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, then this is the turbo for you! We left no stone unturned when engineering the LB7 Stealth 67G2c.

Our custom-built 67mm compressor wheel is specifically designed to maximize peak power. To fit that wheel we developed a unique, OEM appearing, an anti-surge ring that fits into the 1-of-a-kind compressor cover. This compressor assembly also meant diving into the details of every other part of the turbo. The backing plate had to be superficially designed to work with our wheel and cover setup. The new center section is fitted with a 360-degree thrust bearing to increase reliability and prevent walk. Even a newly designed wastegate solution is incorporated to make sure you have the most amount of power possible while maintaining reliability.

Building the LB7 Stealth 67G2 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 67G2. Our custom profile on the compressor wheel matched to the custom turbine wheel means you get power and driveability.

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 67G2 features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive-pressure. Helping you achieve as close to a 1:1 ratio between drive and boost pressure. This not only helps make more power but also manages EGT's.
