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. CJ shipped his 1971 Datsun 240Z from Durango, Colorado for final mechanical sorting, ZCG-style. Our Z Car Garage Big-Brakes, Z Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain make this the Z of CJ’s dreams.

 

CJ’s Z Story

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

CJ: “When I was in my teens I was a huge WRC fan, and rally led to my passion for Japanese cars. Video games like Sega GT and Gran Turismo also helped. I think my first exposure to classic Z cars was when I was about 17 and it was probably in a bootleg Wangan Midnight VHS that my buddies and I found at a Japanese video rental place. I’ve loved the aesthetic of the S30 since that time. It’s not an exaggeration to say I’ve dreamed of an S30 with factory fender flares, an air dam, and a 432 style wing for over half my life, but I never had an opportunity to own one.”

 

In 2017 CJ acquired his best friend Travis’ 1971 project car that hadn’t run since the 1990s. Over the next four years, and with significant help from his wife, the duo restored or refurbished just about every part of the car.

   

CJ: “We fully refurbished the dash, redid the entire interior, and mechanically refreshed the brakes and drivetrain. The exterior received new factory matching paint, new gaskets, tail lights and corner lights I refurbished, RS Watanabe wheels, and flares from Marugen Shoukai. The car also got BC coilovers, Techno Toy Tuning arms and subframe components. The L24 was replaced with an L28 and triple Mikunis, assembled in my garage. There are so many good memories wrapped up in the restoration of this car and it was a blast to learn new skills throughout the process.”

 

In October 2020, with the engine he built with his Dad the car drove under its own power. CJ was proud, and the moment was satisfying and exhilarating, right up until it wasn’t. He had been building drift cars since the early 2000s but the first drive of this car made it clear that if he wanted a car that was sturdy, reliable, and confident to take on road trips, he’d need to get some help from a specialist…

 

CJ: “And that’s where Z Car Garage came in. I’d been an avid reader of the Z Car Blog throughout the restoration and had even spoken to Rob occasionally about various issues. There was never any question as to where I wanted to send the car for finishing school. So in Spring of 2021 I shipped the car from my small Colorado mountain town to San Jose. The initial plan was to have Rob and the crew bring it that extra 10% to completion. Thankfully Rob understood my vision and suggested additional work to ensure I actually wound up with the car I’d been dreaming of for so long.”

After discussions with CJ we took on his project and he signed on to get our Z Car Garage Big-Brakes, Z Car Garage CV Axles and bring his Z to the finish line.

 

Drivetrain

 

After sorting the engine and installing brakes/suspension we were stoked to get CJ’s car running. Before hitting the dyno we always do a test drive on the street and we noticed low oil pressure on the dash gauge, despite lack of obvious noises or behavior. Low oil pressure unfortunately was confirmed with our own gauge, and so we were at a crossroads with this 2.8 engine that CJ assembled together with his Dad. A decision was made to send it to Rebello Racing for a 3.0L build and it really came alive. CJ already provided the ph44 Mikuni carbs and we installed what every triple-carbed L-series needs: a ZCG Heat Shield!

  

A Moroso competition baffled oil pan prevents oil starvation with high cornering loads:

 

Cj was having header fitment issues. We ensured clearance was no longer an issue with a Fujitsubo exhaust system from manifold to muffler. These newer units have better fitment, but every car is different. More photos of the exhaust system in the gallery below:

        The engine bay turned out great with general clean-up and sorting:

 

Driveline Upgrades

With the 3L engine in we focused on the transmission and rear axle. To handle the power from the 3L engine we replaced the stock 4-speed 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. When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel:

 Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin):

   

As CJ mentioned, he is avid reader of our zcarblog and no stranger to the “Butters” phenomenon: clients desire a similar setup for their own S30s. Our 1971 shop demo Z Mrs. Butters proudly features our Z Car Garage Big-Brakes, Z Car Garage CV Axles, ZCG Heat Shield, 6-speed transmission, full KW suspension (releasing soon) and 3.2L engine with triple-Mikuni induction. 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 replaced the existing CV Axles (left) with ZCG units (Right). CJ received set #00395. Also visible are the T3 control arms:

 

Dyno Tuning

 

Rob dyno tuned the Rebello 3L engine with jetting, A/F and performance in mind as CJ would be driving this Z at 6,500ft above elevation. It put down a stout 261hp/220tq to the wheels:

 

Enjoy the L-series music in this extended video of CJ’s Z including dyno runs, test drive with Rob and engine/exhaust sounds…volume up!

 

ZCG Big-Brakes

We are proud to have several of our ZCG products on CJ’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.

