We love to see our parts installed and used on client’s cars. Race car driver and Datsun Historian Glenn Chiou is running our Z Car Garage CV Axles in this 1968 Datsun 510 U2.5L Trans-Am race car!

Glenn was preparing to debut his freshly restored 510 for the 2022 Velocity Invitational event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed the set himself with ease:

 

We also provided dyno tuning services to prepare him for the race weekend. The fresh Rebello L18 with Solex/Mikuni 44phh induction and BRE intake made great power.

 

Listen to this 510 make sweet L-Series music on our dyno in the video below. There is also race/paddock action with Glenn behind the wheel:

 

Privateer Spirit

We are happy to report that Glenn successfully raced at the Velocity Invitational event. It’s worth noting like privateers of the period, Glenn builds his race cars, maintains and manages racing efforts himself. Not an easy task so we applaud his passion and work ethic. Glenn builds some beautiful Datsuns and this historically-significant 510 is a shining example.

Glenn championed a vintage race group dedicated to the Historic B&C Sedan class and organized a “Celebration of the Two Five Challenge” display at the 2022 Velocity Invitational event. Two of the most iconic cars were present: the ex-Morton #46 BRE Datsun 510 (with Pete Brock below) and ex Kwech #3 Wetson’s Alfa. Yes that is Glenn with the legendary John Morton! Let’s take a look at the history behind Glenn’s Trans-Am 510 before we get into the restoration:

 

The Ex-Finn/Harris U2.5L Datsun 510

 

Glenn has a passion for re-telling the stories of legendary privateer Datsun racers and his penultimate restoration project was this 1968 Ex-Finn/Harris U2.5L Datsun 510, serial number PL510-023047. It is one of very few surviving cars that competed in the SCCA Trans-Am Two-Five Challenge, or more commonly known as the Under 2.5 Liter Series.

 
In 1972, Bob Finn acquired the car from a used car dealership in Santa Barbara, California. The car was sponsored by Bob Nolan Datsun and Chuck’s Shell Service in Santa Maria, California. Competition Street and Rally (CSR) Racing, a shop Finn ran out of Chuck’s Shell Service, prepared the car for competition. It is one of two cars in which an entire package of go-fast parts were purchased from Brock Racing Enterprises in El Segundo, California, as part of their “BRE kit car” program. Mac Tilton, then BRE Crew chief and engineer – later Tilton Engineering, developed the suspension and provided all machine work. Bob Finn and Ron Harris began racing #37 in late 1972.

 

Its first two races were the two final races of the 1972 SCCA Trans-Am Two-Five Challenge season at Laguna Seca and Riverside International Raceway, finishing 15th and 23rd. Unfortunately 1972 would see the end of the Trans Am Two-Five Challenge, but that would not stop Finn and Harris from continuing to race the car. They competed throughout the 1970’s in the SCCA B-Sedan class both regionally and nationally with numerous first place finishes, often beating out factory race teams. While Riverside International Raceway was its home race track, the car could also be seen racing at Willow Springs International Raceway, Laguna Seca Raceway, Sears Point, Portland International Paceway, Ontario Motor Speedway.

  

In that time, Finn and Harris competed against the likes of John Morton, Horst Kwech Harry Theodoracopoulos, Bobby Allison, Walt Mass, Dave Madison, Corky Bell, Norm Balzer, Pat Daily, and many other prominent racers. Bill and Jack Johnston acquired the car in 1979 and would go on to race the car for the next 33 years. Bill Johnston and Steve Dragus shared driving duties, while Jack was the crew chief. Dragus, who was best known for the building engines for Don “The Snake” Prudhomme, prepared the engines. Johnston and Dragus won three regional Cal Club Championships in the 1980’s, and would go on to win the last SCCA GT4 national race at Riverside Raceway before the track closed in 1989.

