Description

The VVT Stealth 67G2 transforms a stock-appearing LLY/LBZ/LMM turbocharger into the ultimate drop-in solution for Duramax VVT engines. With this upgrade, your new turbo will exhibit rapid spool-up, enhanced responsiveness, and crucially, improved airflow into your engine. This translates to increased top-end power without compromising driveability.

Featuring HFV technology, our proprietary High Flow Vane customization of the variable vane cage and nozzle ring assembly, this turbocharger delivers unparalleled performance. The HFV upgrade allows for the utilization of a larger turbine wheel, maximizing high-load efficiency. Stealth turbos equipped with HFV technology produce more power, achieve quicker spool-up times, and manage exhaust gas temperatures (EGTs) better than those limited by factory nozzle rings.
