2000 eclipse gs

I have a 2000 eclipse gs with non turbo 2.4.
Wanted to know what all would I need to put a
turbo in it. I got the car for $300. Nothing wrong
with it except it lags in second gear ( manual
tranny). I was told by numerous people that it was
a timing problem. I know the kid that had it. He
only drove to work and home and his work isn't
even a mile away from his house. It never
overheated or anyrhing. When this started
happening he parked it and it has sat since. Want
to know what I would have to do to the engine to
put a turbo in it. And where can I get the parts at
that won't cost me a arm and a leg. Your help is
greatly appreciated. Thank you.
