Last week the Brock Racing Enterprises (BRE) Datsun 510 #46 race car arrived at Z Car Garage. Despite being against all odds, our hero John Morton drove this 510 to SCCA Trans-Am series championship victories in 1971 and 1972, putting Nissan on the map and fueling every Datsun enthusiast’s passion. In preparation for this weekend’s Velocity Invitational at Laguna Seca we dyno tested this legendary race car. Turn those speakers up and enjoy the video!
Huge thanks to Nissan and Randy Jaffe for giving us the opportunity to prepare the car. It was surreal to have it in our shop:
We spent hours admiring and pouring over all the details on this historical 510. Note the swirl chamber, BRE exhaust header, oiling system and hydraulics:
The chassis reveals hard-earned battle scars:
Note original Koni shocks, Porsche 911S calipers and oval section of exhaust, more photos in the gallery below:
Living Legends at the Velocity Invitational
Z Car Garage is really proud to announce special guests (and our heroes) John Morton and Pete Brock will be at the Velocity Invitational on Friday and Saturday. This is a rare opportunity to get an autograph and chat with these iconic gentlemen.
To celebrate the 50th Anniversary of the Trans Am (under 2.5) racing series, Z Car Garage coordinated with Nissan Corporate to have the original BRE Datsun 510 displayed with the Horst Kwech Alfa Romeo at the Velocity Invitational. See the actual race cars in person, only at the Velocity event!
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!
