Performance Parts for Nissan, Inifiniti and Datsun Cars

At Z Car Garage we are huge fans of the Nissan 300ZX Twin Turbo, the underdog of 90’s Japanese supercars. Sure the RX7, Supra and NSX get all the attention – but the ’90-’96 Z32 (yes we are biased) represents the best balance of performance, reliability and comfort.  From the intimate feeling of the power leather seats and gauge cluster to the addictive power that evokes a familiar Nissan commercial…

…the Z32 is magical. It is hard to describe how rad these cars are after ZCG has gone through one. Let’s take a look at our customer Patrick’s 1994 Z32 and see of what our 20yrs+ of experience with this chassis can create.

 

Patrick’s Z has been with us for almost a decade, receiving maintenance and upgrades along the way. In 2017 he got into a fender bender and brought it in for repairs. We took this opportunity to replace the control arms, install some loaner Z33 wheels and have William install a full JDM front bumper with sided markers and Powertrix fog light ducts. He also repaired the right front fender and blended existing paint work:

 

Notice the J-spec tail lights, one of our favorite aesthetic mods and it looks so good on the black Z32s.


 

We installed them and the center panel replacing the factory units:

 

William really knocked it out of the park with the paint work.

 

Stoptech Big-Brakes

 

As every Z32 owner knows, the stock brakes just aren’t up to the task. More power exacerbates the issue and you know how we feel at ZCG:  It’s Stoptech Or Don’t Stop At All.  Patrick’s car had larger than factory wheels allowing us to install 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 Stoptechs look nice too! One of Patrick’s wheels was damaged in the accident we replaced them with a set of SSR GTx-01 18×8.5F and 18.×9.5F. Finished in flat black with center caps running Bridgestone 007a 245/275 tires and Volk Racing lugnuts:

Details

 

Patrick’s interior needed attention with a new passenger side window motor. We also installed new rack bushings and detailed the entire car.

 

Power Upgrades

 

With the front end off it was the perfect time for power upgrades: JWT clutch/flywheel, Ashspec Massive intercoolers,  Selin translator dual MAF and BDE Performance motor mounts to allow for Ashspec 2.5″ inlet piping.

ZCG 51714 020 ZCG 51714 032
 

Exhaust upgrades included a full SpecialtyZ 2.5″ exhaust with single outlet option:

 

On the dyno Rob tuned the Z making 349hp/375tq to the wheels on 91 octane:

Felix’s 300zx Twin Turbo

We might be biased but we feel the Z32 is the best Japanese sports car of the 90’s. Keeping them on the road is our passion and even in 2019 there are still some real gems out there. Felix C brought his 1996 300zx Twin Turbo in to ZCG under dire circumstances and here is how we met him.

 

While we were at the Spring Classic event at Laguna Seca a customer was trying to buy a ’96 Z32TT from SoCal. Rob informed this customer to hold off buying the car until inspected by our friends at SpecialtyZ. When we got back to the shop at night to unload our cars from the race weekend…that ’96 Z32TT was sitting in front of Z Car Garage!

 

The following morning a gentlemen named Felix called to say he had purchased this car in SoCal and on the way home it broke down. With 96k miles the odometer, this Z32 from came to ZCG with a busted fan clutch. When the fan clutch failed it made a mess of the radiator and front end. The first visit for Felix was a full inspection with a plan to remedy all problems to get him back on the road. We installed a new Koyo race radiator, our one-step colder plugs and performed full timing belt services:

ZCG CAM4 71314 048 
 

 

Power Upgrades

Felix returned after feeling the need for more power and we also knocked out a few more items from the initial inspection. Power upgrades included a SpecialtyZ 2.5″ exhaust with resonated x-pipe and dual tips, 740cc injectors, Ashspec massive intercoolers and Greddy boost controller:

ZCG 82514 CAM 4 009
 

On this visit we also got the A/C working with a new condenser and drier. A new fuel pump and all fuel hoses on top of the plenum were replaced:

 

The engine bay was cleaned up, including oil cooler lines:

 

More power upgrades: Selin translator dual MAF and BDE Performance motor mounts to allow for ASH-SPEC inlet piping. Massive IC from Ash shown below:

ZCG 51714 019
ZCG 51714 020 ZCG 51714 032
 

Dyno Tuning

We dyno tuned Felix’s Z with each power modification. It came in with a failed knock sensor, causing the low baseline power levels of 220hp/223tq. The knock sensor was fixed:

 

Great gains with the SZ exhaust system for 313hp/334tq to the wheels:

Ash-SPEC intercoolers:

 

Rob’s final tuning really woke the Z up, yielding 357hp/351tq to the wheels on 91 octane, dyno video below:

 

 

Interior

Felix wanted us to sort out the interior. During this visit we installed some weatherstrip, fixed an ABS sensor code and eliminated a few door panel rattles.

   
 
 

Felix added LED lighting:

 

The highlight of the cabin: we had the seats re-finished to OEM spec!

 

Big-Brakes and Chassis

 

As every Z32 owner knows, the stock brakes just aren’t up to the task. More power exacerbates the issue and you know how we feel at ZCG:  It’s Stoptech Or Don’t Stop At All.  Felix’s car had larger than factory wheels allowing us to install 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 Stoptechs look nice too!

