This is Christopher’s 1975 Datsun 280Z featuring our Z Car Garage CV Axles, Z Car Garage Big-Brakes and ZCG KW coil-over suspension! He performed a meticulous restoration himself with highlights including an ITB EFI-fed L-Series, CD009 6-speed transmission and Watanabe wheels. Let’s take a look at how Christopher got into Z cars…

 

CHRISTOPHER:  The previous owner of the Z lived less than a mile from our house. I noticed it in his garage one day on the way in to work and immediately went by that afternoon to ask him about it. It was bought new in his family and given to him by his Uncle. It hadn’t ran in over five years and he was hoping to get it back running. I asked him almost every other week for about a year to keep me in mi d if he ever decided to sell it. He eventually moved for work and was forced to sell the car…

 

…My wife was the first to tell me and I was pushing the car to our house that afternoon! I got the car running after a few months and drove it stock for a year or two. After moving down south and the car being exposed to high humidity, I decided to restore the car and take care of the body before things got out of hand. What began as a tear down to have the car repainted, turned into a full nut and bolt restoration that overall took just under six years to complete.

 

Drivetrain

 

Christopher’s fanatic attention to detail really shines in the super-sanitary engine bay. The stock L28 uses Jenvey individual throttle-body fuel injection (MegaSquirt ecu) with parts from Datsunspirit and ProTunerZ. He made a mount for the IAT sensor, installed @fuelinjectorclinic injectors, @robsperformancemotorsport fuel rail, and @radiumengineering bits (fuel pressure regulator, gauge, and two petcock drain valves for the catch cans). More photos in the gallery below!

 

CHRISTOPHER: The goal of the build was to highlight and improve what was already great about the car. I wanted the appearance, weight and simplicity of a 240 with the drivability, performance, and rigidity of the 280. I was inspired by GT3s and similarly was seeking to build a light weight, naturally aspirated car with ITBs and and a quality exhaust. The car now weighs 2400 pounds and I wanted to ensure only quality items were installed (OEM or better).

 

Below: At Moore Performance dialing in the ITBs. Chris plans to re-visit the dyno to squeeze more power with a different CAS sensor.

 

The exhaust includes a Z-story header and custom piping fabricated by Tyler Dorsey. Below, also visible are T3 coil-overs, LCAs, and Z Car Garage CV Axles:

  

Z Car Garage Big-Brakes

  

CHRISTOPHER: I heard about ZCG from various Datsun Forums before I purchased the car. Rob and ZCG were known for their passion with the S30 and the research and development that went into every product offered. I chose ZCG for the lower control arms, brakes, suspension, and coil overs because I wanted a cohesive setup that was developed in a way that ensured every component worked in harmony with each other and improved the S30’s driving characteristics, not change it.

  

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 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 retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

 

  

CHRISTOPHER: Early on I considered more outrageous options that were popular within the community. But after researching those companies, and the reviews of their products further, it became clear that was not the direction I preferred to take. A lot were over engineered and under tested, over complicated, or unnecessary. Ultimately, I chose ZCG after numerous conversations with Rob where he spent time breaking down his own personal opinion and the shop’s research to highlight where other options may over engineer products to the detriment of the car or may not unlock the full potential of the chassis. I liked that he was honest with what he thought was worth upgrading and what wasn’t necessary. It was obvious he cared and wasn’t out for just a profit. He lives these cars.

 

Big-Brake Kits Available For DIY Install!

Z Car Garage is proud to offer our Big-Brake Kit to Z-Car owners that want to perform the installation themselves. We can ship worldwide and each kit contains everything needed with a comprehensive installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Christopher’s beautiful S30 and his ZCG Big-Brake installation:

 

CHRISTOPHER: The installation was a breeze. Uniquely for this project, Rob and I talked early on (almost five years ago) about testing ZCG’s ability to develop and deliver products beyond the west coast. We began this venture as a means to begin testing the various elements of that process logistically. For this, Rob also wanted to demonstrate how ZCG was capable at recommending, assembling, and shipping complete components to the point that it removed much of the work and guessing from the consumer. Rob’s hope was to prove that if someone wanted the complete setup (engineered and proven by ZCG over years of experience), a customer could essentially order the catalogue and receive a complete solution delivered to their front step. That’s exactly what happened with this.

 

Our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake function. Chris successfully installed the BBK on his Z and they look great behind the 16×8 (zero offset) Watanabe wheels with 225/45/16 Toyo tires. Beyond ease of installation and quality components, our Big-Brakes perform by offering superb pedal feel…everyone that drives our demo Z confirms! This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments.

   

CHRISTOPHER: The car feels planted like never before. Our family also has a fully restored 73 240 that is an excellent OEM example. Where that car feels stable and drives well, there’s no denying the age of its component and it drives like a seventies sports car.  The 280 feels like a modern sports car and inspires confidence. The brake pedal communicates exceptionally well and the balance of the calipers bring the z down from speed a rate well beyond most cars today. The light weight of the S30 and the size of the ZCG big brakes is an unreal combo!

