i have a 93 b18a which is obd1, i dont know whether to convert to obd1 or stay obd0. i dont know which one is easier either. how hard would it be to stay obd0. i also already have a obd0 distributer. please give me your opinion on which to stay too i am stuck in the middle. o yea its going into a 91 crx si.

 

you can stay obd0 with it, just run the obd0 dizzy, injectors and ECU.
That engine is one I don't mind leaving OBD0.
The VTEC engines see so much better gains as OBD1 using chipped p28's.
If you start modding the B18a. cams etc.. I recommend you go P28 and chip it for that engine setup. Otherwise OBd0 will be easier for you.