 

Stillen sway bars front and rear and we replaced all of the power steering hoses:

 

The Z had outgrown its suspension and it was 40th Felix’s birthday. We delivered icing on the cake with KW V3 coil-over suspension:

 

Installed front and rear:

 

More birthday goodness: super sexy SSR GTX-01 wheels in 18×9.5 with Bridgestone S-04 tires:

 

Wheels/tires being mounted:

 

Notice the J-spec tail lights, one of our favorite aesthetic mods and it looks so good on the black Z32s. Of note is the license plate “AUDREYH”…Felix wanted to pay tribute to his Mom’s favorite actress, Audrey Hepburn:

“aka Fairlady Z since the designer named it after the classic movie My Fairlady. The actress in the movie is the beautiful Audrey Hepburn. Hence I chose AUDREYH.  I figured a classic lady should have a classic name with relevance.”

 

The 300 is now well-sorted and Felix is loving it. He did his first track day at Sears Point (Sonoma Raceway) and had a blast hustling the Z:

 

“Rob and the team is a high energy team that takes their work seriously while having fun.  I’m happy what they have done to the car and also ecstatic that they share equal appreciation of the Z32”

UPDATE:

Felix is Enjoying The Ride as I write this blog post! He sent me these awesome pictures minutes ago with another Japanese sports car we admire…the FD RX-7:

Z Masterpiece: Jas’ 300zx Twin Turbo

Filed under: Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 1:52 am on November 19, 2014

CAM 2 103114 202
 

Nissan’s Z32 Twin Turbo is a sportscar that has truly stood the test of time. Its curvaceous lines have aged gracefully and the venerable VG30DETT powerplant is still capable of producing impressive numbers today. We love them and specialize in keeping these beauties on the road and in the hands of proud owners like Jas D. He picked up this 1990 300zx Twin Turbo last summer and visited Z Car Garage for a thorough inspection.

ZCG CAM4 71314 033ZCG CAM4 71314 041
 

Though bone-stock with an amazing 44k miles on the clock it needed some attention. We went through the hydraulics and performed full 60k-mile services.

Jas wanted to improve power and handling and we happily obliged with a comprehensive list of upgrades this year.  Starting with the drivetrain, the original transmission was replaced with a brand new(!) unit from Nissan:

ZCG CAM4 71314 100ZCG CAM4 71314 104ZCG CAM4 71314 102
 

The clutch had seen better days so we replaced it with a JWT unit including their heavy duty aluminum flywheel:

ZCG CAM4 71314 061ZCG CAM4 71314 099ZCG CAM4 71314 098
 

A JWT ecu w/boost jets manages uprated NISMO 740cc injectors and the Selin dual MAF. Improved breathing comes from Ash-SPEC inlet piping and dual JWT pop chargers:

On the exhaust side, restrictive original downpipes were replaced with these beautiful Specialty Z 3″ downpipes. Note the divorced wastegate piping:

Following the new downpipes are more parts from SPZ including 3″ mid-pipes and a cat-back exhaust system to replace the OEM setup:

With all of the speed parts installed next we tackled chassis improvements. Lots of goodies here so let’s begin with brakes followed by suspension:

ZCG 82514 CAM 4 061

We love Stoptech’s products and use them on our own vehicles.  Z32s are relatively heavy and with higher hp the stock caliper/rotors can be taxed quite easily. Jas took it up a notch and ordered a Stoptech 4-wheel Big-Brake Kit for his beloved Z.  Shown above is the ST40 caliper (front) squeezing 332 mm rotors and at the rear are ST22s on 328mm rotors.

The installation:

Yes, they are pretty but also very functional! Speaking of aesthetics(that are functional, too), the new calipers are nicely framed between the spokes of these sweet VOLK TE37SL wheels.  We like your taste, Jas.   The lightweight TE’s were wrapped in Bridgestone S-o4 tires:

ZCG 82514 CAM 4 088ZCG 82514 CAM 4 087ZCG 82514 CAM 4 095
 

Several suspension upgrades improve handling and replace old/deteriorated parts. Stance coil-overs were installed while Stillen sway bars front and rear help reduce body roll:

OEM vs Stillen sway bar mount/bushing and end-link details:

More suspension parts include SPL T/C rods,   Z1 upper control arms and new steering rack bushings:

ZCG 82514 CAM 4 016ZCG 82514 CAM 4 022ZCG 82514 CAM 4 064
 

The Z looks fantastic with the new footwork:

CAM 2 103114 200 CAM 2 103114 203
 

Jas came back to Z Car Garage in Septemeber for a few more upgrades. We installed 4.08 Leader gears, Ash-SPEC Massive SMICs, 2.5 IC tubing, and  SPZ Hi-5 upgraded clutch. The BDE low-profile Z32 motor mounts are a smart alternative to OEM that allows more clearance larger for intakes:

After the addition of larger intercoolers and piping we re-tuned Jas’ Z picking up power throughout the rev range for a total of 369hp/387tq to the wheels:

Jas D Z32TT Massive Intercoolers and tune
 

We think Jas’ 300zx Twin Turbo is the perfect addition to his stable. It is now a balanced sportscar with just the right personal touches. Long Live the Z32!

More Upgrades For Ken’s Z32 TT

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 12:12 am on April 19, 2013


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!
