Theres some pretty obvious differances you can see just looking at the pics.

Differnt inlet manifold to begin with, and Im guessing either twin coil, or individual coil with a differnt ignition set up.

I know they changed the Turbo, and Im sure they also run more boost.

Differnt ECU mapping of course, infact I should imagine a totaly new ECU with OBD II instead of OBD I.

Posssibly differnt cams.
