Recently bought a 92 GS Integra (my 1st Honda/Acura,) been working on gutting her out and some other small stuff. Really clean 5spd thinking about PS and AC delete to save some weight as well. Did some research and looking into buying a B18 vtec head, what would have to be changed other than running an extra oil line and swapping out the ECU? Would I need to swap cluster and wiring harness as well? Thanks
