b18 OBD I or OBD II?

I just purchased a b18c1 for cheap but it has no distributor. how can i tell if it is obd I or obd II? there isnt a transmission or a vin plate. I was told if the distributor has two wires leading to it its obd 1 if it has one solid wire its obd 2. Please Help everybody.

Yup who ever told you that was telling you the truth, check out this page; specifically the 2 pics on the 6th post down: http://www.honda-tech.com/zerothread?id=550976

Oh and also you can see the date of the motor on the front of the block, there are circle on it, like this: http://img.photobucket.com/albums/v473/CivicSpoon/blockdate.jpg
If it's '96+ then it's OBD2

I dont want to sound like an idiot but im new to te wiring side of things but i have the same connector in the first pic. so does this mean its obd I? my friend also told me to look for a black box on the very top of the intake manifold. he said obd I b18's didnt have this box which is a vaacume operated sensor. I have this sensor.
confused.

:iagree: Not many ppl knows about that. I found that out by myself suprisingly ;)

The first pic is of an OBD2, it has just 1 plug; where the OBD1 has 2 plugs. So your motor is probably an OBD2.

mellowboy - Yeah I had no clue that there was even a date on the motors until my buddy got his h22. But the problem with the figuring out which obd it is by the date isn't always '92-'95 and '96+. That pic of the date thing is from my buddies JDM H22a, it's a '96, but it's actually still obd1. For some reason the '96's in Japan didn't change, wonder if that's the same here now that I think of it...

96 and up should be obd2? I dont know about japan but here its definitely obd2.

Yeah that's weird. I don't know of any other engine that's like that. I just have no clue why they'd make the '96 H22 the cut off year. When he first got it I had to look online cause I figured he got screwed and got an OBD2 engine and that it's be even more of a mess than it was, but apprently that's just the way they did it. Probably cause the Prelude isn't that common so they figured no one would care. Crazy Japanese.

Great thanks guys now i just have to figure out what year it is and ill be streat. oh yeah by the way anybody know where i can find an automatic p72 ecu and also does the gsr come automatic.

There was no automatic GSR, only manual.
