Stealth 64 VGT - L5P is an easy to install 700 rear wheel horsepower capable 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 then this is the turbo for you!
This turbocharger features HFV technology! HFV or High Flow Vane technology is Calibrated's proprietary customization of the variable vane cage and nozzle ring assembly. This advancement allows the use of a larger turbine wheel for maximum high-load efficiency. 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.
This turbo is designed for you if you...
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.
