Well assuming you have the engine in there and all the mechanical stuff has been taken care of (eg. proper axles, crx si hub conversion since you have the hf model) next comes the task of wiring. Since the Y7 is obd2 and the car you're putting it into is not... you will need an obd2 engine wiring harness along with an obd2 ecu. The other option would be to do an obd2-obd1 conversion and use an obd1 ecu. Note that the wiring will be a pain in the a$$.
