All of these parts were developed on Mrs. Butters to offer our clients a balanced performance package. Enjoy the article with photos and interview with Rob Fuller by photographer Naveed Yousufzai HERE.
We met Ken W last summer when he stopped by Z Car Garage to meet Rob and have his S30 inspected. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with upgraded suspension parts and a Rebello 3L engine transformed his 1971 240Z into a fantastic sports car.
The Right Z
Before we dive in to the upgrades let’s take a look at how Ken got into Z cars and finally found the right one…
“When I was a junior in High School, the cool kids were driving Mustangs, Camaros, and ‘Cudas. Always different, my imagination was captured by the ’71 Datsun 240z. Being a Kansas farm boy on the lower end of the economic scale, had to settle for a ’64 Ford Fairlane 500 4-door with the 269 V-8. Knew that someday I’d own a 240z. Spent 2018 researching the 240z market. In January 2019, bought a red ’72 240z with Wilwood brakes, QA1 coil-over suspension, 17” wheels. A little rough but convinced me that owning a 240z as a daily driver, was going to make me happy.”
We inspected Ken’s red ’72 240z and found many problems. Rob suggested finding a chassis in better shape to make his own. After our evaluation Ken consulted with fellow S30 owner/racer Glenn C to affirm that ZCG was the right place to be. Ken was convinced that the S30 is a great rally car and began searching again, finding this green ’71 on Craigslist, near Sacramento.
“Rob gave this car his approval as a basis for the rally car that I wanted to build. ZCG is so popular that we weren’t able to get it in for the chassis upgrades before the Mother Lode 400 rally in June 2019 . The car was fine, but only fine. Yes, the brakes and suspension worked and the motor was dependable, but with the enthusiastic style of rally driving, showed they really weren’t up to the task.”
ZCG Big-Brakes and CV Axles
The upgrade process began, giving Ken the ability to brake on a dime, perform well and daily drive. We handed him the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂
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
Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.
A few closer detail shots of the calipers, rotors and hardware:
We removed Ken’s brakes and installed our ZCG Big-Brake kit. The Z also received Tokico 5-way struts with Eibach springs and suspension parts from Techno Toy Tuning. New parts included adjustable T/C rods, rear control arms, new bushings, rack bushings, steering coupler, factory Nissan ball joints, new wheel bearings and more. We really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

T3 T/C rods and new brake master cylinder/booster:
Suspension Techniques sway bars installed front and rear:
At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality retained! Ken was pleased with the brakes:
“I really the brakes. Having experienced stock brakes and the Wilwood’s (Stage 4 front and rear), was really interested to discover if the ZCG Big Brake kit was all that I’d heard about. I’m here to say that the Big Brake kit exceeded all expectations. Under hard braking, feels like I’ve just driven into a huge pool of thick super glue or that someone immediately behind me has just switched on a huge electromagnet. Undeniably shorter braking distances. Huge confidence when diving deep into corners.”
Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. Ken’s Z received set #298. We have over 100 CV axle kits on customer cars and we are stoked with all of the positive feedback.
Stock half shafts and control arms (L):
Before/After suspension upgrades. Not shown is the ZCG exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip:
Great feedback again from Ken regarding the suspension upgrades:
“In August 2019 it went into ZCG shop for the upgrades. Let’s talk about the suspension first. My red ’72 had QA1 coil-overs and it wasn’t particularly balanced or optimized. Too soft in front, too harsh in back, little squirrely under brake or gas. By comparison the ZCG components showed care in selection, thought in design and clear goals in creation of a balanced package. The car is impressive under braking, squatting uniformly and smoothly. Under hard acceleration, it tracks straight. The CV axles are works of art and well suited to handle the Rebello motor to come.”
More Power
With braking and suspension sorted all Ken needed was power to match. Without going too wild we opted for a Rebello 3L, retaining SU induction. The 3L still leaves room for aggressive cam/Mikuni induction upgrades should he feel the need. A few pictures of the fresh motor, more in the gallery below:
Ken enjoys tinkering with vintage motorcycles and rallying. While running the Snowball Rally the car did really well and he had a great time but unfortunately, it was hit by a motorist (not part of the rally). We called upon our man William from William’s Auto Body to fix everything and re-spray.
