---------------------------------------
Our custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel we've developed a unique, OEM-appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. We even updated the wastegate to make sure you have the most amount of power and the quickest spool-up.
With the all-new compressor side and center section put together a turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. Our monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure. This not only helps make more power but also manages EGTs under heavy load.
The unique advantage of having our tuning experts work on this turbocharger design can’t be understated. DuramaxTuner’s experience with the particulars of how the Duramax platform responds to tuning adjustments and airflow changes was a crucial component in building you the perfect turbo upgrade.
Building the LB7 Stealth Mach 2 (67) meant designing a turbo that's safe to tow reasonable loads with, fun to drive every day, and a class-leading competitor. If you think street-able, clean, stealthy power is cool then this is the turbo for you! We left no stone unturned when engineering the LB7 Stealth Mach 2 (67). Our custom profile on the compressor wheel matched to the custom turbine wheel means you get power and drivability.

Big horsepower and towable without surge sounds awesome!
I sure hope they come out with something like this for my LBZ

@kevinkalivoda3442 We've got an awesome 67mm turbo upgrade for the LBZ that offers almost all of the same upgrades. You can check it out here on our website: duramaxtuner.com/turbo-chargers/vvt-stealth-67g2-turbo.html

I just bought one of these!!! Along with my other fuel system upgrades (SAC100 injectors, Stroker CP3, Air Dog, and several other things) can hardly wait to get my truck back from the shop! Going to be a sleeper, I just wish Chevy built the long block stronger so I didn't have to de-tune my setup...
