I have a 1987 4runner it has a 22r fuel injected motor that is no good I have a 22r carbureted motor what all would it take to put it in any one done this before

It's not that hard, motor mounts and all are the same, but you will have to do something with the EFI ECM and probably the emissions ECM. Depending on what the 22R is out of you may have to swap an oil pan or exhaust manifold.
