The turbo placement on 2003+ Cummins does not lend itself to equal cylinder distribution due to being centered on the number four and five cylinders, as opposed to centered on the engine on three and four.
For stock, or only slightly modified engines, this is not a critical flaw, but as horsepower and boost numbers increase, it becomes more imperative to properly displace airflow equally across the cylinders. This turbo installation kit from BD allows you to do just that by converting to a 2nd Gen style manifold (found on 98.5-02 Cummins with a centered design) and all of the accompanying hardware necessary to move your S400 turbo of choice into this more desired, centered location.
All you need is to mate this kit with the S400 turbo of your choice to properly match your fueling and truck use and you're set!
Note: Low A/R combinations must be wastegated to prevent turbocharger over speed conditions.
Wastegate Valve Regulator Kit - If you're running an external wastegate, such as the popular Turbo Smart HyperGate, this regulator kit will further allow you to fine tune your drive pressure for optimum performance. In most situations, if both ports are left open on the wastegate, it will open at 63 psi of drive pressure. By installing this regulator, you can regulate your pressure above this for maximum control.
TurboSmart WG45 Hypergate - By far, the most widely known name in the wastegate industry is TurboSmart, and for good reason. For years, they have been building the most reliable mechanical wastegates to consistently control boost levels. The Hypergate 45 is ideal for this particular turbo setup and to ultimately avoid possible over speed conditions.
