Quick obd0 to obd1 questions

[ed_gm90]

Okay so I bought a 91 DA integra as a parts car, it came with a b18a1, but im not quite sure if it is obd0 or obd1? The ecu is a pr4, but i read around and i see pr4's can either be obd0 or obd0. So how can i identify if its obd0/1? The motor is going into my 92 civic dx hatch (obd1). I know i can use my harness, so am i just going to need a p75 ecu, obd1 dizzy and alternator? This is my first swap ever so be patient with me guys lol.

Thanks for any info yall can give me
