you can do it one of two ways...convert your harness over to OBD1 by means of repinning or with a conversion harness and run the p28 ecu which will control vtec and have all the proper fuel curves....or swap to MPFI and run a si ecu and use RPM activated switch to operate vtec....not too big a deal..no matter what swap you do, you're gonna have to a bit of wiring with the dx
