As far as I've seen, all of the b-series injectors are the same with the exception of the plug, so if you have the injectors from an obd2 motor, you will need to rewire the harness with obd2 plugs that will fit the adaptors, but that will be a pain. The b18a from a 90-91 integra will be ideal, and will plug right in with no modifications. I don't know if the d-series obd0 injectors will work, but I'm sure there are people on this site with the answer. The b16a1 injectors are NOT obd0, they are obd1, and will still require the same rewiring as obd2 injectors
