Caminperth,
Besides all the heat shields and gear that hangs off it, you will have to disconnect the oil line to the turbo, there is not much oil loss here. You can leave the turbo on the mainifold but if you dont you will need a new turbo to dump pipe gaskets and manifold to turbo gasket. To make things easier, it will need you to undo the exhaust just before the cat, so the fornt pipe can be free, it is just easier to have this undone. When you change the engine to manifold gasket make sure that it is one piece and not the 'VL" six individual piece setup. These single piece setups seems to 'blow out' on a regualar basis. One other problem you might encounter is the manifold bolts, these might break and I would be amazed if you dont break at least one or two on a donk that has done 80K's, it just the bolts have cystalised and become bittle over time. Have a welder on hand to weld a nut to the broken end and undo it this way, if it snaps again have a helicoil kit on standby to deal with this problem.
Anyway, best of luck my people might give you other ideas here, Im just giving you my experience on this subject.
Have fun:)
