    A shift Kit and a clutch? It's one or the other.

    you don't put a shift kit on a manual car. and you don't put a clutch on an automatic car.

    He's an idiot. You'd need several bolt ons plus a cam to get that kind of power.

    the pull is usually done in done in fourth right? would the clutch really have that much to do with the number's anyways?
