I understand from a friend that the EFI system on the 22R engine is not interchangeable with the carburated intake. That the head is different on the intake side. My question is this, if I take the head and the intake mandrel for the EFI, and all the wires and etc. off a 91, will that work on an 86 that now has a carb?
The injected version is the “22RE”.
If one were an '89 and one were a '90 I’d say maybe, but I suspect the years are too far different. That 5 year span is one where numerous changes were made in the interest of emissions. And remember that your '86 has none of the sensors that were needed to drive the EFI system, and probably don’t have mounting holes for them.
