Ready to Rally with LS Power: The Bartel’s 1973 Datsun 240Z

Filed under: 240z,Performance
by Alvin G @ 2:40 pm on October 12, 2024

 

At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, helping a client realize their vision is our passion. The Bartel family shipped their 1973 Datsun 240Z from Arizona for mechanical and cosmetic sorting, ZCG-style. Our Z Car Garage Big-BrakesZ Car Garage CV Axles, chassis tuning and dyno tuned LS3 V8 engine transformed this Z into the dream car Jeff and son Ryan enjoy at rally events.

 

The Bartel’s Z Story

Before we dive in to the project let’s hear how the family got their Z car…

JEFF: My son and I began looking for a Datsun project car for pre-1975 Targa rally driving events in late 2018. We scoured the internet for resto-mod 510’s or S30’s that with modern drivetrains for reliability and maintenance. After a long and exhaustive search we came across a 1973 Datsun 240Z with an LS3 V8/T56 on one of those trendy online auto auction sites. On paper the car appeared to have just about all of the desirable upgrades, including larger brakes from an OEM, coilovers, a LSD diff, aluminum radiator, fender flares, 17” wheels, Vintage Air air conditioning, fuel cell, decent gauges, extensive body work and paint and nausea-inducing rear wing. We decided to  bid and won what seemed like Z at the right price…

 
Upon test driving the car and wearing the most rose colored glasses one could wear, we still found that there were a lot of issues. Soon after ownership we took the car to a couple of repair shops to get our list of issues addressed, but quickly found the level of service and Z Car knowledge to be lacking everywhere. After coming out of those suspect shops we entered our first CA Targa event early 2019, and couldn’t even complete the first day of the event. A combination of broken diff and clunking suspension cut our event short. We decided to give Rob and Z Car Garage a try after seeing so many of their successes online.

 
 

Mechanical Sorting at Z Car Garage

We agreed to inspect the car and during that process found many of the car’s important systems were in need of complete replacement.

ROB: It was very important to Jeff and Ryan for this Z to be enjoyable and up to the task of vintage rally events. We obliged to help them with that goal in several visits. I was Z car purist when I was younger, thinking one should always install Nissan engines into a Nissan… with time and wisdom it is hard to deny that LSx engines are pretty stellar with respect to power and packaging. It was time to make this Z a ZCG-style LS-powered S30.

 

JEFF: While tuning and driving the car Rob noticed that the existing fuel pump system was not providing sufficient fuel to the engine especially during spirited cornering (not to mention extremely noisy fuel pump and strong fuel smell in the cabin). Rob and his team replaced the underperforming fuel pump and delivery system, relocating the pump to a safer and quieter location, installed a Hydramat fuel pickup system in the fuel cell to avoid starvation during heavy cornering. A new dual exhaust system with X-pipe was also installed from headers back to the tips to improve flow and clearance.

  
 

Z Car Garage Big-Brakes

We are proud to have several of our ZCG products on Bartel’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) which have the been standard on numerous ZCG builds. As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever.

 
 

ROB:  A staple of the ZCG upgrade package is a set of brakes. So we did the ZCG BBK, with new brake M/C and new booster. Factory handbrake functionality IS retained! Suspension was upgraded to T3 f/r coil-overs done in our signature black. Thanks Gabe for allowing to have our own color! We also did f/r wheel bearings and full alignment.

 
 

JEFF: The team at Z Car Garage began with replacing the poor performing brakes with the complete ZCG Big Brake Kit. With the car now stopping as it should, they next turned their attention to the suspension. A set of front and rear coil-overs were installed on the car along with adjustable T/C rods and camber plates arms and so on. The car was then height adjusted and corner balanced.

 
 
 

Cooling and Driveline Upgrades

On their first visit we changed the spring rates to improve handling and put some friction modifier in diff. At the very end of this visit unfortunately the car was making some strange noises. We suspect the previous builder had starved the engine of oil a few times leading to rod knock. so we send it to Rebello for a rebuild. In spring of 2021 we had made enough power and focused on cooling modifications with a new fabricated a fan-shroud setup.

