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.

 

Datsun Z Family

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:

 

Performance to Stand the Test of Time

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!

Mini Z

 

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!

 

Updates and Upgrades

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.”

Dyno Tuning

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!

Power gains you can feel!

“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!

 

Enjoying The Ride

 

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:

Long Live The 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
