Mark your calendars for June 5th to celebrate Z Owners of Northern California (ZONC) 50th birthday at the Blackhawk Museum in Danville!
The Z Owners of Northern California (ZONC) is one of the oldest Z car clubs in the nation. In its prime they had over 600 members with close ties to Yutaka Katayama (“Mr. K”) and Nissan USA. Of the many events and fun runs they host throughout the year, the famous Blackhawk Museum will be the venue for the June 6 birthday party.
Local Datsun specialists/racers Troy Ermish and Rob Fuller will be displaying their race cars. Datsun and Nissan cars will be on the plaza and lower lots for everyone to see. Z you there!
Richard W brought his 1971 Datsun 240Z from Eureka, Ca to Z Car Garage for a full mechanical restoration back in 2020. 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.
With a few thousand miles on the build Richard visited ZCG earlier this year for routine maintenance. We changed the fluids, resolved a charging issue, checked the driveline and overall health of the Z.
While the Z was with us we performed extensive road testing with acceleration, freeway cruising, dyno runs and more all shown in the video below. Turn those speakers up and enjoy!
I could not resist taking more photos of the engine, interior and chassis on this gorgeous Sunshine Yellow Series 1. Enjoy some photos from his recent visit and of course zcarblog has the full report on our restoration of Richard’s Z.
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:
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. 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).
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! Final Before/After in the engine bay:
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.

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.
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 200+ CV axle kits on customer cars and we are stoked with all of the positive feedback.

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.
The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:
Please check the gallery below for more detail shots, there are too many to list in this blog post!
Enjoying The Ride
It was great to see Richard again and meet his wife this time, recalling how he purchased the Z new in December of 1970! We love that this restoration is out on the road and being enjoyed. It’s also a great example of how no matter how far away you live from Z Car Garage we will help our clients any way we can. Long Live The Z!
“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.”

We love to see owners installing our Z Car Garage CV Axles in their vintage Nissans and Datsuns. This 1971 Datsun 510 is owned by Dirk D. and he replaced his failing CV Axle kit with our ZCG CV Axles. You may have seen this Specialty Z-built Dime at events in the SoCal area and we are proud to be part of it!
We saw Dirk’s 510 last year at the Japanese Classic Car Show and noticed he was running ZCG CV Axles with an R200 diff and Quaife (ATB) limited slip differential. Great to hear that these parts earn Sebastian’s approval and he installed them with ease at the Specialty-Z facility in Simi Valley, CA. Dirk is stoked:
“After receiving them I was even more impressed. Sebastian said the installation went very smooth. I’ve been running them now for over 2000 miles and haven’t had any issues. Even after putting the wood to it a few times. And the fact that we put 498 horse power to the rear wheels proves to me that they are high quality”
Datsun 510 Dreams
Dirk has bee working for 10 years perfecting this 510 mechanically and visually. Here is a brief overview…
MOTOR: SR20DET Red top, Mazworx intake, 1320 Injector dynamics, dual scroll exhaust manifold with Garrett 30 GTX twin Scroll, Forged Pistons (CP), Rods (Eagle), ARP Studs, O-Rings, BC Stage 3 Cams (Adjustable cam sprockets), R35 GTR PRP Coil Kit, S15 Oil pick up, High Capacity Oil Pan, Setrab oil cooler, modified Mishmoto radiator, OEM Nissan Fan Clutch, High Capacity Fan, Canton remote oil filter
DRIVE TRAIN: 5 speed, RPS Carbon Fiber Clutch, Pressure Plate & Fly Wheel (billet aluminum), Custom Built Drive Shaft 300ZX Yolk & U Joints, ZCG CV Axles and Power steering.
Sebastian at Specialty Z dyno-tuned the 510 using a Haltech ECU with maps for E85 and 91 octane fuel. It made 369whp at 16psi and 498whp at 20psi. Enjoy this video of the dyno pass:

Dirk’s 510 was featured in the February 2019 issue of D Sport Magazine:
Enjoying the Ride
Dirk has been driving his 510 everywhere, most recently to the Petersen Museum Japanese Car Cruise-In last weekend. Both Sebastian and Dirk are impressed with the Z Car Garage CV Axles:
“Sebastian from Specialty Z told me about your axles after informing him that I just snapped a set aftermarket CV Axles the first time I put the wood to it. So I decided to upgrade to ZCG CV’s. I thought that weak link was going to be an issue that was unsolvable because prior to your CV’s there was nothing on the market that would hold up to the power that this car has. It’s great you guys have offered this solution to the market.”