 

JEFF: With brakes, handling, fuel and exhaust systems addressed, we set out on our second CA Targa event in June 2021. This adventure took us through the CA desert and across the Sierra Nevada Mountains two times. If you live on the west coast you might remember the incredible heat wave with temperatures approaching 115 degrees F. This caused severe over heating problems with the existing cooling system, which made for many unplanned stops along the way. While we did have many great conversations waiting for the car to cool, some with our feet in a Sierra Nevada river, we knew this was unsustainable. Another issue that became noticeable during our second event was the wicked noises coming from the clutch, rear differential as well as the driveshaft. On the positive side of the coin, the car turned, stopped and handled incredibly well and we managed to complete the roughly 1,500 mile event under our own power. We were also able to establish that the car is extremely fast and with that the stock seats and belts were just not quite enough to hold us in place or to provide even the temporary illusion of safety. Woohoo!

 

Next up were the cooling, cold air intake, clutch, rear diff and driveshaft upgrades along with safety and comfort improvements. We installed a new aluminum radiator, rerouted the upper and lower hoses and changed the cold air intake system to reduce intake temperatures. The transmission got an upgraded flywheel. kevlar/ceramic, 11″ 26-spline clutch, new Tilton T/O bearing and aluminum driveshaft from South Bay driveline…the Z was now ready to drive anywhere.

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 200 CV axle kits on customer cars and we are stoked with all of the positive feedback. ZCG CV axles were installed and the rear differential was rebuilt with a new R180 OSG LSD unit, bearings/seals etc.

 
 
 

Dyno Tuning

 

Rob dyno tuned the LS via HPtuners software. It put down a stout 408hp/387tq to the wheels:

 

Enjoy this extended video of Ryan and Jeff’s Z including dyno runs, test drive with Rob and engine/exhaust sounds…volume up!

 

Wheels

 

Wheels make the car and a set of VOLK TE37V wheels from another client project ended up replacing the 17″ Rota wheels the Z came with. The TE’s transformed the car!

 

Details

 

After running a successful Targa event in 2022, the Bartel’s returned to ZCG in 2023 for a small list of improvements including rear hatch body work, installing a BRE type rear wing, minor improvements to the suspension, turn signal/high beam and seat rail repairs along with getting the AC system running more reliably. These are the details we excel at:

 
 

The previous owner left several holes in the firewall behind the evap box, so we removed all A/C components and made a new seal to isolate the cabin from exhaust and heat. In the back, we fixed the rear strut after locating a spacer placed in the coil-overs. With the A/C system sorted, we did hatch seals and pulley/belt on the compressor were all properly aligned.

 

If you are doing spirited driving or long road trips, the Recaro Specialist seat is the best for your Z car! More photos of the interior and roll bar in the galley below

JEFF: To improve safety and hold us in place ZCG installed an Auto Power roll bar with. custom removable harness bar. Rob convinced us upgrade the stock seats to Recaro Specialist seats and 5-point harness system, along with front and rear strut tower braces for increased rigidity. New Hella H4 headlights were also added to replace the original ones that barely worked. Ryan and I had Rob’s team add a 330mm  Momo steering wheel.

 

Exterior paint by our man William, modified rear spoiler some BRE side-view mirrors top the cosmetic changes:

 

Driving is Believing

 

Jeff lives in Central CA while Ryan lives in Arizona. They share this car Father and Son and we get reports from each of them sharing how much they love the car now.

JEFF: With cooling, driveline, safety and comfort addressed and plenty of test miles on the car, we set out for our third CA Targa event in May 2022. This event took place close to home in the Paso Robles wine country. The event was over 1,000 miles, covering many excellent canyon roads. Starting with a 390 mile bonsai run from Phoenix AZ to Los Angeles CA and continuing for up through the central coast of CA. During that time, we beat on the car mercilessly, and the car ran pretty darn flawlessly. Needless to say, third time was the charm, and the trip was a smashing success.

