The Nissan 300ZX Twin Turbo is one the best Japanese sports cars of the 90’s. Keeping them on the road is our passion and we love to see our clients like Peter H Enjoying the Ride after some Z Car Garage power, chassis and aesthetic upgades.

 

Let’s take a look at how we made the already-fantastic 300ZX a well-rounded sports car, starting with Peter’s Z-story.

 

It’Z Never Too Late to Z

 

Peter was not always a Z-car enthusiast, but as we all know it there is no time like the present to own one and he acquired his Z32 from a prior Z Car Garage client:

“My experience with ZCG started back in end of 2016 when I acquired the Z from one of their former customers. To be honest, I had a very limited knowledge on Nissan Z cars before 2016 as I had a heart on rotary engine (Mazda FD RX-7) until I connected to the Z and its timeless design. I first brought my Z in to ZCG for power steering leak as the car was exclusively maintenance by ZCG and I want to keep it that way and I was impressed with the quality work of ZCG and their knowledge. Istarted to chat with Rob about the car and learned a lot from Rob about Z cars.”

 

Over the last 5 years we helped Peter with regular maintenance along with performance upgrades. Peter really wanted to give this car the attention it deserves while enjoying the occasional open track day.

Power Upgrades

 

Prior to power upgrades a few items were addressed. The 1990-1994 Z32TT’s have fuel injector problems because Nissan used a wet coil design. This left the injector coil wire prone to oxidation over time and eventual shorting. The solution? Convert to later style injectors using the early fuel rail. For Peter’s Z we wanted to run 740cc injectors which is only available in the new style:

 

More engine work including full timing belt services along with valve cover removal/refinishing:

 

Driveline was upgraded with a JWT HD clutch and flywheel. Keen observers may note that the exhaust has changed too!

 

Larger downpipes greatly improve flow over the stock manifolds. The best downpipes for your Z32TT can be found at SpecialtyZ. These are 3″ units:

 

The Z was treated to a chassis steam clean, making a clean grime-free backdrop for the new exhaust system. Downpipes were mated to 3-2.5″ SPZ mid-pipes and Greddy SP1 Exhaust:

 

We installed more parts from our friends at SpecialtyZ  like their Selin dual MAF. To improve breathing we also installed larger Stillen intercoolers and charge plumbing from Ash-spec. Managing boost is a Greddy Profec E Boost Controller:

 

Finally, low-profile engine mounts from BDE offer more turbo inlet clearance and oil temps kept in check with a Concept Z Performance full Flow Oil Cooler Kit:

 

Recent work at Z Car Garage included a repaired turbo actuator, oil plan replacement, repaired heater core, new OEM wiring harness and minor electrical sorting from a 3rd party gauge installation.

Dyno Tuning

 

We dyno tuned Peter’s Z picking up 25hp/32tq for a total of 36hp/341tq at the wheels:

 

Enjoy this video below showing the dyno run, a walk-around, take-off and brief track footage:

 

Big-Brakes and Chassis

 

As every Z32 owner knows, the stock brakes just aren’t up to the task for track duty or even spirited driving. More power exacerbates the issue and you know how we feel at ZCG:  It’s Stoptech Or Don’t Stop At All. Peter eventually experienced the difference:

“The Z was cranking out 355wHP but with stock brakes and heavy wheels. The acceleration was great but it had a big problem on stopping. I first upgraded with bigger rotors but it did not feel enough stopping power when going downhill. I brought my concern to Rob and Rob made it clearly to me Stoptech BBK is the only solution on Z32s.”

  

We installed the 332mm Big-Brake Kit using red calipers and rotors. Stock vs Stoptech:

   

At the rear, stock Z32 calipers were paint-matched to the Stoptech red up front.  Sport kit slotted rotors with 309 pads and SS lines throughout:

    

In addition to their function, the Stoptech’s look nice too!

