one suggestion, buy an S15 turbo... it will make a HUGE difference. its like a monster next to the T25 and you can push roughly 300whp (depending on what type of dyno youre on) with it and a power FC on E85

That's awesome man, my plan is t28, 550's and enthalpy tune or powerFC. Eventually lol but for now I just want to get all the maintaince done and go ahead and fix the typical stuff that goes out. I just bought the car two weeks ago lol.
