*MOMENTUM WORX | Cummins ISX Turbo Conversion Kit


 Product Description

From the factory, ISX engines utilize a VGT (Variable Geometry Turbocharger).  The electronic actuator moves an externally mounted arm that can open and close the vanes in the turbine housing, thus varying the A/R size of the housing.  While this feature is great when working correcrtly, it often fails, rendering the truck inoperable. While replacement VGT turbos are available, they have become extremely costly to repair/replace.  An alternative to this VGT turbo is to utilize a fixed geometry turbocharger.   A fixed geometry turbocharger is a turbo that remains at the same constant A/R, in other words - its a regular old turbo!

This kit allows your to install a standard (fixed geometry) turbo on your ISX.   *REQUIRES ECU RE-CALIBRATION*  If installing on a stock truck, you will also need to use adapters or other modification to attach the exhaust, air filter system, and charge air cooler pipe.  We do offer exhaust adapters, see options below.
