depends on which model EF you have.
If its a Si (mpfi), then its pretty easy, just a little bit of wiring.
If its a CX/DX (dpfi), then you'll have a good amount of wiring to do.
If you have a CX/DX read up on the DPFI to MPFI conversion to know what you're getting into in terms of wiring.
Other than the wiring you'll need b-series EF mounts, axles, DA (90-91 integra) half-shaft and b-series EF linkages. You'll also need the proper ECU (I recommend converting to obd1 and using a chipped ECU with a b20 program since there isn't an obd0 b20 ecu and the obd0 PR4 just doesn't cut it IMO). You'll also need b-series rad hoses.
