Neither is VTEC. So I want to see pictures of the VTEC ZC head. As for the ECU to run a VTEC head, you can use a P08 IF you are running a 1 wire o2 sensor. If you are/want to run a 4 wire o2 sensor you need the P28. P08 is JDM P28 is USDM. Another option is what I did, a P06 reprogrammed to run the SOHC VTEC program. Contact mtber (John Vega) and he'll hook you up. ONE MORE THING...Your distributor HAS to be the same OBD as the ECU in the ED (We live in USA not Japan). So in summary you need a P28 or equivalent ECU with proper o2 sensor, OBD 0 -> OBD 1 jumper harness and an OBD 1 distributor....Whew
