04.5-07 5.9L Cummins Stealth Series 67G2 Turbo

The 3rd Gen Stealth 67G2 is an upgraded, drop-in, replacement turbo for 2004.5-2007, 5.9L Cummins.  It is designed to bolt in and requires nothing other than removing the factory turbo and dropping this one in it’s place.  The turbo features a custom profile, 67mm (actual measurement 66.5mm) billet wheel perfectly mapped to a modified compressor cover and 14% larger, 10-blade turbine inside the HE351's 9cm housing.  

The 3rd Gen Stealth 67 is one of the quickest spooling turbos we have tested for the 5.9L Cummins.  Even the most experienced enthusiast has a hard time telling the difference between a stock HE351 and a Stealth 67 during light throttle, daily driving.  This is directly tied to the tight exhaust housing and lightweight turbine wheel.  If you are going to daily drive your Cummins, consider a quick spool-up a "must-have". 

Stock injector / built transmission trucks can expect an easy 100+ RWHP (Rear Wheel Horse Power) gain with no tune adjustment required. 

3rd Gen Stealth 67G2

This charger is the perfect fit for those of you with future plans for a twin kit.  Take your time and put the build together in stages.  Start by upgrading the factory charger with an easy drop-in and build off it down the road.  In a compound or twin kit, we have many customers making 950-1,000 HP!  Of course, those builds include a more extensive list of supporting modifications.  Still, it is nice to know there is a proven formula to follow.  

On the other hand, if you want street-able power out of a single turbo, we have tested that too.  When really pushed, this turbo is capable of over 800 RWHP!  Calibrated Power tested 100% over Exergy Injectors with a 12mm Exergy Cp3 pump on a 2006 Cummins while sporting the 3rd Gen Stealth 67.  The truck made over 800 RWHP and took over (6) 1st Place Wins in the local Stock Appearing sled pull class.

Add on a Stealth Boost Tester.

Boost leaks can kill diesel engines. They cause higher EGTs, decrease your power, and lower fuel economy. Properly being able to test your entire charged air system is essential to getting peak performance and longevity out of your diesel engine. Charged air systems include everywhere from the turbocharger to the intake manifold. Your intercooler system, Exhaust Gas Recirculation components, and even the Turbocharger compressor cover can all develop boost leaks. This boost tester is exactly what you need if you work on diesel trucks regularly or just want to check the condition of your engine's charge system. Here's what you can get:
