OK... i have a 89 crx si.... and i am looking to put in a COMPLETE 94 integra ls motor with tranny and ecu and wiring harness and all the other stuff. i think it is a obd1 and my car is a obd0. i herd that im going to have to change my injectors, ecu and wiring harness and more things to do this. if im doing the COMPLETE ENGINE SWAP with tranny ecu wiring harness and all.... will it drop right in just like a obd0 engine would???????

 

You will need the HASport hydro tranny mount kit and a OBD0 to OBD1 conversion harness.

 

You can keep a B18 OBD 1 if you want by using a 90/91 integra B18 ECU.
I would just convert to OBD 1 since you have a OBD 1 ECU and dizzy.
