Not saying I will but this specific turbo: Turbo, but would this be ok. I have a dohc zc. Looking for 300whp which I'm guessing is 345-350 at the crank. From garrets web site I figured I would need somewhere around 38lb/min air with 2.4 pressure ratio. Based on that map think I have it right, its in one the center lands, but not sure about surge or choke limits? Ohh and yes, I have upgraded internals.
