Well since this post was started i have changed plans a little. I am working on a powerdyne S/C instead of the turbo, basically i got lazy and also wanted to make it easy to remove for warrenty reasons. The 3.5 should handle 10-11psi if i can figure out the fuel. I am planning on about 8-9psi with the current puttey i have on it. It is still in the design and fab stage but i hope to get it done this summer.

Can the 3.5 handle 10+ psi?
My turbo experience is limited to the SR20det, RB25dett, KA24-t, 4G63, B16, EJ20t, EJ22t and the VG30dett. The VG30 was a holy nightmare because of the limited room in the engine compartment. I don't see how the VX is going to be easy to plumb, but then again, I don't have half of your fab skills.
What kind of manifolds are you thinking of?
