I am running a custom fabbed kit by Derek at ALL IN FAB.

Details:
-Precision 6265 .82 a/r
-unopened stock motor
- 3" exhaust system from the exhaust housing of the turbo to the tip of my muffler
-return fuel system on ID 1000cc's with a walbro intank and Bosch inline
-8an feed with -6an return and fuel lab regulator
-ALL IN catch can setup with modified valve cover
-Vanjen clamps at all connections
-Tucked radiator and backdoor intercooler
Combo (done by Derek)
-ALL IN intake manifold
-Custom Rywire harness and grounds.
-Competition stage 5 4-puck clutch.
As far as power is concerned, I am shooting for 550-580ish on E85 for high boost and 430ish for low boost. Only reason I'm aiming so high is because I don't DD her and only drive her on the weekends ;-). (Fridays and Saturdays-not for the entire day :-) ) I think it's doable by all means.
