Jay H has been our customer since the beginning. He has a Datsun 240z, Mazda (FD) RX-7 and this 1990 Aztec Red 300ZX Twin Turbo that he’s owned for many years.  Living in a rural, wooded area the Z’s wiring got chewed on by rodents. We fixed the wiring and got the car running again but more issues surfaced. Jay loves this Z so much and it had 122k miles so he decided it was time give it some serious attention.

 

Z Car Garage was happy to oblige as we think the Z32 is one of the best Japanese sports car of the 90’s.

Engine Bay and Drivetrain

 

The engine bay was in need of major cleaning and restoration. First, we performed a compression/leakdown test and the Z passed. With the engine out now we could focus on cleanup:

 

We installed a new engine room wiring harness. Every coolant hose, bypass hose, vacuum hose was replaced. A new underhood insulator with clips replaced the torn oem piece.

 

All p/s hoses were replaced and we modified the p/s steering pump to reduce clutter and eliminate the HICAS completely:

 

The engine was treated to full reseal and timing belt services, more pictures of the engine build in the gallery!

 

With a clean bill of health we installed several performance upgrades including JWT sport 500 turbos, BDE billet half moons/motor mounts, Ashpsec inlet piping, Selin dual-MAF with HR  low-profiles filters/two Z32 MAFs and Nismo 740cc injectors:

 

No turbo upgrade is complete without the Mike Smith turbo manifolds with EGR ( to pass emissions). Unfortunately we will install the last set of these on Felix C’s 300, and that’s it!

 

BDE motor mounts:

 

Nismo 740cc injectors:

 

Ashspec inlet piping:

  

Selin dual-MAF with HR low-profile filters:

 

Before the engine went back in we installed a new JWT HD clutch and aluminum flywheel:

 

The drivetrain was re-installed with numerous items like a new fan and engine cover:

  

Exhaust upgrades included a full SpecialtyZ 3″ exhaust with 3″midpipes:

 

Finally, a GReddy Profec boost controller was installed in the super tidy interior:

 

Rob dyno tuned the Z, making 384hp/348tq to the wheels:

 

Exterior

 

With the engine bay and drivetrain sorted we turned to the body and and exterior trim. Jay wanted to do a full repaint on the car so we had it had it towed engine-out to our man William. Some before shots showing the faded paint and cracked/peeling tail light panel:

 

At William’s the body got some choice parts to make it look like 1990 again: Wings West Pre-’94 rear wing, JDM front fascia (with shaved license plate mount) and Jspec tail lights. With the freshly painted Z back at the shop we tackled re-assembly of new cowl panels, mouldings and various trim. All of these parts really make this Z pop:

 

Extensive moulding/trim replacement: T-top trim before/after shown below

 

Door and window trim:

   

Jspec rear and front looking sharp!

 

Icing on the cake are Jay’s super cool set of old WORK Equip 05 wheels.  We re-finished and polished/painted them running Bridgestone S-04 tires.

 

Wheels make the car and this Z looks incredible standing still and on the road:

Suspension

The chassis received a few upgrades including Stillen sways and SPL titanium HICAS delete We also replaced ABS module the clutch and brake master cylinders

 

One Z Car…Coming Up!

 

Jay didn’t have a car for the duration of the revival and he was on foot running errands near his home.  We handled all of the DMV fees foe him and Rob and Alvin delivered the Z to Jay at his residence.

 

It was a great experience to pull up in the 510 and Z to present it to Jay, he was all smiles:

  

Thank you Jay for bringing your 300zx to Z Car Garage. We admire your love for the Z and passion to keep it on the road in top form! Z32s ROCK! Enjoy the extensive photo gallery below:

LONG LIVE THE Z!

How do you start the New Year off on the right foot? Drive your Nissan/Datsun! Today I joined Rob and Lou for a nice drive through the South Bay foothills. Rob and shop dog Kane drove the 820hp ZCG 300zx Twin Turbo, Lou drove his 470hp R32 Skyline GT-R and I drove the 460hp Datsun 510.

 

Our route included stops at both Uvas and Calero Reservoirs with a nice mix of long sweeping curves and windy, single lane farmland roads with picturesque bridge crossings:

 

 

At Uvas Reservoir we met a nice gentelman and his tubbed ’66 Chevelle:

 

Before departing we made our final stop to admire just how “right” Lou’s R32 looks with the new VOLK TE37SL wheels. Amazing car!

 

 

We hope you can enjoy driving your car in 2015. Follow the blog and Facebook for upcoming fun runs!

Our last report on Ken’s 300zx included suspension and extensive power upgrades. Ken came back to ZCG for tuning and installation of:

-Ash-Spec inlet pipes
-BDE motor mounts
-Quaife LSD and 4.10 Leader Gears

Here are the new Ash-spec inlet pipes compared to the old:

You can thank your lucky Z stars for BDE low-profile Z32 motor mounts, a smart alternative to OEM that allows more clearance larger for intakes:

A set of 4.10 Leader gears along with a Quaife LSD were installed:

 Ken tells us that he feels a noticeable increase in acceleration and traction from the rear end mods. With Rob’s tuning the Z now puts down 418hp/396tq to the wheels!  Peak numbers may be nice but check out the overall gains…a solid 40-50 hp/tq improvement from 3500rpm to 6500rpm:

Enjoy the Ride Ken!

In 1990 Nissan changed the Japanese sportscar world by introducing the Nissan 300ZX Twin Turbo. James L from San Francisco was ready to find out what all the excitement was about and purchased this gorgeous Red Zed. That’s right, he is the original owner!
Fast forward to fall of 2010…James kept this Z in amazing shape driving his machine only when the weather was right. No rain for this Z. It had been 20 years and there were 60k miles on the clock. He was reading about the new and improved Corvette and how this American sportscar was the end all be all. James even went to the extreme of renting one for a few days to see if he liked it. After 20 years could he really turn his back on the Red Zed?
No way!

After doing his homework on some Z32TT modifications, James found Z Car Garage. We met and he told me he had this Z since new and was finally ready to take it to the next level.
We performed a full inspection from top to bottom and found James’ Z suffering from common issues at his mileage. The clutch was slipping badly, as evidenced by the baseline dyno:

The transmission was removed and a JWT HD clutch with lightweight flywheel were installed:

The factory pre-catted downpipes are restrictive and large power gains can be found here so 3″ fully divorced downpipes from SpecialtyZ along with a full stainless exhaust system were installed.
Fully divorced downpipes:


The exhaust system consists of a 3″ mid-pipe with resonators ending with 2.5″ dual tip mufflers. Note the rusted factory resonators and restrictive piping:



The final before/after and how the Zed will look as it blows by those ‘Vettes 🙂

A common performance upgrade on the Z32TT is the air intake. Dual JWT POP chargers help in the breathing department, and look pretty cool too. Look how clean that factory airbox is!


The factory ECU was sent to JWT to get fuel/ignition re-mapping(Stage3) and boost raised from 7psi to 13.5psi. The revamped ECU, new exhaust/downpipes, and intake help put down an impressive 356hp/369tq to the wheels!
Whoa is just as important as go, so a full Stoptech sport/street brake package was installed. This inlcudes stainless steel braided lines, new rotors, pads and MOTUL brake fluid. The clutch hydraulics were also freshened:

Corvette Summer is on hold…its cold outside and as well all know turbos love the cold.

Enjoy the ride James!!!
