Hi guys I just bought a 1992 integra. I'm doing and engine swap to a B20B. I see that on the b18a1 is a sensor next to the oil pressure sensor by the oil filter and is another sensor next to it and the B20B doesn't have one there also I notice that the water outlet of the B18a1 has another water tube that the B20b doesn't have. The b18a1 also has another little black box in the block under the intake connected to a Pcv valve on the intake. Do I have to transfer the water outlet housing completely or I can eliminate that water hose? Do I have to also adapt that sensor next to the oil pressure sensor?

Please anybody can help me out with this.
