I have done the job before on a 33. Its not overly difficult just time consuming.
the broken studs are no issue, a good drill steady hand and a set of rigid screw extractors have it done in no time.
but you will want to replace all the gaskets and all of the exhaust studs, also you will need a bit of coolant too for the bit you lose when removing the turbo.
I would put my hand up to do it, but im not able to for the next 2 weekends as i am very busy. If your still stuck after that give me a shout.
