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.

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.

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:

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.”

 
What’s in store for Jason’s Z?

“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!”
