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:

 

 

Did we mention that this Z gets driven?!

 

The OMS Pace Car tribute joining us at the 2023 New Z Viewing Event:

 

Linda has been all smiles:

“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”

TUNING: Pat’s 1970 Datsun 2000 Roadster

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 3:11 pm on April 4, 2022

 

Datsun Roadsters hold a special place in our heart and recently we had the opportunity to tune this very beautiful example owned by Pat S. The only reason we don’t work on or build these gems: we simply can’t keep up with our Z car workload. Once in a while though, someone will throw around the name “Alvin” (our shop social media manager) and they will get into Z Car Garage.

 

Pat contacted ZCG to discuss his 1970 Datsun 2000 roadster’s twin-Mikuni carb setup. The 2L/U20 models could be optioned with dual Mikuni-Solex carbs (replacing SU carbs) as part of a factory “competition” package also including a hotter “B” camshaft and 7.5qt. aluminum oil pan. Pat had done all he could to make it drive nicely and wanted a touch more driveability. Once at the shop, Rob took his car for a ride, impressed with how nicely restored it was.

 

Dyno Tuning

 

Rob and Pat discussed his goals and what he wanted to accomplish. We were able to go in and adjust the idle/off-idle settings, and of course wide-open throttle. The U20 put down 113hp/109tq to the wheels:

 

Pat was really pleased with the dyno tuning results. We actually saw him on the recent BCR Tokyo Calling Rally where he said the car was running fantastic and he was stoked:

“I saw Z Car Garage referenced on 311s.org when I was trying to sort out my carbs. I had the carbs completely rebuilt by Taka Sato at Kyusha House (beautiful job) and Z Car Garage did the fine tune adjustments on the dyno. Starts and runs great. So fun to drive! I once had a good friend that owned a high end Porsche shop (he races Lotus’ now) in LA. No matter who you were, if there was any oil or dirt on the engine, he would send them away. Rob reminds me of him. An expert with a true passion for the cars!”

Enjoy the sounds of a Solex-equipped Datsun 2000 on the dyno below!

 

Pat shared his Datsun story with us:

“I bought my first roadster in 1973 and it was a ’66 1600 that I paid $600 for. I’ve always wanted to get another so about 3 years ago I purchased my ’70 2L.  Mike Young of DatsunSports rebuilt the top end and installed a ‘B’ cam for me and has been a true friend by not letting make too many mistakes.

 

The car was striped down to bare metal, rusted panels welded in and a new paint job with rechromed the bumpers and trim.

 

Pat refurbished all of the electrical switches and lights (LEDs now). Gauge expert Jon Frampton refurbished the gauges. Pat also rebuilt the seats and has new upholstery throughout:

 

Enjoying The Ride

 

It was great to see Pat driving his roadster on the BCR Tokyo calling rally where he was all smiles with the tuning results. Here a few shots of him at speed in the foothills of Sonoma, CA.

 

Roadster owners united at the rally’s final stage at Sonoma Raceway (Alvin, Rob, Mike Young, Eric and Pat):

 

Pat you have done a great job on the roadster. Nice work, and we love seeing Datsun owners realize the maximum potential out of their cars. Thanks for your support and Enjoy The Ride!

Z Car Garage CV Axles for Carlo’s Datsun 510

Filed under: 510,Parts,Performance
by Alvin G @ 5:10 pm on April 1, 2022

 

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 Carlo O and the old half shafts were replaced with our ZCG CV Axles. You may have seen this TSR Fabrication-built Dime at events in the SoCal area and we are proud to be part of it!

 

We saw Carlo’s 510 last year at the Japanese Classic Car Show and noticed he was running ZCG CV Axles with an R200 LSD. Great to hear that these parts earn Mario Lozano’s approval and he installed them with ease at the TSR facility in Gardena, CA. Carlo is stoked:

“The ZCG CV Axles were recommended by Mario of TSR Fabrication and we chose them based on anticipated power levels as well as reducing the vibrations associated with my half shafts. Installation was smooth as butter and easy as it gets. Performance has been great, they are quiet and definitely substantially reduced vibrations.”

 

Datsun 510 Dreams

 

Carlo dreamed of having a Datsun 510 and it had to be built by TSR Fabrication.

“I purchased my 510 in 2004 right after I graduated from high school. I was 17 and I remember searching for months, waiting every every week for a new Auto Trader. No online tools or social media like today.  I would check DimeQuarterly every night. Finally found one about 7hrs from home. My Dad and I had a great adventure trying to get it, and no matter what condition I going to buy it!”

In addition to the upgraded ZCG CV Axles this is a full TSR Datsun 510 build. As a young enthusiast, Carlo worked several jobs and saved up to enlist the help of Mario Lozano at TSR Fabrication in 2016. Years later the result is a full, TSR Datsun 510 with SR20DET-power and all the goodies they are known for.

 
 

The body color is Nissan (350Z) LeMans Blue with 17×8 forged AG wheels. More pictures in the gallery below!

The engine bay and chassis sport a full list of TSR specialty parts like their titanium heat shield, full stainless exhaust, JRZ suspension, Brembo 13″ brakes, TSR custom airbox, overflow tank, intercooler, radiator, turbo plumbing, stainless fuel lines and full adjustable rear crossmember:

 

See more of Carlo’s 510 on his Instagram.

Mario Lozano of TSR Fabrication

 

Datsun 510 enthusiasts worldwide are very familiar with Mario Lozano, owner of TSR Fabrication in Gardena, CA. Mario has been creating high-quality, functional and artistic parts for Datsuns over the last few decades, but that is just scratching the surface of his accomplishments and project scopes. We have known Mario for many years and recently caught up with him to discuss his passions (not just Datsuns), current work and future offerings:

Time flies: (L) Rob and Mario at the 2021 JCCS,  (R). Alvin and Mario at the 2005 All-Datsun Meet at Mt. Shasta

 

Mario was a track athlete in school, heading for competitive (Olympic) levels until injuries sidelined that trajectory. Academics then became his focus and this is where a passion and love for Industrial Design was founded. Cars came second and Mario loves 510s, building them for fun while helping the Datsun community. Mario’s personal, SR20DET-powered Datsun 510:

 

While he is synonymous for fabricating high-end Datsun parts, Mario does so much more! From working directly with major OEMs (like Ford and their Mach-E wheels) to F1 and Indy cars…even helping senior citizens with their welding projects! Mario’s favorite material to work with: stainless steel (RathGibson US Mil-spec only).

 

We asked Mario what his favorite part on Carlo’s 510 was, starting with the full stainless exhaust system. He is truly an artist:

 

The custom airbox and titanium heat shield (It’s 13 years old!)

 

Mario is especially proud of the JRZ suspension and Brembo brake systems he designed and fabricated:

“I worked closely with JRZ (we are on V.4) and it transforms the car. Carlo’s wife would refuse to ride in his 510 before the suspension upgrade as it was too bouncy. Afterwards she said it rides like a Camry but handles and brakes…now she wants the same for her 510 Wagon! Smoothest 510 that simply does not feel like a 510.”

 

What can we expect from TSR for Datsun owners? Mario has been offering Carbon Fiber hoods since 1999, but materials have come a long way. These parts are like jewelry and CF trunks are next. A new rack and pinion steering setup, engineered for 510 use with electronic power steering. Finally, Mario is really excited to offer active JRZ suspension!

See more of TSR’s work on Instagram.

 

Thank you for your support Carlo and Mario, it was great seeing you at JCCS!  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:
