HKS GT-RS Turbo Kit for 2002+ WRX/STi

Due to the overwhelming popularity of the HKS GT Sport Turbo Upgrade for the 2002 + Subaru Impreza WRX, HKS has decided to re-introduce the Off-Road use only bolt-on kit with one of HKS¡¯ newest turbochargers, the GT-RS. This kit features the same straight through downpipe, up pipe and Super Mega Flow Intake as the previous kit, but the GT2540R turbo has been replaced with the GT-RS and the split housing extension housing is now manufactured from polished SUS304 stainless steel.

The ball-bearing GT-RS turbo¡¯s outstanding power potential and responsiveness is an excellent match to the Subaru Impreza WRX¡¯s flat four engine design. This GT Sport Turbo Upgrade combined with an HKS Hi-Power exhaust, EVC, F-Con S, and larger injectors produced 246.3 wheel horsepower and 203.6 ft lbs of torque. These figures were achieved with boost pressure set only to 1.0bar.
