AE82 - Engine Swap

[finnsk3]

I got a AE82 CS-X sedan FWD auto with a 4AC.

I am considering doing an engine swap to a 4AGZE or a 4AGE and I was looking at this 1,

4AGZE : 1600cc 16 valve DOHC EFI Supercharged engine (developes 120 BHP) $995.

from http://www.ekw.com.au but I understand that I will have to get a motor to fit a FWD so it will have to be a south-west motor and I was wondering how hard it would be to put in and what else I would need and how much its gonna cost me and how many KW I should expect to get. I understand that I am not gonna be able to put a 20v silver top motor in it am I cuz there RWD. Also am I gonna be able to use my current Auto gear box? because I would rather use an Auto gear box because I dont have a manual licence and I find Autos better for drags and I draged my mates Carolla which is exactly the same exept its manual and its a CS but same motor and stuff and he had the launch on me but I passed him easy and with my auto it red lines before it changes gear when I got my foot down.
