NOOB Q's

[oneof81]

I currently own a '93 Turbo All-Trac that is highly modified. It's not the fastest one in the states, it's probably the second fastest because there is another one in Miami that runs 10's in the quarter mile. Mine runs in the 11's and has about 425 at the wheels @ 22psi. I am selling the car and thinking very strongly about buying a TT Supra. My questions are pertaining to the Supra. I just wanted to qualify my knowledge of turbo cars before asking. Are the oil seals really such a big problem that I have heard with this engine? If I should buy one that needs the seals replaced, what does it cost roughly to get this done, and, more importantly, should I think about a six speed, or an auto? I have heard that the autos stand up to high horsepower much better than the Gertrags, but again, I don't know how much false information I have been getting and how much is true. Should I try to buy a bone stock car, or one that has already dispatched the TT for a single turbo? If I buy a stock car, how far can you go with the stock turbos? Will they provide enough boost to make decent horsepower and how far can you push the horsepower with the stock injectors and stock ECU?
