Three for Thursday! Here are 3 owners that visited Z Car Garage for upgrades so they could Enjoy The Ride. Thomas C was experiencing brake fade/overheating with the Akebono caliper setup on his G37 Sedan. We installed a Stoptech Sport Kit with our favorite SS309 pads:

 

Slotted rotors also help shed heat, before/after shown below:

 

We also UPREV tuned the G now making 291hp/247tq to the wheels:

 

Rich M wanted firmer shifts from his automatic-equipped G37 Coupe. We installed a TransGo shift kit followed by UPREV tuning:

 

TransGO kit:

 

The dyno plot reveals the benefits of UPREV tuning and the TransGo kit. Firmer shifts are evident by the absence of the “loop” (blue curves) seen with OEM automatic-equipped Z/Gs.  Huge peak gains of 20hp/18tq to the wheels and increased area under the curve everywhere means this is power you can feel!

 

Garth J brought his 2003 350z to us for Stoptech lines, 5/16″ plenum spacer and MREV2 lower intake, and new Bridgestone PP S-04 tires:

 

With the intake mods and UPREV tuning Garth’s Z picked up 7hp/5tq to the wheels. More importantly are the mid-range and top-end gains:

How can we help you enjoy your Z or G?

 

Just over a year ago Brian K visited Z Car Garage for several bolt-on parts on his 2006 350z including a JWT Pop charger, Motordyne 5/16″ plenum spacer, Bassani cat-back exhaust system and UPREV tuning.

 

 

As we all know it is hard to resist adding upgrades to your sportscar and after enjoying the Z with its new mods Brian came back to ZCG for full 60k services, Hotchkis sway bars and Brembo brakes.  The OEM Brembo calipers were sourced from Gabe V’s G35 coupe. Gabe upgraded to a Stoptech Trophy setup, full report on his build soon:

Looking good through the ’06 wheels!

 

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.

 

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:

 

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

 

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:

 

OEM vs SPZ:

 

 

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:

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:

 

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:

 

The Z looks fantastic with the new footwork:

 

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:

 

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!

Lots of pictures in the gallery, enjoy!

I love driving my Datsun Roadster every weekend but last Saturday I had the opportunity to drive Rob Fuller’s 1971 Datsun 510 for my birthday.  This is Rob’s first 510 from his youthful days in Georgia (see vanity plate). Without giving too many details, he restored the car and performed an S13 SR20DET drivetrain swap in 2002.  We will give this Dime a proper feature on the blog soon, but for now, let’s drive!

 

I called up a few of my roadster friends to do a quick blast up Skyline to Alice’s restaurant. Both Mike (silver) and Raul’s (white) roadsters are 1967.5 year cars with SPL and SRL drivetrains, respectively. With HWY 9 construction finished the twisty roads we once enjoyed were now even smoother.

 

We headed South on 84,  looped back up to Skyline via Old La Honda Rd and eventually took a break at the vista point off 9 towards Big Basin.  Driving the Go Green 510 was buckets of fun. Seating/steering wheel position, suspension and visibility all make for a totally different experience coming from a roadster owner. I was impressed how well the car has held up over a decade after it was reborn.

 

After our fun run my brother and I did some lead-follow videos with my roadster and the 510. Two SR-powered vintage Datsuns Enjoying The Ride! Turn those speakers up:

 

Cruising around town and experiencing the rush of 400hp being transferred through 205mm-width rear tires was absolutely addicting.  Thank you Rob for making my birthday especially enjoyable!

 

Matt found Z Car Garage by referral from a local car wash. He had installed a few bolt-ons and needed a tune so we UPREV’d his 370z. Baseline numbers were 294hp/238tq and after tuning 309hp/253tq:

 

The dyno shows significant gains in hp and tq throughout the entire rev range. We are big fans of UPREV tuning and it consistently works well when optimizing individual mods. We will have more examples this week on both NA and FI cars so stay tuned!
