swap for at. engine.

hey guys, i have a 90 civic hatch, it's an auto, yeah i know it aint fast but i love my car, n-e-ways i was wondering if is was possible to swap out the engine for another one, for example from a 92-95 civic ex, something with a lil' more power of course. and i don't want to switch from auto to stick either, keep it auto. would that be the only choice i would have to choose from?
any links would be helpful aswell.

d16z6 engine what you are asking it is pretty much 100% swap but will have to wire up vtec which isnt hard to do. but more power with a auto is pretty much not noticable lol...but i leave that up to you hehe
