To appreciate the 1991 Aztec Red 300ZX Twin Turbo pictured above we must tell you a story of love, heartbreak, persistance and ultimately satisfaction. Z Car Garage client Jas D has been with us since 2014 when we helped build his 1990 Nissan 300ZX Twin Turbo. This Super White, 44k original-mile example was treated with all the ZCG touches that make a Z32TT go from wonderful to extraordinary. We dubbed it the “Z Masterpiece” (see more here) as it embodied the total package: Power. Handling. Braking. Aesthetics:

 

Jas totally Enjoyed The Ride in this Z, adding 28k thrilling miles with ZCG maintaining it over the years:

“My brother and I have been ZCG customers for almost a decade. I met Rob when I called about getting a PPI on what became Z Masterpiece. At the time, a Super White manual came up on AutoTrader (I LOVE Super White-OMG). It was a low-mile, one-owner, meticulously-maintained time-capsule. Rob actually said WOW after the PPI, and we worked with ZCG over a couple years on a few iterations until we got Z Masterpiece. That car was perfect!  My dream Z; I loved driving that car EVERYWHERE! It is probably my favorite car of all time!”

  

Unfortunately, in 2016 the Z was stolen.

“On October 29, 2016, Z Masterpiece was stolen. We cried, we laughed, we got angry, we sulked for a couple months, forgot about it, and then my dad found the car driving into SF on January 25, 2017. The car had clearly been driven like it was stolen. But, believe it or not, all the expensive components were still on there. We sent it to Rob right away, and he helped us turn Z Masterpiece into the Red Devil Z (which I purchased on April 20, 2017 with 66,XXX miles).”

From Z Masterpiece to Red Devil

 

Persistance paid off, and Jas found a really clean Aztec Red ’91 Z32TT with only 66k miles. All of the upgrades from the Super White, Z Masterpiece were transferred over:

“Rob pulled the motor from the Super White, re-did all the seals/gaskets, and then put the driveline back together into the red Z32TT.  Coincidentally, both cars and engines had 66,XXX miles when this was done in summer 2017.”

 

 

Let’s take a look at the modifications that turn the already stellar Nissan 300ZX Twin Turbo into a superb, balanced sports car.

Engine

 

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:

 

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:

   

Rob recently dyno-tuned the red Z, making 353hp/353tq to the wheels on 91 octane:

 

Stoptech Big-Brakes

 

With all of the speed parts installed next we tackled chassis improvements. 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, finished in bronze and sized 18×9.5/10.5 in high-pad offset with center caps.  We like your taste, Jas.  The lightweight TE’s were wrapped in Yokohama tires:

 

Suspension

The suspension was gone through completely with all new parts. KW V3s are our favorite coil-over setup, replacing the Stance coil-overs that the Super White Z had. Stillen sway bars are also shown:

 

Stock vs KW V3s installed front:

  

Rear:

  

Every little nook and cranny of the suspension was handled. New SPL tension rods, upper front control arms, new rear wheel bearings and HICAS removal/eliminator:

  

T/C rods, Stillen sway bar, we also replaced the rack bushings:

 
The Z looks great!

  

The interior is in great condition as well:

  

Jas and his brother love the Z. Thanks for letting us be a part of your journey!

“The Red Devil Z is vicious and so fun to drive. It is the quintessential 1990s Japanese sports car  – red – gold wheels – TTs – exhaust.  It goes fast. It stops fast. It turns fast. Z32TTs are the BEST! We love and respect Rob and the team at ZCG. Rob is a total big brother. He and the team have been with us through the passion and pain.”

**This Red Z32TT is for sale on Bring a Trailer!**

 

The quest for the perfect Z is almost complete as Jas just found one of the cleanest Super White z32s on Earth. That means the red car is for sale! Jas is listing it on Bring a Trailer. We will update this post and social media when the auction goes live so you don’t miss out! For now, enjoy the extensive photo gallery below, and LONG LIVE THE Z!

