I find it extremly hard to give you an estimate on whp. Just due to the fact that so many things play a role in hp. But if I were to give you a good ball park figure, I'd say you're close.

What should I change, if I still have a chance. Any products anyone heard bad things about

Also is a 660 cc injector a good size for this turbo?
