What kind of problems would I run into if I go turbo?
If you offroad, there are multiple problems that have been witnessed by people who have tried to create a twin turbo system. I seem to remember a transmission or fuel line coming loose offroading and starting a small fire that was quickly put out. Then comes the question of where do you mount everything and how. Mounting things off the engine probably isn't a good long term solution with how hard these trucks are run offroad. Then, on top of all of that, you have the tuning issue. From what I remember from the Twin Turbo thread that was on FRF (I don't know if it was deleted or not, I didn't search), trying to get the tune dialed in and perfect was a gigantic pain in the ass. Then you have the massive amount of heat the turbos will put off and how you will get rid of that heat so you don't melt things under the hood. And then on top of all of that you have the potential 6 rib belt problem.
Anything is possible with money, but sometimes it's just easier to go with a tried and true Whipple/Roush blower.
