b16a2 to 97 del sol, depends on the OBD of the engine if you get it out of the 99-00 civic si, then use your old engine harness or possibly the one off the new engine if its uncut, 99-00 civic si or 94-01 integra axles, integra or 99-00 civic si radiator hoses and a radiator out of the 99-00 civic si or the 94?-97 del sol vtec. integra or any b-series shift linkage, and the ecu, I can't remember if the b7 is vtec and I don't feel like looking, if it's not then you have to wire vtec, check the swap articles for the pinouts, also you have to run the wires for the IAB, (also in swap articles) and possibly convert your IAC (also in swap articles)
if its an eg6 motor (obd1) then you will have to do all of the above except you must use the harness off your old engine, and you have to swap the injectors from your old engine to the new one. like civicsi said, check the articles if you get stumped, and if they don't help, then re-post with a specific question,
Im prolly forgetting something, but nobody's perfect, have fun.
