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…

 

 

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!

Our Z Car Garage Big-Brakes and Z Car Garage CV Axles continue to win over Z-car enthusiasts locally and globally. Elmo P recently purchased a set of both for his 1972 Datsun 240Z and had them installed himself in SoCal. Before we go into the installation details let’s take a look at how Elmo got into Z cars…

ELMO: In 2005, I decided to sell my first 240z, a 1973 which I owned for almost 17 years, and the car on which I learned almost everything I know to this day about wrenching. I felt I had outgrown the Z and it no longer fit in my life. However, immediately after the sale, I felt sick to my stomach for weeks and never really got over its sale. Over the next 13 years, I would periodically search for a replacement 240z, only to find out prices had skyrocketed and I could no longer afford one. Fast forward to 2019, I was now ready to resume my search. I found a 1972 240z that had been meticulously cared for by its 2nd owner of almost 47 years. The car was mostly stock, minus the addition of an L-28, and Panasport wheels. 

My goal was to modify the car tastefully, with modern components where needed to increase driving pleasure, yet leave the classic body-line largely unmolested to not disturb or detract from the design’s natural beauty. Over the past 4 1/2 years, I’ve made modifications to every area of the car and I can finally say that I’m at about 95% of attaining my vision. As mentioned previously, Elmo wanted the body to remain mostly unchanged. The only additions have been a front grill and spoiler from Star Road in Japan, front bumper delete plates from Skillard, one-piece rear bumper, and Euro tail lights and front turn signals. Wheels are Volk TE37V, 16×8 +0, and 16×8.5 +10 with Toyo R888R tires in 245/45/16.

Interior

ELMO: The interior received many upgrades including Recaro seats, Speed Hut gauges, re-upholstered door panels, tranny tunnel, and rear shock towers, billet pedals, new dash cover and a Sparco steering wheel. However, one of my favorite modifications is that of cleaning up the rear shock towers by removing the old vinyl covering and plastic caps, and smoothing off and painting the tops of the towers, along with the addition of aluminum cover plates and new covering on the towers.

 

Drivetrain

ELMO: When I bought the car, I knew the drivetrain and suspension would be my main focus area and hence, the area where I would divert most of my modification funds. All suspension component upgrades are from Techno Toy Tuning., including adjustable coilovers, control arms and diff mustache bar. Gear shifts are handled via a rebuilt close-ratio 5-speed from a ZX which transmits power to a 3.9 OS Giken LSD. Although the L-28 that was in the car when I purchased it was recently rebuilt, my goal was to replace it with a larger displacement street/race engine to increase the fun-factor. After months of searching for a reputable L-Series builder, I came across a renowned Datsun engine builder by the name of Jeff Winter at Rallye Sport in Westminster, CO.

For my mostly street driving application, we decided on an L-28 bored .080 over, forged rods and flat top pistons, and one of his special cam grinds on my car’s original E88 head with a mild street port, all resulting in just under a 3.0L. Induction is handled by triple 44 PHH Mikuni carbs rebuilt by Taka from Kyusha House.

The exhaust is scavenged via a custom-made header from a small shop in Japan, fabricated bu Humble Engineering with a  2.5” straight pipe terminating into a 3-chamber Flowmaster. Below, also visible are T3 coil-overs, LCAs, diff brace and Z Car Garage CV Axles:

Z Car Garage Big-Brakes

 

ELMO: Although my new engine makes more power than the original L-24, and the stock brake system and half- shafts likely within their operating limits to support the increased power, I felt now was the time to make those upgrades to mitigate any future performance or drivability issues. Enter Z Car Garage. I had been following ZCG for a few years and knew that Rob was very well respected in the Datsun community, and offered many products to enhance the performance of the S30. I wanted to upgrade to rear disks, not just for better overall braking, but also for aesthetic reasons.

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

 

ELMO: In other words, the look of drum brakes sitting behind my new wheels just wasn’t cutting it, at least not in 2023. There is no shortage of aftermarket (AM) brake kits for the S30; however, after speaking with many owners who installed AM kits, they all shared one thing in common: No one seemed to be fully pleased with their performance. Most kits are sort of a “Frankenstein” collection of parts which often required different brake boosters, proportioning valves and other mods just to make them work somewhat effectively. In addition, most AM brake kits either did not come with a parking brake, and if they did,  functioned poorly.

