i don't see why you'll swap 5sfe in there??
easy swaps: -Paseo 5efe engine
-JDM 5efhe engine
-or starlet jdm 4efte turbo engine. Those will drop in on the stock mounts all you need is wiring
If you want to deal with making new mounts and all the custom stuff:
-4age--any
-or 3sgte
and whatever other frankenstein you have in mind