Restoration

 

The Ex-Finn/Harris Datsun 510 was not always in the orange livery shown above. When Glenn acquired the car several years ago it was red and he ran with this livery at many vintage racing events…until it was time to restore it back to its former glory…

 

Glenn is no stranger to vintage race car restoration. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this car himself and it is now back to the Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn also restored the Different Drummer Racing Z raced by Greg Sorrentino. This IMSA GTU Datsun 260Z features our Z Car Garage CV Axles and dyno tuning:

 

The 510 was dissembled for paint and bodywork, using period photos to guide the livery hand-applied by the talented Real Ralph:

 

As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces or use period-correct/surviving parts with archival guidance…shown below: vintage SW oil cooler, BRE remote oil adapter, expansion tank and BRE intake manifold:

 

Glenn assembled the interior with Mil-spec switches & motorsports grade wiring:

 

The fresh Rebello L18 is about to be installed…all done by Glenn himself in his home garage:

 

I was lucky to visit Glenn to see the restoration in-progress and it was simply a feast for the eyes…plated chassis parts, cool bits of history everywhere…plus the BADD 240Z nearby 🙂

 

Datsuns Are Driven!

With the restoration complete, Glenn has been enjoying the Ex-Finn/Harris U2.5L 510 at vintage racing events throughout the year. Follow his racing adventures on Instagram with more photos in the gallery below:

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!

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:

Photo by Josel Cobangbang

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!

We love motorsport and it is our pleasure to bring more enthusiasts into the world of vintage racing. Z Car Garage offers full trackside support and race car-preparation so you can focus on driving. Our client Todd R is a great example of ZCG trackside support in action. He’s been racing his Datsun 510 privateer-style for the last few years and hired us for the first time at the Laps For Laguna event back in May.

Z Car Garage had a blast racing and supporting Datsun 510 race cars running in B-Sedan Group 9 (John Morton Cup). We were super proud of Todd: he was able to concentrate on his driving, achieving his highest placing (p6) and personal best lap (1:48.3) time. You can see our full report from this HERE, and let’s take closer look at Todd’s experience with Z Car Garage trackside services.

 

Race Prep for Todd

 

Todd had us prepare his B-Sedan 510 prior to the Laps for Laguna event with standard track-event services including dyno tuning and alignment. He also purchased a set of 13×7 Panasport Wheels from ZCG. We are proud to offer 13×7 Panasport racing wheels in perfect fitment for your B-Sedan/TransAm series Datsun 510 running vintage-class spec 205/60/13 Hoosier R7 (and other) tires:

 

The welded diff was replaced with OS Giken limited-slip (4.38) unit. Diff services are performed in-house at ZCG:

   

We changed the ignition, spark plugs and dyno tuned the L-Series engine for 110 race fuel.

 

Enjoy this video the dyno tuning sessions at Z Car Garage and in-car race footage from Todd, volume up!

 

510 Beginnings

Let’s take a look at how Todd got into 510s…

“My history with the 510 begins in my childhood. We had a 4 Door 510 as a family vehicle and went everywhere in it. I have many memories of tinkering on cars with my dad in the garage. My first car at 15 yo was a Datsun 1200 I bought with my twin brother for $200. Engine was dismantled and all parts in a box under the hood sitting on the engine block. We put it back together w/Dad at night after he got home from work using the Haynes manual. My first car I bought myself in 1988 out of the classifieds was a 1972 Datsun 510, Lowered, L18 and a webber carb, 5 speed painted white. Great car, went everywhere especially to the Santa Cruz Beach. I lived in Livermore at the time. Sadly it got smashed into in front of my parents house and that was the death of it.”

 

“I received my racing license in 2015 in a rented 510 from Larry Oka (The One and Only)( nicknamed the THRASHER) I subsequently bought that car to continue racing for 2015 and 2016 in SCCA ITC SFR region racing at Laguna, Sonoma and Thunderhill. I became the 2015 San Francisco Region Champion in ITC for SCCA that year. At the end on 2016 I was handed an opportunity to purchase a Vintage racing ready 1971 Datsun 510 again thanks to Larry Oka. I made the deal and started racing with CSRG in Vintage sedan racing. This was where my heart was. I had been attending Monterey historics for 30 years and finally was going to be a Vintage racer. I raced and learned with that car but it needed to be better prepped for vintage, its livery was a bit contemporary and the car was Street/ITC built.”

