No problems it will go straight in all you will need is the mounts get them off ebay. Gearbox will fit u have engine loom and ecu so you take out engine loom and ecu from car your using and use your loom and ecu inside car loom will be ok to keep! I fitted an rs2000 engine and gearbox into an old mk2 orion piece of piss just had to alter mount as it was old cvh and adapt wiring but your using a car that runs a zetec anyway
