2017-2023 L5P 65/66 Stage 2 Drop-In Turbocharger

🔥 2017–2023 L5P Duramax Drop-In Turbocharger – 65mm TiN 7 Blade • 66mm 10 Blade High Flow Vane Upgrade

Step up to the next level of performance with this high-flow drop-in turbocharger designed specifically for 2017–2023 GM 6.6L L5P Duramax trucks. Featuring a larger compressor wheel and an optimized VGT design, this turbo delivers increased airflow, greater horsepower capability, and outstanding durability while maintaining factory fitment and drivability.

At the heart of this upgrade is a 65mm high-flow 7 blade compressor wheel, finished with a TiN (Titanium Nitride) coating to increase wheel strength and reduce blade deflection under high boost conditions. The larger compressor provides significantly greater airflow than stock, making it an excellent choice for enthusiasts looking to maximize performance without sacrificing everyday usability.

Paired with a 66mm 10 blade turbine wheel and our high-flow vane system, this turbo improves exhaust flow, enhances VGT efficiency, and delivers excellent throttle response with reduced exhaust gas temperatures (EGTs). The result is a turbocharger capable of supporting substantially more power while retaining smooth drivability.

Whether your truck is built for towing, spirited street driving, or higher horsepower performance, this turbo provides the perfect balance of airflow, response, and reliability.

🔧 Key Features:

• 65mm 7 Blade High-Flow Compressor Wheel – Increased airflow and horsepower capability

• TiN Coated Compressor Wheel – Improved durability and reduced blade deflection under high boost

• 66mm 10 Blade Turbine Wheel – Enhanced exhaust flow and overall turbo efficiency

• High-Flow Vane Design – Optimized VGT operation for faster spool and improved boost control

• True Drop-In Replacement – Direct fit for 2017–2023 L5P Duramax

• Optional New Electronic Actuator Available – Ensures proper operation and simplifies installation

• Improved Throttle Response – Faster boost recovery and smoother power delivery

• Lower Exhaust Gas Temperatures (EGTs) – Increased thermal efficiency under load

• High-Performance Upgrade – Ideal for towing, street, and higher horsepower applications

⚙️ Performance & Applications:

• Designed for 2017–2023 6.6L L5P Duramax

• Excellent for daily driving, towing, street performance, and competition-oriented builds

• High-flow vane system improves VGT response, boost control, and overall efficiency

• Supports significantly increased horsepower with proper tuning and fueling upgrades

• Maintains excellent drivability while offering substantial airflow improvements over stock

⚠️ Fitment & Installation Notes:

• No gaskets are included with this turbocharger

• Reusing factory components or sourcing new gaskets is required for installation

• Optional new electronic actuator is available and recommended for optimal performance and reliability

• Customers running an aftermarket intake system may need to purchase the optional anti-surge ring. Some high-flow aftermarket intake kits can alter airflow characteristics entering the compressor, potentially increasing the likelihood of compressor surge during certain operating conditions. The anti-surge ring is designed to improve compressor stability and airflow management, helping maintain optimal performance and turbocharger longevity.

• Factory intake systems typically do not require the anti-surge ring.

💪 Why Upgrade?

• Larger 65mm TiN-coated compressor wheel delivers increased airflow and greater horsepower potential

• Improved vane design provides quicker response, better boost control, and increased efficiency

• Reduced EGTs and improved overall engine performance

• Direct bolt-in installation with no fabrication required

• Built to handle everything from heavy towing to aggressive street and performance use
