*MOMENTUM WORX | Cummins ISX Turbo Conversion Kit


 Product Description

Tired of the problematic HE series turbochargers on your Cummins ISX CM870, CM871, CM2250/2350, X15 Engines?  Constantly having actuator fail or sticking?  Want to make real horsepower power gains while maximizing up time?  This is the turbo upgrade for you!

This kit allows your to install a BorgWarner Performance 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.
