At Z Car Garage we have been maintaining and modifying late model Nissan/Infiniti sports cars since 2004. From Z cars (Z32, 350z, 370z) and R35 GT-Rs to G35, G37, Q50/Q60 cars we look forward to working on your vehicle. Efrain S visited us from Sacramento with his 2019 Infiniti Q60S Silver Sport for basic performance upgrades from AMS Performance including their AMS Heat Exchanger and AMS Air intakes and a Z1 Motorsports Blow-off Valve kit:
The new heat exchanger compared to the stock unit and installation:
Straight from the factory, the VR30DDTT is an impressive motor. The Hi-Output version is rated at 400 hp and 350 ft-lbs tq, underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob dyno tuned the Q using EcuTek. Baseline power was 333hp/314tq at the wheels. With the AMS parts and tuning final numbers were 412hp/452tq, gains of +79hp/138tq:
The VR30-series responds so well to bolt-ons and gets us excited. It’s almost like Nissan has comeback full-circle as the VR reminds us of modifying Z32TT’s in the 90’s: big gains with just few upgrades. The Q-series cars are really well-suited to the upgrades too with a very comfortable ride and massive hp/tq when you want it.
Here is the Q on the dyno:
Efrain was very pleased with the power gains:
“Honestly man my experience with Rob from start to finish was amazing. I could tell he loves his job, loves what he does and energy was on 100%, 7 days a week. Once I got the results back from the tune I was blown away I thought I was maybe going to see about 400 horsepower to the wheels at the most and he got it over to 412 with 450 torque, I couldn’t believe it. My bolt-ons are flawless, could not be anymore happy with the work from you guys and the whole experience I love the car thank you guys.”
Enjoy The Boost Efrain!

Rikio’s 2017 Infiniti Q50S Red Sport came in for basic performance upgrades from AMS Performance including their AMS Heat Exchanger, AMS Coolant expansion tank and AMS Air intakes:

Straight from the factory, the VR30DDTT is an impressive motor. The Hi-Output version is rated at 400 hp and 350 ft-lbs tq, underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob dyno tuned the Q using EcuTek. Baseline power was 348hp/331tq at the wheels. With the AMS parts, FI exhaust and tuning final numbers were 388hp/424tq, gains of +40hp/93tq:
In addition to the EcuTek flash Rikio also received the EcuTek Bluetooth adapter for map access for remote data logging, valet map switching etc. Here is the Q on the dyno:
Enjoy The Boost Rikio!

We met Kenin in 2012 when he visited ZCG with his Infiniti G37 IPL. After working on the G, years passed by and Kenin reached out to us having purchased a 2018 Infiniti Q50S sedan. He saw that we were working with other customer’s Q50s and asked if we would be down to tune his. We happily obliged, especially since Kenin’s Q50 was rear-wheel-drive.

With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Kenin’ Q received several parts from AMS Performance including their AMS Heat Exchanger, AMS Coolant expansion tank and AMS Air intakes. We also intalled his strut tower brace:

Rob was eager to tune the Q using Ecutek. Baseline power was 359hp/374tq at the wheels. With the AMS parts and tuning final numbers were 400hp/449tq, gains of +41hp/75tq:
Enjoy the Boost Kenin!
Special thanks to Seb at SpecialtyZ for helping us!
One of the best parts about ZCG is the opportunity to perform multiple builds for a customer. We met Mike J in 2008 when he brought his G35 Coupe in for some modifications:
Mike added some tasteful HRE wheels (one of his signatures) and we did a full build on this car including a Vortech supecharger with ZCG supporting mods. He enjoyed the G for a few years and sold it to a friend. The friend brought in the G for service, mentioning that Mike had acquired a 2013 R35! Sure enough, Mike called us up and said it’s time to spend another chapter together.
From past zcarblog posts we know the R35 GTR is a wonderful sportscar that blends in despite its impressive performance out of the box. Mike wanted a boost in power so we started with a host of Alpha bolt-ons from AMS including their downpipes and Y-pipe w/muffler:
Stock vs AMS 90mm catted mid-pipe:
Finishing the exhaust upgrades with an Akrapovic titanium slip-on exhaust system:
Our plan for more power included a complete flex-fuel setup for E85 tuning. Shown below are 1300cc Injector Dynamics injectors, DW300 drop-in fuel pumps, SpecialtyZ 3″ Intakes and SpecialtyZ Flex-Fuel kit:
Flex fuel installation:
Rob utilized Ecutek for tuning on both 91 octane and E85.
91 octane: 554hp/509tq
E85: 629hp/616tq
On E85, the dyno reveals huge gains from low rpm to redline. Mike we know you are Enjoying The Ride, thanks for bringing your GT-R to ZCG!
Matt M is another member of the Inconceivable Racing group and visited ZCG to supercharge his 370z Convertible. Here are a few pictures of the Stillen kit installation:
Matt came back to have us install some ART pipes and a Fast Intentions catback exhaust system:
ART pipes in place:
OEM vs FI exhaust system:
Being base model Z, Matt wanted to put slightly wider wheels on and sticky RE-71R tires for track days:
We love the PLX Devices gauge that neatly replaces the clock with a multi-function display to monitor vitals:
Finally, also installed new end links for his sway bars:
On the dyno we retuned with ECUTEK to maximize gains from the bolt-ons. Final numbers are 402hp/354tq to the wheels, peak gains of 32hp/24tq. After 4000rpm gains of almost +50hp/tq are seen:
