With just a minimal upgrade ..a stock GTR can really deliver good mid range torque and give the driver a Nice G-force. The basic upgrade such as
Bigger injector(1000cc Injector Dynamics) <-- stock is 570cc. At higher boost injector duty cycle will hit 100%
Downpipe(turbo outlet) <-- make your turbo spool better without any restriction
Knn Drop In filter.
