Stealth 67 VGT - LML 800rwhp

The Stealth 67 VGT is an easy to install upgrade that spools up quickly, controls EGT's under heavy load, allows to turbine braking during towing scenarios, and kicks ass when leaned on. 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!

To compliment this turbo we highly recommend our High Flow Intake Bundle Kit to maximize performance, EGT control, and spool up.

This custom 67.7mm compressor is milled out of high strength 7075 Aluminum. It's TCT design is engineered to maximize peak power. To fit that wheel Calibrated developed a unique, OEM appearing, anti-surge equipped 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.

The LML 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 and the Garrett 4094VA in every way. The turbine inducer is taller, allowing much higher flowing vanes which are actuated with a matched unison ring. The LML Stealth 67G2 features the largest turbine and vanes available in this 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.

Purchased from: Wehrli Custom Fabrication - WCFab

I bought this turbo in junction with the high flow bundle kit and the 10mm CP3 conversion kit. This turbo has changed my entire trucks’s driving style. It drives great and is a beast of a turbo when used in any situation. I’ve owned this turbo for 6 months and I truly can’t get enough of hearing this thing whistle and spool. I’m only running a 45hp tune and my truck feels like it just wants be unleashed. This turbo is worth every penny and WCFab is truly a quality company.
