Tony K’s 1972 Datsun 240Z has a long history with Z Car Garage having received upgrades like a 3L with triple-Mikuni ph44s, 280Zx 5-speed transmission, suspension refresh, our Z Car Garage Big-Brakes, Z Car Garage CV Axles and Z Car Garage Heat Sheild.
Tony’s Z has a great history that begins with our friend and fellow enthusiast Rob Julien. Let’s take a closer look.
“I bought the car from Scott Wagner — a customer of ZCG — in 2014 as a replacement for my Ducati 748 that was totaled (along with me) a few years earlier in a near-fatal accident. I figured if I wasn’t going to ride bikes anymore, I wanted to get a car that offered a visceral and pure driving experience. Clearly I picked the right car and, unbeknownst to me at the time, the right man and garage to take care of my car.”
Very shortly after purchasing the car, Tony took it on the best road trip of his life:
“I drove with my wife from San Francisco to Vancouver where I lived and worked at the time, taking Rt 101 along the coast as far as I could up into Oregon before heading inland. The car was so great – planted and confidence inspiring on the twisty back roads, plenty of power, and a great soundtrack. While I lived in Vancouver, I met a group of Italians who loved cars, and we often took spectacular mountain drives during the spring and summer months and then garaged our cars in the winter.”
During its time in the Great White North we helped Tony out remotely:
“One of the best parts of my experience with the car has been the professional service, unparalleled expertise, and honest work from Rob and his great team at ZCG. I had spoken to Rob several times while I lived in Vancouver to ask him various questions, and he treated me like a valued customer; he spent quite a bit of time listening and explaining things to me even though I wasn’t a customer, and he didn’t know me from Adam. It was very clear to me how much he loved the Z and simply wanted to help me enjoy the car as much as possible. It was great to finally meet him and his team (and of course the shop dog) when I moved back to California and witness his infectious enthusiasm in person.”
Tony serendipitously moved from Vancouver back to the Bay Area and immediately visited ZCG so we could handle everything on his wishlist. Let’s review the work we performed just before Tony left for Canada.
The engine bay was painted black so we took this opportunity to paint it body color and perform general tidying. As usual William worked his magic to match the Iris Blue Metallic body color. Before/after:
New hydraulic lines/plumbing and wiring harness cleanup made this engine bay pop
We treated the engine to several upgrades including an MSA 6-into-1 exhaust header, new intake manifold with rebuilt Mikuni pH44 carbs, JWT HD clutch/flywheel, Koyo aluminum radiator:
We also installed what every triple-carbed L-series needs: a Z Car Garage Heat Sheild!
From dirty and grimy to fresh and clean. You an also see the freshened front suspension with new T/C rods and lower front control arms from Techno Toy Tuning
Tony’s Z also got the ZCG HID kit. We performed this mod on Gary R’s 280z restoration with great results: stock appearance during the day with HID brilliance at night. These were adjusted at his recent visit.
After driving the Z all the way down from Vancouver, Tony reported the rear brake drums had failed so he had the Z towed to us from Sacramento. It was time to take care of the little things that he wanted sorted as well as some exciting upgrades, ZCG-style.
The interior got some love with repaired tachometer, fabricated fire extinguisher bracket, new shift boot, shifter/bushings, NRG quick-release to work with his MOMO steering wheel, new front/rear window seals, rear hatch seal and MSA glove box insert.
The 3.0L stroker L-Series received a full Mikuni carb tune, sync, idle speed set and velocity stacks with filters. We also cleaned up the engine bay/tranny areas.
The stroker motor produced good power with Rob’s dyno tuning. Baseline was 191hp/187tq with final results of 208hp/201tq to the wheels:
Enjoy that sweet Mikuni-carb’d L-Series music on the dyno:
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 engineers at 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 some 14″ wheels) 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 Tony’s brakes and installed our ZCG Big-Brake kit. Early in its life the Z also received Ground Control coil-overs and suspension parts from Techno Toy Tuning. New parts included adjustable T/C rods, sway bar set, 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.
