Description

Stealth Mach 2 67 VGT - L5P is an easy to install 800 rear wheel horsepower capable upgrade that lights quickly, controls EGT's under heavy load, allows to turbine braking during towing, 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 then this is the turbo for you!

Package includes:

  • 800+ RWHP verified in competition applications with extensive supporting mods
  • 650 RWHP capable with emissions compliant tuning and basic supporting mods
  • Fits 2017-2022 Duramax L5P. Also compatible with 2019+ L5D.
  • 100% Stock Appearing Drop-In
    • Completely bolt-on (fits just like your factory turbocharger)
  • High Flow Vane Technology - Calibrated Power Solutions' Proprietary Custom Nozzle Ring Assembly (Vane Cage and Vanes) create the fastest spooling and highest flowing drop-in style variable geometry turbocharger available
    • Low drive pressures at high load
    • Improved efficiencies vs. stock to help with better EGT control
  • 10 Blade Turbine Wheel - produces distinctive throaty howl exhaust sound
  • Custom Billet 67mm Compressor Wheel - 11-blade design provides a wide efficiency range allowing users to tow without risk of surge
  • 81 lbs/min of Air Flow vs 60 lbs/min stock
  • New Assembly - NO CORE CHARGE
  • Fully Functional Exhaust Brake
  • Quick Spool-Up = Useable Horsepower
  • Wide Torque Curve
  • Fun to Drive - maximizes the L5P's top end performance and can still tow capably when called upon
  • 12 month Warranty

The L5P Stealth Mach 2 67 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. Stealth turbos featuring Calibrated's HFV upgrade are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.

Your truck is going to experience increased performance across a wide operating range due to Calibrated's proprietary HFV assembly, oversized turbine wheel, and billet compressor wheel. Built from brand new parts, this turbocharger won’t require a core charge. The optional actuator is pre-calibrated and the entire turbo comes ready for installation.

This Turbo is Designed for you if you...

  • Already have, or are also installing custom tuning
  • Daily drive your truck
  • Have Reliability and Performance as top priorities
  • Tow with your truck
  • Want More Power when you need it, but still have excellent street manners!

Do you need an Actuator?

If you're wondering whether or not you should buy an actuator to compliment your Stealth turbo, allow us to share our thoughts.  The L5P actuator has a very low failure rate in the field.  The fact that it's well-cooled and not in close proximity to the hot parts of the turbo means that it's out of harm's way.  Unless you're experiencing codes that indicate actuator issues or know for a fact that your actuator is somehow damaged, we would suggest saving your money and retaining your factory actuator.

NOTE: You should strongly consider custom tuning to go with this turbocharger upgrade. We have made up to 650 RWHP when matching this turbo with Emissions Compliant Tuning.
