yeh its a 240mm dual mass from the AVF PD130 engine.
The main advantage being it will take a 240mm clutch rather than the 228mm 1.8T part, and bolts right on to our engines.
It needs a different starter motor as far as i can tell, and i've not had a chance to test the bits out to be 100% sure.
EvilSnow: the 1Z flywheel is from an old Audi 80/100 model, I had a few of them re-machined to take a 240mm clutch from an early S2 engine. Its not a quick fix unfortunately, as you need to find the flywheel, buy the clutch, and then have a machine shop redrill the flywheel to fit the clutch plate. Its usually works out as the cheapest way to an upgraded clutch for the 1.8T though.