  

We removed the stock brakes and installed our ZCG Big-Brake kit. Not only do they perform, they look great behind the 15×8 Watanabe wheels!

     At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. New OEM Nissan master cylinder and Factory handbrake functionality IS retained!

Details

 

Cj’s project involved more than installation of our ZCG performance upgrades and dyno tuning. We nut and bolted the entire car, installed T3 RCAs to fix suspension geometry up front, set the ride height, scaled and aligned it. The gas tank was removed and all fuel recovery hoses replaced along with a new fuel pump. The clutch pedal was removed to allow welding-up of the pivot hole that had wallowed-out. This ensures proper clutch travel to work with his new KA24 transmission/clutch combo. The master cylinder, slave and hose were replaced with all new Nissan OEM components.

 

Driving is Believing

  

CJ’s Z was shipped back to Colorado in November and we are happy to report he is Enjoying the Ride in his dream Z…

CJ:  “Like so many project cars, the goals of the build evolved and the car grew into something significantly more impressive than the onset of the build. Throughout the car’s time at ZCG Rob was great to work with and he always understood my vision and explained how to make it real. By the time the car came back to me in November of 2022 it may have still looked like the car I sent away, but the similarities were skin deep. From the brakes to the drivetrain the guts of the car were totally new and upgraded.”

   

CJ was impressed with the upgrades from Z Car Garage:

CJ:“The car is incredible now. It is an absolute animal when you give it full beans and the sounds and sensations it creates for me as a driver are like nothing I’ve ever experienced in a car. It is well mannered and drivable at low speeds and can cruise comfortably and quietly in 5^th on the highway, but the instant you open up the right pedal it will shove you back in your seat with a massive grin on your face. The best thing about the car to me is the way each piece is set up to work together. The new ZCG brakes and axles work with the new transmission, OS Giken diff, suspension set up, and stout Rebello 3L to deliver a driving experience that is both exciting and confidence inspiring.”

 

CJ: “One of the coolest things about these old Z cars is the variety of people who love them. When I am out for drives I am just as likely to encounter a 19 year old kid who loves the car as I am to encounter a 79 year old with the same enthusiasm.”

We enjoyed working with you CJ, thank you for your support! Enjoy the photo gallery below.

Rob: “We enjoyed working with CJ, not only does he have a bitchin’ Z car, he’s fun to work with, very responsive and we had great conversations. He did not hold back in communicating his needs and we were happy to deliver the goods like we always try to. Honored to have folks locally and globally that want to work with ZCG. Thank you so much CJ, Long Live The Z.”

Dear Zcarblog readers, it’s been a busy year and we are catching up on blog posts. Please enjoy our belated race reports from October and November.

WE LOVE RACING! Z Car Garage attended two events with Classic Sports Racing Group (CSRG): the Charity Challenge at Sonoma Raceway 10/2 and the CSRG Finale at Thunderhill Raceway 11/4. We raced and supported several client’s Datsun 510s running in the B-Sedan Group (John Morton Cup). Everyone had a blast, enjoy our race report with in-car video and photos below.

  

CSRG Charity Challenge

Z Car Garage Supports Six Datsun 510s!

 

The 19th Annual CSRG Charity Challenge was held on October 1-2 and we had one of our largest ZCG client groups with 6 B-Sedan 510 race cars. It is our pleasure to bring more enthusiasts into the world of vintage racing. Z Car Garage trackside services include full race support and car-preparation to make client’s race days seamless and worry-free so they can focus on driving. Before a race weekend we confirm that your car is running well and make necessary adjustments while on the chassis dyno:

 

#88 Todd Rueppel

Todd had his first Z Car Garage trackside support experience with us at the Laps For Laguna event!

 

#7 Kelvin Tse

Kelvin and his brother Kenny are regular ZCG trackside support clients…

  

#71 Ed M

Ed M is also a regular ZCG trackside support client, we also prepare his Porsche 911 for vintage events!

  

Gabe’s B-Sedan. Full report on our race preparation of this 510 soon!

Enjoy this video of the B-Sedan Datsuns in action at the Charity Challenge with photos and race recap from Rob below:

 

Rob recaps the Charity Challenge B-Sedan races:

“Everyone had a great time at the Charity Challenge. Gabe unfortunately had an engine failure, but before that he was putting down some good times. The Tse brothers Kelvin and Kenny did really well and Ed was rocking and rolling. In the B-Sedan class I had really good racing with Parker McKean in his Alfa Romeo. The group wasn’t as large as it usually is, but still fun!”