Dirk purchased this 510 with the SR20 swap already in it, assuming it was a turn key car. Unfortunately the engine failed due to the previous owner’s tuning and 76 mm turbo. Dirk knew Sebastian for quite awhile and talked him into helping him rebuild the car to its fullest potential.
“I wanted a car that wasn’t only for drags or track but could also be driven as a daily driver and still haul ass. With no cooling or tuning issues whatsoever. With major help from Sebastian at Specialty Z and Jamie @ Fab Tech I’ve got everything I asked for and more out of the car couldn’t be happier.”
We asked Sebastian what his thoughts were on building Dirk’s 510:
“The thing I enjoyed most about Dirk’s 510 project was that it was something that we normally don’t do as far as the platform goes. So it was new and refreshing. We never worked in depth with the SR20 in the past or the 510 chassis. We stuck to high quality (as we usually do anyway) parts for the build so it was hard to leave others out, overall we were happy with the fit and finish of the Mazworx intake and exhaust manifolds. We used a Garrett GTX 3076 for the turbo and Garrett never disappoints. As far as the drivetrain goes, the ZCG axles were a pleasure to install and the quality was second to none. We had issues with the previous axles and immediately noticed the difference in noise (lack of) and even a nicer feel while driving the car.”
We have known Sebastian for many years and Specialty Z is a legendary Z32/late-model Nissan tuning house. Seb is a trusted friend and is always willing to help ZCG. It goes without saying that his shop is top notch with many high-profile projects like tuning pro-racer Chris Forsberg’s TT 370Z. Time flies: (L). Ginash and Eric from JDM Legends at SEMA. (Below) Rob and Seb at Z Car Garage:
You won’t see too much from Specialty Z in regards to Datsun related work, but we frequently refer local clients to Seb that have late-model powerplants. Indeed, we sent Bay Area local Jose P to SPZ for tuning on his SR20-powered Datsun 510! We are also super excited to see Seb restoring our Box-flared Datsun 510 that he purchased it from Rob a few years ago:
Seb plans to run a Rebello 2.2L with dual-Mikuni induction, here are a few photos from fresh paint and assembly:
Thank you Dirk and Sebastian for your support! Happy to see you enjoying the Z Car Garage CV Axles in the Dime. Enjoy The Ride!
We have many more photos in the gallery and 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 200+ 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:

We love to see clients installing our Z Car Garage Big-Brakes on their Z Cars! This is Mike’s 1972 240Z with original matching L24. It was bone-stock and sitting for 16 years outside until he rescued it year and a half ago. Mike is a professional automotive paint technician and this Z will be restored with correct 115 metallic blue paint.
Client’s often ask if their wheel will clear the ZCG Big-Brakes and we offer a a caliper template to help with fitment. Sometimes it’s best to physically test fit the actual wheel desired. Mike sent us a pretty rad Star Shark wheel from Washington and we confirmed clearance of the Big-brakes:
“I chose the Colin Project Star shark wheel 14×8-13 for some JDM nostalgia, the look, and a bit more aggressive stance. They are wrapped in BF Goodrich 225/60r14 tires. I very much wanted to upgrade the brakes with the Z Car Garage Big-Brake Kit after seeing Larry Chen’s Ole Orange Bang done by Rob and ZCG team. Sent Rob a wheel for an accurate verification of fitment, and Huzzah!! They Fit! Very, very excited about this. You can’t just put any brake kit on this car. This is a kit that you can have confidence in because the research and development has been done.”
We are really stoked to see Mike’s restoration progress. Thanks for your support Mike and Long Live The Z! You can see more information on our Z Car Garage Big-Brakes and see a list of clients (over 100!) using them on our blog.
Z Car Garage is proud to bring this 1972 Datsun 240Z OMS Pace Car back to life for our long-time client and friend Linda Williams. Only 50 of these Ontario Motor Speedway (OMS) “duplicates” were created and this is one of only two known survivors .
