Sorry for being vague, is my first time treading these waters.
I have access to(a friend would sell to me) an EJ 255 to swap in, but I'm exploring keeping its current engine and putting some sort of turbo charger on it. I will be doing it my self, well with the help of experienced friends. As for the wire harness, I am comfortable in that area.
I have a subaru XT 6(ER27) and a WRX(EJ255 turbo) engine laying around and I would like to put it in the XT 6. What kind of modifications would I have to make? And what parts should I replace? This will be my first engine swap, by the way.
