I am happy with my Pro-Charger, would definatly go this route again on another truck. I personally don't like the oil and heat issues with turbo's. I've put them on snowmobiles (Yamaha 4-strokes) incredible gains, just issues with heat like I had one turbo that glowed red after a couple of hard runs. That's with lots of oil pressure. I know it's way different on a truck with larger oil resivoirs and and intercoolers, we were also seeing 350hp at the crank with a 1000cc engine! Do most of the turbo kits require a header change? or are they tapping in further down the line?

 

On the Modulars you can flip the factory manifolds and work from there. They'll work just as well as any log-style manifold and they don't cost anything extra.
