Hey man,
I am in the middle of a swap right now. I am swapping a JDM H22 and tranny into my 93 SI. It is really easy, but like he said you need the ECU from the VTEC Lude, and also part of the wiring harness. You have to have the connectors that plug into the VTEC solenoid. There are two. Email me if you have any questions.
