Scrap yards are full of 1.8 motors mate. Go down and see what they have, get the flywheel, the clutch that's on it and nick the VR sensor bolted through the box.
Mitre cars (think that's the name) in south shields charge about a tenner for flywheels.
If you need a hand, me and my mate Andy with the MK can bring our cars up and let you see how its done. Where abouts are you? Gods allotment is a very big place
