I used to have a 91 teg. You can't switch the seats easily because the automatic seatbelts have to lock into the seat. What I would recommend is going to a junkyard and just finding a new seat that is in decent condition. You can probably get one for like $25-$50 depending on where you go. Honda Accords from 90-93 also have the auto seatbelts and the seats from them may also fit the integra. I'm not 100% sure but I think they do.