 

“Another mechanical was in the afternoon race where Parker got a really good start but I noticed my 510 was down on power. Coming out of Turn 10 I noticed my temperature gauge was higher than I’d ever seen it. Pulled in and unfortunately I had a failed head gasket. So, double mechanicals (IMSA Z, below) for me. Very rare but still had a great time racing with the group.”

The 2023 Nissan Z as Pace Car!

 

Z Car Garage has been fortunate to spend some time with the 2023 Nissan Z prior to its public reveal. We asked Nissan if they would lend us the New Z for a good cause at the Charity Challenge and they happily obliged with a Performance model in Two-Tone Ikazuchi Yellow TriCoat / Super Black:

Rob was happy to wheel the New Z around the track:

“One of the coolest things about this years’s Charity Challenge was that Nissan lent us the new Z for a pace car and charity rides. We loved seeing Nissan’s new sports car before its release leading the field of vintage cars in every run group. Even the pace car driver was super stoked. In its 19th year the Charity Challenge has raised millions for children’s charities and they allowed me to be a driver on Sat/Sun to give 4-5 rides which included a warm-up lap, race lap and cool-down lap.”

“I really enjoyed driving the new Nissan Z at speed, granted it certainly wasn’t at 10/10ths but I was to able entertain riders that donated for charity. It did really well and it is powerful, and I gotta tell you all weekend long there was crowd around that new Z car. I really appreciate Nissan believing in us..bringing both the new and old sports cars together and thank them for their support. Can’t wait to have our own 2023 Z at Z Car Garage.”

 

Enjoy this video with in-car action from the New Z with Rob Fuller giving charity rides around Sonoma Raceway:

 

The #49 Joel Anderson IMSA GTU 240Z

 

Rob also raced the #49 Joel Anderson IMSA GTU Datsun 240Z for the first time at Sonoma Raceway:

“My IMSA car has pretty good history at Sears Point (now Sonoma Raceway); it came from the Bondurant School and actually held a record there. This was my first time behind the wheel of the Z at this track and unfortunately we had transmission issues. On Sunday’s race I was 3rd in Group 8 against an IMSA Z and 911. Both drivers were fast. We had made some changes to our Z between Sat/Sunday so I was excited for the big feature race. On lap 3 I had sheared the roll pin in 3rd gear so it would no longer go in to 3rd. Exited at the carousel, to avoid contact with other racers. We look forward to developing the IMSA car further.”

 

The Charity Challenge was fun with the usual group of folks, Tank, Meghan, lots of snacks and good times. We are excited for next year’s event!

 

The CSRG Finale

On November 4-6, Classic Sport Racing Group (CSRG) hosted the finale of The John Morton Cup. The 3-race series, named after legendary Datsun racer John Morton features the Historic B&C Sedan class battling at Thunderhill Raceway.

 

Every year CSRG ends with the finale event at Thunderhill and it’s frequently missed due weather/rain conditions. We always try to make it out for the club. It’s a fun-filled weekend that is super laid-back with a great dinner party at the end.

The Return of #72 Tom Dockery

 

We have helped Tom build and prepare his Ex-Norm Balzer/Koobation 510 for several years. Unfortunately the car was wrecked at Sonoma Raceway back in March from oil on the track. Z Car Garage rebuilt the 510, making a triumphant return to last year’s Velocity Invitational event with Rob Fuller as driver. For the CSRG Finale however, it would be Tom’s first time back at the helm of his very own B-Sedan 510:

   

“I came into the race weekend with a lot of apprehension. Rob had shown the Vintage world what the car can do in the right hands and now it was my turn to put up or shut up, at least that was part of what was playing in my head. Also playing the background was my fear of damaging the car. So many people had given so much time, priority and resources, I had a lot of angst around preserving its current condition.”

 

“But what really played out once behind the wheel was the loss of Race mentally/conditioning. Physically I was all there and even though there was some proper racing line adjustment needed, the biggest issue was getting comfortable with the car’s REAL limits. It was a head game for sure. I spent Friday and Saturday working with Rob to better understand this and by Sunday, I could start to see a difference. On Sunday I was able to trim 4-5 seconds off my lap times from the previous days. I am still a little off and like getting fit again on my bike, I have to continue to get fit behind the wheel. It took me almost 3 three years to get to the front half of the racing pack, now I have to accelerate that level of conditioning in 2023.”

  

“As always, the ZCG team support at the event went well beyond just the car. Had a blast throughout the 3-day event.”

