800HP, Drop-In, LB7 Stealth 67G2
Building this line of Stealth's meant designing a turbo that's safe to tow with, fun to drive every day and class-leading competitor. If you think street-able, clean, stealthy power is cool then this is the turbo for you! We left no stone un-turned when engineering the LB7 Stealth 67G2.
Our custom 67.7mm T compressor is milled out of high strength 7075 Aluminum. Its TCT design is specifically designed to maximize peak power. To fit that wheel we developed a unique, OEM appearing, anti-surge ring that's sleeved into the factory IHI compressor cover. Redesigning the compressor to maximize power and driveability meant pouring over every detail of from MWE groove width and placement to diffuser clearance and shape. We dyno'd different designs for a month prior to selecting our production specs.
The LB7 Stealth 67G2 center section is fitted with a 360-degree thrust bearing and features liquid cooling to increase reliability and minimize thrust wear during competition use.
The turbine side innovation rivals the compressor side. Our turbine dwarfs the factory turbine in every way. The turbine scroll allows much higher flow, accommodating the monster turbine wheel. The LB7 Stealth 67G2 features the largest turbine available in an IHI (stock LB7 turbo) frame. Increasing turbine size dramatically reduces drive pressure under heavy load helping you achieve nearly a 1:1 drive to boost ratio under most operating conditions. Controlling drive pressure helps make more power and significantly lowers EGT's.
