4g63 Motor Swap

i was wondering how hard it would be to drop a 4g63 in place of my 420a in my 95 eclipse gs im buying a crate motor and was thinking of mabe just getting a 4g63 instead of another 420a but would it work?

PLEASE use the search button. Hearing this question gets really old. It can be done but not without some serious $$$$$. You would be able to get like 3 eclipses with the money it would cost you.
