[want a supra]

I've got a 1984 SVO with lots of problems, the power steering pump is broke (the return line for the reservoir keeps blowin out) and I want to put a manual steering rack in... so what kind should I use and where can I get one. also keeping the same turning radius.
And for problem number two, when I give the car gas it stalls and wants to die for a second then revs normally and shoots white smoke and smells like gasoline.