While the motor was out, we cleaned up the engine bay. Everything came out, the bay was painted, new seals around all hoses going through the firewall. The engine got an MSA 6 to 1 header, all intake/exhaust gaskets, MSD6Al box with tach adapter, Koyo race radiator, zinc’d hardware and new alternator/starter. We ensured that he would be able to rally wherever and whenever.
Backing the 3L is a 5-speed with JWT aluminum flywheel and Exedy clutch:
Rob dyno-tuned the Z with the stock L24 (109hp/128tq) and the 3L, now making 199hp/209tq to the wheels:
Enjoy the L-Series music!
Panasport Wheels
What is the perfect companion for Ken’s Z, now that it has full suspension and wicked brakes and fresh paint? Panasport wheels! We replaced the old-school slotted wheels with 16×7 Panasports and Bridgestone’s killer S-007a tire in 225/50/16.
“The Wilwood Stage 4 front brakes required a spacer to move the generic Japanese front wheels out far enough to avoid fouling the calipers. This meant running 215/45/17 tires. A drawback to the 17” wheels is that the space-saving spare can’t exceed 16” in the spare tire well. I totally love the beautiful Panasport wheels! When I take the car to Z car meet-ups, everyone says “this car has been to ZCG, right?” The wheel and brake combo means I gained 10mm tire width and no spacers. We agreed that for rally purposes, I’d change the tires every 3 years, so Rob picked out some nice sticky ones.”
Rallye On!
Ken was smiling ear to ear and told us we built him a Z car he really enjoyed:
“The results are fabulous! My car is such a hoot to drive. Quick off the line, easy to spin the tires. Now I understand why Rob recommended the CV shafts. The car was awesome on the 2019 California Melee. Had so much fun driving the rally with my brother who flew in from Kansas. He drove it much slower than I did, so when I took my first shift, diving it deeper and deeper into the corners, accelerating harder and harder out of the corners, that I proposed establishing a safe word if he wanted me to ease off the fun.”
We have been checking in with Ken and he’s happily Enjoying The Ride. We even spotted his Z cars while cruising through the neighborhood.
“I’m so happy to have met Rob and provided him with a car that has ‘good bones’. Enjoyed working with ZCG. A key for me is that ZCG has been able to provide all the upgrades, in an integrated package. Didn’t want to use multiple shops and fight through finger pointing. Trust Rob and his crew, they’ve done these upgrades 100 times or more. They know what works and what doesn’t. Personally, I care more about the quality of work performed and the result, rather than shopping for the lowest price.”
Thank you Ken for allowing us to help you achieve your vision of the ultimate Z car. We loved working with you. Long Live The Z!
Happy Thanksgiving from all of us at Z Car Garage! We hope you can find time to Enjoy The Ride over the holidays. Please note our hours of operation below:
We will be closed today and Friday for Thanksgiving, re-opening Tuesday December 1. Thank you!

Our ZCG Big Brakes have been winning over Z-car enthusiasts locally and globally. Jaime recently purchased a set and performed the installation himself in his garage in Los Angeles, Ca.
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. Let’s take a closer look at Jaime’s beautiful S30 and his ZCG Big-Brake installation:
As mentioned, our ZCG Big-Brake kit ships with everything needed to install and retains the factory parking brake:
If you follow Jaime on his Instagram page its clear that his attention to detail is impressive. He successfully installed the BBK on his Z, complete with functioning parking brake:
Front and rear:
Easy fitment behind his 15×8 Watanabe (zero offset) 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. Jaime was very happy as well with great feedback:
“The brakes are a complete game changer. Money well spent”
A Beautiful Work In Progress
This is Jaime’s first vintage car to work on and his goal is to have a reliable daily driver/occasional track machine. Under the hood is a ported/polished L24 with Spirit Garage R header, triple-Weber carbs tuned by Kyushahousetaka, Fujitsubo Leagalis R exhaust and our very own ZCG Heat Shield.
