The mk2 motor mount will bolt on to the passat engine. I don't remember how the turbo arrangement is done in the passat but think it will fit in to the mk2. You can always make litle adjustments. This is no problem if you are going to fit a larger turbo for the place of that tiny gt1749v and using a different exhaust manifold anyway. The wiring doesnt plug right into the mk2 fusebox buy it's not a problem. You can solder the needet wires. Mainly all ecu wiring runs in the engine bay. You need to get few wires to the inside though. Power for the ecu, IMMO, OBD wires, and some other which i don't remember right now. Compare the wiring diaghrams and it should be no problem.
