Ok so I don't know a lot about Subarus hence why I'm asking. So back in October I blew the motor. It's a 2.5L EJ255 with 91k miles. It got what I thought was rod knock and just gradually started losing power, before it just stopped. The weird part was that it could idle for a while. Anyways, I have been in contact with a few places and they suggested I should swap the engine to either a used EJ20Y or EJ205. So if I'm going to swap these to one of these what specifically must be done to put it in. Also, is there any other suggestions about what to do? Thanks!
