Gary P is a long-time customer and huge motorsports fan. He owns a rally 510 and acquired this 240z from another ZCG customer. While enjoying the Z on his commute Gary noticed a loud humming sound and came to us for diagnosis. We discovered a right-rear wheel bearing failure and replaced them new bearings.  The rear suspension was also freshened with new rear lower control arms from TechnoToyTuning (T3):

New wheel bearings followed by pictures of the tired, stock rear control arms/bushings:

 

New T3 control arms:

 

The soft brake lines had also seen better days with rubber cracked and seeping. Not safe!

 

We replaced them with new hoses:

 

Gary is ready to get back on the road again!

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:

  

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

 

 

More shots of the front/rear calipers vs OEM:

 

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:

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!

 

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.

GTM manifold details:

Final installation looks ultra clean and very subtle:

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:

 

With 455hp/379tq to the wheels Jack Enjoyed The Roadtrip back to Canada, another happy ZCG international customer!

 

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.

 

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:

 

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:

 

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

 

Both lower control arms installed:

 

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

 

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…

 

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!

 

At Z Car Garage we love to help enthusiasts by installing customer-supplied parts. Eric R purchased these hot rod goodies online and came to us for installation on his 2014 370z:

 

Stillen Gen 3 Intakes are a proven way to increase mid to high-range power on the VQ37HR:

 

Install showing filter location:

 

 

The 370Z has been discovered to suffer from high oil temps when exposed to extended periods of spirited driving. Once oil temps reach a specific temperature, the vehicle’s ECU will put itself into a “Limp Mode” cutting the power to the engine.  The solution? An engine oil cooler, this one is a great unit from Z1 Motorsports:

 

Stainless steel braided brakes lines can also help with pedal feel compared to the stock, rubber lines:

 

The perfect balance to improved intakes is to upgrade the exhaust side. Eric chose the TDX cat-back system from Fast Intentions. Aside from the power gains this carbon fiber muffler option also saves weight:

 

And yes i does look great too!

 

UPREV tuning maximizes power gains from these bolt-ons. The Stillen intakes and FI exhaust pushed power past the 300whp mark to 307hp/258tq at the wheels:

 

With UPREV tuning we extracted 10hp more to the wheels for total of 317hp/258tq, noticeable improvements in mid to high range hp and torque:

How can we help you add power and performance through bolt-ons on your Z or G?
