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!

At Z Car Garage, the Datsun 510 is very close to our heart. Our hero John Morton piloted a 510 in the Trans Am racing series to put Nissan on the map, fueling every Datsun enthusiast’s passion for hot-rodding the humble economy car. We also have our share of race, personal and project 510s. When Mark G contacted us to work on his 510, we happily obliged especially after learning that it was built by our friend, fellow racer and Datsun 510 guru Troy Ermish.

 

510 Beginnings

 

Mark is an avid car enthusiast, growing up here in the South Bay. His first car was a lowered Capri that he tracked in the 80’s at Laguna Seca. He attributes his 510 passion from its rich racing heritage:

 “I was introduced to Sports Car racing at Laguna Seca in the mid 70’s. I have been going to most all of the different events ever since. My favorite was Sports Cars racing, Camel GT’s, IMSA, ALMS. Thus the ‘Poor Man’s BMW 2002’, my recent 510 is my third and hopefully last. Number 2 was also brought back from the dead and used to commute and cruise over Highway 17 to Aptos to work for my Father’s business. The surf rack was installed to haul all kinds of stuff.”

 

In 2015, Mark decided to fulfill his dream of another 510 and bought a project car:

“I wanted something I could turn into a street racer and autocross car for my son. As in any extensive full blown renovation, everything on the car has been touched. I tore it completely apart, soda-blasted the car, personally sandblasted every bolt and part on the car, welded in new floor panels and rebuilt the trunk, back panel and rear valance.”

The project car:

 

Mark’s extensive bodywork:

 

“I met Troy Ermish early on in the process, so when the floors and trunk were repaired, the car was trailered to Troy for a full roll cage, front fender wells were cut back and jack points installed in the rocker panels at the “B” Pillars.”

 

After 18months of bodywork, which Mark was heavily involved with, it was back to Ermish for the final build out. The car was purchased with a 1600 and funky 4 speed, but Mark also scored a 2000cc with two side draft Mikuni’s and a ZX 5 speed transmission. The engine was sent to Rebello for a full rebuild and upgrade to 2360cc spec.

 

T- Square Brain

 

Mark studied art in school and his attention to detail throughout the 510 impressive. From the no-frills interior to uncluttered engine bay it’s no surprise that he earned the nickname “T-square brain”. Each time I see this car it reveals another level of fanaticism that reminds me how awesome Datsun-owners are. Enjoy a few detail shots with more pics in the gallery below:

Engine Bay

Devoid of unnecessary bits, the Rebello 2.3 with dual-Mikuni’s takes center stage:

 

Interior

 

A tribute to the B-Sedan racing 510s of the 70’s, the interior is spartan with a simple dash, roll cage and OMP seats:

 

Again, it’s super sanitary in here with subtle color choices and straightforward switchgear. That is Pete Brock’s signature on the dash!

  

Body

The 2017 Corvette Racing Yellow paint is loud, but in a good way. Mark’s touches here are an exercise in restraint, while harking back to the Trans Am racers he remembered. The white roundel was inspired by our friend Dave Scholz’ Datsun 240z as seen on Petrolicious . 13″ re-pop’d (VTO) AR Libras are the definitive wheel choice here, with contrasting black spokes and chunky Toyo R888 tires:

 

Sorting at ZCG

 

The 510 was constructed with both Mark’s skillset and Troy’s finishing touches. After he finished his project, Mark visited ZCG for adjustments and sorting.

 

ZCG CV Axles!

 

We upgraded Mark’s standard half shafts to our Z Car Garage CV Axles. These CV axles help transmit power to the ground and ensure smoother operation compared to standard half shafts, while eliminating the need for aluminum adapters.  Mark got ZCG VV Axle set #320 and he loves them:

 

Nick about to install the new CVs:

 

Standard half shafts (left) and ZCG CV Axles (right). Note all of the powdercoated suspension parts:

   

Getting Mark Back On The Road

 

Mark was experiencing a re-occurring high water temp issue. Finally the head gasket was compromised so we pulled the engine for a refresh.

 

We re-intalled the the engine and tidied up the engine bay. The electric fan was removed and a fan clutch installed utilizing a 620 water pump/S30 fan blade to make it all fit behind the Koyo radiator:

 

Dyno Tuning

On the dyno, we had a case of deja vu as Mark’s 510 is almost similar to Keith’s. Rob is familiar with tuning the L-Ser-es engine in both race and street 510s. Mark’s Rebello 2360 put own 189hp/178tq to the wheels, gaining 8hp/10tq with Rob’s tuning. You can hear it scream in the video below. Mark will re-visit us for another dyno session after he accumulates more miles.

 

Enjoying The Ride

 

With a few more minor tweaks like door locks and windows, Mark was out and about with his 510. He joined us at the local Fuel Supply Cars and Coffee:

 

Enjoy this video of Mark’s 510 in action:

 

We even spotted Mark at Driving While Awesome Morning Motors:

 

 

Do It In A Datsun

 

I was fortunate to catch up with Mark and meet his son Dom who also has motorsports background. It was rad to see the Datsun being a family affair and Mark all smiles behind the wheel:

 

 “I feel very lucky to be part of the Z Car Garage family. The staff are  all great guys. I will continue to bring the car in for Anything it needs.”

