86 Sentra Engine Swap

[bug213]

New member and first post to this forum, as this is my first Nissan car project.
I've got an old FWD 1986 Sentra that has been pretty well trashed and the engine is completely gone. I'm going to be rebuilding it soon as a new project. The idea is to turn it into a sleeper / street car.
The main issue right now is finding the engine to bring it back to life, which will hopefully be a sr20det. Has anyone ever swapped an sr20det into an old Sentra like that? What would it take to put an sr20det into it? I've found the complete engine and trans with everything needed with it. But as far as the motor mounts and alignment and such I'm not sure what it would take. Would there be a better recommended motor for this build?
Any info or links as to what would have to be done would be greatly helpful.