He’s been Enjoying The Ride (and braking with no worries)
The chassis was treated to a full coil-over suspension and many more parts from Techno Toy Tuning
We really like Jaime’s aesthetic with the 904 Kilamanjaro white against the gunmetal Watanabe wheels, JDM tails, 432 grill, xenon bumper w/Skillard lip and JDM fender mirrors:
He also installed a Vintage Dashes unit and reupholstered the seats:
Keep up the good work Jaime and we are very proud to have our Big-Brakes on your Z!
Stay tuned for more customer installations of our ZCG Big-Brakes! Check out our ZCG CV axles HERE.
Long Live The Z!

Andreas visited Z Car Garage to get his 1983 Nissan Skyline running correctly. We admire these 80’s gems, working on several DR30 Skylines and with a few tweaks plus dyno tuning Andreas was back on the road in proper form.
The Sixth Generation
Not familiar with this right-hand drive specimen? Most Americans are familiar with the classic 70’s Skylines and later GT-R series, but this 6th generation (R30) chassis is often overlooked, yet very special in its own right. Andreas’ model is a ’83 Nissan Skyline RS-X and it’s the first iteration of the distinctive “Iron Mask” front end. This generation also marked introduction of the FJ20 engine, though Andreas’ is an early, non-intercooled model:
In Japan the R30 sold well and had a great following with Nissan enlisting the famous actor/racer Paul Newman to appear in ad campaigns. The R30 also formed the basis for the insanely cool SuperSilhouette race car:
DR30 Ownership
With its angular styling, pillar-less windows, killer graphics and FJ20 power what’s not to like? Andreas had been wanting a DR30 for the past 10+ years and after driving Reid’s DR30, it motivated him to finally get one:
“With the help of The Import Guys, I purchased it from auction in June and picked it up in November in Washington and drove it straight home to Northern California. 2 days, almost 1000 miles and it did it perfectly. I have been fixing a few things here and there like a new front lip, interior trim, suspension, brakes and threw back on some OEM parts but my journey with the car is still young. I have auto-x’ed it already and do have my eyes on potential track days.”
Andreas was having problems with the car not revving properly and recalled his discussion with Reid (thanks!) about his and getting work done at Z Car Garage:
“I reached out to Rob for help. Kind of funny, on the day of the appointment to get this issue checked out my car broke down a mile from the shop and he was nice enough to help me tow it there. I have pretty modest goals, I just want a good looking, fun to drive DR30. This one has its issues like most 35+ year old cars but the idea was to get myself a nice project (but a driver). No need for a beauty queen, and no real need for massive power. Give it a refresh, and then just drive the hell out of it.”
Skyline Sorting at ZCG
Since purchasing, this R30 was not running correctly so we started troubleshooting the fuel system. We figured out some of the issues (bad fuel pump, running extremely lean, no fuel getting to motor) and we got Andreas running.
Despite new injectors, fuel filter, fuel pump we kept hitting these limiters. The factory ECU wouldn’t allow it to rev over 5krpm so we called our friends from JWT. Clark Steppler is the master of all vintage ECUs and he worked his magic on the delicate, vintage unit. As you can see from the dyno plot we have full rev range power/tq.
Dyno Tuning
Rob dyno tuned the FJ20ET, now with full power available to redline it put down 178hp/158tq to the wheels. Impressive power for the time, with a hot-pipe. Nissan really was special in the 80’s!
Enjoy this video of the dyno run and Andreas enjoying the DR30:
While the Skyline was here we replaced the front control arm bushings with new Superpro bushings:
Andreas was driving the car when he felt a loss in power. We discovered a boost leak in the hot pipe and resolved it. In Andreas’ words “No issues now and car runs like a dream.”
Enjoying The Ride
With the engine sorted Andreas has been driving his Skyline everywhere, happily boosting. Ps…did we mention how good it looks on the Longchamp wheels?
He even made it out to the recent Norcal Skylines Matsuri 2020, an event we were lucky to attend last year:
“I want a car I can have fun with and drive hard), not something that I just take to cars and coffee. So I appreciate all the help he gave me to get my car back up and running and back to its former glory!”
Thanks for letting us work on your DR30 Andreas. We love the direction you are taking it!
