Well i was thinking the ej22t as well I have the DOHC sitting around and would probly put them on the EJ22t block. A few questions there what do i have to do to make the EJ25 DOHC fit and work eff. witht he 22t block? Also what kinda wiring will i have to change, I'm an electronic repair tech so no of that scares me just want to know before i jump head long into it. Side question would finding a EJ22T ECU be a good thing for the engine esp. once it is turboed or will a stand alone or piggy back work better??
