We live a charmed Datsun life. The Primadonna Z arrived at Z Car Garage today and we couldn’t be happier for owners Jack and Yolanda Atkinson. This is a very special Z car with a history that will be shared in a (deservedly) separate blog post. Briefly, Jack Atkinson built three totally custom 240z cars in the early 80’s. Heavily influenced by the wild IMSA Z ‘s and Porsche 935 bodywork, Jack hand-fabricated the body pieces and affectionately named the cars “Primadonna Z’s”. Only three Primadonna Zs were made. This red car is the first one Jack built, here is a period photo of it:
Jack would go on to build and eventually sell the Primadonna kit, spawning black and white versions:
The whereabouts of the black and white cars have been fairly well-documented over the years, eventually landing (and thankfully) in the hands of caring owners. After Jack sold car #1 decades ago its ownership became somewhat of a mystery until recent events unfolded. We have so much to tell you about this car’s history, from its current whereabouts back to inception in the skillful hands of Jack. For now, a nice primer can be seen HERE.
Datsun Destiny
Thirty-six years later Jack has been reunited with his first creation, Primadonna Z #1. Today the Z arrived at Z Car Garage and we were able to get it started and take both Jack and Yolanda for a spin. It was incredible to see this Z in person and even sweeter to witness the reunion.
Here is short video of Rob and crew getting the Z started and rolling on the street:
Datsun Family
Jack and Yolanda have been a part of our lives since the beginning of ZCG. Being long time members of The Z Owners of Northern California (ZONC) and supporting our shop along the way, we are grateful to them. ZCG will be restoring the Primadonna Z back to its former glory this year! We are also helping the couple finish their LSx V8 engine swap into their “Primadonna” Z32 Convertible. Yes, Jack had to get back in the game after building those 240z cars so he built a Z32 body kit from scratch. Like the S30’s he built, this widebody Z32 has evolved over time:
We are super excited for you both Jack and Yolanda. Long Live The (Primadonna) Z! More updates to come!
At Z Car Garage, the Datsun 510 is very close to our heart. Our hero John Morton piloted a 510 in the Trans Am racing series to put Nissan on the map, fueling every Datsun enthusiast’s passion for hot-rodding the humble economy car. We also have our share of race, personal and project 510s. When Mark G contacted us to work on his 510, we happily obliged especially after learning that it was built by our friend, fellow racer and Datsun 510 guru Troy Ermish.
510 Beginnings
Mark is an avid car enthusiast, growing up here in the South Bay. His first car was a lowered Capri that he tracked in the 80’s at Laguna Seca. He attributes his 510 passion from its rich racing heritage:
“I was introduced to Sports Car racing at Laguna Seca in the mid 70’s. I have been going to most all of the different events ever since. My favorite was Sports Cars racing, Camel GT’s, IMSA, ALMS. Thus the ‘Poor Man’s BMW 2002’, my recent 510 is my third and hopefully last. Number 2 was also brought back from the dead and used to commute and cruise over Highway 17 to Aptos to work for my Father’s business. The surf rack was installed to haul all kinds of stuff.”
In 2015, Mark decided to fulfill his dream of another 510 and bought a project car:
“I wanted something I could turn into a street racer and autocross car for my son. As in any extensive full blown renovation, everything on the car has been touched. I tore it completely apart, soda-blasted the car, personally sandblasted every bolt and part on the car, welded in new floor panels and rebuilt the trunk, back panel and rear valance.”
The project car:
Mark’s extensive bodywork:
“I met Troy Ermish early on in the process, so when the floors and trunk were repaired, the car was trailered to Troy for a full roll cage, front fender wells were cut back and jack points installed in the rocker panels at the “B” Pillars.”
After 18months of bodywork, which Mark was heavily involved with, it was back to Ermish for the final build out. The car was purchased with a 1600 and funky 4 speed, but Mark also scored a 2000cc with two side draft Mikuni’s and a ZX 5 speed transmission. The engine was sent to Rebello for a full rebuild and upgrade to 2360cc spec.
