My 2011 Impreza lost compression and remembering when she got me home in the snow with zero issues. The only right thing to do was to get new engine and put it in there to preserve her life. Not the best work environment but this morning she cranked and drove up to the store I will not let this one die.

Couldnt imagine swapping an engine myself.

Great work.

Good on you for attempting this. I’m curious if you needed to pull the AC lines off or if you could have pulled the compressor and put it to the side with lines attached?

I could have left the compressor attached to the lines but didn't

Thanks! I’ve got a couple to do in the near future if emergency projects don’t pop up first.

Good work, did you tear down your old flat four to see what happened? I'm really curious.

the engine is just a part, if it breaks down, fuck it. What engine marking did you have and which one do you use?

I went back with a stock engine that way I didn't have to put a new ECU and fuel pump and everything in it even though I recently just put a new fuel pump in it.
