I just got my 2001 Pontiac Sunfire GT it has the LD9 motor and it's a 5 speed manual, all I've done is straight piped it, I just am wknderign what are some things I can do to gain some more horse power, I don't want to go too in depth with the motor just yet. The reason being that I haven't decided if I want to turbo or supercharge it yet, comments on that would greatly appreciated.
