Calibrated Power Stealth 64G2 Drop-In Turbo, 2001-2004 GM 6.6L LB7

The LB7 Stealth 64G2 Turbo is a direct drop-in, bolt-on stock appearing replacement but with features you won’t find anywhere else. The LB7 Stealth 64G2 improves power, towing potential and overall performance through the use of a custom-designed high flow turbine assembly and 7075 billet compressor wheel. We do all this in a liquid-cooled package protected by 360-degree thrust bearings.

The larger turbine assembly allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load means more efficiency and power at a given boost number, resulting in lower EGTs under heavy load. Overall peak power is also improved, the LB7 Stealth 64G2 pushes the envelope to 640HP. You’re not going to find all of these features anywhere else in the aftermarket in a truly stock appearing, bolt-in IHI-style turbocharger.
