what can i do to restore my 91 240???

[qstudent819]

I've been having alot of overheating problems with my 240 and me being a dumb a*** i was stuck n a winter storm last winter and had to drive it up a hill. As i was diving up the hill(in 1st gear the whole time)my temp meter started to rise until at the top of the hill it went past hot and jus cut off on me. when i tried to start it up it would make this whining noise but then wouldnt make any noise.....About 2 months later my battery was dead so i charged it up and after i connected everything i tried to start it up. when i turned the ignition the engine fan started to move and made a sound as if it wanted to start it......i dunno what the hell is wrong with my car. what should i do to get my car running again????? I want to turbo the ka instead of getting a sr or ca but money isnt good with me right now at all. i wanted to know is it possible to do a rebuild on the engine??? how much would it cost me??? I jus want it running please help me and thanks in advance
