On June 5-6, the Classic Sports Racing Group (CSRG) hosted the Vintage Races at Laguna Seca. Z Car Garage was fortunate to participate and support several client’s Datsun 510 race cars running in B-Sedan Group 9. It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with photos from photographers Raj Narayan, Nick Dockery and Jim Rose plus exclusive in-car footage!

Z Car Garage Supports Two Datsun 510s!

 

It is our pleasure to bring more enthusiasts into the world of vintage racing. Our services do include full race support and car-preparation to help make client’s race days seamless and worry-free so they can focus on driving. One of our specialties is dyno tuning. Before a race weekend we confirm that your car is running well and make necessary adjustments while on the chassis dyno. Below is a video of two Datsun 510 B-Sedans (Rob and Tom) on the dyno prior to the Speedfest weekend. Enjoy the sweet L-series music!

 

 

510s Galore!

 

Plenty of Datsun 510s in Group 9, it was a Dime-lover’s dream to be in the paddock and watch the races. Although the event did not officially allow spectators, we’ve got you covered! Let’s take a look at the Datsun 510s that we supported, beginning with our clients. Both cars ran flawlessly:

#72 Tom Dockery

Tom Dockery drove his Ex-Norm Balzer/Koobation 510. This car made its debut in May 2019 and we are excited to share its full story and profile Tom’s journey into racing.

Tom had a blast here are his thoughts on the race weekend

“Overall, the weekend was great.  Smaller field but the top half of the field was equally fast. I had some good exchanges with Jon Normal, whom I never expected to be able to keep up with, so that was fun. Some dicey moments with Daniel Cagginao, thought his lines were a bit off (Sun race 2). I managed to set a new personal best lap time of 1:46:09 which was great.

My other comment would this ….Every time I watch these in car vids ….and I watch them all the time just to hear the noise/sound, I see places I gave time away and I just want to go back out again. It’s intoxicating. My car was perfect, no issues and ran in top form all weekend long thanks to Josh and Rob.”

 Enjoy this in-car video from Tom’s 510:

 

#7 Rob Fuller

With the assistance of ZCG crew Josh and Keith we also supported ZCG owner Rob Fuller in the Bay Area Datsun Dealers tribute car:

  

Rob performed admirably with a fastest time of 1:41.837, here is his experience:

“CSRG is one of the oldest race groups that we run with. It’s been 20 years since they had a Laguna Seca event so we were excited to participate. They had 9 different run groups and I have been pushing to make Spec Miata part of vintage racing. We tried to get a big group out, but only two Miatas raced with Group 8 (Tim Wright and myself). Despite this, it was fun to start at the back and move through the cars”

   

“The big excitement of course was B-Sedan group. Tom Dockery was quicker than ever, and I was getting closer to Troy Ermish. We really had fun, dramatic racing. First race out (qualifying) I was close to Troy. He and I were a good 3-4 seconds ahead of the field with a nice battle. Race 2 I had a good start and took off, then about lap 4 my car’s transmission got stuck in 3rd gear. We  were so far in front that even with 5-6 laps left in race I was able to adjust my driving style and finished in 2nd place. Pretty proud of that.”

 

 

Race 3 on Sunday was dramatic. Troy and Rob were just .033s apart at the finish!

“In the 3rd and final race (afternoon feature) Troy and I battled again. He started to gap me but car issues slowed his pace. I started to reel him in. The last lap was the closest I’ve ever been to Troy (see video below), and it’s no secret that he’s a phenomenal driver. I definitely want to catch cup to him and race with him when our cars are both 100%.”

 

You can see in-car footage of Rob below:

Datsun Car Corral!

 

CSRG is awesome. Since the general public was not allowed to spectate, they hosted a vintage Datsun Car Corral! Participants were spoiled with FREE parking in the paddock area and full access to the race for the weekend.

 

 

Willie Gutierrez brought his Datsun 510 along with a few friends. My roadster friend Raj Narayan (photo contributor) also attended in his 2000.  They got to enjoy the beautiful weather and day of racing without crowds…amazing!

 

Cool Cars

The paddock was filled with wicked metal. This special Datsun Roadster is a factory “lightweight” model, piloted by Michael Sweeney. More pictures in the gallery!

 

 

 

Thank you!

 

We hope you have enjoyed our report from the 2021 CSRG Vintage Race event! CSRG did an amazing job with the event. Rob’s parting words:

“It was fun to catch up with friends like the crew from Racecraft.  Ex-driver of Tom Dockery’s 510 John Koobation was there. I enjoyed racing Miatas and hangin out with Tim Wright, a famous musician from 3rd Eye-Blind and Primus. We hope October’s event with CSRG will be open to spectators!  Our client Kelvin missed this event but assures us he’ll be racing at Sonoma. None of this would be possible without the help of our ZCG crew Josh and Keith Corwin. If you haven’t experienced a Historic racing event I encourage you to come out, it’s a blast!”

 

*See you in October for the CSRG Charity Challenge in Sonoma!*

Race car driver, restorer and Datsun Historian Glenn Chiou visited Z Car Garage today for dyno tuning on his IMSA GTU 260z race car! You might remember our previous blog post highlighting the ZCG CV Axles Glenn installed himself:

    

Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion at Laguna Seca and we specialize in dyno tuning vintage race cars for the event. Listen to that triple-Mikuni fed L-Series roar on the dyno…Glenn is dialed-in and ready to race!

 

 

The Different Drummer Z

 

Glenn Chiou is our client, fellow racer and friend. He was one of the first to run our Z Car Garage Big-Brakes on his RHD 240Z and actively vintage races both 510 and Z cars. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this race car himself and it is now going back to Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn’s got a passion for re-telling the stories of legendary privateer Z car racers and his current restoration project is the Different Drummer Racing Z raced by Greg Sorrentino. This is a really cool race car with great history and build details behind it.

 

Chassis # RLS30-000024 is a July 1973 pre-production Datsun 260Z chassis that was sold by the factory for one dollar in 1975 to Different Drummer Racing, owned by Greg Sorrentino of Troy, Michigan. It was one of the very first Datsun 260Z chassis and was built by the legendary American fabricator, Ron Fournier. This Z car has been consistently raced for the last 40+ years in IMSA GTU, SCCA Trans-Am, and C-Production/GT-2 classes. You can see more history and details of the build HERE.

 

Thanks for your support Glenn! We we will be rooting for you at the Monterey event!

 

 

 

 

 

 

We love to see our parts installed and used on client’s cars. Race car driver, restorer and Datsun Historian Glenn Chiou is running our ZCG CV Axles in this IMSA GTU 260z race car!

 

Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed set #367 himself with ease:

In 1975, the Datsun Competition Department agreed to support Greg Sorrentino’s IMSA GTU racing efforts by providing him a pre-production Datsun 260Z. Once in Sorrentino’s hands, it was left to his all-star lineup of builders to help him build a frighteningly fast IMSA GTU car:

• Chassis preparation was to the skilled hands of legendary metal fabricator, Ron Fournier
• Suspension duties were left to Mac Tilton
• John Knepp of Electramotive Engineering built the motors for Different Drummer Racing

As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces from historical photos…all from his garage at home.

 

Thanks for your support Glenn! We we will be rooting for you at the Monterey event!

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.

   

Beneath the triple-Mikunis is our Z Car Garage Heat Shield, serial #00250:

 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:

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:

 

 

Richard was ecstatic. It was the reaction we live for at ZCG:
