Hi guys this is the list of mechanical differences I could find on www.realoem.com

Anyone know if there are any other mechanical differences? I read on some forum that the turbo and camshaft is different but the part numbers seem to be the same.

Basically different part numbers for Pistons, Transmission, Driveshaft, front muffler and Rear exhaust
