IN MEMORY: RIP Jack Atkinson 1954-2022

Filed under: 240z,Automotive History,Events,Z Proto,z32
by Alvin G @ 2:40 pm on October 24, 2022


Jack Atkinson, friend, extraordinary designer, fabricator and creator of the Primadonna Z, left this world on July 15, 2022. He was 68. Jack and his wife Yolanda have been a part of our lives since the beginning of Z Car Garage. We send our deepest condolences to Yolanda and their family.

 

Being lifetime members of The Z Owners of Northern California (ZONC) and supporting our shop along the way, we are forever grateful to them. This is our tribute to you, Jack. We miss you and know you are out there Enjoying The Ride!

Design and Fabrication

 

In the automotive space, Jack was a visionary designer and self-taught fabricator. Many enthusiasts in the Nissan/Datsun community to this day are still impressed with his iconic “Primadonna Z” based on the 1970’s Datsun 240Z sportscars. 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. In 2021, Z Car Garage helped reunite Jack and Yolanda with his first Primadonna Z build:

 

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. The white car (known as Jettlag) and red car (known as Z Bait) are currently with Eric and Allison Knutsen of Southern Florida Z. 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 was reunited with his first creation, Primadonna Z #1. 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. This would be Jack’s last ride in the car he built by hand before he passed.

 

Here is short video of Rob and crew getting the Z started and rolling on the street:

 

Back in Z Game

After a 20 year hiatus, Jack’s creative mind and passion urged him to get back into modifying Z cars. This time he chose the Nissan 300ZX (Z32) as his canvas, building two “Primadonna Z32” sportscars.

 

The first Z32 was a 1993 convertible (above) that was transformed into a widebody with several iterations of livery, wheels and color schemes. That was Jack: always seeking to improve his designs:

“I wanted to take an already nice looking Z and make it look like a super car. Even though this car is a one off, my insurance is the complete set of molds, from which the components you see were made. I made the fiberglass molds from the hand-sculpted prototype body of wood, aluminum, styrofoam, fiberglass and bondo. Body components were constructed using hand laid S-Fiberglass, Carbon Fiber and Kevlar and rolled out with a high temperature resin.”

The build started in July of 2005 under a canopy in his backyard and took 6-months to complete-including paint. Below, build documentation and the Primadonna Z32 in all-black:

 

The second Z32 was a 1996 Twin-Turbo with only 13,400 miles on it. This stunning ZX was one of the last Z32s to roll off the line (#247 of the last 300) and Jack’s hand-made body-work highlighted the car’s lines, while leaving the ‘looks-new’ interior in full view through the windows and t-top. Jack garnered many awards for both Primadonna Z’s including Best of Show and First Place at ZDay in Pismo Beach:

 

Jack’s LS3-Powered Z32

 

Jack developed a love for Corvettes and we helped him bridge his passion for the Z by performing an LS3 engine swap into his Primadonna Z32 Convertible. This was a dream come true for Jack, earning him a prize in the Z32 Ultra Modified category at ZCON 2021. Here are a few photos of us wrapping up the LS3 swap with road-testing and dyno tuning. Full report soon!

 

It even sports full A/C and OEM shifter for the automatic transmission. The Z was loaded up with the OMS pace car and heading to ZCON 2021! You can hear Rob discuss Jack’s LS-powered Z on this episode of Hoonigan Autofocus with Larry Chen from the 34th Annual Z Car Convention (ZCON) hosted by ZCCA in Colorado Springs.

 
 

Fellow Z car enthusiast and ZONC board member Ann Devor on Jack’s creative work. Jack inspired many Z-car enthusiasts, including younger folks:

“Jack, with Yolanda’s assistance with fiberglass molding, designed and fabricated all manner of auto body parts – fenders, noses, tails, splitters, wings, all to accommodate the bigger wheels that were necessary for his aerodynamic designs. And the wheels were big! Wheels for Jack’s cars were custom made and it was always one of his favorite jobs to put his new wheels on for the first time. And to his last days, he wanted a set of new wheels for one of his cars. Jack was always thinking about the next big thing he wanted to do, whether it was a road trip or a new design for a car.”

“When Jack started working with vinyl applications and graphics, a whole new world opened up and added to Jack’s already respectable number of design innovations. Jack’s cars visually popped with their huge wheels covered by muscular fenders, big wings, splitters just barely clearing the asphalt, and car paint clothed in colorful spears, stripes, arrows, and emblems. There is nothing else like Jack’s cars.”

Roadtrip Leader

 

Some of our greatest memories of Jack are the numerous roadtrips he led (with Yolanda’s help, of course) with ZONC. These memorable drives would kick-off at Z Car Garage, with Jack briefing a large group of enthusiasts. You could also count on seeing Jack’s car equipped with a CB radio antenna, whether it was a Z car or NSX. This desire to share the road and its adventures carried with him later in life to the Santa Clara Corvette club where he would lead them on epic cross-country drives.

 

Datsun Family

 

Jack and Yolanda have supported Z Car Garage since we opened our doors in 2004. They helped us design and produce special t-shirts and swag (more on the way!) that you may have seen at various race events and gatherings. We are forever grateful for their friendship.

