im looking for 200-300 hp on my built z6. not fully built to the ***** but machined factory rods,je pistons,minor head work, ect. just sold my t28 and everything would a t3 .60 trim be good enough? or should i get the super 60. or any other turbo's you would recommend?

 

well what else other than 300 WHP are you looking for?? You have to remember your displacement is only ~1.6L. That isn't that big. So you could make some power with a bigger turbo, but not reach full boost till top end, so you would be at a loss on the track and strip.

 

a t3 .60/.63 is going to be really pushing it trying to make 300whp. But since you have stock rods your really limited anyways. I'd probably just stick with that.