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 (40-page) installation guide. Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE. Elmo’s beautiful S30 and his ZCG Big-Brake installation:

Our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake function. Elmo successfully installed the BBK on his Z with and they look great behind the Volk TE37 wheels. 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. Elmo shares his feedback after replacing his existing brakes with the ZCG BBK:

 

ELMO: I contacted Rob to secure a set of his brakes but he advised me they were on backorder but that they’d be worth the wait, so I committed. Due to Covid supply chain issues, the wait was almost a year long, but as the saying goes, “some things are worth the wait”. I finally received my brakes and can confirm that aside from looking great, they meet or beat my performance expectations. Braking is effective, predictable, and confidence-inspiring. However, the best part is that there are no tricky performance issues that you have to figure out as they were designed from the ground-up for the S30, while still utilizing the stock brake booster and other components. All you simply have to do is install them as directed and you’re good to go. Oh, did I mention the parking brake works great!

Z Car Garage CV Axles

 

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.

ELMO: Now that the brake department was taken care of, all that was left to replace is the Achilles’ heel of any S30 with a much more powerful engine, the half-shafts. I had issues with them and their U-Joints on my first 240z which had a 3.0 and I felt that my current Z would benefit from an upgrade. Again, multiple AM options to choose from but given the research and quality of the ZCG brake kit, I felt the CV axles that Rob offered were the logical choice. The axles are beautifully machined and more than robust enough to handle my new engine’s power. I installed the axles myself and have noticed less clunking and vibration, and an overall smoother drive.

Elmo’s ZCG CV Axle set, #0446 installed:

What’s in store for Elmo’s Z?

ELMO: So, what’s left? Well, there’s a few odds and ends but nothing major, at least not until Rob introduces the next upgrade. I’m a firm believer that most of us never truly finish modifying our cars because they are like an ever-evolving canvas of ourselves.

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

We met Kevin E through our client Randy Jaffe out in Georgia. Kevin was here in the Bay Area, Ca for work and wanted Z Car Garage to give his 2008 Nismo 350Z some love. We happily obliged by adding KW suspension and maintenance to an already superb supercharged platform:

KEVIN: I heard about Z Car Garage from a local friend, Randy Jaffe. I met him at Z Nationals down here in Georgia a few years back. Randy kept mentioning Rob when talking about his Nissan and Datsun collection, and after seeing  Larry Chen’s videos about Z Car Garage I had no hesitation about Rob working on the car in the future. It’s funny because I was DM’ing Rob on IG about the car before pulling the trigger to ship it there in our earlier conversations!

History

Kevin is the original owner of chassis #1508. He wanted a manual car to drive and found the Nismo sitting in a lot..

KEVIN:  This was when the 370z and R35 came out. The car I ended up stalling in the parking lot is the same car you see here today. Purchased new in 2010 and was my first manual car. It will always have a special place in my heart because my father taught me how to drive manual in it. 

It’s truly been a car I’ve done everything in from my NASA events, first car I’ve taken to the drag strip, road trips including the drive up from NorCal back to Arizona, enjoying Zcon at Nissan USA back in 2018, and of course the rabbit hole of turning a vision into reality. There have been ups and downs, but the extraordinary experiences and people I’ve met along the way have made it all worth it.

Suspension

We addressed the suspension to attain Kevin’s overall goal of making his Z a double duty car: one that you can get groceries in and enjoy track/canyon driving.

KEVIN: Rob and the team did a full suspension refresh with KW V3s and the full SPL catalog. I’ve held off on it for quite some time because I didn’t feel the actual suspension was worn out or my skill level had surpassed the balance of the OEM ones. He also performed one hell of an alignment, which felt great the whole way back to Arizona. Taking it up the canyons driving through L.A., the car was a blast and Rob absolutely nailed the feel I wanted out of the car. The car was more communicative and had no more body roll! I felt way more confident pushing the car harder.

Full alignment service in-house at Z Car Garage:

Details

The small things are what we excel at. The interior was spiced up with some red Recaro RSG Japan seats to match the original Nismo theme:

KEVIN: I wanted someone that could roll the rear fenders without cracking the paint and handle small dents from the years. Been through paint and body work and wanted it to be done right from the beginning. After seeing the restoration of Randy’s BRE Datsun 240Z following the Daytona accident, I know the car would be in great hands. During my time in NorCal working, I had Rob install a set of JDM tail lights, which I was on the fence about. They came out fantastic and love how they compliment the whole car:

The Tomei titanum exhaust was replaced at Kevin’s request with a custom built Soho system. Tomei below:

New Soho exhaust, with more photos in the gallery below:

Maintenance

The last piece to address was maintenance (fluids/pads/supercharger belt check) and ensuring that the Zcar was ready for its voyage back to Arizona and later Georgia:

KEVIN: What fascinated me was how in depth Rob was with the car. Handwritten notes, small details during the install, and extra care taken during the whole process. That is why I have Rob listed as Dr.Datsun because he truly does take each car in, assesses anything that might need to be addressed, and everything else that the client wants to achieve just like a true doctor!

