z in its period”.

At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goals reality is our passion. Richard W brought his 1971 Datsun 240Z from Eureka, Ca for a full mechanical restoration, ZCG-style. Our Z Car Garage Big-Brakes, Z Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain and full suspension transformed this Series 1 S30.
In 2017 Richard contacted us to inquire about restoration work. He understood we were booked, and we spoke again later, but this time he visited the shop with a photo album filled with photos of his beautiful, Sunshine Yellow Z.
“I did my due diligence and researched what ZCG could do, and arranged for a meeting with Rob to discuss my car. I asked if he would be interested in restoring my 1970 240 Z. He was pretty adamant, ‘I don’t restore those rust buckets anymore.’ A little disheartened but I persisted. Would you take a look at the album I have of my car? He flipped through he pages and you could see him light up and the enthusiasm came forth. He said, ‘Where is the rust?’. I told him there was none as the car has been indoors for the last 40 years.”
Rob and Richard agreed that since the exterior was in great shape ZCG would perform a mechanical restoration. Richard is in his 70’s and still practices dentistry in the small town of Eureka. After being parked for decades he trailered the Z down and arrived at ZCG in January 2018 . Here is VIN #12291, with 63k original miles:
He bought this Z brand new 12/70 and absolutely adores it, being an integral part of his life for half a century! We love the story behind Richard’s Z lets’ take a look before going into the mechanical work…
Life With The Z
“We all have defining moments in our lives and those moments need to be prioritized. The marriage to my wife of 50+ years is of course the most important moment. She provided the resources to live in San Francisco and was so supportive of my graduation from college. That same year she became pregnant with our first born. We moved to Eureka at the same time. I was able to start my own business in 1970 and begin an adult life. All the important hurdles were checked off. We moved to Eureka with $300 in our pocket and a mountain of debt. But wait, there was one more hurdle…”
“…From across a parking lot, in Eureka no less, stood a bright yellow Ferrari. Upon closer inspection I was even more baffled. What was a Datsun 240Z? I went to the local Datsun agency, long before Nissan came along and made my inquiry. Yes, the new 240Zs are very special and very desirable. They were being shipped in but there is a waiting list. Just add my name. Sure enough they called a few weeks later and said there was an Orange Z on the lot. They made the mistake of letting me wring that car out and I was sold. While I was in school in San Francisco, I saw Cobras and Porsches that cost $6 – $7,000. Way out of my league but I could afford the $3,600 Z. Even if it meant borrowing $1,200. In early December 1970 I took possession of my Z. It became my car and my identity. It has remained just that for the last 50 years.“
“My oldest son was born the following February. Now all the pieces for my life fell into place. Marriage, college, moving to a permanent home, birth of our son and the final piece, my sports car. Being a young family in the ‘70s was simple. We just put Jason between our two seats the Bull Dog in the back and off we drove. No thought of a car seat. Before he was six months old, we had been the 700 miles to San Diego and the 700 miles to Canada. Not a care in the world and a wonderful way to see the country.”
“My car was a daily driver. For the next 20 + years that was my car. As my boys grew up and learned to drive, I needed to provide a car for them for high school. Well, not my car. So, I bought them an upgraded and modified ’71 240Z. I bought the Z because I felt they would be safer in that car. I didn’t want a larger car they would put a lot of friends in. Later on, I heard they actually had put 5 guys in the Z car.”
Of course, over time, tastes changed and Richard succumbed to buying a 1992 Corvette. You know, the ones you fall into and climb out of. Fast forward to 2015 and his 240Z is in the garage, covered with the things a guy collects in a garage. The ‘vette became useless and the family all preferred the Z. This is where ZCG becomes part of Richard’s Z car journey. Let the mechanical restoration begin on this Series 1 that has not run since 1985…
Drivetrain
We got the original L24 with SUs running after sitting for years, but Richard wanted more power and Rob suggested a Rebello 3.1L engine. Supporting parts included an MSA 6-into-1 header, ZCG exhaust system, internally regulated 280ZX alternator, 280ZX gear reduction starter, KOYO race radiator (custom upper hose) and Z Car Garage Heat Shield. Here are a few pictures of the engine build/installation with many more in the gallery:
Powdercoated and plated parts adorn the engine:
Induction is handled by triple-Mikuni PH44 carbs on a Harada intake manifold.
Before/After the engine bay restoration, more details below:
To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. The KA24 unit is significantly stronger than early S30 transmissions.
When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin). Rounding out the drivetrain upgrades are a set of Z Car Garage CV Axles (shown below)
Engine Bay Services
Richard’s Z received a total engine bay restoration. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!
