This is a friend's car. He has a full B18A1 Swap from a 90-93 Integra LS. OBD0 engine, OBD0 engine harness, OBD0 ecu etc. I'm writing everything I know in case any of it is useful. He has a bad alternator, and is wondering which alternators would fit. He has a F22 alternator from a 91 Accord he had with a 2000 F22 accord engine swap ( don't ask! ).

Is there any way of making it work?

How can you distinguish alternators between OBD0, OBDI, and OBDII?

What alternator options does he have? Since he's kind of on a tight budget. . . I would like to research his possibilities to be able to help him best. Thanks in advanced!!!
