Hey "Wild" FWIW
I think this may be the first time our opinions differ. I wouldn't worry if he was talkin turbo boost, I agree within reason the stock pistons will stand up to that. NItrous is different, more sudden, higher tempatures, different chemistry in the combustion chamber.
I'd be very careful adding even a 25hp shot....you'd probly get away with it ok, but I'd be careful. Definitely not the route I'd go.
