Those 2.4l out of a stratus and all aren't really designed for boost, they are just designed to be a 2.4l, but regardless, the internals of the SRT-4 are better and some forged, and the block is stronger and more bulletproof... check out that link that Uberingram supplied and look at the internals and the block and all. I just personally believe this to be a slightly stronger engine and its actually meant for boost, it comes with it... just my $0.02
