Turbo's on a 5.0 ????
Hellion makes a turbo kit for the 5.0 cars, not sure if they've made a kit for our trucks though. If you're going to turbo our engines, I'd say build one to handle the power. Lol. These engines are strong for the most part, but boost will always find the weakest point eventually.
You could piece a kit together little by little. You'd have to find a tuner you trust to program everything though.
