Description

The L5P Stealth 67G2 emerges as the ultimate drop-in turbo for the 2020, 2021, 2022, and 2023 6.6L L5P Duramax. With the capability to provide sufficient airflow to support up to 800 RWHP, this stock-like unit ignites swiftly and excels in daily driving, towing, and achieving peak performance.

Incorporating HFV technology, this turbocharger represents our proprietary customization of the variable vane cage and nozzle ring assembly. This innovation enables the utilization of a larger turbine wheel for maximum high-load efficiency. Stealth turbos equipped with our HFV upgrade outperform those limited by factory nozzle rings, delivering increased power, quicker spool-up times, and superior management of exhaust gas temperatures (EGTs).

Your truck is poised to experience heightened performance across a wide operating range, thanks to our HFV assembly, oversized turbine wheel, and billet compressor wheel. Crafted from brand new components, this turbocharger eliminates the need for a core charge. The optional pre-calibrated actuator simplifies installation, making the entire process hassle-free. Custom tuning is essential to optimize the performance of this turbocharger on your truck, along with specific min/max vane positions (refer to the bottom of this page). Deletes are not required. With our Custom Emissions Equipped Tuning, we’ve achieved up to 650 RWHP when pairing this turbo with our custom tuning solutions.

Notes:

This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost which may shorten the life of the turbo or engine and may void the turbo warranty.
