should be a direct swap... i put a 94 b18b in my 92 hatch, and it was really easy... however, i didn't have P/S... and didn't keep the A/C..... still should work out fine...
use the b18b compressor, and the lines from the integra, and you sholud have no problem.. the lines can be hooked up at the junction under the factory airbox, and should directly connect... as for P/S... depending on the arrangement of the lines, you may just have to hook up your civic lines to the teg p/s pump
