So as I look for a turbo/supercharger for the Fusion and I've noticed that in general most say not to go over 8psi or some where around there w/ stock internals. Are the internals for the 2.3 duratech THAT WEAK? lI mean c'mon I most turbo's usually run anywhere from 15-25 psi and even 30-35 psi. why are our numbers so low? what about our internals make them so weak? is it the engine block? what?
