manifolds, and you will need a B5 oil pan from a passat/A4.... the AMU is internal water pump, engine code 06A. so a longitudinal oil pan is one thing, another is the oil pump pickup tube. its shaped different for longitudinal vs transverse.
the clutch setup i am not sure on, dont know much about the TT. if it has the same 15/16" 23 spline input shaft for the trans, the whole clutch setup from the TT should work. if not, then you will need 4 cyl Audi 1.8T clutch stuff.
starter you will need from B5 A4 1.8T as well, if it follows the VW starter placement for transverse cars vs longitudinal mounted cars.
thats about all i can think of for hardware.... but again, i dont really know what trans is in the B3, i am doing the swap into a Coupe Quattro.... but 01A and 01E have both 4 and 5 cyl patterns on the bellhousing....
one last thought? i recall reading somewhere the pressure output of the PS pump may be different as well. i did not pay too close attention to it as i switched over to a manual rack and ditched all power stuff.
