    you need to fabricate all new engine and transmission mounts - the JDM D15B won't bolt to the 87 transmission (different bolt patterns) - you will need to use the 88-91 CRX/Civic L3 transmission, use custom axles and custom shift linkage - you will need to use the 87 engine wiring harness and make a bunch of changes to it in order to run the electronic advance ignition and VTEC - you will need a OBD0 to OBD1 ECU jumper and OBD1 ECU, like P28