Join us as we revive this historically-significant Z from its slumber to make it a nice driver for Linda while retaining its survivor status. In addition to documenting ZCG’s work we will look at this Z’s history, our relationship with Linda and share her Enjoying the Ride.
History and Acquisition
Before we dive into the OMS Pace car story let’s take a look at Linda’s Z-car story. We first met Linda in 2008 when she reached out to Z Car Garage for work on her low-mileage 1978 Datsun 280Z:
“I had just bought my blue 1978 280Z and had taken it over to Steven’s Creek Nissan Parts Department to have a replacement key made. One of the guys came out and suggested I show it to “Rob” at Z Car Garage. It was my lucky day as ZONC was having a meeting and a Dyno Day at Z Car Garage! Of course, I didn’t know who Rob was and he was busy but took a few minutes to look at my Z. That’s how I met Rob and began a great friendship and a wonderful working relationship. I also joined Z Owners of Northern California (ZONC) that day too!
Linda became a big part of the local Z car community and eventually became (currently) President of ZONC, one of the oldest Z car clubs in the nation. We have enjoyed helping her keep her Z cars on the road over the years, from Car Show prep to routine maintenance:
“Rob has taken very good care of my car and I have a lot of respect for him as a business person. He is honest, open and I don’t feel pressured to do anything on the car that isn’t necessary. In 2012, Rob called and asked if he could ‘borrow my car’ and of course I said ‘yes’, but can you please explain? He then told me he wanted to display it at the San Jose Auto Show in January 2013. I felt honored having it displayed with another restoration Z Car Garage had done, along with many other client Z’s.”
The OMS Pace Car Duplicates
Nissan Motors created 50 “Pace Car Duplicates” to commemorate the Datsun 240Z being selected by the Ontario Motor Speedway to Pace the 1972 U.S.A.C. California 500 Championship (shown above). The cars were originally brought over from Japan by Mr. K and were all white with red interior. The blue livery was added here in the states with the “O” that represented the Ontario Motor Speedway. After the race, the cars were given to Datsun Dealerships in the Los Angeles area as a promotion and later sold to the public.
Fast forward to 2021 and Linda has located one of the Pace Cars: (shown above) The OMS Pace Car in a period photo from the previous owner in Glacier National Park, and on the day Linda purchased it:
“In August of 2020, a gentleman from Porterville, CA who was handling his father’s estate contacted me and asked if our car club (ZONC) would like to have a car (actually 3 cars) donated to us. I had to explain that we were a 501(c)7 and not a 501(c) 3 and would not be able to accept them, but I was personally very interested in the Z and that began the quest to acquire it.”
We told Linda this was a “must buy” as the car advertised had original paint/interior, 45k miles and above all it was 1 of those 50 “tribute” cars made by Nissan. Of those 50 cars, it is currently one of only two known survivors! You might be wondering what happened to the actual OMS Pace car? This is what makes Linda’s tribute Z special, beyond its rarity…as per Carl Beck and other noted Z-car historians, the original OMS Pace Car car was this Z shown below (L):
Above (R) is a photo of Mr. K presenting the keys to the Datsun 240Z Pace Car to Mr. John Cooper, President of Ontario Motor Speedway. This Z was used as the Official Pace Car for the ” California 500″ held on Sept. 3, 1972. It really is a small Datsun world and amazingly this exact car is in our shop at Z Car Garage…it is none other than the Joel Anderson #49 IMSA GTU 240Z !
After running as the official OMS Pace Car in 1972, it was purchased by Joel Anderson from the Datsun Competition Dept. for $1.00 and Joel picked it up at Sears Point from Bob Bondurant in 1979. Joel prepared the Z for IMSA GT-U competition sporting wide aero and his iconic black livery. Yes, #49 still has the checkered flag holder in the driver’s rear quarter panel from its OMS career. We are stoked to have both Tribute and original OMS Pace Cars at the shop!
Z Car Garage Revival
Linda had the OMS tribute towed to Z Car Garage and we sat down to discuss the future of the car. We both agreed to keep it as original as we could, while updating critical parts to bring it back to life and make it a safe, fun car to drive. Our goal was to have it ready for the 34th Annual Z Car Convention (ZCON) in August of 2021.
