Im lookin to make about 220 whp on my eco. I figure a T3 super 60 at about 8 psi intercooled and proper fuel mods should do the trick. I just dont know what a/r to go with or how that affects the perfomance. Here is the trubo map for 8 and 15 psi (might not go this high but just in case). Also i would like to know at what rpm would i start to get boost and when would i get full boost if anyone knows.

You'd probably be best suited for a .48 a/r assuming it's a street car.
