would doing a pi swap increase the compression rate to a rate at which i would no longer be able to supercharge it? if it is raised then how does the 99-04 have such a low compression ratio? and how could i get the ratio down to the point where i could supercharge it?

you can still supercharge it...just not anything over 10psi........the compression is a little higher in npi cars because of the diffrent pistons.....if you get the swap you can get new pistons to lower the compression...your welcome

Jlaw speaks the truth Get different pistons or thicker head gaskets to lower the compression back down. And get a built bottom end while your at it so you can add some serious boost

cobra pistons n rods. forged crank. built pi heads + a blower cam and youve got a serious monster waiting for booost
