7m swap

Hi! I was planning on swapping a 7mgte into my mk2 but winters approaching and still havent found anyone in my local area with one however I do have a bottom end to a 7mgte. Has someone ever done a swap like this before? If so any troubles? and do I need a 7mgte ecu? and other stuff Id need to swap?

So short story of my car i bought it when i was 17 painted it for my senior project in high school and i blew the motor a month after i finished painting it :( so I decided to go big power with an NA 5m build haha then i really thought about that and decided 5m wasnt going to go much of...