 

Z Car Garage CV Axles and KW Suspension

  

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. Christopher’s ZCG CV Axle set, #0457 installed by himself:

 

Detailed shots, note how clean his work is!

CHRISTOPHER: Not only does ZCG already provide extensive installation guidance (70 plus pages of instructions for the brakes alone that cover everything from torque specs to bleeding procedures), but, for this, he assembled and shipped each corner fully assembled (spindle, wheel bearings, coil over, and camber plates). I was able to install the whole assembly into the strut tower, the lower control arms, and attach the brake lines and the corner was complete! Having this work done by Rob not only saved me time, but also gave me the piece of mind that these critical pieces of the chassis were done right and by someone with decades of experience. From there it was installing the ZCG CV Axles and I was then off to the remainder of the build.

  

KW x Z Car Garage Coil-over Suspension

 

Christopher installed our KW V3 suspension, complementing the ZCG Big-Brakes and CV Axles nicely. Details on our ZCG KW V3 coil-overs will be covered in a dedicated blogpost coming soon.

 

CHRISTOPHER: The KW V3s offered by ZCG are the most valuable investment I’ve made in the car (and I’ve replaced nearly every bolt on the car at this point lol). Nothing has affected the performance and drive of the car as drastically as the coil overs. The Z is smooth on the highway and is able to carry momentum through corners like never before. I can’t wait to get it out on the track this spring. Couldn’t recommend them enough. Wether it’s the brakes or the suspension, ZCG has formed relationships with the partners that matter and have a proven track record in the auto industry. There’s nothing else like it period.

 

Interior

 

Chris’ phenomenal work extends to the interior where original surfaces were refurbished or replaced with OEM parts.

CHRISTOPHER: I chose to put the original luggage riser vinyl back in as I really like the original small diamond pattern better than the newer options. Also installed the rear quarter panels I bought off @sportzwerks and refurbished which never came with the car. Feels good to be bringing it back better than it was. Pretty cool to see the refinished dash frame from @vintagedashes  in the car as well as the dash cowl with @speedhut gps puck installed. The 6-speed shift knob is from @thedavemason:

 

Enjoying The Ride

After a long journey Christopher is driving his Z! Follow his build on Instagram and see it in action in the video below, volume up!

 

CHRISTOPHER: Moving forward I plan on getting the z out to meets and on the road! It’s going to be driven! I found a lot of the suppliers that helped with Nissan’s heritage program when the 350Z was released, and took the time to create what I hoped to be a quality build that maintained the character of the S30s with components that not only perform but will last another 50 years. The result isn’t blistering speed but a visceral driving experience in a truly timeless car.

 

Thanks for your support Christopher we love that you are Enjoying The Ride and Long Live The Z! More photos in the gallery below.

Joseph L recently took ownership of our shop’s 2023 Nissan Z. Before we dive into Joseph’s story, let’s give the RZ34 a proper send-off by chronicling Z Car Garage’s journey with Nissan back in 2021…

From Prototype to Production

  

Our journey with the new Z began in May 2021, when Nissan invited us to their Headquarters in Tennessee to get up close and personal with the Z Proto. We thank Dan Passe and Jonathan Buhler for bringing ZCG along for the ride. We were fortunate to be a part of a series of great events since this inaugural visit.

In August 2021 we were invited to attend the 2023 Nissan Z Global Reveal event in New York:

  

In September 2021 we were guests of Nissan at SEMA:

  

In October 2021 we hosted a 2023 Nissan Viewing Event at Z Car Garage for the public to enjoy:

 

In June of 2022  Nissan kindly lent us a 2023 Nissan Z for five days

 

For Monterey Car Week in August 2022, Nissan gave us a 2023 Z in Ikazuchi Yellow:

  

Yes, Nissan even lent us an RZ34 to be Pace Car at the CSRG Vintage Races and on display at the Velocity Invitational in 2022!

  

We eventually took delivery of our own RZ34 in 2023. This is a 6-speed manual, Performance trim finished in Black Diamond Pearl with Graphite Leather interior. Read all about our experience HERE.

 

The fun didn’t stop there, after receiving our RZ34, Nissan invited us for a 3-day adventure along the Pacific Highway in this Boulder Gray Z:

 

Hooked on the Track: Joseph’s Infiniti G37 Sedan

 

ROB: We met Joseph in 2022 when he had another shop install a supercharger on his G37. There were many things that didn’t work well and he had us resolve them. Once we sorted out this car for Joseph he was really enjoying it and started modifying further. Then he discovered track days, picking up the pace and loving his G37 on road courses.

 

JOSEPH: My journey to Z Car Garage started with a second-hand, unused Stillen Supercharger kit for my 2010 Infiniti G37S sedan. The installation had problems. At this point I’d never heard of a “track day”, so if you’re wondering why I’d buy a supercharger kit, I ask myself the same question. I needed help. I found Z Car Garage. While the repair was being quoted I read Z Car Blog, and figured out that I had stumbled on the top Z shop in the world, in my backyard.

