How can I tell which obd conversion I need? Hot can I justify wether my swap is a obd;1,2,0 ? My theory was that if its B16a2 it would be obd2? Sorry this sounds really dumb but it's just one of those things I haven't learned yet

Well, generally any US B16A3/B16A2 can only be either OBD1 or OBD2, we never had factory OBD-0 B16A engines in the US.

If the motor is totally stock and hasn't been tamperered with at all, the easiest way to identify an engines OBD type, imo, is by quickly looking at the distributor.

distr. has 2 grey plugs -- OBD1
distr. has one big square plug - OBD2

OBD2a/OBD2b engines are the same when it comes to the onboard electronics (injectors, distributor, alternator, sensors, etc). Only big difference is the actual ECU and wire harness.

 

Thanks for the input I know my dizzy is a obd1 but how will I know if I need a OBD1-OBD2? Does the ecu have a certain code or number that will let you know?

It depends on your vehicle's OBD type.
If your car is OBD1 & the engine is OBD1 then the electronics are 100% compatible with your car, everything should plug n' play if you reuse your exsiting engine wire haarness.

If the motor is OBD2 and your car is OBD1, you can either convert the engine to OBD1 spec by getting OBD1 electronics for it (dizzy, alternator, & injectors) and use your existing OBD1 engine wire harness on it.

or

you can leave the OBD2 electronics in place and use a 96-01 US OBD2 integra engine harness (which will plug n play in an OBD1 civic/itnegra). Doing this will allow you to keep the OBD2 engine electronics, but be able to use an OBD1 ecu to power the engine.
