Won't know what needs to be replaced until you pull it apart a little bit. I expect that
most of the damage is to the aluminum suspension parts and the underlying steel will still be straight enough.
I'd expect to replace the steering rack, maybe the aluminum subframe, entire right suspension, complete right radiator unit, front plastics, hammer out the tub a bit.
Fun project. I wouldn't expect much gain from flipping it, but as a project and driver it should work out well.
