pretty much what dave said but also the transponder ring from ignition barrel, gear box, drive shafts, gear linkage (from gearbox to and including gear stick), front end body loom, cooling module, complete engine, radiator, all pipe work (cooling, fuel, air, aircon) engine mounts (all 4)
would be best to keep donner car until the new car is all running just in case any other parts are needed.
personally I would not bother swapping to a larger engine in a car that came with that engine in from factory, insurance will go up as it becomes an engine conversion. cheaper to find an astra z22se and insure that.
but that part is up to you and if you do it ask any questions you like on here, chances are its been done before and one of us will know the answer.
