Description

The L5P Stealth 64 stands out as the ultimate drop-in turbo engineered for the 6.6L L5P / L5D Duramax engines of the 2020 to 2023 models. With the capability to support up to 700 RWHP, this turbo combines remarkable airflow with swift responsiveness, making it ideal for daily driving, towing, and asserting dominance over Powerstrokes.

At the heart of this turbocharger lies HFV technology, a proprietary enhancement of the variable vane cage and nozzle ring assembly. This innovation allows for the utilization of a larger turbine wheel, optimizing high-load efficiency. Stealth turbos equipped with our HFV upgrade deliver increased power, faster spooling, and superior EGT management compared to those constrained by factory nozzle rings.

Expect heightened performance across a broad range of operating conditions, thanks to our HFV assembly, oversized turbine wheel, and billet compressor wheel. Crafted from entirely new components, this turbocharger eliminates the need for a core charge. The optional pre-calibrated actuator simplifies installation, making the entire setup ready to go out of the box. Considering custom tuning alongside this turbocharger upgrade is strongly advised, although deletes are not necessary. Pairing this turbo with our Custom Emissions Equipped Tuning has yielded impressive results, with gains of up to 650 RWHP achievable.

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.
