So it already has 50k miles on it then? If so it's more than completely broken in.

Which year is the motor from?

Break-in only applies to new / rebuilt engines. A motor with 50k on it is neither. You should be good to go (after a fresh oil change, plugs, etc.). Any Subaru engine could either last a) 150k-200k miles or b) blow up a week after the install. It depends on prior tune / boost levels experienced, and how the engine was treated. Get a compression test done.

hopefully you live in an area without emissions.

you'll NEED to have a tune for it ASAP. they are designed to run on higher octane gas than what we get in the states.
