I have a 90 Hf crx, alternator died out and i am replacing today, but i was wondering if a alternator from a B16 will fit on it, i think its obd0. Dont know if mine is obd0 or obd1, anyone know if it will work?

 

A simple answer would be no,
but:
The wiring is the same,
but the pullies and the way it mounts are slightly different.

You could swap the two pullies,
then put a bolt through the lower mount
but you will have to rig up the top mount somehow...
so it might be easier just to find the correct one.

This was a "feasibility study" of using a stock alternator on a B16
[which would be the exact opposite of what you are trying to do..]
I swapped the pulley,and the lower mount was the same,but the top mount would have to be rigged up to work...

 

yours is obd0, but i'm not sure if it will work??
