Hmmm... Ive been looking at doing a turbo change. Was thinking gtx3582. Because, Im going to stay on 98. Car makes 322rwkw now. Either turbo I will need to get, valve springs, wastegate/flapper mod and retuned. The problem is, for the cost, if it makes around 360 with the gtx3576 it's not a great increase for the $. Where as the gtx3582 will make 400. This is my dilemma.