Vortech Power

 

We put the Z on our dyno for a health check, making a stout 491hp/356tq to the wheels:

Enjoy this video of Kevin’s Nismo 350Z on the dyno!

Driving is Believing

Rob and Kevin discussed ideal suspension settings and the result was a balanced car:

KEVIN: The Z feels so good. As soon as Rob gave me a ride, I could immediately tell. The back end was so planted taking a corner on Rob’s test track, lol. It wouldn’t kick out like it did on the OEM Nismo suspension taking the roundabout corner even with a Nismo GT Pro LSD. Just the right amount of stiff, but also very compliant soaking up the bumps like a cobblestone surface. Rob truly is a magician with suspension, evidenced by his driving background. Before the suspension, it just felt a little dull and sluggish in response.  After having more seat time in the car, it just feels very connected and direct.

We knew that Kevin wanted a bit more feel, without sacrificing comfort and decided to use poly bushings in the suspension for street use.

KEVIN: Driving through LA, all the bumps were not as harsh as I thought and when the road was smooth, it was like silk, but you could feel the changes in the road surface through the steering wheel. I’m glad I listened despite me wanting to put Clubsports on the car. I spoke to a few people that had Rob install the same setup and they all had nothing but positive feedback. Rob takes his clients in steps rather than large leaps not only to get acquainted with the car again, but also to improve as a driver and become more confident. 

Enjoy The Ride

While he was out in NorCal, we were lucky to see Kevin Enjoying The Ride at local events like the ZONC gathering ZONC Gathering:

KEVIN: All the videos I’ve seen of Rob, he just has so much passion in what does! I thought I was OCD about my car, but Rob is such a perfectionist and wants it to be more than 100 percent when the client picks up the car. It not only has the power, but has the footwork now, which was the missing piece of the puzzle. On a side note, Rob has not only been another caretaker of my Nismo, but he has become like family to me along with the rest of the team at Z Car Garage. Rob, I want to personally thank you again for all the advice and life advice you’ve given me during my stay there! I’m eternally grateful for everything!

Kevin’s Nismo 350Z came out really nice and we love his passion. Icing on the cake was seeing him so stoked on having his Z worked on by Z Car Garage. Thanks for letting us be a part of your build. See more of his Nismo Z33 on Instagram and LONG LIVE THE Z!

Our Z Car Garage Big Brakes have been winning over Z-car enthusiasts locally and globally. Jason purchased a set for his 1974 Datsun 260Z and performed the installation himself. Before we go into his Big-Brake experience let’s hear his Z-story…

JASON: “I first heard about Z Car Garage by following Larry Chen’s 240z build on his YouTube Channel. I saw his various interviews with Rob Fuller and was really impressed with his knowledge and passion for the Datsun 510 and s30 chassis. Quickly, I started researching more about the pain points of the s30’s, and noted the lack of support from many other companies in the area of suspension and braking locally. The kits available were Wilwood, Endless, Star Road, among others. No complete kits that were torture tested and raced like what Z Car Garage was doing with their ZCG CV Axles , Brake Kits and other components they were selling. Research and development are key to me, and I was thrilled to see ZCG taking this on themselves. In addition, Rob is a real human being who’s on top of answering questions via email and in person at Z car events. That’s a HUGE deal to me, and it’s so rare to meet someone that of course is just as passionate about his cars as the enthusiasts building them.”

“My 1974 Datsun 260z is an Early model s30. When I purchased it, a few years ago I quickly removed the stock seats and reupholstered Recaro LX vintage seats in Black. I loved the netted headrest, and the clean recaro stitching at the center of the seat. I also removed the Greddy Oni wheel that was originally in the car and swapped it out with a new old stock Nardi Nismo Deep steering wheel with a Black and Gold finish. I went through the interior and purchased a NOS Datsun center console, and replaced the stock door cards with Skillard flat cards with leather pull straps.”

“In addition to the door cards, I added Skillard powder coated heel plates. The car came with BC adjustable coil-overs and Swift Springs which I will be updating in the near future. The BC Coilovers are perfectly fine for the street applications I’m using the car for currently. My suspension underneath the car is the full T3 catalog including the power cradle, control arms, bushings, and even their steering elements. It’s finally sorted, and I really enjoy driving the car the way it currently feels.”

