im actually doing an old 22r to a new 22r swap.... and the fsm will help out a lot, but there are still some major differences in the engine that will need to be addressed, im finding out right now that a lot of the emissions stuff is quite different. yes it might be ok, but you are going to need to pretty much swap over all the related efi equipment, almost would be easier to swap out hte whole engine that try to piece them together... the new 22r to efi wouldnt be so bad, but its the efi to old engine that may give you problems