 

A few chassis upgrades included Powertrix Front Strut Tower, Stillen Front Rear Sway Bars, SPL Titanium Tension Rods, full Tein Flex Z Coilovers and new steering rack boots/bushings:

 

Interior

 

Peter wanted us to sort out his aftermarket gauges (Prosport Boost Gauge, Oil Temperature, Water Temperature Gauge), install a new steering wheel and upgrade lighting:

    

The dim stock displays benefitted from new LED sources. Check out the difference:

 

Even the climate control display is improved:

 

More LED upgrades throughout the cabin:

 

Peter’s interior touches include a Custom Alcantara on factory steering wheel with thumb rest:

 

Recaro Speed Racing Seats with Bride Seat rail/bracket, Nismo Clutch and Brake Pedal, Cusco accelerator pedal, and custom carbon fiber interior door sill with a logo “Fairlady” :

 

Aesthetics

 

Richard W brought his 1971 Datsun 240Z from Eureka, Ca to Z Car Garage for a full mechanical restoration back in 2020. Our Z Car Garage Big-Brakes, Z Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain and full suspension transformed this Series 1 S30.

 

With a few thousand miles on the build Richard visited ZCG earlier this year for routine maintenance. We changed the fluids, resolved a charging issue, checked the driveline and overall health of the Z.

 

While the Z was with us we performed extensive road testing with acceleration, freeway cruising, dyno runs and more all shown in the video below. Turn those speakers up and enjoy!

 

I could not resist taking more photos of the engine, interior and chassis on this gorgeous Sunshine Yellow Series 1. Enjoy some photos from his recent visit and of course zcarblog has the full report on our restoration of Richard’s Z.

 

Drivetrain

 

We got the original L24 with SUs running after sitting for years, but Richard wanted more power and Rob suggested a Rebello 3.1L engine. Supporting parts included an MSA 6-into-1 header, ZCG exhaust system, internally regulated 280ZX alternator, 280ZX gear reduction starter, KOYO race radiator (custom upper hose) and Z Car Garage Heat Shield. Here are a few pictures of the engine build/installation with many more in the gallery:

 

To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. When we upgraded the transmission we also installed a JWT HD clutch with aluminum flywheel. Helping put the power down efficiently is an OS Giken LSD. The R180 houses a 4.11 R&P and the assembly is setup in-house (by Joshua Corwin).

 

Engine Bay Services

Richard’s Z received a total engine bay restoration. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine! Final Before/After in the engine bay:

 

Suspension

Richard’s chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni struts with our spring rates) 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.

 

Front Suspension refresh with T/C rod, crossmember and steering rack detail: Rear end with T3 lower control arms and ST Sway bar:

         

 

Interior

 

One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors.

  

The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:

  

Please check the gallery below for more detail shots, there are too many to list in this blog post!

Enjoying The Ride

 

It was great to see Richard again and meet his wife this time, recalling how he purchased the Z new in December of 1970! We love that this restoration is out on the road and being enjoyed. It’s also a great example of how no matter how far away you live from Z Car Garage we will help our clients any way we can. Long Live The Z!

“Richard got out of the Z and told me he had bought this Z 50 years ago that week, it’s been with him through alot of stuff and now his kids and grandkids will get to enjoy it. I looked him in the eye and said I’ll be here for their chapters, any time they need me. I’m attached to this Z now too.”

We love to see clients installing our Z Car Garage Big-Brakes on their Z Cars! This is Mike’s 1972 240Z with original matching L24. It was bone-stock and sitting for 16 years outside until he rescued it year and a half ago. Mike is a professional automotive paint technician and this Z will be restored with correct 115 metallic blue paint.

 

Client’s often ask if their wheel will clear the ZCG Big-Brakes and we offer a a caliper template to help with fitment. Sometimes it’s best to physically test fit the actual wheel desired. Mike sent us a pretty rad Star Shark wheel from Washington and we confirmed clearance of the Big-brakes:

 “I chose the Colin Project Star shark wheel 14×8-13 for some JDM nostalgia, the look, and a bit more aggressive stance. They are wrapped in BF Goodrich 225/60r14 tires. I very much wanted to upgrade the brakes with the Z Car Garage Big-Brake Kit after seeing Larry Chen’s Ole Orange Bang done by Rob and ZCG team. Sent Rob a wheel for an accurate verification of fitment, and Huzzah!! They Fit! Very, very excited about this. You can’t just put any brake kit on this car. This is a kit that you can have confidence in because the research and development has been done.”

