Well it looks like you can either get a higher comp ratio or a lower one, and the other stuff just reinforces your engine internals so it can handle a strong amount of boost or nitrous without blowing up. You wouldn't see anything but an oddly performing engine if you bought that kit without a controllable ecu and a professional tuner.