“My first dream car was 350Z. I learned about Z cars in my college days and I recall a cool kid driving one while I was waiting at a bus stop in the cold rain. We had an opportunity to buy a new car and I was very fortunate that it could be a Z. After purchasing the 370Z, 6 months later went to ZCG and the journey began. No offense to stock Zs but these are meant to be modified 🙂 My wife and I both love our Z and I thank her for  supporting my hobby 🙂 “

 

Bolt-on Beginnings

 

With only a few months of owner-hip of his new 370s Sport Touring Henry visited us for upgrades. The latest Z34s had ECU changes and no software support at the time. Henry knew he wanted to go forced-induction so in the interim we started bolt-on upgrades. In April of 2019 the chassis was treated to full KWV3 coil-over suspension with SPC F/R control arms and Hotchkis sway bars:

 

A few installation pictures, followed by a full alignment:

 

A cat-back exhaust system from Armytrix with Valvetronic sound adjustment:

 

Henry requested a new steering wheel install:

 

Stock (with a cover) removed and new carbon fiber + alcantara-trimmed wheel installed:

 

Time For Boost

 

With 12k miles on the odometer Henry was ready for boost. We ordered the Stillen supercharger kit (black), CARB-legal for piece of mind. Supporting parts included a Concept Z 25-row oil cooler (thermostatically controlled), Stillen transmission cooler and fueling upgrades. Here a few pictures of the installation:

 

Fueling upgrades include a CJ Motorsports stage 1 fuel return system and billet fuel pump hat, 1300cc Injector Dynamics injectors, Hellcat Wallbro fuel pump, SpecialtyZ flex fuel kit:

   

The SpecialtyZ flex-fuel kit comes with a Zeitronix gauge that we mounted in pace of the OEM clock:

 

Cooling upgrades include Soho Motorsports air-to-air intercooler, Concept Z 25-row oil cooler (thermostatically controlled) and Stillen transmission cooler. Also shown is the Fast Intentions crash bar with tow-hook:

 

Oil and transmission coolers:

 

We installed a Fast Intentions billet flex-plate, much stronger than the OEM unit:

 

Finally, we changed the exhaust from Armytrix to an ARK Grip setup paired with ART Pipes from Motordyne:

 

Henry loves the current exhaust setup:

“I’ve gone through Nismo OEM, Armytrix, and eventually settled with Rob and a friend of mine’s suggestion for the forced induction route: Ark grip catback system + Motordyne art pipes = the deep growl without screaming. Sort of the centered idea of the goals of my Z project – subtle power without drawing attention.”

 

Dyno Tuning

 

We wanted the most efficent blower wheel to run ethanol so the V3 SI blower wheel was installed. Ecutek software  was used for tuning, MAP-based with omni sensor.

 

Shown below are dyno graphs from when Henry was NA to 91 octane and E75 tunes on the Vortech. NA, the Z made 316hp/252tq and a 91 octane tune supercharged yielded 501hp/370tq at the wheels:

 

Rob then tuned the Z on E75 for 573hp/426tq at the wheels:

  

Enjoy the dyno tuning video!

 

We are very happy with the results and even more stoked to hear Henry’s feedback on the supercharger and tuning performance:

“The supercharger is very daily usable and power whenever I want!  The sc mods put together and tuned by Rob for a 7at Z is able to reach 570+ whp and 430 wtrq and still feel smooth and dramatic at the same time is absolutely beyond my expectation (I followed every ZCG 370Z blog posts and it’s a honor to be one of the highest power 370Z from ZCG, hats off to Rob) And did I mention daily-driveable? Good surprise for me. In addition, Rob has been really patient and knowledgeable for all my questions and requests and late night text regarding my Z. It really felt like we built the car together but it’s all his magic touches! I really appreciate the journey! More to come”

Wheels Make the Car

 

We have said it before: wheels make or break a car.  After long discussions with Henry we decided on the Ray’s TE37 Ultra Track Edition II. Finished in Blast Black and sized 19×9.5/10.5 these wheels look perfect on the Z34.

 

We love the little details Ray’s applied:

 

Enjoy The Boost!

Henry has been Enjoying The Ride in his supercharged 370Z.

“I love my Z and ZCG! Long live the Z! ZCG has been the place to go if you love Z cars, new or classic. Rob and the shop/crew exude passion for Z cars and you immediately know they will take care of your Z and your Z will be among its family. Rob has been great through the journey and worked with “our” Z. I am sure there is more to come for my Z with ZCG!”

  

You can follow Henry here on Instagram. What’s next for his Z? He’s playing with idea of a body kit but trying to maintain that subtle-aesthetic approach in his build. Stay tuned! Thank you Henry for letting us build your Z. It’s very cool for us as a shop trying to make 50-old cars keep with cars like this. We enjoy playing with the new stuff just as much as the classics. LONG LIVE THE Z! More pictures in the gallery below:

On Saturday I joined six other cars for a morning cruise through the Santa Cruz Mountains. The two S30 Z cars with us were running our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!

