So the plan is to replace the F22A4 engine with a F22A6 to get the extra 10 hp. I'm doing this because the F22A4 is running on 3 cylinders...

I am guessing I need the cpu to do this since the F22A6 has "dual runners" Two mechanics (who have never done this swap before) are telling me that it may cost extra because its not the same engine and some things like the 02 sensors might be different etc.

I read the Chilton manual on the 4G accords and don't see any major differences. One question I have is the wiring different for this swap?
