Building this line of Stealth's meant designing a turbo that would be safe to tow with, fun to drive every day and perform at competitions. If you think street-able, clean, stock-appearing power is cool than this is the turbo for you! The Duramax Tuner Stealth 67 G2 Drop-In Turbocharger provides you with a direct replacement, bolt-on, stock appearing turbocharger for your 2001-2004 GM 6.6L Duramax LB7 that will support up to 800HP. Turbocharger technology is quickly evolving at Duramax Tuner giving you features you won't find anywhere else. The G2 improves power, towing potential and overall performance through the use of a custom designed high flow turbine assembly and 7075 billet compressor wheel. This is all done in a liquid cooled package protected by 360 degree thrust bearings.
The custom 67.7mm compressor is milled out of high strength 7075 Aluminum, designed is specifically to maximize peak power. To fit that wheel Duramaxtuner developed a unique, OEM appearing, anti-surge ring that's sleeved into the factory IHI compressor cover. Redesigning the compressor to maximize power and drivability meant pouring over every detail of from MWE groove width and placement to diffuser clearance and shape.
