I forgot about fuel... will be upgrading hte fuel pump, fuel pressure regulator, fuel rail, and injectors.... are cams and valves going to be that important?

also... turbo.... would you suggest a turbo over super, and why or why not.

That is a complicated question. I have had both and I would never go back. I wanted more torque, more topend power, something unique & that runs dead silent. The turbo provided all of those things. It is hard to describe and something you need to experience. The biggest difference between the 2 is at full throttle with an auto, the boost never drops through all 4 gears. With the blower, the boost drops and then builds again and as you go up in gears, the climb takes longer. Both at 12 psi on the exact same car, I trap almost 5 mph faster with the turbo. I will say that both have their pluses & minuses, but if you can swing the $$$$, I would definitely get a turbo. I'm speaking from real world experience on the street and at the track with both setups.
