Eric T hails from Benicia, CA and he is one of the key members of Inconceivable Racing along with our customers Matt M and Rasheed B. This is a group of enthusiasts that got into Z cars and are now obsessed with taking them to open track days and events like Shift Sector. What is really cool is that both Eric and his wife run their HR-powered 350z cars together at the track!
Here are the couple enjoy their Z cars at Laguna Seca. It is a small Z-car world and we have worked on Eric’s wife’s 350z Convertible because it was our man William’s!
Eric had been to several independent shops and wasn’t really happy. Rasheed told him about ZCG and we met with Eric to help sort his Z. After driving at Laguna Seca, he was frustrated with corner entry and exit speeds. This was a result of not putting power down effectively through the open differential on his Base-model Z. Our solution was to install the OS Giken limited-slip unit:
Here is the unit being installed with a 4.08 gear, all new bearings and seals. We also added a NISMO Diff cover:
The diff all buttoned-up and installed on the car:
With the car up on the lift we noticed one of the bushings in rear subframe was leaking. The subframe was pulled and all bushings were replaced with with SPL solid bushings. The diff received Whiteline bushings:
The aftermarket exhaust system was rubbing on the rear chassis brace and had a rubber pad wedged in between as the solution from a previous shop. We fixed it:
The exhaust was also rubbing on the rear sway bar, where a heater hose complete with hose clamps was used as an isolator. We fixed this well:
Motordyne ART pipes were installed and the Z was retuned with UPREV:
On the dyno we found peak gains of 7hp/11tq for a final 303hp/265tq to the wheels. More importantly the gains can be seen throughout the rev range:
After we performed this work Eric attended a 2-day race event at ‘Seca for his birthday. He was super pumped with the Z and it performed well. He’s a ZCG believer. Enjoy the Ride, Eric!
We are proud to be a sponsor of the 13th Annual 2017 Japanese Classic Car Show September 23! The JCCS is a J-Tin lover’s paradise and it keeps getting better every year. Take a look at the poster above and you might notice a familiar black Z car. This year our OS Giken TC24 powered 1971 Datsun 240z will be displayed as one of the featured show cars, from the press release:
“America’s Most Exotic 240z” does have a nice ring to it! You can see the original article by Mike Garrett over at Speedhunters HERE.
Z Car Garage will have its own booth at the show, so please stop by, check out the Z and say hello!
In case you missed it, our coverage of last year’s JCCS show is HERE and you can see a brief history of the TC24B1Z powered 240z below:
Over 30 years ago OS Giken created the first dual overhead cam (DOHC) 24-valve cylinder head for the Nissan L-series engine: The TC24-B1Z.
Z Car Garage in partnership with OS Giken debuted the first North American (LHD) Datsun 240z to run the TC24-B1Z at the SEMA show in Las Vegas, CA: ZCG at SEMA 2015
We want to share how this mythical cylinder head sounds, looks and drives.
Turn up your speakers and enjoy!
We met Rich G when he called us about the suspension on his 2011 G37 Sport Coupe. After visiting a wheel shop to get new wheels/tires installed he reported the car was bottoming out and felt very unstable. Rich sought out a specialist (sound familiar?), called ZCG and met with Rob to assess the car. We put the G up on the rack and noticed installation of very aggressive H&R lowering springs. The springs and aggressive wheel/tire fitment made the car bottom out and also cause excessive camber wear.
We immediately changed the springs to a set of Eibach progressive rate units which are fantastic for a car that just wants to be slightly lower and enjoyed as a daily driver.
The wheels were wrapped in new Hankook v12 evo S2 tires and SPC F/R control arms help keep the suspension properly aligned. The G still has a nice stance:
Rich’s son is a younger fellow and removed the rear muffler so we put it back on for Rich. If you are going to wear tires like an adult sports car…it might as well sound like one too:) After the G was sorted we heard from Rich a few weeks later and he was super stoked with the way the car rides. He was also happy to report perfect tire wear too.
So here we have another great example of the specialty shop working for you! Enjoy The Ride, Rich!

Are you ready for the greatest event during the Monterey Car Week in August? The Rolex Monterey Motorsports Reunion is 8/17-8/20 and you don’t want to miss it! There will be several iconic Datsun race cars and your favorites from the 60s to the 90s.
Our friends at ZONC have arranged for a NISSAN corral to park your car close to the track and avoid the madness(and distance) of general parking:
