My brother is working on a project truck he picked up: 86 4runner with a factory turbo, blown motor. He's dropping a rebuilt 22re out of a 91 4runner into the 86. Is it necessary to swap the harness/ecu from the 91? Other than maybe an annoying constant check engine light, is the fuel/air delivery programing significantly different enough between the turbo and the n/a version to cause a performance issue?
