to get that sort of power you are gonna have to get rid of the supercharger as it is too small and wack on a turbo. The supercharger is good for about 14 psi I think after that it just blows hot air and no good.
gze internals are strong, easily handle 15psi, I think yogi ran his at 35psi or something for a few months before it blew and that was a $300 2nd hand bottom end hehe
above 15psi though u will need a aftermarket computer
as for the BOV I believe because the supercharger is on the engine side of the thottle bodies it won't do the turbo pshhh, I think luke tried hehe