 We are really stoked to see Mike’s restoration progress. Thanks for your support Mike and Long Live The Z!  You can see more information on our Z Car Garage Big-Brakes and see a list of clients (over 100!) using them on our blog.

 

 

Z cars may remain with their loving owners for years, change ownership or even get spotlighted in the media at some point. Our “where are they now” series features past Z Car Garage vehicles with updates on their status. In this second installment we catch up with Greg’s 1977 Datsun 280Z, now residing in Seattle, WA.

 

Z Car Garage Restoration

We met the previous owner, Greg H a few years ago at a Blackhawk Museum gathering where famed Peter Brock (BRE) was speaking. Greg told us that he found a clean, low-mileage 280z and he was really interested in ZCG going through it. After he visited the shop we discussed our previous 280z builds (Cece, Gary and the Roth’s) and got to work building a Z for Greg that would reflect his tastes while keeping the vintage vibe. This 1977 280z was treated to a ZCG-style mechanical restoration including a new drivetrain, engine bay restoration, total suspension rebuild and more.

 

You can read all about our work on this Z here HERE. A few highlights include our Z Car Garage Big-Brakes developed with Stoptech:

 

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

 

Greg received ZCG CV Axle set #264, standard half-shafts shown on left:

   

The Z received a new L31 engine with fresh 280Z 5-speed transmission. The entire engine bay was detailed with new hoses/clamps, plating and wiring:

 

Full front and rear suspension rebuild:

 

Panasport wheels:

   

Where is it now?

 

In August 2020, Greg H listed the Z on Bring a Trailer, you can see the auction HERE. The auction winner and new owner Greg J reached out to us and we’ve been in touch ever since. He even sent us this nice write-up below of his journey picking up the Z in Fresno, CA and driving back up to his home in Seattle, WA. Enjoy!

 

You can’t go back, or can you?

By Greg James

There’s an old saying about never being able to go back. In a sense, it’s true. Anyone approaching-or at- senior citizen status knows what I mean. However, with our cars, we can re-live some of our youth even If it means doing so with a bit more weight, less hair, and a more measured approach to what and how we drive. In other words a car can be a great way to go back in time. In the early 1980’s, while in college, I earned my degree from the school of auto hard knocks before getting things more or less sorted out. Impulsive car buying decisions  and – admittedly – my poor maintenance of those same cars resulted in a series of duds that ended up junked or unloaded quickly. That list included a Datsun 610, Sunbeam Alpine, Saab 99, and a Datsun 1600 Roadster. Eventually after trial and error and a couple of seized motors, I found my “road mate”: A lightly used Orange/Black 1973 Datsun 240Z. Unlike my previous cars, the Datsun was quick, reliable (By then I’d learned to change the oil), and sleek.  Did I mention reliable? I drove it for over 50K miles, and it never let me down. After 3 years of ownership I sold the 240Z and moved on to a 1976 Porsche 911S. I quickly embraced the Porsche marque and over the next several decades, bought, sold, and “drove the wheels off” a dozen 911 cars starting with the original S and up to my current pair of Neunelfers, a 1996 993 Twin Turbo, and a 1985 3.2 Carrera. During Porsche ownership I rarely looked back at – or thought about – any of my former cars, with one big exception, the Datsun 240Z. When I occasionally saw one on the road, I remembered the ‘73 and the numerous road trips I took with my girlfriend to places like Sun Valley Idaho or San Francisco. By today’s standards, the originals Z’s are primitive and underpowered. 40 years ago they were a sexy Japanese import with curb appeal, and performance to match.

 

At the height of the 2020 summer Covid shutdown, my attention turned to the Internet and many of the popular on-line auctions sites. Datsun 240Z’s had become a staple on Bring A Trailer, and auctions often featured nut and bolt restorations or original low mile “time capsules”. Six figure sales of a Japanese car that originally sold for around $3500 occurred weekly. Eventually boredom, fond memories, and my own curiosity got the better of me and I decided to add a “Z” to my small car collection. That decision then prompted me to soul search as I contemplated buying a 1970’s era Datsun: Would it be a rotisserie restored early series low mile 240Z that could $100k or more? Perhaps a DIY restored high quality “driver” for $30-50k? Or a 280Z with fuel injection, a more robust build and the optional 5-speed transmission?

