Many of our clients perform work on their Z cars by themselves, and we love to help when they are ready. Kai N installed a bunch of parts on his 1972 Datsun 240Z and got to the point where he didn’t feel comfortable taking it further. He took his Z to several local shops and was not getting it sorted so he visited Z Car Garage. We got him dialed in by sorting out his Weber carbs, brakes and fuel system. Our ZCG Heat Shield also graces his induction setup.
“A while back I installed triple DCOEs, headers and exhaust. I got some professional help to get the car running, but it was not quite right, so I knew my next call would be to ZCG. But before I made the call the pandemic hit, I found myself with a bit more free time and started working on other bits of the car. I ended up working on the cooling system (new radiator, electric fans), fuel system (electric fuel pump), new brakes and suspension.”
Z in the Family
Kai shares his Z history:
“The Z belonged to my Uncle Donnie until the late 90’s. He sold the car to our local mechanic. I’ve always wanted a Z and my Dad always reminded me where I could find Uncle Donnie’s old Z if I was ever ready to own one. When I was finally able to acquire my dream car in 2017, I asked the mechanic a few times if he would sell me the car while I was shopping for a Z, but he was on the fence about it. BTW I think he had 2 or 3 Zs at the time. After a few months of me bugging him, a generous offer and my uncle (along with his friends) putting in a few good words on my behalf, he was finally convinced to sell me the car.”
“I will never forget that after I purchased the Z, my Dad told me a story. Before my uncle sold the car to the mechanic; Uncle Donnie had asked my Dad if he wanted the Z. I was a few years from being old enough to drive and the Z could have been my first car. Of course, my Dad declined the offer. I got my Z, it just happened 20ish years (and a lot of $) late.”
Mechanical Sorting
Kai wanted us to address a list of items and we knocked each one out. Littles things like installing a temperature sensor, replacing motor and transmission mounts, re-wiring his fuel pump and new rack bushings were taken care of. We also sorted out his braking system and nut/bolted the entire suspension followed by a full alignment.
The engine bay was cleaned up, drive belt replaced and we sorted the Weber carbs. Kai purchased one of our Z Car Garage Heat Shields and we modified it to work with his throttle cable linkage:

Dyno Tuning
The triple Webers were dialed in on the dyno. With Rob’s tuning the Z went from running poorly to running well, making 141hp/141tq to the wheels:
Listen to that L-Series music on the dyno:
Kai is really happy with the work we performed:
“It’s a completely different car. It still needs work, but I can finally enjoy the car. I didn’t want a track car or a pristine show car, I simply wanted my Z to be something that I could enjoy. ZCG brought the joy. My Z’s journey isn’t done, it will continue to evolve and I’ll be counting on ZCGs help. I approached ZCG without much of a plan. I think Rob and crew formulated and executed the perfect plan for me (and my budget). The car is fun and safe, while having potential for more growth. I had not driven the car in 2 years, So I’m sure you can imagine how happy I was.”
What’s next for Kai’s Z? He’s driven Mrs. Butters, our 1971 shop 240Z and he is returning to ZCG for our ZCG Big Brakes!
“My experience at ZCG has been amazing, I’m pumped for the next step in my car’s journey. ZCG BBK is next for me! Also being at the shop is cool too, there is always something there that blows my mind (like the BRE Z or the IMSA).”
Thanks for your support Kai, we are honored to be a part of your Z car journey!
Gentry Stein visited Z Car Garage from Chico, CA for dyno tuning on his V1 Nismo 370Z. We specialize in UPREV and EcuTek Tuning to maximize power gains from individual modifications like intake and exhaust upgrades. Gentry contacted us before searching for the right Nismo Z34 and eventually found this super clean V1, #528:
On the dyno, Rob Uprev tuned the Z making great mid-range to redline gains. Peak gains of 9hp/7tq for a total of 322hp/267tq at the wheels:
Gentry is thrilled with the power gains:
“My experience at ZCG was absolutely awesome! Rob’s passion for Z’s can truly be felt while at ZCG. I felt confident knowing my car was in the best possible place it could be to get dyno tuned. Rob even took videos of the car for me while it was on the dyno. The car made great power throughout the whole powerband, and it’s even more of a blast to drive now! The throttle feels alive, and the torque gain is really felt from 4K-6.5k RPM. I’m excited every time I sit in the drivers seat of my Z.”
Yo-Yo World Champion
Fun fact: Gentry is the World Champion of Yo-yo. He provides some insight into his desire for a 370Z and career in Yo-yo playing:
“In early 2020 I was specifically looking for a V1 Nismo Z34 in white. I wanted a car that I could daily drive and also take through canyons and coastal roads. I don’t care about a fancy interior with luxurious amenities. I wanted something that looks sexy and is fun to drive, and to me that’s an exact description of this car. Ive driven some other popular cars, but this car feels rewarding on a different level. I love what they did with the body kit of the Nismo too. You know you have the right car when you can’t help but look back at it every time you get out of it.
My Z story really starts with my love for Japan. I’ve had the pleasure of visiting Japan 5 times over the last 6 years for work and play, and have developed some incredible friendships that have allowed me to experience Japanese culture and values. I started playing with yoyos when I was 8 years old, which is when I met one of my mentors who is from Japan. From then to now as I’ve turned that passion into a career, much of my success is due to what I learned from that mentor as well as my other connections and experiences in Japan. The month preceding winning my first World Yo-yo Championship was spent training in Nagoya and Tokyo. I experienced the special level of care that goes into everything in Japan, whether it’s design, food, human interaction, work ethic, etc… This has played a major role in inspiring me and helping me develop into the person I am today. This level of care is also felt in their Z cars when looking at and driving them. I have such a respect and appreciation for Japan and their culture, and I feel proud to drive a car that was born from the same place as many of the building blocks to my own life success.
As for my goals with the Z, I plan to continue to drive the hell out of it. I’ve put 15,000 miles on the car in my first 10 months of ownership. It’s literally been 15 thousand miles of fun and I’m looking forward to more of that. I’m pretty content with the way the car is setup. The car is riding on KW V3 suspension, has a Wavetrac limited slip differential, polyurethane differential bushings, K&N drop in air filters, Motordyne Shockwave exhaust, and special sauce from the fresh Z Car Garage tune. I also just did a full paint correction and ceramic coat myself to keep the car looking as good as it drives.
Thanks Z car garage for being part of my car’s story!”

On May 1-2, Sportscar Vintage Racing Association (SVRA) hosted the Trans Am Speedfest at Laguna Seca. Z Car Garage was fortunate to participate and support several client’s Datsun 510 race cars running in B-Sedan Group 8. It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with photos and exclusive in-car footage!
Z Car Garage Supports Three 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) and Kelvin in the second video on the dyno prior to the Speedfest weekend. Enjoy the sweet L-series music!
510s Galore!
With ten Datsun 510s in Group 8 it was a Dime-lover’s dream to be in the paddock and watch the races. Although the event did not allow spectators, we’ve got you covered!
Let’s take a look at the Datsun 510s that we supported, beginning with our clients. All of our cars ran flawlessly:
#7 Kelvin Tse
Here is Kelvin’s re-telling of his race weekend with us:
“Driving Laguna Seca during the spring time is a wonderful experience in itself. Racing Laguna with other B Sedans in a well prepped 510 is a racers high on another level. Track conditions were perfect with sunshine and daytime highs in the mid 70’s. The weekend was uneventful as far as mechanical problems were concerned a fact that has not always been the case for me. 5 years and far too many let downs. I have really never had a 510 that I felt like I could just drive at the limit with a fair degree of control. Z car garage has given me a proper race car. MOTOR, TRANSMISSION AND SUSPENSION have been sorted out and now the car could be driven at the limit. I finally was able to trust the car to steer correctly after full compression of the shocks and springs. The car was very predictable . I have also been working on getting use to the new dogleg transmission installed recently and finally have learned how to properly downshift thru the gears.
Saturday Race I started in position 8 and had a battle for every corner with David Murray in his BMW 2002. We pretty much changed positions for every lap. I was excited to have a car that I felt comfortable enough to go door to door racing with. David said that this is the best race he has had in years and I have to agree with him as we were duking it out. On the last lap, he left the door slightly open entering the Wayne Rainey curve and I took it. After passing him I knew that he would try to set me up for turn 11. Well, he did put his nose in there, and we both got thru 11 with me having a slight advantage. Drag racing down the straight bumper to bumper … Yep , the 510 came out ahead. Position #7
Sunday morning … a mix up with SVRA tech paperwork DQed me and put me at the back of the grid. I was listed as a 2L and need more weight to qualified as a 2L.Problem… My car has a 1800cc. In fact I could still loose a 100lbs. hey Rob and Josh next project….