With the engine/transmission removed we focused our efforts on restoring the engine bay. Everything was cad plated or powdercoated. All new fuel hoses, every cooling hose and all new hydraulic lines. Every nut/bolt is bagged and tagged before re-plating.
The Z’s body had been painted once before but the engine bay was left un-touched. We called upon our man William from William’s Auto Body re-spray the 919 Sunshine Yellow and it turned out fantastic. Before/After:
More before/after shots showing fuel pump, hydraulic an coolant lines:
With the new engine/transmission even more detail work was performed:
Final Before/After in the engine bay:
Our ZCG Exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip. Listen to the sound in the video below!
Dyno Tuning
Rob dyno tuned the Rebello 3.1L engine making a stout 199hp/221tq to the wheels. Enjoy the L-series music in this extended video of Richard’s Z including dyno runs, test drive with Rob and drive-bys:
Suspension
Richard’s chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni struts with our spring rates) suspension 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. Richard 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:
Front Suspension refresh with T/C rod, crossmember and steering rack detail:
Rear end with T3 lower control arms and ST Sway bar:
ZCG Big-Brakes and CV Axles
We are proud to have several of our ZCG products on Richard’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) and also upgraded to Z Car Garage CV Axles! These products have 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
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:
We went ahead and got Richard dialed in with the ZCG big-brake kit for small wheels with parking brake and a new OEM Nissan master cylinder. More pics in the gallery!
Front brake installation:
At the rear, the OEM drums brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!
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.
Richard’s standard half-shafts shown on left:
Panasport Wheels
Our ZCG Big-Brakes also look great behind Panasport wheels in our offset allowing us to run 225/50/16 tires (Bridgestone S-007a). The Z was fully aligned afterwards.
Interior
One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors.
We are really proud of the HVAC system in this Z. A vintage A/C unit was modified to work with the factory heater box and OEM controls. Our client Kurt W 3D-printed us a vent part to allow the A/C to blow cold and hard…see the video! We are working on a solution for all our customers stay tuned!
New, high-end carpet throughout:
The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:
Details
The little things are what we excel at. Exterior items include straightening and re-chroming both f/r bumpers. We also removed the 80’s style front spoiler and replaced it with the the correct 3-piece setup from our Series 1 parts stash:
We installed electric power steering, it is a wonderful upgrade see how effortless low-speed steering is in our video above!
Please check the gallery below for more detail shots, there are too many to list in this blog post!
Enjoying The Ride
In December 2020 Richard made the trek from Eureka down to Z Car Garage to pick up his restored Z. After he came back from his test drive it was quite emotional for the two Z car enthusiasts. Rob recalls…
“Richard got out of the Z and told me he had bought this Z 50 years ago that week, it’s been with him through alot of stuff and now his kids and grandkids will get to enjoy it. I looked him in the eye and said I’ll be here for their chapters, any time they need me. I’m attached to this Z now too.”
Richard was ecstatic. It was the reaction we live for at ZCG:
“I delivered the car to Rob and put a lot of trust in him. Nothing happens fast but what happened to my car is truly miraculous. Rob’s attention to detail is unsurpassed. It was just last December that I was able to pick up the car. It was exactly 50 years to the day that I bought the original car. It is not the Z car of yore. Rob had replaced everything. If it was bolted to the frame, all the original equipment came out. From new Recaro seats, interior upholstery replacement and sound deadening. He started up front with the radiator through new larger engine with 3 -2 barrel carburetors to tranny, exhaust system, suspension tires and wheels. It is a brand new car inside but still looks like the Ferrari I saw so many years ago.”
Richard began Enjoying the Ride in his fresh Sunshine Yellow Z back home. He sent us an e-mail of his adventures.
“It has been a whirlwind 4 days in my life. Friday was my drive to San Jose hauling a trailer and all the while the anticipation of seeing the Z after the restoration. Saturday morning was nothing short of exhilarating. There was my little beauty, long in tooth but brought back to its original radiance. Not just radiance but purposeful modifications. What you have done with the car is truly remarkable. It is not the same car beneath that unmistakable glow.
Our visit and talk was also a highlight for me. Your exuberance is contagious. I do so love out of association. You have given me a link to my past and the wonderful times I have spent with Cheryl and my boys. So ends an odyssey that began a few years ago. I could not be happier for two reason. My car has been brought back for me to enjoy and I have made friends with an amazing man. Thank you Rob for all you have done for me.”
Richard, thank you for letting us be part of your Z car journey. We love your passion and connection to your Z. Enjoy the photo gallery and…
