Purchasing and upgrade questions for a 1993-1996 supra non turbo

[slayer8925]

Hi, i am planning on purchasing a 93-96 supra non turbo in automatic transmission. (I am 17) I just had a few questions which is why i came here to ask people who are very experienced with these cars.*apologies for the very beginner questions i am quite new at purchasing cars and performance upgrades*

-what price range should i be looking at when looking at all of the sale ads (please mention if your prices are in US dollars, because i live in Canada)

-in the future i hope to buy a turbo, since this car is going to be one with an automatic transmission what would be the maximum horsepower i can achieve?

-what other upgrades would i need to acquire this sort of performance?

-how much control is lost considering it is an automatic transmission?

Additional advice as regards to purchasing a supra would be greatly appreciated, Thanks!