“My plans are to drive the car and enjoy it as a ‘survivor car’. It draws a lot of attention and I love sharing it with the car community, and telling her story to those that haven’t heard anything about the Tribute cars. I have the paperwork back to the original owner, many invoices that corroborate the mileage and original Warranty Book with the ‘credit card’ warranty card.”
Indeed, Linda has a treasure box of period photos/records all relevant to her OMS tribute Z:
Engine
The Z had not been running since 2006 so we went through the fuel and cooling systems, suspension, brakes and supporting parts to make it a fantastic driver. Starting with the engine bay, we performed general clean-up of the inner fender/firewall areas.
A fresh set of Z therapy SU carbs were installed along with an MSA 6 to 1 header and full ZCG exhaust system:
All coolant hoses were replaced and radiator refurbished:
Fuel tank refurbishment with new hoses and all new evap lines:
On the dyno, the stock L24 made 120hp/125tq at the wheels:
Enjoy this video of the dyno run and a walk-around of the Z after our revival:
Chassis
With respect to the low mileage of this chassis and provenance we performed a “sympathetic” refresh to make it road-worthy. The suspension was removed and replaced with new hardware and bushings throughout. New parts from Techno Toy Tuning included adjustable T/C rods and rear lower control arms. Before/after shots below with more in the gallery.
New tie-rods, rack bushings, and engine mounts. KYB strut inserts, Eibach lowering springs trimmed Macpherson bumps stops for full travel and a ST sway bar set:
We rebuilt and replaced all factory brake components including new calipers with Stoptech rotors, rear drums/shoes+wheel cylinders, new wheel bearings front and rear:
Fresh brake master cylinder and booster:
New drum brake components:
Details
Finishing touches for Linda’s Z included completing the OMS livery. We did not repaint the car because of its survivor status. A cut/buff was sufficient, and “O” decals were sourced/applied just before heading to ZCON. As it arrived (L) and after (R):
Interior
The original interior was refreshed with a nicer set of seats from fellow ZONC members Paul and Ann Devor:
All weatherstripping was replaced from hatch to doors.
Small details like a a new shifter gasket, heater core/ducting refurbishment and window regulator sorting make driving enjoyable:
Enjoying The Ride
Linda drives her Datsuns. We got the OMS Pace Car tribute in great mechanical shape and she has been driving it everywhere on local runs and gatherings. Most recently on April 10 she joined fellow Z owner Bryan for a local Bay Area drive and the odometer turned 47,000 miles!
In March she completed a 300-mile Breakfast Club Rally with us in Sonoma, CA. The OMS Pace Car ran like a champ, handling the twisty roads with zero mechanical issues:
In August 2021 we finished preparing the Z just in time for the 34th Annual Z Car Convention (ZCON) hosted by ZCCA in Colorado Springs. The OMS car was well-received at the show, Pete Brock approved!
At ZCON with the new Z and track laps!
Photographer Larry Chen and Rob Fuller highlighted Linda’s Z in their walk-around from ZCON, enjoy:
“When I bought the car, I did not drive it due to it not being operated for so many years. The last thing that I wanted to do is possibly damage it before I even got to drive it. When I delivered the car to Rob, he went through it and did everything he could to maintain the ‘Tribute Car’ provenance, yet give me a car that I could enjoy driving. She is kept garaged, but she’s driven and enjoyed. The car drives like a “Z” and I am so thrilled that Rob did his magic with her.”
Thank You!
Z Car Garage thanks Linda for her unwavering support. We love your passion Linda and how you wave the flag for Nissan/Datsun history. The OMS Pace Car tribute is in great hands for the next generation to appreciate. From Rob:
“We live for this. Finding these hidden gems that have been sitting and bringing them back to life because Datsuns are Driven. Linda’s Z became a wonderful driver that puts a smile on my face not only when I’m behind the wheel but when I hop out and look back at it. How small and magical is this Datsun world where we can have the actual pace car (1 of 3) and tribute (1 of 50) in the same shop and work on them both. Thanks to Linda for believing in ZCG”
