Default Difference b/w JDM LS and USDM LS motors?

i know JDM LS motor is about .4 higher compression then USDM LS motor. so that means the PISTONS are different, but is everything else the same, ie fuel rail, intake manifold?, gaskets?, motor mounts, etc etc..

bout to swap in this JDM ls motor into my turbo charged setup and want to know all the details before actually doing it incase if i run into a problem.
