Turbo six on a Budget

pay once, cry once,...do it right once or do it over, witch is cheaper in the long run???
i relisie this but me being 15 i am impatient and saving up the extra cash for the forged pistons and macine shop will take allmost a year with my cash flow. I am ok with turning down the boost and making less power too. My main goal is to make more power safely.