Starting at the back of the grid was not where I wanted to be. So my start was going to have to be something else. Years of racing cars and karts have helped me on my starts. Well , I did get a good jump when the starter started to move his hands up. I dived all the way to the right of the track in turn one kicked up a little dirt and put the car exactly where I wanted on the outside of turn two (SEE VIDEO BELOW). Full power on the inside of turn 3 made me go from the last position to position #6 behind Tom Dockery. Whew…that was fun…We only got in 2 laps before the race was red flagged because of an Alfa who’s driver got out of his vehicle in turn 5. A big no no… Position #6
Overall, Rob was the winner, Tom finished #5 and little old me got a #6. I am still developing and learning how to drive this wonderful car. But what strikes me as a successful weekend is when everything just seems to go your way, the sun is shining and you are out with some great friends having FUN!!! This was accomplished only with the help and support of everyone at Z Car garage. The racing gods were smiling at me this weekend.”
#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:
“The SVRA TA Speedfest was so much better than I expected. Coming in I set myself up for disappointment, mostly because my last experience on Toyo 888Rs was so disappointing, almost scary. But my first practice flushed those fears away. In the first practice I beat my previous PR, breaking the 1:50 mark which I did earlier in the year on fresh R7s. Over the course of the weekend, I continued to set new PR’s finishing up on Sunday with a mid 1:48. I think the trick was me continuing to get comfortable with the new engine and the idea of sliding though a corner. There might have been some additional benefit of the small diameter Toyo tire giving me a final drive the fit really well with my speeds at Seca.
The run group was large with a strong mix of 510’s and 2002s. GTV accounted for just 2 of the 35 cars. Strangely the field set up with all the 510’s qualifying ahead of the 2002s for the most part. My experience with Steve Walker and John Murray suggests this was probably just drivers and not cars. Although I was able to keep reasonably attached to the top five cars (though Troy and Rob were pulling away at a steady rate) I really enjoyed watching my rear view in car video as Kelvin and I pulled away at a pretty good rate from the rest of the field ….. that was fun.
My car was perfect, no issues and ran in top form all weekend long thanks to Josh and Rob.”
In-car video is the Sunday afternoon session from Tom’s 510, enjoy: The rear facing is cool because of Kelvin’s go-kart talents and near Troy-like start behavior. The front video I thought was encouraging has I was able to keep a line of sight and partial contact with people who historically have been much faster than me.-Tom
#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 1:44.068, here is his experience:
“SVRA is mostly an East coast association, coming out West a few times a year so we were happy to be a part of their events. This year they did back-to-back events with a weekend at Sonoma (unable to attend ) and Laguna Seca April 30-May 2. We supported three cars with Josh as crew and myself as driver/crew. All had a great weekend with each car running really well. SVRA rules require us to run a Toyo R888 tire, not as sticky as Hoosier R7s we typically use. Dockery and Kelvin finished in the top 10 with personal best lap times, I am really proud of them. On Saturday I finished right behind Troy Ermish.
Race 2 on Sunday was dramatic. Wherever you finished Race 1 is where you start in Race 2. Troy and Rob were just .002s apart in qualifying!
“To be close to Troy was fun, because he can drive like hell. In Sunday’s race both of us were out in front, a good 3 seconds ahead of the 3rd place car when suddenly an Alfa oiled down the track outside of Turn 4. I saw Troy’s car move around, and then my car got loose. As he moved into turn 3 I a saw strip of shiny oil across the whole tack and as I changed my line to avoid oil I watched Troy go off outside of Turn 4. Most drivers would have tried to correct this and probably hurt their car…not Troy! He drove right through it, foot to the floor dirt-track style. For the next laps I didn’t look in my mirror, just drove the defensive line and hoped I could stay in front…as we approached Turn 11 I could see Troy throw his car into the turn but overcook it…we finished under yellow flag.”
Rob got the checkered flag finishing in front of Troy and took First place on the podium, though not under ideal circumstances…
“I don’t take it as a real win, even though I placed ahead of him. Troy is an amazing driver and I love the challenge he brings. I hope to enjoy many more races with him, under green flag conditions.”