 

In the end, after a fair amount of research, chats with local Z owners, and several test drives I settled on the 280Z. I concluded I wanted a car I’d drive, and fuel injection made sense because of lower maintenance costs, and less finicky old school technology. Eventually the ideal candidate came up on BaT. Located in Fresno California, It was a professionally restored 1977 280Z in light metallic blue, with a 5-speed, fuel injection, upgraded suspension brakes and wheels, a new interior, and an impressive stack of receipts from Z Car Garage of San Jose CA. As a bonus, the car had a stroked 3.1 motor built by Hasselgren Engineering of Berkley CA. Dyno’d at 170 RWHP, the straight 6 was producing close to 50 horsepower more than stock and promised performance that would enable it to at least keep up with a modern SUV. I bought the car.

 

Originally intending to have the car shipped 1000 miles from Fresno to Seattle, I thought back to some of the early road trips I made in my 20’s and convinced my 12 yr. old son Andrew that in the middle of the Covid “summer of boredom” we’d have a great time touring Northern California, and the coasts of Oregon and Washington in the new acquisition. The route we decided on would be nearly 1200 miles, and after explaining what a “Datsun” was to Andrew, and some negotiation, we agreed on two things: We’d drive scenic coastal Hwy 101 from Eureka north, and lunches would be at In-N-Out Burger.

 

We flew to Fresno on a Saturday and met the owner at the airport. After a short test drive in which the Datsun performed well, and some chit chat about cars, the weather, traffic, money, and why a beat up Porsche 914 is cooler than a modern Mazda Miata, we were off. We left at 3 in the afternoon on a typical 105 degree Fresno summer day. The owner promised everything in the car worked, and true to his word, the A/C blew cold, which was a big relief. On the freeway, the 3.1 straight six performed well. With noticeably more grunt than a stock 2.8 the car accelerated in a predictable linear manner. No hesitation, no carb flat spot, just smooth running. In fact, I judged its acceleration to be similar to my 207 HP US spec 1985 3.2 Carrera. The 5 speed was tight, the steering crisp, and the overall feel told me we’d have some spirited driving ahead of us.

 

Day 1 took us from Fresno, 300 miles north to Redding CA on I-5, which was uneventful freeway driving. Day 2 was more exciting as we departed Redding early and made our way to CA Hwy 299, a well maintained mostly 2 lane mountain road that snakes 150 miles west through the Coastal range while following the Trinity River to the Pacific Ocean. I’m lucky enough to have driven some spectacular western US “driver” roads in my 60 years, and 299 would rank near the very top for curves, hairpins, fast straights, scenery, and a respectable number of passing lanes. We made it to Eureka and the coast in under 3 hours, and just in time for lunch at In-N-Out Burger, California’s famously good fast food chain. From there we drove north on 101 with a stop at Redwoods National Park and a stroll through The Lady Bird Johnson Grove of Giants. While I’ve always appreciated the amazing machines we humans have managed to build with our big brains and ingenuity, nothing human-made can match the awe you feel standing next to a 2000 year old, 300 foot tall truly enormous tree. From the Redwoods, we proceeded north on 101 along the Southern Oregon coast. Traffic was light, and Oregon State Troopers were few and far between. Andrew and I reveled in the scenery: rugged beaches, breaking waves, jagged near-shore islands, steep cliffs. 101 is a drivers dream! We stopped for the night in the beach town of Florence Oregon, famous for its miles of sand dunes and Honeyman State Park. The next day, after a fisherman’s breakfast and some strong coffee, the plan was to continue north on 101. However, fires closed the road ten miles north of Florence and we were forced to sidetrack east to Eugene Oregon and I-5 for the rest of the trip to Seattle. The last days 300 miles went smoothly, and the Datsun 280Z handled high freeway speeds with minimal effort. At 3000 RPM in 5th, the big 3.1 had us cruising along effortlessly at 80MPH. All in all, a great trip with a great kid in a wonderful car.  Ah, the memories…

 

Enjoying The Ride

 

In March of 2021, Greg contacted us with a nice update on the Z…he had early bumpers installed and it looks great:
