so i was wondering who can help me out here. all the research i do only leads me to more questions. i know for the h23 everything is plug and play or direct drop in. well minus the ecu. but i figured i might as well go all out and shoot for the h22a4 so i figured i hit up this website where i know i can get direct answers from my fellow honda buddies

 

Do research on this site the answers are there....

 

check the H22 swap thread.
