Momentum Worx | Cummins N14 Turbo Upgrade | MMWX.N14UG

The Cummins N14 Turbo Upgrade is a direct bolt-on upgrade for factory N14 engines, offering increased airflow and performance while maintaining the factory turbo location and connections.

The N14 uses a unique reverse-flow turbocharger configuration, which makes swapping to a conventional aftermarket turbo difficult without changing the manifold and associated plumbing. This turbo was designed specifically around the factory N14 layout, making it an excellent option for truck owners who want a meaningful turbo upgrade without completely reworking the turbo system.

This turbo can be used on a stock truck or paired with light fuel upgrades and tuning for additional performance. Each unit is assembled and balanced in the USA.