 

“I had the car painted to its current day Black over White #88. I wanted to make it my own. I modeled it after the F.A.R Performance Datsun 1200 Livery of the early 70s to pay homage to the bay area Datsun performance shop in the 70s and 80s. The ZCG of its day. They had a successful racing history with Roadsters, 1200s, 510s and Z cars. I then brought the car to Troy Ermish who performed all the proper B Sedan Upgrades at his shop over the course of a few months. As more 510s started showing up in Vintage racing…Like Troy, I was left in the back. I knuckled down and raced as hard as I could. I reminded my self of a saying by the great Paul Newman..”Its more fun to make a slow car go fast than a fast car go slow”. The prize at the end of the day in Vintage racing is returning home ALL in one piece. I sourced a Rebello L1800 and installed it, and was able to race two races in 2021 after install  at Sonoma and Thunderhill.”

 

“As for Rob…We met at racing school in 2016 when he attended and I was working for Larry Oka racing for the weekend. He had that contagious energy of course and that’s where I learned of Z Car garage. As a Datsun owner racer I knew I I would need his services in the future, and of course we ended up racing together on a regular basis with CSRG. We would always be staged together in the Paddocks since all the 510s typically parked together.”

 

“I have always been a Do it yourself’er and was able to take care of all my needs up to this point, but at that Sonoma race in 2021 I had issues. I sorted out some problems but had a persistent misfire. Thankfully Magic Hands Joshua Corwin of ZCG was providing Track Support to Rob and others that day and my problems caught his interest because he’s a fixer.  Rob had allowed him to step away for a moment and he was able to determine my ignition plate in the distributor was loose and causing a misfire. They also supplied me with a Coil and plugs as part of the fix. Without Z Car my weekend would have been over if not for them. THIS WAS MY AH HA moment. With Rob’s thorough knowledge Datsuns and racing and the skills of his guys, Thats a win.”

 

Success at Laguna Seca with ZCG Race Support

 

Todd’s experience with us at the Laps for Laguna race event was so good we had to share it with our readers and anyone looking to join the fun…

“My first race this year was in May at Laguna Seca. I hadn’t had my car out of storage all winter and because of a crazy busy work schedule I couldn’t do my own prep and services prior to racing. I got my car into Z Car Garage and they more than dialed it in in just a few days. Nut and Bolt check, Dyno tune, alignment, scales. My car had never been better. I also enjoyed track side support that day at Laguna. I had to worry about NOTHING when parked under that ZCG EZ up. It was a difficult adjustment and I didn’t know what to do with myself. Rob told me to worry only about me, the car is covered. That security knowing Z Car was on the job simply made me faster, finally everything was dialed.”

 

“First session I finished 14th, second timed session I finished 10th and For the First Time ever, Sunday afternoon race I finished 6th overall in group 9 B Sedan group. This was possible because ZCG had me covered, the car ran and preformed better than it ever had. I was more relaxed going onto each race, AND iIdiscussed every session with Rob to preform better for the next race to come. Simply the best. I would recommend Z Car Garage Track Support to everyone.”

 

Thanks for trusting us with your race preparation Todd. We are very proud of you and happy to have you part of our group!

Last week the Brock Racing Enterprises (BRE) Datsun 510 #46 race car arrived at Z Car Garage. Despite being against all odds, our hero John Morton drove this 510 to SCCA Trans-Am series championship victories in 1971 and 1972, putting Nissan on the map and fueling every Datsun enthusiast’s passion. In preparation for this weekend’s Velocity Invitational at Laguna Seca we dyno tested this legendary race car. Turn those speakers up and enjoy the video!

 

Huge thanks to Nissan and Randy Jaffe for giving us the opportunity to prepare the car. It was surreal to have it in our shop:

 

We spent hours admiring and pouring over all the details on this historical 510. Note the swirl chamber, BRE exhaust header, oiling system and hydraulics:

 

The chassis reveals hard-earned battle scars:

 

Note original Koni shocks, Porsche 911S calipers and oval section of exhaust, more photos in the gallery below:

 

Living Legends at the Velocity Invitational

 

Z Car Garage is really proud to announce special guests (and our heroes) John Morton and Pete Brock will be at the Velocity Invitational on Friday and Saturday. This is a rare opportunity to get an autograph and chat with these iconic gentlemen.

