well it really depends on where you want to take your 18R.
if you want forced induction, keep with the 8.3:1 pistons you have in the standard 18R-GEU, since they are plenty compression happy for a solid 7psi or so (im told)... and the rest of the work wil follow on from having the forced air bug....
if you dont want to ram air into your engine and simply let atmospheric pressure do that for you - then get yourself the 9.7:1 pistons (straight swap) and the early model camshafts (will have either 88210, 88211, 88230 or 88231 stamped on them) since they have the most aggressive profile. You certainly would notice these ghains.
