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.”

Z Car Garage Big-Brakes

  

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

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. Enjoy these pictures of Jason’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. Jason successfully installed the BBK on his Z with PitstopMotorTuning, and they look great behind both the Work Equip 03 and 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. 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!”

Mike R acquired this gunmetal (KH2) 1991 Skyline GTR from Toprank International Vehicle Importers in 2019. Z Car Garage is familiar with the Norcal Skylines group and fellow R32 owner Kurt W referred Mike to us in addition to an endorsement from Top Rank. Mike’s first round of upgrades included a Project Mu Big-Brake kit, Ohlins coil-over suspension, Haltech ecu, Greddy FMIC, sorting and dyno tuning. All of this work is documented in our 2020 blog post:

   

More Upgrades

 

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

 

Add More Boost

 

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

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

 

(Below)Borg Warner EFR 8474 0.92 with T51r mod and Full Race T4 twin scroll Exhaust manifold:

 

Remade in USA throttles and Nismo plenum. Fully built cylinder head with GSC S1 cams, SuperTech valves, springs, retainers, guides:

 

PRP crank trigger kit, Radium Dual Catch cans, Custom Intercooler piping with Tial q50 bov and Nismo oil cooler:

 

HKS Super Turbo Titanium exhaust:

 

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

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

Dyno Tuning

 

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

  

Mike was pleased:

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

 

E85 Fuel

 

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

 

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

 

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

 

Enjoying The Ride

 

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

Congratulations to our client Dan F on achieving his personal goal of sub 1:40s lap times at Laguna Seca in his Nissan 350Z. Z Car Garage has worked with Dan for several years to fine-tune this Vortech Supercharged Z33 so he enjoy it on the track.You can see the build history HERE:

Chasing 1:30s

 

Dan is an avid track-enthusiast and we love working with him to optimize his Z. Let’s hear about his triumphant ‘Seca experience from November with SpeedSF:

“It was a very satisfying weekend at Laguna running both Sat & Sun 11-25/26. I came still looking for sub 1:40’s with my best time to date a 140.1. It’s only the second time I’ve been there since the re-pave but I have been running here testing and tuning for over a dozen years now. 1:39’s however have always been elusive so when in my second session on Saturday morning, I finally broke through and did a 139.2 on 1.5 year old Toyo RR’s (red wheels in the pics), I was ecstatic. That was apparently just some foreshadowing for the weekend. By day’s end I was consistently running low 1:38’s. The track is faster than it’s ever been with extra run off at T5 & T9 and a smooth surface that has now been rubbered in nicely and the weather was perfect around 62 with zero moisture.”

 

“My plan Sunday was to try some pirelli scrubs (black wheels) from the World Challenge Series. I was excited to try them on this car because it is set up as a race car at this point so it makes sense real race rubber might work well, it did. First session I blew by the 1:37’s and finished with a 1:36.1, next session 1:36.0 then finished with my best being a 1:35.8 on a lap compromised by traffic. Scrubs were good for 2.4 seconds over the RR slicks. Some pretty unbelievable gains all weekend and especially with these tires.”

 

“Still can’t quite believe it took me about 4 years to go from 1:44 to 1:40 and only 2 days to drop the next 4+ seconds but it’s days like this that make you want to keep trying for that perfect lap. Sometimes all the stars align and I’ll be looking to match my optimal lap of 134.8 next time out…”

Enjoy this in-car video of Dan’s fastest lap time in the Z:

Recent Updates

Dan’s Z received a few updates to the interior and aero package. Extensive caging inside, new front splitter and rear wing:

  

We are super stoked for you Dan! Get that 1:34 at ‘Seca and LONG LIVE THE Z!

 

The shop is busy dyno tuning, servicing and upgrading Z cars. Enjoy this brief update from Friday, December 15th.

Z Car Garage specializes in dyno tuning of vintage cars and this includes non-Nissan/Datsun classics. From establishing a baseline on street cars to preparing race cars for high-profile events we love helping each client achieve the best performance possible. Geoff W’s 1972 BMW 2002 came to Z Car Garage for a dyno tuning session with fantastic results.

 

Geoff is a friend of the shop with a great story behind his love for all things engineering and automotive. Let’s hear how he got into cars and acquired the BMW 2002…

Generations of Car Enthusiasts

 

“My father owned Formula Fords growing up and has owned a Lotus Elan since 1977; we spent a lot of time in the garage together in my formative years. I was exposed at a young age to AutoX and vintage racing I distinctly remember falling in love with Lotus Sevens and B-sedan cars. When I was of driving age, I purchased a 1985 Mk1 Toyota Mr2 (Chassis code AW11) and began to do a lot of track days and AutoX. This eventually led to another 4age powered car: The Toyota Corolla GTS (Chassis code AE86). I was going to college in southern California at the time and was involved with Club4ag.com which started holding drift day events. This was before professional organizations such as Formula D came about.”

