Hey I'm in the process of swapping in a b17 into my 93 right now. You can read my thread on b17 questions in this forum. First off not all obd 1 cars are created the same. My engine harness off the b17, which is a b16 with a different crank and rods, connected right up to the DA obd1 chassis harness, HOWEVER, not a single wire lined up across the connector. Your ECU should be set up for any obd1 ecu vtec or not the pin outs are the same. I did notice my DA didn't have a Blu/blk wire for the vtec pressure switch and a Red/blu wire for the knock sensor. Maybe the Japan XSI Integras are more compatible I'm not sure. In my opnion it would be best to get the whole front clip, then you get RHD too! Good Luck, it ain't an easy motor swap.
