This 1971 Datsun 240Z has a long history with Z Car Garage. We have known owner Rob J since the early 90s, having worked on his previous Z cars, and with a few ZCG touches this Series 1 continues to impress. Let’s take a look at how Rob J got into Z cars and what makes this one special.
When Rob J was a kid, his dad bought a 1971 Z (photo below) and used to cruise the Santa Cruz mountain roads with Mom in the passenger seat and his two brothers and him sitting on the luggage deck with their feet tucked under the seats:
“His idea of fun was to chuck the car into turns on Hwy 9 or Skyline Blvd – causing the 3 of us to squish into each other with the G-forces. I fell in love with the look and sound of that car when I was 5 years old and was determined to have one of my own. When I was about to turn 16, my brother crashed that car and Dad sold off the wreck, so I never got to drive it. Nothing “sets the hook” like being deprived of something you really want and I bought my first 240Z as soon as I could save up the $3500 that decent cars were going for in the 80s. I’ve had Zs ever since”
His first car was a ’71 that was stolen and crashed beyond recovery by thieves. The second, an Iris Blue ’72 (above right), was his daily driver for more than a decade and gradually benefited from ZCG upgrades. When Rob J had the opportunity to buy Paul Hooks’ S30 he sold the Iris Blue Z car to Tony K.
“When Rob Fuller first came to California to work on Datsuns, we had a regular gang of Z drivers going to track days together. The illustrious Paul Hooks was a fellow track nut and this Z was his car. He had done his restoration and modifications the right way – as a closely spaced series of coordinated upgrades using the best gear available, and the car always impressed me with flat cornering, powerful breaks, and that throaty 3.1ltr engine. So when I eventually had an opportunity to buy it from him, I jumped. “
Rob J with the Z he’s longed for:
Paul Hook’s Z was built in the late 90s/early 2000s, so it has the very same 3.1L L-Series engine with triple-Mikuni induction backed by a 280zx 5-speed and R180 LSD. Period suspension upgrades included 5-way Tokicos w/Eibach springs, ST f/r sway bars and sticky Advan A032R tires (remember those?!). The interior has a roll bar with harnesses, Recaro seats and rear strut tower bar.
The ethos of this build was centered around open track day events that Paul enjoyed. Increased braking performance was achieved through a 4-wheel Porsche 911 Turbo “Big Red” caliper brake kit. It works pretty well, but not as well as our Z Car Garage Big-Brakes with respect to pedal feel/un sprung weight…all benefits from our years of experience and collaboration with Stoptech engineers.
What makes this Z special? It was built in a period where Z cars were not deemed “collectible” or valuable yet. Despite this, we were building high-end Z cars that performed really well on the street and track. Perform on track indeed; for a car built nearly three decades ago Paul’s vision and execution is impressive. He was a track hound and this Z was his tool of choice, calling routine track days “high-speed mediation”.
This ’71 being a Series 1 offers the lightest S30 chassis and paired with 191whp (modest by today’s standards) from the 3.1L it’s tremendously rewarding. It makes all the right noises too, just listen to Paul blasting down the front straight at Thunderhill Raceway (video below) in both rain/dry conditions!
Paul’s Z was special to many, including myself. It was “the one” in my eyes seeing how it did everything well from track days to cruising around…the epitome of balance in the S30 chassis. I admired it so much that I made a 1/24 scale model replica with loads of details based on hundreds of photos I accumulated over the years. In 2008 while attending a ZCG Dyno Day I finally presented the model to Paul. More pictures in the gallery below!
So what does this already well-sorted Z need? We discussed a list of needs/wants with Rob J…including sticky tires, new exhaust system to ZCG-spec, and a transmission upgrade. The aged Hankook R-S3s were replaced with Bridgstone RE-71R in 225/50/16 over those classy Panasports:
The 280ZX close-ratio gearbox that Paul had was getting old and noisy. At the time we were doing Nissan KA24 (FS5W71C) transmission swaps (before the CD009a came to market) by modifying a 280Z L-series bell housing. You can see the custom ZCG transmission mount below.
A JWT heavy duty clutch and Z32 shift knob finish the swap in style.
The Z had a really old-school Crane HI ignition components. We updated to run the MSD box so Rob could tune the car and extract a little more power. The exhaust was replaced with our ZCG exhaust system and a Koyo race radiator installed.
Rob J was happy with the updates:
“Recently, I took my car into the shop for an exhaust system upgrade and electrical system maintenance. What I got back was a different car entirely! Rob and the crew replaced my old school exhaust, which was frankly an eyesore, with ZcarGarage’s current system, which is expertly tucked up into the undercarriage and finally really looks the part. The exhaust isn’t louder, but it’s more sonorous and less tinny sounding. I love it.”
It has been many years since this Z had been on our dyno. We adjusted the valves, set timing, sync’d carbs and re-jetted them for the new exhaust. Baseline was 198hp/194tq and after Rob’s tuning the Z made 222hp/213tq at the wheels. More power even after all these years this Z does not disappoint!
“The improvements are awesome: approximately 25 more HPs and 19FtLbs and much smoother power delivery. The car leaps down the road when you mash the throttle and no longer stumbles when rolling into the throttle from cruising RPMs. The car was fun before and now is just crazy fun.”
Enjoy the dyno video below as well as some historic footage of this Z in action. Volume up!
We love how Rob J is enjoying his Z, just as Paul Hooks did. Rob has attended many events and fun runs and I still can’t take my eyes off this Z! In case you are wondering, his plate reads “Kenjuru” to note the martial arts he practices 🙂
Below are just a few of the great times we’ve enjoyed with Rob J and his ’71 Z:
Plans for the future…we will continue to keep this Z on the road and give Rob J updates like our Z Car Garage Big-Brakes, and Z Car Garage CV Axles.
“This 240Z is a late Series 1 manufactured in December 1970, so it’s not a low VIN car (17,XXX) and I don’t feel any pressure to restore it to stock. Instead, we’ll keep upgrading the go-fast options while keeping a vintage look. I truly love driving this car on the street and the occasional track day and I love doing both with other Z Datsun enthusiasts.”
Thank you Rob J for supporting us and being in our life. We are so happy you found the right Z and ZCG will always be your home! DO IT IN A DATSUN

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.
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:
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.”
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.
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.”
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!
