turbo help

Yeah you can take the wastegate hose off and put something in it to plug it, then it will never open the wastegate, though disabling the wastegate is highly unrecommended. If the turbo builds over 35psi, it loses efficiency and longevity. The stock turbos are not meant for over 35. A better route is a boost elbow. If you google "cummins boost elbow" you will see what I am talking about. These allow you to adjust your max boost so it doesn't end up flying over 35psi.If you were ever to get into 45+psi range on a stock truck, the head gasket would be under so much pressure that it wouldn't be able to hold. It would eventually give way and mix your coolant and oil and give you a wonderful mess to clean up.

To correct and add to ISX a blocked wastegate can lead to a turbo overspeed condition and that is where things get messy when the shafts break and send parts and oil to places they shouldn't be. That is the thing to worry about versus too much boost. The stock CR engines can handle boost more than the 24valves but it will send the egts through the roof and could lead to melted pistons cracked valves ect.
