any b16a can be any obd, unless you want it to be obd2, then you need to change out the oil pump and have a sensor on the oil pump aimed at a gear on the crank shaft. If there is no engine harness then you can tell if its originally obd2 by that. other than that, they dont have an "obd" per say. Are you wanting to put it in your car, if so, what is it and what motor is in there.
