With intake, exhaust, or suspension mods, the 986 S is in BSP. And the good news this year is that the WRX STI's got bumped up to ASP with the Vettes. Now the 986's competition is the Honda S2000. and Nissan 350Z..much better fight! Since the 3.4 was never a 986 engine, putting one in will bump you out of BSP.