 

The Father/Son duo would go on to successfully complete the Targa California rallies in 2023 and 2024, followed by numerous driving events and gatherings. Each time they were super stoked with the Z…

RYAN: Targa ‘24 is a wrap. Over 2100 miles from AZ to Monterey and back. Some fantastic roads, 2 historic race tracks, endless good times and some of the best people around. That’s Jeff Bartel grinning in the drivers seat. Getting to run the rally’s with him has been a gift. Looking forward to the next one, and hopefully the Targa AZ works out. Gonna start pre running next week.

  
 

RYAN: The Japanese Corvette on the final day of the 2023 #targacalifornia. Over a thousand miles in a long weekend with some great humans, new roads and beautiful cars. The recipe for the car is at last perfect thanks to Rob and @zcargarage. All that and to top it off I get to do that whole thing with my father. Looking forward to the first Arizona Targa this fall.

Thank You!

 

We enjoyed working you Ryan and Jeff. Thanks for you support and keep making memories while Enjoying The Ride in your Z!

Colonel Roser’s 1978 Datsun 280Z

Filed under: 280Z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 2:40 pm on July 24, 2023

 

At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goals reality is our passion. Gary Roser brought his 1978 Datsun 280Z from Monterey, Ca for a full restoration, ZCG-style. Our Z Car Garage Big-BrakesZ Car Garage CV Axles along with a new drivetrain, full suspension and body restoration transformed this S30.

 

Our journey with Gary began 15 years ago and blossomed into a strong friendship. Gary and Rob recall their first meeting:

Gary: “In Oct/Nov 2007, after selling my ’99 Corvette I went online looking for Z Car restoration shops. I called Rob and introduced myself and discussed what he could do for me. Obviously he was very cautious in his response and made no promises. He also stated that he would have to see the car before he would consider taking on the job. My next move was to drive to San Jose and meet him in person. Needless to say I was immediately impressed with his shop cleanliness and the scope of his business. He also impressed me with his no-nonsense approach to our discussions and pulled no punches. Also, as a retired Marine, I noted with some degree of amusement his individual shop uniform. Fortunately for me he gave me a thumbs up, had it towed to his shop and off we went!”

Rob: “Gary came to ZCG when I was very young in my business ownership and asked me to restore his ‘78 280z. We were going to restore it as if Nissan didn’t have a budget. At the time we were really into the C8 Panasport wheels, doing 3L engines, KA24 5-speeds, and suspension work etc. I wanted to build Colonel Roser a car that we could both be proud of.”

 

He bought this Z brand new 1978 and absolutely adores it, being an integral part of his life for decades! Before going into the restoration work let’s take a look at the story behind Gary’s Z and his airborne career…

Fighter Pilot, Z Pilot

 

Gary: “I bought the car on June 4, 1978 at Terry Allen Autos in El Cajon, CA (just east of San Diego). The original window sticker, faded, but still readable: $9543.00. While shopping to replace my wife’s Ford station wagon with a Datsun 510 wagon I saw my black 280Z in the showroom. I needed that car like a hole in the head, as I already had a 1968 GTO convertible, stick shift, with air conditioning, that I had ordered just prior to leaving Vietnam in June, 1968. Anyway, I made an offer to buy both the Z and the 510. It took a lot of sweet talking to convince my wife that it was a good deal! I drove the Z regularly the first couple of years, putting 13,000 miles on in the first year”

 
 

“In February 1980, I received orders to move up the I 5 to MCAS El Toro, and back into a flying billet, flying A-4 Skyhawks. We bought a nice home in Mission Viejo and life was good. Then the winter rains came. We had a two car garage and the Z and the GTO occupied both stalls. It was a hard decision, but I put the GTO up for sale. I took command of Marine Attack Squadron 311 (Call sign Tomcats) in May of 1981. For my birthday, my wife got me the California License Plate: 311 TCATS which remains on the car today!”

