Has anybody hit 400hp on a non vtec set-up? Had me wondering. I was going to go for it over the winter. Right now I'm at [email protected] on a 57trim T3/T4 on a y7 with eagle/vitara combo. I was going to get a bisi cam and upgrade the turbo. Thinking about a SC61 and turning up the boost. I actually have a z6 head at the house, but I'm going to be stubborn and go for it.
