Hmmm. Anything is possible but for how long and how reliable. The basics would be to strengthen up the bottom in with some low compression pistons, stronger rods. Refresh the head and by all means make sure the fuel supply is adaquate and definitely have it tuned. PSI is relative because it changes with turbo. 8psi on a .40 trim vs. 8psi on a .70 trim turbo is different.
