does a mkIII gti motor drop in a mkII relatively easy? how tunable is the gti motor? do i need a chip upgrade to run with that? inever seen, heard or felt how they run. one thing i do know is that its not a vr which is what im going to swap into my mkIII shell after i get through the body work. isiT A 2.0 TWIN cam motor? how much torque & hp does these come with, and how much hp can be produce? even though im not going to tune it to much but just a lil knowledge couldnt hurt.