Glenn’s 1972 Nissan Fairlady 240z-L

 

Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:

“The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me and the ZCG brakes deliver. WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car”

This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few pictures of the Big-Brakes being installed on Glenn’s Z:

 

Glenn was having fun on the twistys on our cruise (see video below). Learn more about his Z in this Petrolicious video.

 

James’ 1972 Datsun 240z

 

James is running our ZCG BBK (1st gen, 328mm) and  Z Car Garage CV Axles in his turbocharged L-Series beast:

 

 

You can learn more about this 560whp Z on Speedhunters and see it in action on Hoonigan Autofocus. James also had a blast on our Saturday cruise:

 

Saturday Cruising

 

We started our drive in Downtown Saratoga and made it to the coast via Bear Creek and Bonny Doon Rd. Here is a short video:

 

We were happy to enjoy the company of cool cars and cool folks, also joining us:

Dustin’s 510

 

We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. The side exit exhaust is loud!

 

Tony’s Mazda RX-2

 

Tony has had this RX-2 for many years. In addition to the full restoration it now has a full (S5) 13B drivetrain with a Ford 9″ rear end! It is mint. I haven’t seen Tony in many years so it was a joy to have him along:

Lloyd’s AE86

 

Lloyd has a very cool collection of cars and this AE86 is the latest. Although it sports an F20C drivetrain (Lloyd promised me it’s not the same car as this one), it has numerous upgrades for a better drive. Gotta love TE37s:

 

Geoff’s BMW 2002

 

Geoff’s no stranger to our Bay Area cruises and also owns a Lotus 7. He was the only German this time with his BMW 2002 on rare Campagnolo wheels:

 

I drove my SR-powered ‘67.5 Datsun Roadster and it was a great way to spend the morning.

 

Yes, that’s a Ferrari 250 GT Lusso flying by on HWY 1!

Matt O is the lucky owner of this 1991 Skyline GTR finished in (TH1) Midnight Blue Pearl.  When we first met he wanted to bring the car in to ZCG for a quick checkup. We looked over it, ran a compression check and also made a plan for his next visit.

 

Matt acquired this California-legal R32 from our friend Sean and his team at Toprank International Vehicle Importers. It goes without saying, if you are in the market for a vintage Skyline (or any JDM car) IVI is the place to go.

   

In March of last year Matt came in for a Haltech Platinum Pro. We have installed many of these and it’s a great foundation for adding power to the R32.

 

We performed all the prep work and ran a the boost sensor to install the Haltech.  Whenever we take on these cars we always run a smoke test to ensure there are no intake leaks present.

  

On the dyno, results for the baseline run (left) followed by Haltech on 91 octane. Despite having a healthy engine/turbos the power levels were fairly low on this car. The culprit: weak actuators not allowing the car to hold boost. Matt will visit us again for new turbos and acuators so it will get a big jump in power. We are big fans of Haltech and now he’s prepared with the right engine management system.

  

Next, we installed a few suspension upgrades supplied by Matt followed by a full alignment:

 

Cusco T/C rods, rack bushings and toe-link/rear control arm setup:

    

T/C rods

   

The R32 had a set of SSR SP1 wheels and Matt wanted to change the look with a fresh set of new wheels: 18″ Volk TE37 finished in bronze.

  

We mounted/balanced his RE071R tires and the Skyline looks sweet:

Matt has been Enjoying The Ride in the R32. Here he is at Laguna Seca:

  

We even caught Matt out on a local drive! Here he is parked next to Naveed’s R32 (story coming soon):

 

Thanks for bringing your Skyline to us Matt. We look forward to more boost! Catch more of Matt’s Th1 R32 on his Instagram

 

We are excited to sponsor and be a part of the 2018 Japanese Classic Car Show this Saturday 9/15 in Long Beach.  Stop by the Z Car Garage booth to see our Big-Brake kit for small wheels, CV Axles and pick up some free swag.

 

   On display in the ZCG booth is one of our latest builds, Randy Jaffe’s 1970 Series 1 240z:

  

 

We are also very proud of ZCG customer James S’ 1972 240z. He will be driving his turbocharged L-series down to JCCS and displaying it with fellow owners.

   

 

The show takes place from 9:00 am to 3:00 pm in Marina Green Park, and it is the highlight of all J-Tin shows!  Catch a glimpse of what JCCS is all about in our report Last year’s show. Z you there!
