    It will bolt right up and to get it to work you will need a Y8 ecu (OBD2A since your car is a 97), fuel injectors from a Y8, a knock sensor, a Y8 5 speed intake manifold, IACV, and throttle body. All of this is assuming that your car is a 5 speed because auto needs different parts. You will also have to add wires for VTEC, the knock sensor, and change the IACV wiring around. Do a little searching there are hundreds of write ups that can tell you how to do this.

    Since it is auto you need the following from an auto Y8: OBD2A ecu, intake manifold, throttle body w IACV, knock sensor, and you will have to add wires from the ecu to the knock sensor and to the VTEC solenoid and pressure switch. You will also need Y8 fuel injectors.

    Are you sure its a 2001? I ask because D16Y8 engines were only produced for 96-00 Civics. However if it is still a Y8 then it will work.

    It is above the oil filter, but Y7s don't come stock with knock sensors. They do however, come with the mounting hole for the sensor.
