Hey my name is nick and im only 15.. im trying to get started out into the driving world

. And im really interested into getting a older corrolla ae86 :P.. and im trying to research on it it,, wether i should get the corolla or the old FC rx-7, but i heard they engines on the rx-7's are just a big pain in the ass :'(. I also luv how the ae86 looks ..
so i got a couple of stupid questions but hopefully you can answer them if you can!
-What are all the engines that will fit in the ae86?
- What years run for the ae86 chassis or w.e?
- Is the engine swapping hard to do in a ae86?
-Is it low costing to maintain and upgrade a ae86 ??
well thats all i can think of right now its 3:11am where i am at right now so if these questions are weird, or just stupid, or make no sense.. im sorry