Thanks Tom, we were proud to see you back on the track! Enjoy this video with in-car action from Tom’s Ex-Balzer/Koobation Datsun 510:

Gabe’s Datsun 510

Gabe R. has been an avid track day weekend warrior for five years and we will highlight our preparation of his B-Sedan 510 soon. Let’s hear his race report from the CSRG Finale:

“I was beyond excited to get some legitimate wheel to wheel action after acquiring a Datsun 510 last September. Unfortunately, mine is a chapter in the long and storied history of the “race ready” race car. In my first event at last year’s Charity Challenge I found the car to be extremely driver friendly, and was even able to put down a few pretty quick laps. That pretty much sums up the good parts. On the not so good side, in my second session of the weekend, the gearshift lever broke off in my hand going into turn seven. In my third session, a spark plug wire popped off the distributor and ended my session prematurely. And immediately before my last session of the weekend my starter motor died, causing me to miss it entirely.”

 

“Fortunately for me, the vintage racing community is a wonderful group of friendly, helpful people. Over the course of the weekend, I was lent a hand by the likes of Larry Oka, Jim Froula, and the Z-Car Garage crew. My second weekend out was at this year’s David Love Memorial, and my fortunes did not improve. Not realizing how quickly Hoosiers wear out, combined with my car’s unfortunately welded diff, I spent the majority of my time on track over the weekend just trying to prevent the car from snap oversteering into a wall. Even worse, I blew a head gasket in the first session on Saturday, At that point, I sent the car down to Z Car Garage to have Rob’s team transform it into a proper competitive car. Engine rebuild, limited-slip differential, suspension overhaul, new clutch, new transmission, as well as a slew of other upgrades and improvements have transformed the car into a beast.”

 

“Finally equipped with a seaworthy vessel, I spent the last two CSRG events — the Charity Challenge, and the season Finale, being supported by the Z Car Garage guys, culminating in a fantastic weekend at the season finale. With the support of Rob and his crew I ran the 4th fastest time of the weekend – behind only Troy Ermish, Rob Fuller, and Jim Froula, and finished 3rd in the Sunday feature race despite starting in 7th due to a spin in the Saturday feature race. Most of all, I had an absolute blast hanging with Rob and his entourage. Rob’s infectious positive attitude makes it impossible to have anything but a good time.”

Enjoy this video of Gabe putting in work at Thunderhill and achieving a personal record!

 

“From their impeccable car preparation standards, to their attention to every detail, to helping their drivers get prepared to head out on track, as well as Rob‘s exceptionally helpful driving tips Z-Car Garage consistently exceeds my expectations in every way. I absolutely cannot wait to get back out on track with Z-Car Garage in 2023!”

Privateer Spirit

 

Special shoutout to our friend and Datsun Historian Glenn Chiou raced his Ex-Finn/Harris U2.5L Trans-Am ’68 510. It’s worth noting that not unlike privateers of the period, Glenn builds his race cars, maintains and manages racing efforts himself. Not an easy task so we applaud his work ethic. Glenn builds some beautiful Datsuns and we will highlight this 510 soon as it features our  Z Car Garage CV Axles and dyno tuning.

 

Rob in the BADD 510

For the CSRG finale the ZCG crew included Rob, Tom Dockery and Gabe R:

“Both Gabe and I had mechanical failures in last event’s Chartiy Challenge. My engine lasted two seasons at full-tilt boogie and it had a compromised head gasket so my friends at Rebello Racing were able to refresh it in between events so the BADD car was ready to rock. Gabe’s engine had a pretty horrific failure and Rebello was also able ot get him back on the track too. Special thanks to the team at Rebello Racing including Dave, Mark and Brian for giving us the best hp/tq that we could ask for and keeping us on the track. I was driving the Miata in vintage Spec- Miata group and BADD car in Group 9 John Morton group B-sedan.”

 

“Tom and Gabe were doing great. Gabe is really picking up the pace. We did some downloads and he is getting fast, finishing on podium in the feature race. Tom was just getting reacquainted with the car and he was really stoked to be able to do well at the end of the season. Unfortunately Josh and Troy Ermish were not in the run group so there were not many people to run with. I started in the back it was a challenge and also fun to go through traffic. Another highlight was being in group 8 with my Miata amongst the big-boy v8 cars it was an awesome vintage race in the rain.” 

Enjoy this in-car video of Rob in the BADD 510 at Thunderhill:

A different perspective: Steve Walker also posted this cool in-car video of Rob and the from his BMW 2002:

 

CSRG hosted a Saturday night night banquet and it did not disappoint. They had folks dress up in costumes since it was close to halloween. Ross Lindell dressed up as Rob Fuller and it was quite funny. Side note: Rob actually did SCCA drivers school in the Randy Pobst Miata that Ross brought to race. The evening included  awards, and great conversations recalling the highs and lows of another year of vintage racing gone by. Can’t wait for next year!