 

“In the spring of 1982 I was approached by Jim Lau, the owner of The Foreign Works auto shop in Lake Forest, CA where I had been getting the Z serviced, about installing a turbo on the car. With 48,500 on the odometer, it was turbocharged with about 10 PSI of boost. I finished up my tour in 311, and then received overseas orders to Japan in July 1983. In July 1984 I returned stateside with orders to Washington, DC.  I flew the family and pets to Virginia and then drove the Z across by myself. In 1986, after being promoted to Colonel, I fell in love with the new C4 corvettes, and just had to have one.” Below, Gary with his 280Z and C4 ‘Vette:

 

“After 4 years in DC, we headed back out to California for my final tour as Commanding Officer of Marine Air Group-42, located in Alameda. The Z Car had about 90,000 miles on her and the trip west was a hilarious adventure. As an aviator I was very used to radio communications, so I equipped all three cars with CB radios: I drove the corvette, my 18 year old son drove the Z, and my wife, daughter, and animals were in the OLDS. Needless to say, radio discipline broke down numerous times on the trip. I tried to keep everyone on a discreet channel, but the ladies liked talking to all the truckers. We safely made it to Alameda, and I spent the last two years(1988-90) flying my ass off. I had several squadrons in the air group, including a helo squadron. Not having any helo time prior to then, as Group Commanding Officer, I was able to get a little over 100 hours of helo flight time and  I grew to have great respect and appreciation for their type of flying-it was a great way to finish my aviation career.” 

 

“I retired from the USMC and moved to Monterey, Ca in the fall of 1990 to take a staff position at the Naval Postgraduate School as the assistant Dean of Students for International Affairs. I bought a 1999 C5 Corvette convertible which became my primary driver and while I maintained the Z with regular checks, she sat most of the time. I needed to get rid of one of them and agonized over that decision. The Z car was in bad shape, rust and engine issues, and tired after 113,000+ miles, but my 27 year attachment kept tugging at me, and I just couldn’t let her go. I made the decision to sell the ‘Vette, and started looking into restoring the Z car. And that is how I met Rob Fuller…”


Above: The 280Z prior to restoration in 2007. Let’s dive in to the work…

Body/Chassis

 

We began the restoration process with body and chassis. Gary’s 1978 Datsun 280Z had severe rust issues. Many would have written this car off due to the extensive repair it needed but Z Car Garage and Williams’ Auto Body were tasked with the job of saving it. Photos below show multiple problem areas including frame rails on both sides, lower and upper radiator support, the quarter panel just under the rear quarter windows, door jams and rocker panels on both sides. More photos of the rust repair can be seen HERE.

 

Gary wanted the Z painted black and William worked his magic in 2009. The result was stunning, and remains just as slick to this day:

 

The front/rear bumpers were re-chromed. Following the body repair and paint, PQR-15 was applied to the interior and underside. We bagged/tagged every nut/bolt for plating along with fresh hydraulic lines:

   
Newly plated parts and suspension being mocked up. We love the gold (hydraulic) and silver (fuel) lines against the gorgeous black paint in the engine bay:

 

All front and rear suspension parts were powdercoated with struts/coil overs mocked up. Note additional plated hardware:

 

Drivetrain


Replacing the L28 in Gary’s 280Z is a 3.1L Rebello engine using factory fuel injection. Below you can see how the unsightly stock intake manifold was transformed into a thing of beauty…


Engine bay completed. See more in-progress photos in the gallery below:

 

To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. The KA24 unit is significantly stronger than early S30 transmissions.

 
When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is a Quaife LSD. The R200 houses a 4.11 R&P assembled in-house (by our very own Joshua Corwin). Rounding out the drivetrain upgrades are a set of Z Car Garage CV Axles (shown below)

 
 

The factory EFI was updated with a fuel pressure change and custom tuning of the MAF. Gary’s car ripped, with the 3.1L making 190hp/205tq at the wheels… fantastic for a factory EFI car back in 2007. After driving and initial break-in we performed a valve adjustment and it just shined. It was awesome to see the Colonel driving and enjoying it again!

 

Interior

 

Following the body/paint restoration Gary visited Z Car Garage and he would find interior upgrades on other client/project cars for his 280Z:

“Over the next 5 years more work was done and “upgrades” became a common occurrence. I was like a kid in a candy store-let’s do Recaro Leather seats, power windows, power door locks, and hey let’s do power steering (absolutely love it). And a whole host of other things, including Autometer gauges recessed into the dash which I saw on another Z in Rob’s parking lot of Z’s.”

