Will I have any emission problems or wiring hook up problems trying to put a 1991 22RE engine with an auto tranny into a 1987 4Runner with an auto tranny. ECU compatible?? Dont want to start the project if I am into big headaches.
my best guess is that it should work... im not 100% but i dont think toyota would have made too much of a modification to the newer 91
22re... my guess is theyre the same... anyone else?MotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
