you will need an Si rear mount and Si front upper driverside mount. You will have to use your stock civic harness, the Integra has a 2 piece harness and the civic has a 1 piece harness. Your better off finding an EX harness from a 96-98 Civic since it already has the vtec wiring. Are you getting a full swap as in axles, shiftlinkage?? You can find an OBD conversion harness on Ebay, or try www.jdmshit.com Try to Find an OBD2 GSR or LS motor would be a little easier
