Can anyone offer a little help? Have an 86 Civic dx. As it is now, the motor is in excellent running condition. The motor has been completley re-vamped and runs great. But it is slow as shit. I was going to swap in a 2.0 si from an 88 prelude. Easy way out so i wouldn't have to deal with the carberator switching to mpfi conversion. i would love to drop in a b-series or at least a zc, but unsure of the steps/wiring/ecu requirements for the swap. any help?
