I currently own a 1999 Honda Civic LX, and am looking to do an engine swap. My first question is, can anybody tell me what OBD my car is, because if I understand it right, doing an engine swap that has the same OBD is much easier. The second part to my question, is what engine would be an easier swap into my car. A B16A2 out of a 1999 Si, or a B18C1 - B18C3 out of an Integra? I am looking to do a swap that won't be too hard to do considering I plan on doing it in my garage. Any personal input or advice is appreciated.