A complete dash restoration was performed with full HVAC/ducting and A/C refurbishment:

 

Autometer gauges, fresh wiring and re-furbished center console:

 

The power window and door lock conversion with more plated hardware:

 

Recaro Specialist seats in leather are our favorite upgrade to the S30 interior. Gary enjoys modern creature comforts like Bluetooth, back-up camera, power steering and full sound system:

 

The A/C compressor was upgraded to a Toyota unit that we like to use. All weatherstripping was replaced:

Suspension

 

The chassis was treated to a full suspension rebuild with new parts, bushings, Ground Control coil-overs (Koni struts with our spring rates) and ST sway bars front and rear:

 

Z Car Garage Big-Brakes

Gary has our ZCG Big-Brake kit. Not to be confused with our current Z Car Garage Big-Brakes (for small wheels), this Big-Brake kit was our initial setup from over a decade ago. This 328mm sized kit requires 17″ diameter wheels and the massive ST-42 calipers are finished in bright red. We actually did all the R&D in-house for this setup…using a 280ZX master cylinder and our own mounting brackets.


A few more detail shots of the Big-Brakes, they really pop behind the black Panasport wheels:

 
     
 

Since it was in its infancy we did not market or sell this BBK to the public, installing it only on our clients vehicles. There are about 20 sets of these early, 328mm BBKs on client Z cars like James’ Turbocharged L-Series 240ZScott’s 260zGary’s Datsunworks-Powered 240Z and Lou’s RHD FairladyZ:

 
 

Panasport Wheels

 

Gary also got a set of our custom Panasport Racing C8 wheels. These 3 piece, 17×8 wheels allowed fitment of a 255/40/17 tire under stock fender flares:

 
 

When ZCG was starting to build a series of RB-powered S30sRob brought in a pallet of C8 wheels destined for the builds. Gary wanted a set so we hooked him up and his desired black spokes with black anodized lip and hardware. They look great on his Z:

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 200 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

We built Gary a set of CV Axles, shown below:

 

Details

 

The little things are what we excel at. All window trim including quarter windows was powdercoated black at Gary’s request. This general “blacked-out” look was a point of contention:

Rob: “We had so many arguments over it…he wanted everything ‘murdered out’ and I suggested keeping the chrome/stainless, We fought tooth and nail and he always won…Gary outranks me since he’s a Colonel and I’m a civilian.”

The blacked-out theme carried on to many exterior parts like tail light bezels, side marker housings and the Z Car Garage license plate frame…even the white lettering changed to black:

 

The 280Z’s front/rear bumps did remain chrome after re-finishing. Below: More plating and hardware details:


HID headlights. Please check the gallery below for more detail shots, there are too many to list in this blog post!

 

Enjoying The Ride

With the restoration completed, we drove down to Monterey and delivered the 280Z to Colonel Gary:

 

Gary enjoyed driving the Z for a few years. It was hard not to grab attention with this s30…people were intrigued with the wheels, stance and of course that blacked-out look:

 

Gary: “Let me mention here that I get compliments on the car practically every day, many from thumbs up or yelling from cars and motorcycles in moving traffic.  Quite often folks want to see the engine, and when I raise the hood, people remark that it looks like a factory install and are absolutely amazed at how beautiful it is. William’s paint job still looks amazing as well.  I constantly get quotes like ” I used to have one of those, I am so sorry I ever got rid of it”; “what a beautiful Z, I just don’t see them on the road anymore”.  Best one though, was “Yes, I had one until one night I wrapped it around a tree and almost killed myself, but it was my favorite car”.  And when I tell them I am the original owner they are blown away.”