 

When I first met Rob, I will never forget, he was shuffling through files, looking for mine, while signing along with The Doors–pretty loud and pretty good–but he was replacing choice words with “Z Car Garage”. “Z Car Garaaaaagggeee, is calling us”. Z Car Garage not only fixed my beloved G, but they made it Z Car Garage Style. It was a rocket. I would later learn the term “sleeper’. It was the best sounding car I’ve ever heard, like naughty angels having a good time. The only other car I heard with this sound was a 370Z in San Jose that must have been set up the same way.

 

ROB: We started discussing future upgrades when unfortunately the G37 was stolen from his driveway, all captured on video and leaving him heartbroken. A few days later the car was recovered, but not salvageable. Joseph was in a tough spot. While the G37 is a wonderful car, we considered alternative track day cars, like a 350Z or 240Z and then a lightbulb moment…what about the Z Car Garage #49 RZ34! 

  

We were ready to sell since it was sitting idle and not being driven as much. There simply was not as many RZ’s around as we hoped to justify it as a development car. In the two years of ownership we did enjoy it at the track, attending local gatherings and driving events like the Breakfast Club Rally’s Tokyo Calling. It was time to pass on the torch and Joseph was the guy.

 

Long Live Joel Anderson and #49

 

Shortly after taking delivery of the new Z we knew exactly how we wanted to make it special, and that was to honor Joel Anderson’s #49 IMSA GTU Datsun 240Z. The graphics were laid on via wrapping and vinyl decals affixed for the numbering/IMSA stickers:

 

JOSEPH: Rob introduced me to “Hooked on Driving”. Being allowed to drive on real race tracks was a revelation, and I was “hooked”, instantly. After my first track day, we installed a Z Car Garage style suspension. I did three more track days, then the car was stolen. My heart was so broken that I thought about buying a beater and giving up the sport, for six or seven seconds. At this point I am in a simulator most mornings, practicing, so my priorities had changed. I wanted a Z.

 

When Rob offered the shop Z, I did not think about it. I was not even 100% sure which one he meant, nor did I care. It’s like Jimi Hendrix offering to sell one of his guitars. But it was the new Z, with the 49 car livery, a tribute to Joel Anderson. It still chokes me up as I write this that I am entrusted with the livery. Anybody that asks about the car gets a speech about Joel , Z Car Garage, and the 49 car. After one such occasion, the person asked “so, did they sell you this one for a dollar??”. No-I missed that bargaining chip when I had the chance!

 

ROB: Coolest thing of all is that Joseph knew the story of Joel Anderson, and asked us if he could carry on the livery and share Joel’s story. Such a win/win. Joseph has done several track days and gives us great feedback so we can continue developing the RZ34 platform. Thanks Joseph, looking forward to seeing you more and upgrading this Z to see more checkered flags!

 

Track Preparation

When we acquired our new 2023 Nissan Z the very first modification was a Fast Intentions TDX 2.5″ Cat Back Exhaust System. FI makes the best exhaust for late model Nissans/Infiniti sports cars, If you have an RZ34 this is the one to get with high quality, great fitment and a wonderful exhaust note.

 

The Fast Intentions Cat Back exhaust system also provides solid power gains. We performed before and after dyno runs on our 2023 Nissan Z Performance 6MT and saw 388hp/392tq with the OEM exhaust and 399hp/394tq with the Fast Intentions exhaust. Expect even more with tuning, see more photos and exhaust sound video in our product review Fast Intentions Product Review.

 

Before  Joseph’s first track day at Laguna Seca in the #49 RZ34 we installed the following parts, with more installation photos in the gallery below:

KW V3 Coil overs

 

Stock and KW V3 installed:

 

SPC Front Control Arms and Whiteline Sway Bar Set:

 

Nismo Cold Air Intake

 

Yokohama Advan Neova AD09 tires, Front Brake Pads (G LOC R8), Rear Brake Pads (G LOC SG1), Stoptech brake fluid 600f and Stainless brake lines:

  

We received great feedback from Joseph after his Laguna Seca track day (in-car video HERE)

JOSEPH: It was lowered an inch. It handled beautifully! It was very balanced and grippy. It barely understeered. I think most remarkably, going over the hill at turn 1 felt easy, whereas in my G I felt like I was weightless and I was going to lose it. I have learned that the size, weight, and center of gravity of a car are more important than the engine. That said, power delivery was super smooth and there’s a lot of it. You don’t really feel the turbos engaging, it’s just more power. The engine still has the stock tuning and I am still fine with that. The brakes are going to get an upgrade. They performed great but by the end of the day they were pretty cooked. I think we also want an oil cooler as that got pretty close to the red, but I never lost power.

 

What’s next for Joseph?

JOSEPH: I view myself as the sponsor of the car, and the luckiest test driver on the planet. Z Car Garage is the engineering staff and mechanics. Rob is the technical director. We can build the best street-able track car on the road, as Rob sees fit. I will keep working to get better as a driver and push the car as Zs are meant to be.

 

Long Live The Z!

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-Brakes, Z 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:

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.

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!
