Our adapter plate will marry the Porsche 996/997 non-Turbo/GT manual transaxle to the Chevrolet LSx engine/accept an OEM starter(GM 12617229), while our motor plates bolt into the factory Porsche engine mount location(s), suspend the engine from the cylinder heads, and work for RWD or AWD variants.
