If your Integra is a 92-93 your engine will work just fine. a 94-01 Integra or B16 Transmission will be required though.
If your Integra is 94-95 Almost everything will swap over.
If its 96-01 Seats, and Transmission will swap over, however you will need a OBD2 to OBD1 Conversion harness, or OBD1 Distributor, Injectors, Map Sensor, Speed Sensor, etc. almost all of this can be swapped out of the Civic hatch.
Seats, body panels, suspension, etc are not a 100% swap from 90-93 Integra. Seats, Suspension, etc from 94-01 Integra's are direct swap.

94-01 Tegs are sexy. I love the 98Spec models. Guess that's why I have one. I would trade either of my EG's for a 4door Integra in a heart beat.
