Hello.
The best way for you to get these answers is to research.
There are sooooo many things that come to mind when swapping an engine.
I drive a 91 na 5 speed.
I'm going to start looking for a 2jzge to rebuild to hook to the w58 tranny.
Shop around and research any and everything. Engine swaps are no joke.
