If you're going boost, you don't want anything to raise you're compression. You want parts that will lower your compression accordingly to your build, boost levels, etc.
CTR pistons and boost - NO
JE, CP, or other forged pistons at a lower compression ratio (9.0, etc.) - YES
CTR cams and boost - NO
A specific turbo cam from an aftermarket company or GSR cams - YES
