This Turbo Wakes Up Your L5P Duramax

If you're looking to turn your L5P Duramax into the truck it should have been from the factory, the Stealth 64 Turbocharger with Actuator is a serious upgrade worth considering. Built for daily drivers who want more power without losing drivability, this drop-in turbo delivers up to 650 rear-wheel horsepower when paired with custom tuning and a few supporting mods. It lights quick, pulls hard, and still lets you tow confidently without any fear of compressor surge. Whether you're hauling heavy or just enjoying a more responsive throttle around town, this setup gives you the best of both worlds. The upgraded billet compressor wheel and high-flow vane design help move a ton of air, which means more power and cooler exhaust temps, especially under load. One of the biggest perks is that it bolts right in with no core charge, no deletes required, and you can keep your emissions equipment. It's tuned for real-world use and built to handle it all without sacrificing reliability. This is a turbo made for guys who use their trucks hard but still want to enjoy the ride every time they hit the pedal.

Every Piece Of This Turbo Was Built With Purpose

The Stealth 64 was designed from the ground up to outperform the stock L5P turbo in every category that matters. It features a custom 64mm 11-blade billet compressor wheel that delivers 74 pounds per minute of airflow, up from the stock unit’s 60 pounds per minute. Paired with a larger custom turbine wheel and No Limit's exclusive High Flow Vane (HFV) technology, this setup dramatically improves spool-up, reduces drive pressure, and allows for better exhaust gas temperature control under heavy load. The vane and nozzle ring assembly was specifically designed to match the oversized turbine for high-load efficiency without compromising low-end response. It holds up under towing, lugging, and hard acceleration without the typical turbo surge you might expect from other high-output units. This turbo is built from 100% new components including the actuator and electronics, so there's no core charge or concern about reman parts. It's also tuner-friendly, meaning your custom tuner can easily dial it in, and DuramaxTuner is available to assist with settings if needed. This is not a repurposed stock turbo, it's purpose-built for performance, durability, and driveability.