  

To celebrate the 50th Anniversary of the Trans Am (under 2.5) racing series, Z Car Garage coordinated with Nissan Corporate to have the original BRE Datsun 510 displayed with the Horst Kwech Alfa Romeo at the Velocity Invitational. See the actual race cars in person, only at the Velocity event!

  

See you this weekend at Laguna Seca!

Race car driver, restorer and Datsun Historian Glenn Chiou has been a friend and client of Z Car Garage for many years. His canyon-carving companion is this 1972 Nissan Fairlady 240Z-L featuring our Z Car Garage Big-Brakes and dyno tuning. Before we get into the details behind this rare, right-hand drive survivor let’s take a look at Glenn’s Datsun story.

 

Racing Is Life

 

Glenn is passionate about vintage racing and loves re-telling the stories of legendary privateer Z car racers. Like privateers of the period, Glenn builds his Z cars, maintains and manages his racing efforts himself. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence or his Ex-Greg Sorrentino IMSA 260Z at events like the Velocity Invitational and Rolex Monterey Motorsports Reunion. Glenn restored these cars himself and the VIPS Z is now going back to Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas.

 

Glenn also races a Datsun 510, championing a vintage race group dedicated to the Historic B&C Sedan class. He is currently restoring the 1968 Ex-Finn/Harris U2.5L Trans-Am 510. You can follow his racing adventures on Instagram.

  

Finding a Fairlady

 

When he’s not working on race cars, Glenn is enjoying his 1972 Nissan 240Z-L. It’s “the dream list” car that started his Datsun passion. Glenn has owned it for several years, enjoying it as a back-road burner on the street and rallye events.

 

The Z has a great story behind its acquisition. Purchased from Chiyoda Nissan as a used car by US Air Force lieutenant David Zabel in ’73, it was brought back with him to the States in 1974 and driven until 1992. Glenn found the Z in 2010 sitting in a Datsun collection in Ben Lomond, Ca. Below are period photos from Japan in the 70’s at Yokota air base near Tokyo and ski-trips at Lake Tahoe:

 

Find out more about the story behind this right-hand-drive survivor over on Petrolicious with photography by Courtney Cutchen with a great video. To this day it still wears its original paint, interior and neat Japanese-market features like the 8-track Nissan/Hitachi radio and passenger side foot rest. Glenn also sourced the rare rallye clock that is functional, running off an oscillator box in the passenger footwell.

 

Drivetrain

 

We actually tuned Glenn’s Fairlady back in 2012. The 3.0L stroker is fed by triple-Mikuni induction backed by a Nissan 240SX 5-speed transmission and OS Giken limited-slip diff. With Rob’s tuning it produced one of the highest dyno numbers we had seen back then putting down 249hp/227tq to the wheels:

 

Z Car Garage Big Brakes for Glenn’s S30

 

The Z clearly had more than enough power, but braking was always something Glenn wanted to improve and once he heard about our  Z Car Garage Big-Brakes  for small wheels he became a believer after test driving them. Rather than tell you how we feel about this product, let’s hear Glenn’s experience.

“Throughout my years of Z car ownership, I have run a variety of brake setups. My Z cars have seen everything from restored OEM Sumitomos, Toyota 4×4’s, trick Wilwood setups, even frankenstein’d Baer calipers. There is no doubt that it has been one area that I have never been completely satisfied with. Over time, after many years and attempts to find the ‘perfect’ setup, I had given up and just settled for what I had.

The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me. On my vintage 240z race car, we use multiple master cylinders, swap them in and out, fiddle with our brake proportioning valves, fine tuning them to fit our driving style and preference. We are trying to find that ‘racer’s edge.’ In all honesty, when it comes to a street car, I want nothing to do with all that.”

“Wheel sizing and style was also extremely important to me. I love old school wheels and the sizes they came in. I needed a brake caliper that would fit under my 15” Watanabe RS wheels without having to shave or drastically modify my setup. If it was not for being in love with these wheels, I would have opted for Z Car Garage’s larger big brake kit.”

