so i have a 93 integra. Decided to replace the b18a1 with a rebuilt b18b. I was taking parts off the old motor for the one going in and i realized on the back of the block theres only 1 sensor compared to the b18a1 having 3 sensors, whats up with that? The car was obd0 and id like to jeep it that way for the time being so that i can use my stock harness and everything just dont really know what to do about the difference in number of sensors. Also, there is not a spot for the breather box for the pcv system on the back of the b18b block and the pcv valve isnt on the valve cover like others ive seen???? Any helo would be appreciated.
