Throw the horsepower idea out the window. Your engine will not rev that high. TQ is what you will increase. Expect 5-10% increase in TQ for each LB of boost. As an example of what these look like and availability, here is a turbo setup from a pontiac trans am 301 circa 80-81. Picked it up at a swapmeet this weekend for 80.00 as you see it. Also saw a buick one for 295.00 . So they are out there.
