Well a 22r from an '83 is a carb engine, there is no fuel injection for that year. A 22re has EFI, thus the r "E"...
Kind of depends on what you want. I love my EFI rigs for hard core wheeling since it runs practically upside down and all that but I also love the simplicity of my 1980 truck with the stock carb. If I was just going wheeling and driving to work, I would choose the 22re. If I was going to war with it, or say expedition travel, I would choose the carb for easier fixes in inclement conditions. Seems like you can always bandaid a carb truck together and get it home. The EFI, while it rarely needs anything usually requires parts when it goes down.
He has EFI on both engines, heres his other (basically the same) thread