 

We attended several shows including the 2013 ZONC Annual Car Show in Brisbane, Ca and 2013 Silicon Valley Auto Show in San Jose:

 

In ~2015 a persistent electrical issue was traced to the wiring harness which led to an unorthodox (but exciting) solution:

Gary: “I was frustrated after the electrical problems. Rob explained to me we had to use a 1978 wiring harness to make everything work.  As I recall we changed out 3 wiring harnesses and even sent the computer module to San Diego to be reworked. Rob actually went to the Central Valley and purchased a 280Z for parts, so as to get another wiring harness. At that point I was thinking of other options and approached Rob about doing an engine swap, but that is a story for another day! “

Rob: “We located an unmolested harness and still couldn’t get it sorted. Colonel said ‘I love this car, but since we can’t solve this gremlin I want to do something different with it’. Years ago we were not into V8 Z cars until the LS-based engines came around. Perfect power delivery and balance…it just works in Japanese (and other) platforms. We had done Ben Sutton’s LS-powered FD RX-7 and it worked really well with incredible torque. The Colonel talked us into it… ‘There’s two loves in my life: I love my corvette and I love my Z car.’ We had to bridge the two together for him.”

LS3 V8 Power

 

Gary:  Well, after three tries I just didn’t see a way forward with the Nissan motor, and asked Rob about doing a V-8 conversion. He had not done an engine swap, so he was cautiously optimistic about trying one. In his typical attention to detail fashion, he did a lot of research, found a way forward, and off we went.  Lots of growing pains, and a few curve balls, but the end result has been spectacular!”

Rob: “We did an LS3 swap, our first V8 S30 conversion ZCG performed start to finish. Super proud of it. There were some initial teething issues: a larger twin-fan radiator eliminated cooling problems and our upgraded ZCG CV Axles solved axle issues. We de-tuned the LS3 to give the Colonel a Z car that is fast but but also reliable.”

The LS3-crate motor came with a warranty from GM and weighs less than the L-Series engine it replaced. Engine and 6-speed transmission were installed using the Hoke Performance kit:

 

The larger, twin-fan radiator and A/C plumbing and wiring:

 

Ovalized exhaust from headers to catalytic converter help with ground clearance:

 

Dyno Tuning

The LS3/6-speed T56 drivetrain was dyno tuned after installation, making 405hp/410tq at the wheels, a significant increase of 115hp/206tq compared to the L-Series:

 

Enjoy this video with dyno run, in-car driving, cruising and fly-by action with Gary’s LS3-powered 280Z:

 

We love how happy Gary is with his V8-powered Z:

Gary: The car is an absolute gas to drive. I will tell you up front that it is not a refined ride. The suspension is tight and pretty stiff, but gives you great road feel. The T-56 6 speed transmission, mated to the LS-3, required some getting used to, but is solid and efficient. The turning and maneuvering capability of the car in its two dimensional environment is terrific. It reminds me of when I did aerobatic maneuvering in the A-4 SkyHawk! What can I say about the power and torque the engine puts out-405 HP at the wheels!”

 

“I have had my way with a lot of other fast cars, and even a motorcycle who tried to take me on, who have no idea what is under the hood of my little Z Car. (Sometimes the wide tires give me away!)  Best acceleration is in 2nd and 3rd gear.  I don’t like to take it much over 90 mph, because the front end gets a little lifty. (I have over 4000 hours in fighter and attack aircraft, and I know what lift off feels like, so I don’t need to get airborne again!)”

Thank You Colonel Roser


Rob: “We have so many great stories with Colonel Gary. He’s more than a client, somebody we really admire and look up to. Such a fan of his. My father was so proud to be a Marine and Colonel understood this with his Military background.”

 

Gary: “I will be 81 in May and I don’t see another adventure like this one in my future so let me comment about Rob Fuller and his Z Car Garage. We have been friends now for 15 years. We have been on this journey together, through all the ups and downs and twists and turns. He has been there for me every single time, night or day. I just can’t imagine there is another car guy out there who would have had the compassion and understanding to shepherd me and my Z Car through this adventure.”

Below: Colonel Gary Roser and Rob on May 23, 2023

 

“Over these 15 years I have watched his business expand and grow, and am amazed at the breadth and width of his knowledge and his reputation in the auto industry. His leadership skills and the way he runs his shop is suitably impressive, and he has good people working for him.  And, by the way, he is a pretty topnotch driver as well. With him at the wheel and aggressively putting my Z Car through its paces, I am reminded of my fighter pilot days when I could fly an airplane like he drives my car. In another time and place I would have been honored to have him fly on my wing.”

Enjoy The Ride Gary and Long Live The Z!

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!
