    Don't listen to him...he's got a factory freak for a motor!! lol
    He also made over 700rwhp on a stock 4.8!!

    As far as cost, it will take quite a bit depending on which direction you go. Turbo cost will be somewhere in the $10-$15k range depending on how big you go and what kind of deals you can find.
