hi guys i live in australia and i own 92 civic with dual carby engine over the next week i will doing an engine swap from d15b dual carby to d15b fuel injection vtec i have notice there is nothing on the net that shows u how to do this swap so if i remember to take photos i will put up this swap for all people if it is needed thanks
 
Its similar to a dual point to multi point fuel injection swap minus the resistor box (in place of the resistor box is a special OBD1 harness plug with a consolidated metal clip which you can direct your primary and secondary injector power lines to it and re-direct it to your OBD1 injectors. There is also addition of VTEC wiring and maybe the O2 sensor if you are using an ecu which requires a 4-wire O2 sensor. You need to use the OBD1 MPFI P08 distributor, your current grey plug TD-40U distributor lack the cylinder position sensor & wiring and will not work with the OBD1 ecu.
