So you want to throw all this stuff in your engine and yet you don't even know what some of those "things" do?
How about intake, headers, exhaust to start...While you are having that done, you can do some research to figure out how to spend your money.
Not trying to sound like a dick here, but you need to learn how stuff works before you decide what you want. Installers just want to take your money. YOU tell them what you want done...