 

“As a poor college kid, I started working drift events and track days in exchange for track time. I eventually became an instructor and won one of the earliest US drifting competitions in my largely-stock, daily-driver Corolla. After school, I bought a Caterham 7 Super Sprint, and while it was fun, it was never quite the original Lotus Seven I pined for. I eventually sold all of my “fun cars” to fund a house purchase in San Jose. After a few years, I finally acquired my Lotus Seven in 2013 as a tired vintage race car from Texas. I built a road-going motor and installed a synchromesh transmission for the car and finally got it running a year later.”

 

“I’ve been enjoying driving and developing it in the years since. Alvin from Z Car Garage and I met a few years after this car was finished and we became fast friends. Some of my best memories with this car have been spent driving in the mountains surrounding San Jose with Alvin. I’ve done a few vintage car rallies and been on track with it, but I eventually would like to do some vintage racing.” (See Geoff’s Lotus 7 in this excellent Petrolicious feature HERE)

 

The Inka Orange 1972 BMW 2002

“In 2018, I sought out a B-sedan road car to take on vintage car rallies and have something fun to drive in inclement weather. Alfa GTV’s, Datsun 510’s were out of my price range and I couldn’t find any Mk1 Ford Escorts/Cortinas for sale. I began looking at BMW 2002’s; I especially liked them in bright/interesting colors popular in the early 70’s.”

“When I bought this car, the previous owner didn’t know much about the engine. It had a pair of Weber 40dcoe’s, ran well, and seemed to feel like other stock bmw 2002s I had driven. I haven’t made many changes to the car, but did locate and install a set of rare and period correct Campagnolo wheels. Earlier this year, I found and purchased a Mk1 Cortina and I was going to sell the BMW 2002 because it wasn’t as exciting to drive.”

 

Dyno Tuning

 

The 2002 baselined at 99hp/114tq and after tuning put down 129hp/127tq at the wheels! Let’s hear from Rob…

ROB: “Being around so many B-Sedan race cars I wanted to see what all the hype was surrounding the BMW 2002. I started talking with Geoff about trading one of my S30 Z cars for his BMW. He kindly lent it to me, and I drove it to the Monterey Historics to root on our friend Jim Huff in his Neu Klasse BMW. First impressions were that it was anemic and the dyno confirmed this. Full-throttle was compromised so it needed throttle-linkage adjustment plus timing and jetting. It really came alive making great power…“

 

Enjoy the video below to see Geoff’s BMW on the dyno, test driving with Rob and enjoying a few road rallies:

Hold on to that 2002!

 

Rob and Geoff recall how they felt about the 2002 post dyno tuning and test driving:

ROB: “With +30hp/13tq this BMW was born again, and man did I like the German 510. Love the visibility, greenhouse, seats, thud of the door closing. Despite being a die-hard Datsun 510 guy I really dug the 2002. Enjoyed it so much that I thought maybe this was going to be my first German car. I drove it, Meghan drove it, and just as I was getting excited, (un)fortunately Geoff finally drove it…our improvements to the car convinced him to keep the 2002.”

 

GEOFF: “I hadn’t even considered having it tuned, but Rob suggested giving it a try. When I drove the car after Z Car Garage worked their magic, I was absolutely floored. It is a completely different car now, gaining 30 horsepower and this was not the “stock” 2002 I had assumed it to be. I’m absolutely kicking myself I didn’t have it tuned by Rob earlier. Needless to say, I am no longer interested in selling it. I feel like I’m experiencing a whole new car I cannot thank Z Car Garage enough!”

On Datsuns:

 

We introduced Geoff to the magic of the Datsun S30 Z car after joining him on local mountain drives and rallies. He gets it…

GEOFF: “Being around the shop, I have an even stronger strong appreciation for both 510’s and Z cars. I was recently given the opportunity to drive Mrs. Butters and was completely blown away by the Z Car Garage Big Brakes. I have never felt brakes like that on a vintage car; they’re more impressive than most modern cars! The sound of that L-series on triple Mikuni’s is absolutely intoxicating. While I’ve always preferred smaller/lighter 4 cylinder cars, a S30 tuned like Mrs. Butters is definitely on my short-list of next cars to own. It also helps to have a reputable shop so familiar with these cars in the area!”

 

Friendship

ALVIN: “It really is a small word. Geoff and I both work at the same company and didn’t meet until we saw our beloved vintage cars featured in Petrolicious. Since then we’ve enjoyed Bay Area backroads and beyond. Good times from running rallies with Driving While Awesome, to attending race events and weekend blasts. Geoff is truly someone I’d wish I had known earlier in life. Here’s to more memories and drives.”

 

Just a few events we have enjoyed with Geoff over the years, with more photos in the gallery below:

EVENTS: Cars and Coffee with Driving While Awesome!

EVENTS: Super Drive Sunday

EVENTS: DWA Rally From Home South

 

ROB: “Happy to help Geoff sort out his BMW. He’s such a great car enthusiast and friend to the shop, myself and Alvin. Wonderful 2002. B-Sedans are not just Datsun 510s, they are in the form of BMWs, Alfas and other marques!”
