distributor replacement Q (1991 with b20z)

I had someone swap a b20z into my 91 integra and I am currently in need of a new distributor as the bearing for my current distributor is making a whining sound as a result of the bearing seizing up. My question is do I order a distributor for the b20z (obd-2) or b18a. I believe my spark plugs off of my b18a were used when the swap was completed. Any advice is greatly appreciated, thanks in advance!

I would replace it with one from a 91, or similar obd0 distributor. Otherwise your harness won’t hook up to it without either a conversion harness, or rewiring it with the connectors off your old one.

what color are the plugs gray or white?

im not talking about the spark plugs