 

Big thanks to Mark for letting us service his 510. We really enjoyed having the 510 in the shop!

 

Speaking of Love for The 510…this weekend 20+ B-Sedan racers will be running at Laguna Seca. I will have a full report for you, stay tuned!

On July 10-12, the Classic Sport Racing Group (CSRG) hosted the David Love Vintage Races. Our favorite feature race was the Group 8 class with 20 sedans battling at Sonoma Raceway. It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with in-car footage and photos from contributors Kurt Boden, Trent Barr, Nick Dockery and ZCG Crew Nick F and Josh C.

Z Car Garage Supports Three Datsun 510s!

 

2020 has been a strange year and we were fortunate to be racing again at Sears Point in the David Love event. Z Car Garage both participated and provided support for several Datsun 510 race cars.

Here is a video with sights and sounds from the paddock, samples of in-car footage of Rob Fuller, Tom Dockery, Glenn Chiou and Mike Anderson:

 

#7 Rob Fuller

ZCG owner Rob Fuller, Bay Area Datsun Dealers tribute car

    

Rob Fuller has not been in the Bay Area Datsun Dealers 510 since last year’s John Morton Cup. This car was purchased from Larry Oka as an IT car, slowly transforming into a B-Sedan. We sorted out the front suspension and this time the rear was attacked. From Rob:

“We installed the weight jacker set to adjust springs for ride height and a DP Racing sway bar that has the same design as the BRE car. Since the shop was slammed and customers come first, we enlisted our friend and fellow racer Troy Ermish to dial in the rear setup. Josh did final prep on the car and we were ready to go. The car did awesome with the back end of he car making all the difference in the world: instead of hopping around uncontrollably I was able to feed it throttle and negotiate the car in/out of corners. We went from middle to front of pack with Troy and the fast friends from RacecraftNW. Good times.”

 

You can see footage of Rob in the second race here:

Here is a great video with multiple angles showing Rob battling with Steve Walker (BMW 2002):

 

#7 Kelvin

 

Let’s talk about our clients. Three weeks before the CSRG event we got a call from Kelvin and he was testing his 510 that he just got from a local shop. It was sputtering and running poorly and by chance Larry Oka was also testing and referred Kelvin to us. We got him on the dyno and the engine failed. With a quick call to Rebello the engine was sorted, installed back in the the 510 and we handled all the prep work to be ready for the race weekend.

 

Kelvin had a successful race experience, finally:

“Kelvin has dealt with some issues on the car and this was the first time he had a good time with it. We were really happy for him. That’s why do this: we want more people at the race track driving, not fixing. It doesn’t allow to you to build confidence as a driver. You need to have a car that is reliable and works well so you can focus on you as a driver. Kelvin was super pumped. On test day I drove both Kelvin and Tom’s cars and they are fantastic examples of what a B-sedan can be. All they need to do is knock those numbers down”

 

Stay tuned for a full report on Kelvin’s 510. His friend Ed M was so impressed with our work that he wants ZCG to prep his sedan as well. Look for full report soon!

 

#72 Tom Dockery

Tom Dockery drove his  Ex-Norm Balzer 510. This car made its debut in May 2019  and we are excited to share its full story and profile Tom’s journey into racing soon.

   Tom’s 510 has an FIA engine so it revs really high making it peaky and hard to drive. Per Tom’s suggestion, a shorter gearset would put him in the powerband and sure enough…always listen to your driver! Tom really got faster and it was great seeing him out there. Car has been flawless.

 

510 Friends!

Many notable Datsun 510 racers were in the group, all sharing the competitive spirit.

#33 Glenn Chiou

Glenn drove the Ex-Finn/Harris U2.5L Trans-Am ’68 510. This car made its debut in May at the SVRA event at Laguna Seca. Glenn did an admirable job (as always) getting this historically significant 510 back on the racetrack!

ç    

Glenn was fast. He charged all the way to the front of the pack, only seconds within Jim Froula and Rob. In-car from Glenn:

 

It is also worth noting that Glenn is one of the few “privateer” racers in the field. He sets up his own race car in his garage and his crew are friends Erich and Lloyd. We want to congratulate Glenn on the birth of his son! Kudos for racing and being a father!

#38 Troy Ermish

Troy is a phenomenal driver. He helped set up our 510 rear suspension too:) Watching Troy wheel his blue 510 his a thing of madness, finesse, skill and beauty. He took 1st place!

 

#52 Jim Froula

Race car driver and restoration specialist Jim Froula of Racecraft in the Ex- Harry Stewart Datsun 510. Jim was kind to let us pit with his gang. He’s also a fierce competitor.

  

David Love race results can be seen below:

 

A Memorable Racing Event

 

It was so wonderful to share this experience with our friends and CSRG family. We look forward to another B-sedan event and special shoutout to Troy Ermish, ZCG crew including Nick F, the Corwins Josh and Keith. Running all of the cars above would not be possible without them. Rob is excited for future events:

“Of all the vintage racing I’ve done and been around, the B-Sedan group is where it’s at. It’s competitive, fun and you always have someone to race with. We will attempt to do this again August 8-9 at Laguna Seca. Glenn and I are gathering ~25 cars!. Look for B-sedan to become one of the featured groups with CSRG, SVRA and even HMSA/RMMR!”
