I am swapping a 1989 Honda B20A5 Prelude Si Motor into a 1993 Honda Accord. The block is to be Bored from 81mm to a 84mm, and the heads, intake, and header are ported and polished. A mild stage 1 cam is to be installed. I need to know if the 1993 Accord ECU can be changed to run the DOHC motor I will be running or will I have to re wire everything.
