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. 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:

Dyno Tuning

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!

At Z Car Garage we love working with the later model Z33 and Z34 cars, from full forced-induction builds to bolt-ons. Brian S brought his 2015 Nismo 370z in for a full Fast Intentions exhaust system installation:

   

We enjoy working with Fast Intentions and their products are high quality/proven. Brian purchased his exhaust from FI and we installed it.

OEM vs FI:

  

We think the latest Nismo Z34s are the best looking and performing editions of the model. For a no-frills sportscar that only a Z can deliver these are great value and the price of entry is coming down significantly.

  

Brian will be coming back for a dyno tune and intakes to let that VQ37 sing!

 

We are fortunate to work with fantastic clients and as a result they are the best form of advertising. Carlos H and Scott C met at the same gym. We supercharged Scott C’s G35 several years ago, and he was kind enough to refer ZCG to Carlos for work on his 2016 Nismo 370Z.  When we first met Carlos he came in for some bolt-ons: Stillen G3 intakes, Fast Intentions cat-back exhaust, and a UPREV flash:

FI cat-back exhaust:

 

We also installed FI long tube headers:

 

On the dyno immediate gains of +12hp/16tq to the wheels were seen with the intake and exhaust:

 

The best way to maximize gains from bolt-ons is perform an ECU tune. UPREV tuning yielded further gains for a total of 323hp/266tq to the wheels:

 

Carlos came back for suspension upgrades and we all know Rob loves the KW V3 coilovers:

Next, we installed our favorite sway bars from Hotchkis:

Carlos is Enjoying The Ride…and we have to say the 2015+ Nismo Z34s look so good!

 

Dennis K comes from the East coast and moved to Bay Area for work. Once here he wanted to find a specialty shop to help him with his G37. He already had coil-overs and larger wheels/tires but no camber adjustment. His first visit to ZCG in October ’16 included installation of SPC F/R cambers arms and new Bridgestone S-04s tires.

 

Following a full alignment we also raised his coil-overs slightly to cope with the wonderfully smooth roads we have here in the Bay Area. Finally we added our favorite sway bars from Hotchkis, and performed some cleanup work.  As always, the performance and modifying bug kicked in. Dennis came back to us in March of this year after he had waited for his Fast Intentions cat-back exhaust to arrive:

 

A Stoptech Sport-kit rounded out the chassis upgrades. After the cat-back was installed, we change the oil, and installed several parts that Dennis had purchased online including a strut bar, grille and CF diffuser:

Thank you for letting us work on your G, Dennis!

Allan came to ZCG because he was getting a Check Engine light resulting in smog issues. We found that his catalytic converters were well passed their lifespan and decided to get a set of low-mileage cats for testing. While the FX was in the shop we installed some Fast Intentions high-flow cats:

  

The engine was treated to a Stillen intake, and UPREV tuning. Since this car is awd, Rob UPREV streetuned it.

 
Allan is super stoked and enjoying the FX. He’s also been coming in for regular services and we love keeping folks on the road!
