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 May.

WE LOVE RACING! Z Car Garage went vintage racing two weekends in a row. On April 21-24, Sportscar Vintage Racing Association (SVRA) hosted the Trans Am SpeedFest at Laguna Seca. On April 28 to May 1, SVRA hosted the Sonoma Speed Tour at Sonoma Raceway. Enjoy our race report with exciting B-Sedan Trans Am race action!

Z Car Garage Race Preparation

 

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. Here is a video of the race cars we prepared this week with dyno passes and a walk around the shop. Enjoy!

 

Z Car Garage Racers

 

Z Car Garage supported the following race cars for the SVRA double-header, more photos in the gallery below.

The Laguna Seca Race 4/21

 

SVRA is an East-coast based group coming out once a year to host back-to-back race weekends in the Bay Area. It’s really fun and allows us roll with East-coast guys we don’t normally run with. Fantastic operation: they do live-streaming of the races, awards with podiums. ZCG was out in full force this year at Laguna with Ed’s 911, Kelvin’s Pacific Datsun 510. New to the gang was Kelvin’s historic 510 (Dragonetti Racing, ex-Ted Gruner) 510, driven by his brother Kenny.

 

This was our first weekend with both Tse brothers and it was absolutely fantastic.

 

As with any race event we had some car issues. On the day it rained heavily we had a transmission problem and ZCG Crew member Nick saved the day, changing a transmission on the wet ground. ZCG even made a guest appearance working on Larry Oka’s 510 (The Mike Bell car) with Greg Hoff driving (of SCCA Miata fame). Greg did really well and he wants a vintage 510 now:)

 

Historic B and C Sedan had a great race where Troy and Steve Link put on a show mixing it up with Mini’s.

 

Rob enjoyed racing, especially chasing Troy. Track photos by Kurt Boden:

“The 4-days at Laguna I was able to finish 2nd in all three feature races right behind Troy Ermish. I was able to out qualify him in one race. It’s really cool to battle back and forth with Troy as he is a phenomenal driver. People came over to say it’s so great to see someone rocking it out with him.” 

 

Enjoy this in-car video from Rob’s Bay Area Datsun Dealers tribute 510 as he battles with Troy Ermish:

You can also catch the SVRA Livestream morning session on YouTube and the afternoon race also on YouTube.

 

 

The Laguna Seca event with SVRA was a success. We towed the cars back to the shop and made sure everything was good to go for the following weekend’s Sonoma race. We miss you Tom Dockery. He had an incident last year but rest assured his 510 will be back in fighting form soon. Super cool that despite is race car not ready he still came out to cheer us on.

 

Special shoutout to Glenn Chiou. He raced his 1973 IMSA GTU 260Z and we are really stoked for Glenn as he cracked off his best lap time of 1:40. He’s one of the youngest “privateer” competitors out there, building beautiful cars. Whenever he needs the assist from the pros at ZCG we are always there to help him.

 

The Sonoma Race

 

We have never attended both SVRA weekends. At Sonoma we had an incredible pit location across from Garage 10 with RacecraftNW and Jim Froula’s band of clients. With Nick and Keith not able to crew were down to Josh, Rob and RN Meghan Fuller:

“Meghan has been my partner in crime for 16 years and this was her first time stepping in…she did all the fueling for cars, learned how to install and torque wheels, work the checklists, vacuum out the cars and confirm GoPros…the feedback from us was awesome.”

 

On Saturday Kelvin broke his transmission so we swapped in one of Rob’s backup gearboxes in at their shop (F7) at Sears Point. He was able to race the rest of the weekend,  and he was in the middl of the field. On Sunday am Troy and Rob battled yet again:

“I was able to beat Troy finally, with quicker lap times. After all the podiums these last weekends it was cool to get that gold trophy from SVRA. Lots of hugs and emotions. Guys in the Ermish camp like Rick Sheldon were congratulatory…nice to be competitors but also share the same love of vintage racing. Two weekends of absolute magic.”

Watch the epic battle between Rob and Troy in the in-car video from Rob’s Bay Area Datsun Dealers 510:

You can also catch the Livestream of B-Sedan on YouTube  from Sonoma Raceway.

Big thanks to Meghan for taking photos and video around the paddock. Here is a highlight reel of what it’s like at a vintage race…you should join us next time!

There were cool cars everywhere in the paddock:

Z Car Garage has been supporting the Nissan/Infiniti Z and G-series sports cars since 2004. At just about any time during the day at our shop you can spot a 350Z, 370Z or G37 undergoing routine maintenance or performance upgrades. Many of our late-model Z car clients are referrals and we are happy to oblige when scheduling allows. We met Frank M in 2020 when he had us perform clutch work on his 370Z. The install went super smooth, and Frank and Rob began their relationship.

“I first heard about The Z car garage through another Z car enthusiast, he had nothing but great things to say about the service he had received working with the crew there. I reached out the Rob to have my 370Z’s clutch replaced with the Z-Speed CMAK clutch kit. That was the first job you all did for me.”

A common issue on the 370Z is the internal slave failing due to heat. Thankfully Z Speed Performance makes a kit to convert the internal slave to external (CMAK Upgrade). We installed their Stage 1 Clutch kit on Frank’s Z:

   

On his next visit to ZCG, Frank had us perform an alignment after suspension work including Eibach Pro-kit lowering springs (KW-V3 coil-overs next) and Hotchkis front and rear sway bars and SPC rear adjustable camber arms. We also replaced the rear diff bushings with new Whiteline parts.

 

Frank is a handy guy and he’s done much of the work on his Z himself. For something that is beyond the scope of a simple weekend project he brings it to ZCG. In summer 2022, with 77k miles Frank installed an oil pressure gauge (VLS) and didn’t like the levels it was reading. There is a very common issue on the VQ37HR where  oil gallery gaskets fail, resulting in low-oil pressure to front of the engine.

 

CPZ makes updated gallery gasket with really nice hardware. At the same time to help with oil cooling we installed the CPZ 25-row oil cooler with a thermostatically-controlled Setrab unit:

 

Wheels Make the Car

Mark has great taste in wheels, choosing a set of Work Racing CR2Pwith Michelin Pilot Sport 4s tires 265/35 and 305/30 rears:

 

We spent time with the 2023 Nissan Z back in June and Frank was kind enough to lend us his WORK wheels to test fit on the RZ34:

 

Frank purchased his 370Z bone stock, being the second owner and has added the following mods:

Drive train 

Fast Intentions stainless steel CBE exhaust

Stop Tech front and rear vented drilled and slotted zinc coated rotors

Stop Tech carbon ceramic pads front and rear

Stillen CARB legal cold air intakes

VLS oil pressure gauge

Aesthetics

Custom retrofitted headlights by me honey comb projector lens. Blue demon eye. Black and gunmetal paint job plus new Morimoto clear lenses.

Evo-R carbon fang cover,carbon type three front lip, carbon upper bumper cover, pearl white base carbon top high wing and CF door handles

Fujimura rear lower diffuser

Enjoying The Ride

You can catch Frank carving up the Bay Area backroads like HWY 9 runs up to Skyline and Alice’s:

 

Frank is stoked with his Z car:

“The performance gains from the work Z Car Garage performed was great. The clutch feel is much improved and does not slip it also seems to shift smoother. The oil pressure is up 15 pounds at idle from the oil gallery gaskets and the car runs much cooler after the oil cooler install. I think the cooler temps help the car not heat soak on hot days while pushing it on back roads. The best thing about the Z car Garage is when I leave my car there for service, I never worry about it being there. I know the car is taken care of as if Rob owned it himself. I have nothing but good thing to say about you all. I do a lot of work on the car myself but Z Car Garage is the only shop I will use if I need the help.”

 

Thanks for your support Frank it was pleasure working with you and seeing enjoy your Z. See more photos in the gallery below, and contact us to schedule an appointment for dyno tuning, maintenance or upgrades on your 370Z or Infiniti sports car!

We love to see owners installing our Z Car Garage CV Axles in their vintage Nissans and Datsuns. This 197o Datsun 240Z is owned by Mark W and he replaced his old CV Axle kit with our ZCG CV Axles.

 

Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 200 sets of axles globally, with customers installing and enjoying them on everything from street cars to full-blown IMSA racers. These CV axles will help transmit power to the ground and ensure smoother operation compared to your standard half shafts.

   

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. 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. Each axle has a serial # for peace of mind and the kit comes with everything you need to install on your car.

  

Mark wanted to eliminate a weak point of the stock half shafts and have a “fit and forget” CV Axle solution to run on his Series 1 Datsun 240Z. He actually visited Z Car Garage from London to pick up his ZCG CV Axles (serial # 0407) and check out the shop:

“After seeing many YouTube videos, articles and photos about the place it was finally my turn to meet the gentleman that is @rawbfuller who runs the place in person, and boy was I in for a treat. I think rob realised I was a little Z mad when I told him I was going to carry a pair of your ZCG CV Axles home in a backpack via Canada and back to London. They were al little heavier than I’d imagined.”

 

Like many enthusiasts, we share the same passion for Datsuns and the sports car experience. We enjoyed showing Mark a few of our fun Z cars:

“Not only did I manage to collect some shiny new parts to bring back for the 240z but Rob was kind enough to throw me the keys to their test car ‘Butters’ to experience all of their hard work first hand. What an incredible driving machine that car is and such a credit to the whole team at Z Car Garage. That not being enough I even happened to show up on a day when Behemoth was in. One of the few Zcars in the world to be running a Twin Cam head on an L series engine. Not only did I get to see this but I also got to experience it first hand, making for an unforgettable day. A huge thank you to all involved 🤘”

 

Datsun 240Z Dreams

 

Mark shared his Z car history with us:

“This is a 09/70 car registered in’71 which I bought off Ebay back in 2016 sight unseen and shipped back to the UK. It was totally stock at the time and I’ve slowly been transforming it into a fast road car while trying to retain a factory aesthetic from the outside. I’ve taken it to LeMans, Spa and toured down to Italy to visit the car factories and complete a rally with Petrolicious.”

 

Some brief specs:  T3 adjustable front control arms, ST sways, BC coil-overs, R32 GTR front brakes with vented disks, S14 5-speed transmission, 3.9LSD, DSI stage 3 engine, 123 ignition, OS Giken lightweight flywheel/clutch and Panasport 16X7 wheels with Yokohama AD08R tires:

 

The exhaust is a Zstory Racesport header going back to a JDM style muffler using their complete system:

  

Mark recently made a switch from SU to triple OER45 induction with a bespoke cold air box setup. We admire his build ethos:

“I love using cars as intended so his build ethos has been to make it functional, reliable and useable as possible with modern levels of performance with L-series charm and soundtrack. .”

    

 

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 150+ 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:

This is the Performance model in Two-Tone Ikazuchi Yellow TriCoat / Super Black and 9-speed automatic. In stock form and 91 octane it put down 345hp/362tq to the wheels. The dyno plot below shows dyno results from the Yellow automatic Z and the Passion Red 6-speed manual Z we dyno tested in June. Super excited to tune the new Z and unlock more power!
