From weekend warriors to serious diesel enthusiasts, this turbo has the versatility to handle just about anything you throw at it.

Every Detail Of This Turbo Was Engineered For Performance

The Stealth 67G2 isn’t just an upgraded stock turbo, it’s a completely re-engineered system built for maximum airflow and high-load efficiency. At the core is a 67mm billet 11-blade compressor wheel paired with an oversized turbine and custom vanes that push 81 lbs per minute of air, compared to the stock unit’s 60. High Flow Vane (HFV) Technology improves throttle response and spool-up time, especially when towing or accelerating under load. The taller and wider vane design matches the larger turbine, reducing drive pressure and improving exhaust gas control without giving up low-end drivability. This setup also keeps the factory exhaust brake fully functional, which is crucial for trucks that see regular towing. The 10-blade turbine delivers a more aggressive exhaust note that signals performance without going over the top. Built entirely from new parts, including pre-calibrated electronics, this turbo is plug-and-play and ready to be dialed in by your preferred custom tuner.
