I have the 2.5 with Sti head gasket (higher compression) I am running SR40 MRT full exhaust, up pipe, and cold air intake. RA gears & ACT HD street clutch and XAT flywheel. I dynoed 305whp 293tq on a conservative tune with pink injectors. A ton more low end and no waiting for spool to bring the hp. Car drives awesome!
