I just reread this and I have a little bit more input for you. I like that you want it done right, and the guys on this forum can definiely help. the key to making more power is adding more fuel and air into your engine. If you know that then great. Just think of what will help you to do that. Exhaust helps because it helps the air flow better through the engine, giving more air. TB, MAF and Plenum Also help with this. Gears help get the power to the ground more effectively...it continues. A supercharger is an awesome way to force more air in there, but there are a lot of costs also associated with it. I spent almost $1000 upgrading my fuel system when doing my supercharger. Do all of the important bolt ons...MAF, TB, etc. Then worry about the supercharger. You are going to need all of it later, so you might as well get it now. That should help.
