Back on the Track: Robert’s Vortech G35

Robert C had such a good time driving his G35 at Laguna Seca that he came back to ZCG for more track preparation!  Since adding almost 200whp with a Vortech supercharger, it would prudent to upgrade the braking system. We are big fans of Stoptech’s brake kits and lucky for Robert one of our customers was willing to part with a lightly used ST60 (front) and ST45 (rear) caliper setup:

 ZCG 1 21015 025
ZCG 1 21015 026

Stainless steel lines and larger cross-drilled/vented rotors (355mm) were installed at all four corners:

The obvious difference in rotor/caliper size results in increased heat capacity and pedal feel. More importantly these big-brakes will ensure repeated, fade-free braking while running on the track!

They do look stunning behind the spokes as well:

We also installed a JWT flywheel and clutch:

ZCG 1 21015 037ZCG 1 21015 038ZCG 1 21015 039

With fresh brakes and clutch Robert attended his 2nd track day, this time at Sonoma Raceway:


“Hey Rob,
Track day at Sonoma was incredible. Car was great and ran perfectly the whole time. She just loved sweeping up the hill to turn one and running through the esses. Powering and tracking out of the carousel then running her all the way from there to the brake zone for turn 11 is just…all I can think of to describe it is the word “happy”.
I was only doing 2:23 as a best lap but seeing as this is my second track day ever and my first time driving Sonoma, I’ll take it!”


Great work, Robert. We are happy that you can enjoy track days with confidence. The G looks superb out there!

Nissan legend Yutaka Katayama, aka “Mr. K,” dies at 105

Nissan Legend Yutaka Katayama

It is a sad day for Nissan and Datsun owners as we learn about the passing of Yutaka Katayama, father of the Z car. The news has spread throughout the media from NissanUSA to Wall Street.


As many of you know,  Mr. K is the father of the Z Car and was honored for his innovative design of the early Z Car that set the bar for others. He helped Nissan to become the best selling import brand in 1975.

He also positioned Nissan to become the 1st automaker to sell Americans on compact pickup trucks and “King Cabs”.   Here is Mr. K with the actor (Dale Ishimoto) that portrayed himself in Nissan’s famous “Dogs Love Trucks” ads:


Retired from Nissan since 1977, Mr. K still had a drive for styling. He played a major role in refining the Nissan Z concept car that was unveiled at the North American Auto Show in January 1999. On October 13, 1998 Mr. K was inducted into the Automobile Hall of Fame museum in Dearborn, Michigan.

We have fond memories of Mr. K at our local and national Z-car shows. It always amazed us how enthusiastic and full of verve this man was to come stateside and participate in our love for these cars. Here is Mr. K at a Z show in the Bay Area, circa 2002. Like many Datsun owners I too was humbled when he signed memorabilia/car parts and shook hands. Mr. K was driving a Z well after he turned 100, noting that his driver’s license was good through his 103rd birthday. Amazing individual.

Having excellent communication skills even in is older years he was known for ending emails and conversations affectionately with, “Love Cars! Love People! Love Life!”


Thank you Mr. K for all that you have done for the automotive world. Our condolences go out to your family. You will be missed!

In 2012 Jack W was visiting the SF Bay Area on his way down from Canada. He heard about Z Car Garage and stopped by for UPREV tuning on his Z34 Roadster. We also discussed the possibility of force-induction via GTM’s newly developed (at the time) TD05 16g twin-turbo kit. The following year Jack crossed the border once more to visit ZCG and make the commitment to boost! We installed a GTM Stage 2  TT kit with their supporting parts including a 25-row engine oil cooler, automatic transmission cooler and valve body upgrade.

On the dyno the GTM Stage 2 kit produced 434hp/360tq to the wheels:

Jack’s Z was one of our first cars to receive the PLX Devices gauges which became popular on later builds.

We mounted the PLX DM-100 in the factory clock gauge-pod location:

We installed camber arms to complement existing coil-overs and after we performed 50 miles of test driving Jack flew down to SJC and drove back to Canada in his boosted beauty.

13k miles later we are happy to report that Jack’s GTM-powered 370z has been running flawlessly. He came back to ZCG to do a full inspection, oil change and a re-tune:

Taka’s Datsun 240z

BM12812 018

Taka Y visited us in 2012 for some maintenance on his pretty 1972 S30. Originally the classic orange in color, we love this metallic red shade as it shifts from burgundy in the shade to a brilliant ruby in direct light.

BM12812 013BM12812 014

In addition to sorting out the SU carbs we added Pertronix electronic ignition, did minor suspension work and cleaned up the fuel tank and all associated hoses:

BM12812 008BM12812 007BM12812 011
BM12812 005BM12812 001BM12812 002

After a few years of enjoying the Z Taka came back to ZCG for more suspension upgrades and clean-up work. Starting with the suspension we chose new rear lower control arms from TechnoToyTuning (T3), Eibach springs , KONI classic shocks and f/r sway bars:

BM101413 007BM101413 008

Here are the original rear control arms and new T3 adjustable parts:

BM101413 012BM101413 019

Both lower control arms installed:

The rear end also got treated to new mustache bar bushings:

BM101413 015BM101413 016BM101413 013

Up front the lower control arms and T/C rods were cleaned, primed and rust-proofed:

We installed a new clutch master cylinder and clutch slave followed by full hydraulic system bleed with Stoptech 600 fluid. New hoses shown below (L): On the right, Taka’s L-series oil pan gasket was seeping oil so we replaced it with a new competition piece:

Here is the pan coming off and new comp. gasket applied. A new oil pressure sending unit was also installed:

We replaced the old, worn motor mounts with new pieces:

New vs old motor mount isolators:

With the chassis, engine and hydraulics sorted we improved aesthetics by changing the wheels. We really do love the Panasport wheel and over the years they improved their casting/design. The latest offering is stronger and lighter with stunning finishes. Below (L) it’s easy to see the difference in tire dimensions…

103114 cam1 095103114 cam1 110

Taka’s 80′s era 280zx 14″ wheels were mounted on gargantuan 235/60/14 tires. The new Panasports are sized 16×7 (11mm offset) and shod with 225/50/16 Bridgestone RE760Sport tires.  Taka’s Z now has a sportier, updated look with performance to match thanks to this wheel/tire combo.

Enjoy The Ride, Taka. We love your 240z!