Our clients asked us to make a BBK for smaller wheels so even a guy running 14″ vintage 5-slots slots could brake like a modern sports car. Typical big-brake kits use a 4-piston setup up front and a ZX in back; Proportioning is hard to get right, varying from car to car. We wanted a brake system that suited the car and totally bolted in, no M/C change, no proportioning valve, no booster change.

 

Working with Stoptech again, we developed this smaller BBK as a direct bolt-in solution for the 1970 to 1978 S30 Z cars. We’ve been with Stoptech since the beginning and love their products. With over 150 brake kits sold, we are stoked with all of the positive feedback.  Let’s get back to Glenn and hear his initial impressions of the big-brake kit:

“Rob informed me he was working up a solution and he wanted me to be test the brake kit. Rob promised three things – they would brake amazing, they would fit under my 15” Watanabes, and they would feel as if they belonged on the car. Did I doubt it at first? Sure, a little. However, I also knew that the fit and finish of all products that came out of ZCG were top notch, and that Rob thoroughly tested all his products against his own standards. Which I’m sure everyone knows, are extremely high.

In preparation for the Monterey Historics last year, I had brought the Z race car to the shop for dyno time. Rob gave me the keys to his Butters Z and said “Go drive it.” Under 14″ wheels sat his brand new ZCG brake kit. I gladly accepted and took the car for a ride.”

 

“WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car, and these were on a car with stock suspension, tires and probably cruddy tires! I told Rob, “sign me up!”

Glenn wanted to run the brake kit on his Fairlady and we happily obliged. He had also been gearing up for a road rallye so the braking system would be throughly used. You can see his Z (top left) along with his buddy Erich C’s S30 (top right, also getting a ZCG BBK!):

 

“Then came the day Rob called me up and said they were ready to rock and roll. Lucky for me, I was just about to head out on the 1000-mile Coastal Range Rally! The kit came with beautifully anodized front and rear calipers, hats, rotors, brakes lines, reversible brackets (for early and later Z offsets), and a factory ⅞” master cylinder. Read that again… Yes, a proportioning valve was left out from that list! The brakes were a straight bolt on and ZCG did all the math to get both the master cylinder size and piston sizes correct. We brought the car in for install and within a day the car was ready to rock.”

 

 

Glenn’s 240z now had 4-wheel disc brakes ready to tackle the street and rallye:

  

And of course, the brakes fit beautifully under the 15″ Watts. Kane approved, and Glenn was stoked:

 

“I could hardly wait to jump in the seat of the car and take it for a spin. The brakes were now on a car with suspension, tire, power, and a proper alignment. It was everything I had remembered from driving the Butters Z and MORE. The brakes performed flawlessly on the Coastal Range Rally, taking abuse from California’s most challenging roads”

 

“Attention to detail goes a long way. This is exactly what these brakes delivered, and what continues to be delivered by ZCG.

LONG LIVE THE Z!”

Still Enjoying the Ride

 

Last weekend we caught up with Glenn and took the FairladyZ out for a spin to stretch its legs. Glenn was one of the first clients to run our Z Car Garage Big-Brakes back in 2018 and we are happy to report that he is still braking late and deep all while Enjoy The Ride!

 

Over the years we’ve been fortunate to drive our Datsuns together through the local Bay Area backroads. Glenn’s Z always looks sharp while sounding sensational. Here is a video from our recent drive, volume up and enjoy!

 

You can find him carving through the Santa Cruz Mountains or taking a break at Alice’s Restaurant off Skyline…

 

While we were catching up with Glenn he reminded me that the ZCG Big-Brakes are better than any of the other setups he’s driven, the only one that feels and behaves like a modern car. He loves them.

 

What’s next for the Z? Glenn says its due for a refresh..NOS door panels, some engine bay fuel plumbing updates and maybe a change from the Ground Control/Tokico coil-overs. Aside from the Z Car Garage Big-Brakes , it remains very much the same as he set it up over 10 years ago. Big thanks to Glenn for the support and feedback. We look forward to many more race events and drives with you. Enjoy the photo gallery below and LONG LIVE THE Z!
