will be geting a 2.0 focus engine soon so do my swap.

it will be replaceing my 1.8 from my 3rd 1999 focus and i have been told its a straight swap and will just need a re-map and away to go.

but i need to know if thats true and is there anything at all i need to know or to look for or to make sure of on the 2.0 before i go geting it?

like code numbers

any help or advice would be great.
