nah, all good. no trouble there. its a forum for a reason yeah i know turbos spin that fast, its being rebuilt with the n1 internals, so i was wondering if i could use the front end of the rb25's. either way, no point. if the frnt flows more than the rear can handle, not to mention hot air after combustion expands even more. i swear to god i had a blonde moment........ *facepalm*