Tony’s Toyota 4-Runner brakes removed and we installed our ZCG Big-Brake kit up front.
Our Big-Brakes utilize the OEM brake master cylinder and booster along with the factory hydraulic system. We replaced the M/C with a new unit, here are a few more shots of the front setup:
At the rear, the OEM drums brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!
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 100 CV axle kits on customer cars and we are stoked with all of the positive feedback.
Tony received axle set #263. Stock half shafts and ZCG units shown below with more pictures in the gallery:
Tony was pleased with the mechanical upgrades:
“I had the car towed to ZCG from Sacramento for Rob and his great team to install the ZCG Big Brakes, ZCG CV axles, new Recaros, new tires, and get a much-needed partial re-spray. The upgrades and modifications really transformed the car from really fun to drive to truly confidence inspiring, particularly because of the awesome brakes.”
After years of wear and tear the clearcoat was starting to peel on the roof (pictured below, left). As usual William worked his magic to match the Iris Blue Metallic body color, re-spraying/blending the top of the car.
We are happy to report that Tony is Enjoying The Ride. Here are a few summer pictures post fresh paint/upgrades, more in the gallery below!
“I have a few more upgrades I’d like to do on the car (a tad more power and perhaps upgrade the suspension), but one thing is for sure: there’s no one I’d rather have work on my car. But more importantly, I just need to drive the stink out of it.”
Thanks Tony for trusting us with your Z. This car has come full circle as Rob worked on it when he was 26 years old and now at 48. We are lucky to have a life filled with cool Z cars and more importantly great relationships with their owners. ZCG is a like home to them. LONG LIVE THE Z!
We love to see our products being installed and enjoyed on customer cars. Dustin is running our Z Car Garage CV Axles in his 1972 Datsun 510 4-door. This Dime is powered by a Nissan KA24DE/5-speed and wears a sweet set of NOS 15×7 Longchamp XR-4 wheels:
Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 100 sets of axles globally, with customers installing and enjoying them on everything from street cars to full-blown IMSA racers. These CV axles will help transmit power to the ground and ensure smoother operation compared to your standard half shafts.
For years we have used aftermarket CV axles that utilize an aluminum adapter prone to loosening up over time. Despite efforts to keep things tight (Loctite, hardware changes) we had to keep an eye on them. We developed a better solution that eliminates the need for aluminum adapters and remains 100% bolt-in like a factory half-shaft.
Dustin is running a Cusco LSD (Subaru STi R180) with Toyo R888 tires and worried about excessive wear on the stock half shafts, having seen multiple sets of other CV shafts come apart. He heard about our CV Axles from fellow Datsun enthusiast/racer Glenn C and ordered a set from Rob. Dustin installed the CV Axles himself on his 1972 Datsun 510 and reports that it went smoothly:
“The installation was very simple and easy to understand. I really like that they came with Red Loctite.”
We were stoked to hear Dustin report the improvement over his standard half shafts:
“The Cusco LSD is very noisy but seems to have gotten smoother and a bit quieter with the new axles. I doubt I will ever run into any issues breaking one with a KA24. I would highly recommend them as the only CV option.”
Here is Dustin’s 510 in action, enjoying the new ZCG CV Axles:
We’ve known Dustin and Courtney for many years. Hagerty produced a video featuring the local Bay Area Datsun couple you can see it HERE.
The couple got married in 2018 and Z Car Garage prepared Courtney’s 240z in time for their special day. Learn more about ZCG’s work on Courtney’s 240z HERE. Keep Enjoying The Ride, you two!
Our 1971 shop demo Z, Mrs. Butters, is now featured on Petrolicious. In addition to a 3.2L, triple-Mikuni engine this S30 proudly wears Z Car Garage Big-Brakes, Z Car Garage CV Axles, ZCG Heat Shield, 6-speed transmission and full KW suspension (releasing soon).
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.
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.”
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 🙂

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.

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.
ZCG Big-brakes up front:
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.”
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!
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.”
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!
