Momentum Worx 80MM Billet | Cummins N14 Turbo Upgrade | MMWX.N14UGX

Take the Momentum Worx Cummins N14 Turbo Upgrade one step further with the MMWX.N14UGX, featuring an even larger 80MM billet compressor wheel while maintaining the factory-style turbo location and connections.

The Cummins N14 uses a unique reverse-flow turbocharger configuration that makes installing a conventional aftermarket turbo difficult without changing the exhaust manifold and associated plumbing. This turbocharger was designed specifically around the factory N14 layout, providing increased turbocharger capability without requiring a complete manifold conversion.

Compared to our standard 76MM N14 Turbo Upgrade (MMWX.N14UG), the N14UGX increases compressor inducer size to 80MM, providing an option for higher-performance N14 builds requiring additional compressor airflow.

Each MMWX.N14UGX turbocharger is assembled and balanced in the USA.
