Carlos S visited Z Car Garage to supercharge his 2014 Nismo 370z. At his request, we installed a Stillen supercharger kit with the larger intercooler (frozenboost) and full PLX Devices gauge package. After driving the Z for some time Carlos came back yearning for more power and inquired about a new air-to-air intercooler setup that was all the rage on the forums at the time. Keeping forced-induction limits and CARB status in mind with the 370z we started discussing the prospect of GT-Rs.
Within days Carlos was actively searching for R35s. After our buddy Lou S came down to the shop and demo’d his black 2014 GT-R Track Edition…Carlos knew he had to have one and became the owner of a 2015 R35 in Vibrant Red. In addition to being a cool dude Carlos also has a very supportive girlfriend, Amy, and two French bulldogs. And we all know that frenchies are the bee’s knees 🙂
Carlos couldn’t wait to start modifying the car and to keep him happy we installed a Boost Logic cat-back exhaust system and 90mm Quadzilla mid-pipe:
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, SpecialtyZ Flex-Fuel Set up and AMS Downpipes
When increasing boost levels it is wise to upgrade the factory, non-adjustable by-pass or blow-off valve (BOV). Here we used new, adjustable BOVs from Turbosmart:
Before/after shots of the new intakes and BOVs:
Installing the SpecialtyZ Flex-Fuel sensor kit. This key component monitors the ethanol content of fuel for running different octane gas/ethanol blends. Also shown are the ID 1300cc injectors and dual DW300 fuel pumps:
Using EcuTek software and help from our good friend Sebastian at SpecialtyZ we tuned the GT-R on 91 octane and ethanol/E85. On 91 octane we saw gains of 50hp and 62tq above stock for a total of 542hp/507tq at the wheels:
On E85, the GT-R made 632hp/612tq to the wheels. This is a significant increase of 94hp/105tq over the 91 octane tune and a whopping 144hp/167tq at the wheels over stock output!
Carlos is extremely happy with his 600whp Nissan GT-R and he has already ordered a Stage 2 kit from Spray Racing with upgraded turbos…to be continued but for now Enjoy The Ride!
