Question 3rd gen engine swap

Hey I found a 2nd gen with a bad engine for cheap. the engine runs but it has coolant in the oil and other way around. How Hard would it be to swap out the engine for a 13b-rew. i know the ecu has to go but will i need to change motor mounts anything like that. what are the biggest problems with the conversion. if some one can help me with these questions that would be great. thanks