 

Love. Jack and Yolanda were in love for 43 years. Their partnership was inspirational, doing everything together including working side by side as business partners and enjoying automotive hobbies. Indeed, it was tough to get a picture of them apart, so most of my photos are of them together 🙂 Here are Jack and Yolanda in 2008 at a Z Car Garage dyno day, in their NSX:

 

We Miss You Jack

 

On October 22, Z Car Garage attended a Celebration of Jack’s Life in Bakersfield, Ca. There was an incredible outpouring of love from friends and family at the event. Jack’s passion and love for sharing spanned across different marques, eventually reaching NSX and Corvette clubs.

 

The celebration of life also brought people together. We met Eric and Allison Knutsen, current caretakers of the Primadonna Z cars all the way from Florida. The parking lot was a mini car show with Jack and Yolanda’s cars as well as friend’s rides. We think Jack would be right at home seeing the gathering of cars and people. Enjoy the photo gallery below:

 

Jack is at peace, and his story will continue to be told. We were fortunate to be in his presence and cherish the time we spent Enjoying The Ride. He truly embodied the words Mr. K said best, “Love cars. Love people. Love life.” Our sincerest condolences go out to Yolanda and Jack’s family. We will miss you Jack!

More Power: Derek’s R35 GT-R

Filed under: Featured Cars and Projects,Performance,R35
by Alvin G @ 8:45 pm on October 21, 2022

 

At Z Car Garage we are fortunate to be a part of our client’s sports car journeys. We first met Derek Y in 2014 when we worked on his 2005 Infiniti G35 back. A few years passed by and he visited us with his latest Nissan, this 2015 GT-R:

 

The R35 had only 11k miles and ZCG installed a host of power upgrades from AMS, EcuTek, SpecialtyZ, Turbosmart and more. You can read about this work from 2019, including the E85 flex-fuel and exhaust upgrades all in this previous blog post.

 

More Power and a New Look

 

Derek latest visit was earlier this year for dyno tuning, interior items and AirLift installation. When it arrived at the shop this R35 sported a complete Varis Kamikaze-R Ver. 2 widebody “Super Sonic” kit and Varis Kamikaze-R Ver. 2 Vented Carbon hood. The Air Lift 3H air suspension strut kit was installed with polished 5 gallon tank.

 

We ran all of the air lines, checked ride height and clearances for the slick Advan R6 Candy Red wheels (20×11 +15 front – 20×12+20 rear) with Toyo R888R tires (305/35/20 Front – 325/30/20 Rear), more installation photos in the gallery below:

 

We also installed a new, Overtake 100-V Saikou Exhaust:

 

A few minor items like a new battery, TPMS sensors in the new wheels and a final health check for Derek’s VR30DETT…but first we performed a re-tune with Ecutek for even more power.  Our last dyno session yielded 612hp/604tq to the wheels and it left with 640hp/622tq. What’s impressive is that this remains a supercar that’s easy to to drive:

 

Enjoy these dyno runs:

 

Interior

 

Derek had several interior items for us to install including: Mines Steering Wheel, Nismo Cluster, Nismo cluster shroud and shiftter paddles:

 

Derek is happy with the latest upgrades to the R35:

“I have been going to Rob for a while now, he worked on my car october 2019 (bolt on and e85 work done) and again recently with a new tune and air suspension and some interior mods. The work is always great its making more power now and more responsive linear power.”

 

 

Here are the SpecialtyZ 3″ intakes and AMS front-mount intercooler being installed:

 

More engine bay work including the AMS crankcase breather setup, ID 1300cc injectors (plus DW fuel pump upgrade), Turbosmart BOVs and a SpecialtyZ Flex-Fuel kit:

 

AMS crankcase breather being plumbed:

 

Stock vs Turbosmart BOV:

 

On the lift, AMS cat-less downpipes are installed:

 

At first glance it is difficult to catch all of the power upgrades in the engine bay, Stock (L) vs Modified (R)

 

Derek also needed new tires so we mounted fresh Michelin Pilot Sport4S sized 245/40/20 and 285/35/ 20.

Dyno Tuning

Back in 2019 , Rob dyno tuned the GT-R using an EcuTek flash and Derek also received a USB dongle for datalogging. Baseline power was 495hp/446tq with final numbers of 612hp/604tq to the wheels on E85:

 

A few plots showing the tuning session: Baseline to 91 octane tune with gains of 65hp/93tq (Left), and the final E85 tune for even more gains of 52hp/51tq (Right):

 

Video of the R35 on the ZCG dyno:

 

Thanks for letting us work on your GT-R Derek and enjoy the boost!

Dyno tuning The 1971 Datsun BRE 510

Filed under: 510,Automotive History,Events,Racing
by Alvin G @ 5:10 pm on October 12, 2022

 

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!

 
 

See you this weekend at Laguna Seca!

RACE REPORT: Back to Back vintage racing events with SVRA

Filed under: 240z,510,Events,Racing
by Alvin G @ 5:10 pm on September 22, 2022

 

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.”

 

Rob Fuller taking P1 at the Sonoma Speed Tour hosted by SVRA.

 
 

 

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:
