H22 conversion
 

I currently have a 2k accord with the 2.3 ulev 4cyl with auto tranny. I hear everybody talking about converting to an H22 motor. what else would this involve? I can get an H22 and auto tranny from a prelude. But,is it going to be a plug in and play or will i need to harwire stuff,change fuel pump and ecu,etc.?
