Sorry been busy. I converted the dpfi to mpfi, the car it went into is a 90 civic ex, so the only major change in have to make from my mentors opinion is change the distributor, ECU is for manual trans, wiring harness goes with mpfi, does that sound correct ? Only need a ex/si distributor to put in the motor, as it plugs right in. And a fuel line no big deal. We took out of this car a d16b vtec that was powerful. Not sure don't remember to he specifics but it now is in a shop drag car and just dropping in and racing it was high 14 15 with an ECU for auto but running as manual. No adjustments just dropped in and raced. Exhaust is straight out the hood. Civic coupe. But ok question is about needing a distributor only for the d15b that has been changed to mpfi intake manifold.
