I think your problem was listening to your Nissan friend guy...Just get a 99 Civic Si or 96 and up GSR engine swap you'll be fine. You may want to get an OBD I ecu though and get an OBD II to OBD I Harness adapter, then you can use a B16a or 94-95 GSR ECU...I only suggest this because if you decide to go FI you may have less problems or you can add a Hondata setup with no problem.