“The car is equipped with a L28, ZX 5 Speed transmission, and 44pHH Mikuni triple carbs built by Taka at Kyusha House. The header and exhaust system are Fujitsubo Legalis R. The engine has since been updated in every way from the ignition system, oil pump, spark plug cables, and brake new seals and belt. The oil pan was replaced with a Moroso baffled racing pan with higher oil capacity.” 

 

“I have two sets of wheels and tires for the car. One set is Volk Racing TE37v custom gold 15×9 at 0 offset on Toyo Proxes R888 205/50/15, and the other set is Work Racing Equip 03 15×8.5 at -3 offset custom bronzed lip, and Gold Center on Falken Azenis RT660 205/50/15. The front bumper is a carbon MSA, and the rear tail light bezels are carbon fiber made by Vintage Carbon. The wing is a Carbon Fiber BRE spoiler.”

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. Jason shares his feedback after replacing his existing Wilwood brakes with the ZCG BBK:

JASON: “The Stoptech ZCG Big-Brakes are really a solid kit. The lead time was pretty rough, but again Rob reassured me every month over the course of a year of waiting that it would be worth it. He was right! These brakes do not disappoint. Once the kit was completely bedded and broken in, I quickly put the brakes to the test on Angeles Crest highway here in Los Angeles. I know this road well, and that’s where I usually push the car at a safe limit, and see where the pain points lie. The ZCG brakes are worth every penny. They are precise, they are confidence inspiring, and also feel great under late braking situations. I had a blast carving around the canyon knowing my brakes would safely hold up. My next test would be to get a couple of track days on them, and see how they hold up under extreme conditions and multiple sessions.”

 

“The goal for the 260z is to refine my current setup. The paint is a bit rough since it was a garage paint job, and I would love to repaint the whole car including the interior. At the moment, I’m building a high compression 3.1L stroker motor with Jenvey 50mm ITB being managed by a Haltech Elite 750 stand alone ECU. My goals long term are for big power, but with street car reliability. I would love to confidently do a track day, but also be comfortable driving my wife to car shows, and even to grab a cup of coffee together. The engine has a custom designed valve cover designed by myself, and commissioned to be created by BSpeed in New Zealand. Big updates to come in the new year!”

Following that initial visit, Mike added R34 GT-R Seats, and a sweet set of Volk Racing TE37 SL custom gloss black wheels (18×10.5 +15), wrapped in Michelin PS4S tires (265/35/18). A Haltech IC7 digital dash was added to monitor vital engine parameters, tying into the CAN box of Elite system:

Add More Boost

Mike was happy with the upgrades we made but like many of us the desire for more power inevitably hits:

“The car has been running flawlessly and the goal with these mods is to support the addition of a single turbo kit that ZCG will be installing this August. The turbo kit consists of a Full Race Twin scroll T4 manifold that will be mated to an EFR 8474 turbocharger. Twin Tial 44mm external wastegates will bleed off the excess exhaust gasses.”

Mike’s R32 came back to ZCG in 2022 for a few more items including:

ATS Carbon twin disk clutch (shoutout to @wubbs18)
New oem timing belt and pulleys
PRP alternator kit
Kansai Service Towhook
OEM Valley cover powder coated with R34 ornament plate
Mines Alcantara shift boot, parking brake handle and boot

Dyno Tuning

Several dyno tuning sessions were performed during the upgrade period. 515hp/437tq on 91 octane was achieved with significant mid-range gains:

 

Mike was pleased:

“Big thanks to @zcargarage for seeing this project through to the end and making the car come to life. We had a lot of headaches and setbacks over the past 11 months, but they did an incredible job end result speaks for itself! Couldn’t be happier. 🤘”

E85 Fuel

“Ethanol delivery is handled by a full Radiumengineering fuel system. Fuel hanger surge tank using twin 525lph to feed the rail and a 340lph to feed the hanger. All new hoses with a -8 feed line. Radium fuel rail with Rail mounted adjustable fuel pressure regulator. All feeding Injectordynamics ID1700XDS injectors. Haltech Flex fuel Sensor and Bosch Fuel pressure/temp combo tied into Haltech Elite to bring it all together.⁣”

On the dyno with E85 the R32 put down 624hp/479tq at the wheels, and Mike continued to enjoy the car:

“So the car has been on flex fuel for a few months now. Made 600 whp and 480tq. Still just keeping the boost around 20psi. Tons of room left in the setup. Been enjoying the shit out of the car is it currently sits. Maybe some minor cosmetic stuff in the near future, but for now….just drive.”

Enjoying The Ride

We were happy to see Mike Enjoying the Boost and spotted his R32 in action at the Tokyo Calling and Breakfast Club Rallies in Northern California:
