new parts

Hey whats up I am looking to upgrade my 4 banger to either turbo or super charged. I do not know much about car but i am looking to spend around 5-10 grand on just the engine. no NOS just straight motor. I just need to know where to start, what i should buy first and so on. Just looking for input. I am also thinking of convertint my car to rear wheel drive how many people out there think i should do that. which one gives out more horses. Also looking to buy a motor if you have any suggestions on what to buy let me know. anyone who knows any good info please let me know. remember i don't know crap about cars so please put your replies in lamens terms. I am thinking along the line of a AE101 4A-GZE motor with a supra transmission. What kind of suspension, etc... to beef up the rear end before I make it rear wheel drive.