T- Square Brain
Mark studied art in school and his attention to detail throughout the 510 impressive. From the no-frills interior to uncluttered engine bay it’s no surprise that he earned the nickname “T-square brain”. Each time I see this car it reveals another level of fanaticism that reminds me how awesome Datsun-owners are. Enjoy a few detail shots with more pics in the gallery below:
Engine Bay
Devoid of unnecessary bits, the Rebello 2.3 with dual-Mikuni’s takes center stage:
Interior
A tribute to the B-Sedan racing 510s of the 70’s, the interior is spartan with a simple dash, roll cage and OMP seats:
Again, it’s super sanitary in here with subtle color choices and straightforward switchgear. That is Pete Brock’s signature on the dash!
Body
The 2017 Corvette Racing Yellow paint is loud, but in a good way. Mark’s touches here are an exercise in restraint, while harking back to the Trans Am racers he remembered. The white roundel was inspired by our friend Dave Scholz’ Datsun 240z as seen on Petrolicious . 13″ re-pop’d (VTO) AR Libras are the definitive wheel choice here, with contrasting black spokes and chunky Toyo R888 tires:
Sorting at ZCG
The 510 was constructed with both Mark’s skillset and Troy’s finishing touches. After he finished his project, Mark visited ZCG for adjustments and sorting.
ZCG CV Axles!
We upgraded Mark’s standard half shafts to our Z Car Garage CV Axles. These CV axles help transmit power to the ground and ensure smoother operation compared to standard half shafts, while eliminating the need for aluminum adapters. Mark got ZCG VV Axle set #320 and he loves them:
Nick about to install the new CVs:
Standard half shafts (left) and ZCG CV Axles (right). Note all of the powdercoated suspension parts:
Getting Mark Back On The Road
Mark was experiencing a re-occurring high water temp issue. Finally the head gasket was compromised so we pulled the engine for a refresh.
We re-intalled the the engine and tidied up the engine bay. The electric fan was removed and a fan clutch installed utilizing a 620 water pump/S30 fan blade to make it all fit behind the Koyo radiator:
Dyno Tuning
On the dyno, we had a case of deja vu as Mark’s 510 is almost similar to Keith’s. Rob is familiar with tuning the L-Ser-es engine in both race and street 510s. Mark’s Rebello 2360 put own 189hp/178tq to the wheels, gaining 8hp/10tq with Rob’s tuning. You can hear it scream in the video below. Mark will re-visit us for another dyno session after he accumulates more miles.
Enjoying The Ride
With a few more minor tweaks like door locks and windows, Mark was out and about with his 510. He joined us at the local Fuel Supply Cars and Coffee:
I was fortunate to catch up with Mark and meet his son Dom who also has motorsports background. It was rad to see the Datsun being a family affair and Mark all smiles behind the wheel:
“I feel very lucky to be part of the Z Car Garage family. The staff are all great guys. I will continue to bring the car in for Anything it needs.”
Big thanks to Mark for letting us service his 510. We really enjoyed having the 510 in the shop!
Speaking of Love for The 510…this weekend 20+ B-Sedan racers will be running at Laguna Seca. I will have a full report for you, stay tuned!
On July 10-12, the Classic Sport Racing Group (CSRG) hosted the David Love Vintage Races. Our favorite feature race was the Group 8 class with 20 sedans battling at Sonoma Raceway. It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with in-car footage and photos from contributors Kurt Boden, Trent Barr, Nick Dockery and ZCG Crew Nick F and Josh C.
Z Car Garage Supports Three Datsun 510s!
2020 has been a strange year and we were fortunate to be racing again at Sears Point in the David Love event. Z Car Garage both participated and provided support for several Datsun 510 race cars.
Here is a video with sights and sounds from the paddock, samples of in-car footage of Rob Fuller, Tom Dockery, Glenn Chiou and Mike Anderson:
#7 Rob Fuller
ZCG owner Rob Fuller, Bay Area Datsun Dealers tribute car
Rob Fuller has not been in the Bay Area Datsun Dealers 510 since last year’s John Morton Cup. This car was purchased from Larry Oka as an IT car, slowly transforming into a B-Sedan. We sorted out the front suspension and this time the rear was attacked. From Rob:
“We installed the weight jacker set to adjust springs for ride height and a DP Racing sway bar that has the same design as the BRE car. Since the shop was slammed and customers come first, we enlisted our friend and fellow racer Troy Ermish to dial in the rear setup. Josh did final prep on the car and we were ready to go. The car did awesome with the back end of he car making all the difference in the world: instead of hopping around uncontrollably I was able to feed it throttle and negotiate the car in/out of corners. We went from middle to front of pack with Troy and the fast friends from RacecraftNW. Good times.”
