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 :D
