Well, if you went turbo, the 4-2-1 header would be non-existant. From what I've heard, Bosch +4s are horrible on the Tib. The Spark Plug Wires won't do much for performance, more for how your car runs.
After clearing up those factors, I'd say at 7psi you'd make right around 200hp to the ground. This would be accounting for proper fuel management, a matched bore on your intake manifold, and an adequate exhaust system to expell the wasted gasses from your engine.
