Here at Z Car Garage we LOVE to drive our cars on the racetrack. Open “Track Day” or High Performance Driving Events (HPDEs) are excellent venues to familiarize yourself with a car and its limits while having fun in a safe, controlled environment.  Two of our customers recently shared their first track-day experiences with us and they had a blast!

 

We supercharged Robert C’s G35 last year and he decided it was time to do his first track event at Laguna Seca Raceway. He’s added these gorgeous RAYS Gram Lights 57Xtreme wheels since his last visit:

 

“Rob!
Just want to tell you I had a incredible day at Laguna. David Ray is a great guy and awesome teacher. We spent the first three session working on line, smoothness and consistency with both until I had all 11 corners worked out. The 4th session we put it all together as he pushed me and it was phenomenal! When I IR’d the front rotors after the session I was over 500 degrees and they were smoking. Happy to report brakes are still great and no warpage on the rotors. Ironically David mentioned doing an ST40 upgrade which we already quoted earlier so know that is still on the radar for my next track day. Nice to have someone just back up a buying decision without asking. I did graduate to Solo and was told to register for Group B next time so pretty pleased about that. On the upside I have marked “Drive my car at Leguna and hit the corkscrew” off my bucket list. On the even bigger upside I’ve added “1) Go drive Laguna more. 2) Drive Infineon. 3) Drive Thunderhill and 4)Drive Buttonwillow.” to the list.

David had praise for the current work done on the car and I have to agree. The work you and team have done since October last year has made this car even more enjoyable and something to proudly run on a track. The car had zero issues and feels no worse from the day.”

In October we added some bolt-ons and tuned Garth J’s 350z preparing him for a day at Thunderhill Raceway:

“Hi Rob,

Thunderhill track day was awesome a few weeks back. Car felt great. The Bridgestone S04’s were a major upgrade. Thanks for preparing the car for a great experience. I’m thinking about auto-crossing next season.Will be needing some routine maintenance in the new year. Can we schedule something mid January? Happy Holidays.”

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:

 

Brian’s stock calipers and the Brembo calipers front and rear. Two-piece rotors are from Giro Disc:

 

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!

We love to install bolt-on parts that add power to your Z/G car. At Z Car Garage UPREV tuning can maximize power gains from individual modifications like intake/exhaust upgrades. Here are two examples of how we consistently achieve better performance through tuning, with mods or even without!

Mike F is a long time friend of ZCG and owner of a very cool 700hp Fox-body Mustang. His daily driver and family-unit vehicle is this G35 S sedan and Mikey want to give it a little more oomph.

 

We installed Berk high-flow cats followed by an UPREV tune.  The automatic-equipped G gained 18hp/11tq for a grand total of 277hp/249tq to the wheels. Another significant benefit of tuning: the VQ can now rev all the way to it’s sweet 7500rpm redline!

 

Scott A’s Nismo 370z is a great example of UPREV tuning improving power/delivery without any bolt-on mods.

 

With tuning the Z is now past that magic 300whp mark at 314hp/262tq to the wheels. Great all-around gains in torque with significant mid-to-high range gains in horsepower…just from the UPREV!
