If you are keeping the car harness in the 88 you will need to swap the entire motor harness and change back to 86-88 injectors. Motor will work great but you have the electronic oil metering pump and no way to hook it up. Take the time to swap out the car harness if you can. Otherwise you need a different computer. Alternator hookup is different also. The 86-88 electronics stock have a hard time delivering enough fuel at high RPM. The 89-91 is actually too rich up top. If you decide to use the early setup add an adjustable fuel pressure regulator. PM me if you want some extra information. Too much to list.
