I think a Turbo or any thing would be a dumb idea if the guy is not a car freak. If he just wants a fast car have him drive his car around as is but with the JLT Intake Upgrade, Pulley and Tune.
I however would really thing about keeping it all most stock. Minor mods for him because that is a car that you would want to keep your warranty on if any thing happens. Its easy to pull an intake and replace your computer back to stock but to take a turbo off and convert it back to stock is impossible. There will be fab marks showing that you altered some thing on the car.
Have him upgrade the suspension and just bolt on's I am sure he will be more then happy with that.
