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:

 

EVENTS: The ZONC Annual Car Show

Happy New Year!

Bayline Vintage Meet Pictures!

EVENTS: Driving While Awesome Cars n’ Coffee 11/10

EVENTS: Cars and Coffee at Canepa Motorsports

2014 Silicon Valley Auto Show Pictures!

Bayline Vintage Meet Pictures!

 

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

Ready to Rally: Ken’s 1971 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Parts,Performance
by Alvin G @ 7:28 pm on December 4, 2020

 

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.

 

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.

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!

Dave L comes from Carmel Valley and he visited Z Car Garage for suspension upgrades on his 1972 Datsun 240z. Prior to meeting us he added many parts to the car himself like a 5-speed transmission but needed our expertise for Z-specific parts. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with a dyno-tuned 2.8L L-series really transformed this pretty S30.

 
 

Suspension

 

The chassis was treated to a full suspension rebuild with new parts and bushings from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

Stock vs T3 T/C rods up front:

 

Stock rear lower control arms were replaced with T3 adjustable units:

 

Dave provided us with a set of Tokico/springs from back in the day. We installed new tie-rods, Nissan ball joints, rack bushings, bump stops and moustache bar bushings:

Brian’s 1973 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 3:33 pm on October 18, 2019

 

Brian P hails from Canada and lives in the Bay Area with his family. We met him in 2014 when he visited ZCG for minor sorting and upgrades on his pretty 1973 S30.

 

Attention to the engine bay included changing all fluids, new motor mounts, upgraded alternator and a fresh Koyo racing radiator:

 

Rob dyno tuned the stock, SU-carb’d L24 before and after the addition of our ZCG exhaust using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip. We saw gains of 13hp/5tq and improved power throughout the mid-range:

 

Brian returned in 2016 for suspension upgrades. We installed 5-way Tokicos, Suspension Techniques sway bars, Techno Toy Tuning adjustable rear lower control arms, TC rods, and rack bushings.

 

Everything was powdercoated black and we zinc’d all hardware. With fresh bearings and a few more new suspension parts he was out and enjoying the Z.

Panasport Wheels

Complementing the new springs and shocks on Brian’s Z are Panasport wheels! We replaced the old-school Western Turbine wheels with 16×7 Panasports and Hankook R-S3 tires in 225/50/16.

Bottom left picture from Brian:

“This was taken on the day I picked up the car from the PO, a retired writer in Oakland, who only sold me the car after a 3 hour interview/visit 2 weekends prior, before the car was officially ‘for sale’ (I felt like I was being vetted as the car’s next custodian).”


 

Here is Brian Enjoying The Ride in his Z at last year’s Rolex Monterey Motorsports Reunion at Laguna Seca:

ZCG Big-Brakes and CV Axles

After a few years of driving, Brian came back early this summer for more upgrades. We handed him the keys to “Mrs. Butters”,  our 1970 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 🙂

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 Brian’s stock brakes and installed our ZCG Big-Brake kit.  We also took his Tokico 5-ways in trade for a full coil-over (Koni) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 

ZCG Big-brakes and T3 coil-overs replacing stock setup:

   
 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained! T3 coil-covers also installed:

 

Brian really wanted the look and feel of Mrs. Butters Z so we obsessed over ride height until we got it exactly where he wanted it. The Z looks fabulous from any angle:


 

 

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 70 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 
 

Stock half shafts (L) and ZCG units:

 

More pictures of the ZCG axles installed, also visible are the T3 control arms and ZCG exhaust system:

 
 
 

Driving is Believing

Brian was impressed with the ZCG Big-Brakes and how well they work: like having late model brakes on a vintage car!

“The brakes are amazing. I push the car hard on weekend drives on the Peninsula, normally taking different routes out to Alice’s, now without any fade or fear (except from passengers).”

 

With suspension and drivetrain sorted, Brian had a few remaining things on his mind. He reported a heavy fuel smell in the cabin so we replaced all of the vapor hoses to the fuel tank and installed a new hatch seal:

 

Finally, his hood had little specks on it so we had our man William repaint and blend it.  Icing on the cake: Rob installed a NOS “Datsun” emblem on it after adjusting the hood.

 

Enjoy this short video of Brian’s Z:

 

 

We enjoyed working with Brian:

“Rob and team are the best, and the only shop that will ever touch my car. I have supreme confidence that my expectations will be always be exceeded, and Rob’s enthusiasm is infectious. On a lighter note and as a Canadian transplant down here in the Bay Area, it’s a pleasant surprise to find someone who doesn’t feel the need to insert ‘ice’ before saying ‘hockey’.”

Thank you for entrusting us with your S30, Brian. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!
