the manifold, NX kit, and teh 1600cc are going on the car on the weekend. Right now at 2-3 psi run slike stock ( 220whp) at like 7psi is like 300-320whp ( feels like, raced another 320whp Evo). But I am letting off at like 5500 or 6000. My wastegate is 17 psi, so I can easily blo wthe engine with that boost on stock fuel.
