Woah, slow down there, buddy. You must be thinking 5th gen, 4th gens need a mount kit and backdated electronics (or the use of a 90-91 B18A1 "LS" engine and matching OBD-0 PR4 ECU) not to mention the MPFI conversion.
If you want to do a B-series swap, you must use a B-series transmission, in this case the Integra unit, though I would recommend a 92-93 GS-R transmission if you can find one.
