search is your friend, but ill be nice. to get the most out of putting a pod on a vr/s, make a heatshield for it, so engine heat doesnt get to it and make a cold air induction piping from the bottom of the bumper or something to get cold air into it. just slapping a pod on will make the motor breathe better, but it will be breathing in hot air, which is not going to see any gains.
