    To answer your underlying question, there are no real differences:
    b18a1 (1990-1991) was obd0
    b18a1 (1992-1993) was obd1 with 10 more hp than the obd0 version (some say cam, some say injectors)
    b18b1 (1994-1995) was obd1 with a different style intake manifold (still bolts to b18a1)
    b18b1 (1996-2000) was obd2a (different injector plugs, different distributor, different alternator plug, more emissions BS)
    b18b1 (2001) was obd2b (I think)
    All internal Parts are fully interchangable between the engines, as well as most of the external parts.

    well, you need the tranny for the 90 integra, which you should still have, then you have to use the 90 integra wiring harness, with the 90 integra distributor, the 90 integra injectors, and the 90 rear bracket, side bracket and side mount. most of this stuff you should have from the engine you took out of the 90, except prolly the dizzy and the injectors, and the harness.

    Is the 90 integra same as 92? My friend wants to swap the b18b1 engine into a 92. I got the engine out of a 95 Teg LS. I have the axels, harness, axels from the 95. If its the same as the 90 then I know what I need. If not, then what would I need?

    the only big difference between the 90 and the 92 is that the 90 is obd0 and the 92 is obd1
    your friend may need a 92 integra harness, other than that the 95 is obd1 and so is the 92, possibly some vacuum hose changes, but nothing major.

    The only thing that will bolt up like stock is another stock replacement b18a.

    you can use your tranny with any b-series, including vtec variants, but it will require wiring and computer work (and finding an automatic vtec computer is difficult)

    Yes, correct. Any B-series engine will fit, although you already have a B18, so I would not advise swapping down to the smaller B16 as it has less torque than your current engine and your car's auto transmission will NOT be a good match for it.

    Your best bet is probably a CR-V B20 engine. That would basically be a bolt-in as long as you use your current engine's accessories. If you want to add VTEC, you can swap a whole motor just swap a VTEC head, but you will need to find an appropriate ECU and get it chipped to run your setup, like Briansol noted.

    Is there something wrong with the current engine? You could just add an intake, header, and exhaust and see whether or not you like modding your car. The B18 you already have is not a terrible engine.

    You're in a tough situation. You have a 25 year old car with an automatic transmission. Unless you have a lot of mechanical knowledge, you're not going to be able to do much. It wasn't made to be a fast car. If you really want something quick, your best bets are to either A) slap on a turbo kit, B) put in a b20 as suggested, or C) sell it and use the car money and extra cash to buy something quicker. Building up an old car with an auto tranny isn't the best option.
