automatic engine swap?

hello guys, ok, would it be possible to swap engines on a 90' honda civic dx hatch with another civic or even another integra engine, swapping automatic for a more powerful automatic engine? i know that standard is way better, but if its possible to do, i would wanna do this to my car? and if this is in anyway possible, what engines would be best to upgrade with?thanks guys for taking the time to read and comment.

Yes its possible you just have to get another auto tranny that will fit to the motor you want to swap in.

ok, so it is possible, but what would be a good engine to upgrade to?( something obviously better than the dx engine)
