So I'm new to the whole forum thing but I've been driving and building my na 95 legacy legacy with a ej22. I recently blew a head gasket and it led to a rod knock, so I've been trying to do research to do a swap for a ej22t but I can't find anything specific to what I was wanting to do but I have no idea if it's even possible yet. That Beeing said, what I'm wanting to know is if I can put a ej22t into my legacy and set the turbo up on stand alone so I do not have to change the ecu and not have to deal with to much wiring. And if so will my ecu run the motor also?
