    whats the difference between the ls b18a in the 90-93 models and the b in the 94-2000 models? also does vtec matter when you're going to run a turbo?

    The b18a was in the 90-93 integras, it was obd-0, and it had a cable activated clutch
    The b18b was in the 94-95 integras, it was obd-1, and it had a hydrolic activated clutch
    The b18b that was produced from 96-2001 was obd-2 and had the hydrolic activated clutch

    This is not entirely correct. The 90-91 B18A1 was OBD0 and uses a smaller clutch disc/flywheel than the other B series engines, it is also the least powerful of the 1.8l non VTEC engines.
    The 92-93 B18A1 was OBD1 and uses the same clutch/flywheel as all other B series engines. It is more powerful than the 90-91 engine, but less than the 94+ B18B.

    The transmissions that came on the B18A are all cable actuated clutches, the transmissions that came on the B18B are all hydraulically acutated.
