Ok im going to running this particular turbo on a Gsr motor.. With forged rods and pistons. 81.5mm bore Stock head.

I ran the turbo on stock internals and it felt good up to 9psi but i only got to do it for about 2 days before the oil leak caused me to spin bearings..

Anyways im trying to find out if anyone has this particular turbo? What thoughts you have about it? How restrictive this turbo is oppose to a .63 exhaust? Im kinda worried because im hearing that people with the same boost on this turbo i have are making less hp then people with say a .63ar compressor.

My goal is only about 350whp... Im going to be using hondata S300 I also have str throttle body and skunk 2 intake manifold hopefully that will help a bit.. If anyone can help me out with suggestions or with how they feel about their particular setup with a similar turbo i would really appreciate it.