You can see footage of Rob in the second race here:
Here is a great video with multiple angles showing Rob battling with Steve Walker (BMW 2002):
#7 Kelvin
Let’s talk about our clients. Three weeks before the CSRG event we got a call from Kelvin and he was testing his 510 that he just got from a local shop. It was sputtering and running poorly and by chance Larry Oka was also testing and referred Kelvin to us. We got him on the dyno and the engine failed. With a quick call to Rebello the engine was sorted, installed back in the the 510 and we handled all the prep work to be ready for the race weekend.
Kelvin had a successful race experience, finally:
“Kelvin has dealt with some issues on the car and this was the first time he had a good time with it. We were really happy for him. That’s why do this: we want more people at the race track driving, not fixing. It doesn’t allow to you to build confidence as a driver. You need to have a car that is reliable and works well so you can focus on you as a driver. Kelvin was super pumped. On test day I drove both Kelvin and Tom’s cars and they are fantastic examples of what a B-sedan can be. All they need to do is knock those numbers down”
Stay tuned for a full report on Kelvin’s 510. His friend Ed M was so impressed with our work that he wants ZCG to prep his sedan as well. Look for full report soon!
#72 Tom Dockery
Tom Dockery drove his Ex-Norm Balzer 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 soon.
Tom’s 510 has an FIA engine so it revs really high making it peaky and hard to drive. Per Tom’s suggestion, a shorter gearset would put him in the powerband and sure enough…always listen to your driver! Tom really got faster and it was great seeing him out there. Car has been flawless.
510 Friends!
Many notable Datsun 510 racers were in the group, all sharing the competitive spirit.
#33 Glenn Chiou
Glenn drove the Ex-Finn/Harris U2.5L Trans-Am ’68 510. This car made its debut in May at the SVRA event at Laguna Seca. Glenn did an admirable job (as always) getting this historically significant 510 back on the racetrack!
ç
Glenn was fast. He charged all the way to the front of the pack, only seconds within Jim Froula and Rob. In-car from Glenn:
It is also worth noting that Glenn is one of the few “privateer” racers in the field. He sets up his own race car in his garage and his crew are friends Erich and Lloyd. We want to congratulate Glenn on the birth of his son! Kudos for racing and being a father!
#38 Troy Ermish
Troy is a phenomenal driver. He helped set up our 510 rear suspension too:) Watching Troy wheel his blue 510 his a thing of madness, finesse, skill and beauty. He took 1st place!
#52 Jim Froula
Race car driver and restoration specialist Jim Froula of Racecraft in the Ex- Harry Stewart Datsun 510. Jim was kind to let us pit with his gang. He’s also a fierce competitor.
David Love race results can be seen below:
A Memorable Racing Event
It was so wonderful to share this experience with our friends and CSRG family. We look forward to another B-sedan event and special shoutout to Troy Ermish, ZCG crew including Nick F, the Corwins Josh and Keith. Running all of the cars above would not be possible without them. Rob is excited for future events:
“Of all the vintage racing I’ve done and been around, the B-Sedan group is where it’s at. It’s competitive, fun and you always have someone to race with. We will attempt to do this again August 8-9 at Laguna Seca. Glenn and I are gathering ~25 cars!. Look for B-sedan to become one of the featured groups with CSRG, SVRA and even HMSA/RMMR!”
Z Car Garage wishes you a Happy 5/10 Day and Happy Mother’s Day! We enjoyed driving our 1971 Datsun 510s on a beautiful day in San Jose. Turbo6, our 80’s revival, is back on the road and running great with its turbocharged 6-cylinder L-series. Look for a full report soon:
