High-Performance GT4082KLNV VNT Turbocharger for 338, FD, FE, SG Series

• Variable Nozzle Turbine (VNT) Precision: This GT4082KLNV unit features an advanced Variable Nozzle system designed to synchronize perfectly with electronic engine control unit (ECU). By adjusting the internal vane angles, it provides optimized boost across the entire RPM range, significantly reducing turbo lag and providing the high-torque response required for medium-duty vocational trucks.
• Severe-Duty Thermal Stability: Engineered for the intense heat cycles of the J08E engine, the turbine housing is cast from high-nickel ductile iron. This metallurgy is essential for resisting thermal fatigue and the "vane sticking" issues common in VNT turbos, ensuring reliable engine braking and boost control during mountain climbs or heavy-load hauling.
• Precision VSR Dynamic Balancing: To ensure maximum bearing life and prevent cabin noise, every core assembly (CHRA) is balanced on a high-speed Vibration Sorting Rig (VSR) at speeds exceeding 100,000 RPM. This eliminates microscopic shaft oscillations that cause premature journal bearing wear and the high-pitched "VGT whistle" often heard in budget-grade units.
• Emission & Torque Map Compatibility: This turbocharger is precision-calibrated to match the factory J08E fuel and torque maps. It ensures full compliance with heavy-duty emission standards while maximizing fuel economy during highway cruising, providing the sustained power needed for Class 6 and 7 truck operations.
• True "Plug-and-Play" Installation: This is a precision 1:1 replacement for original factory units. All mounting flanges, oil inlet/drain ports, and coolant connections are machined to exact 726997-5013S and 24100-4320 specifications, ensuring a seamless installation without manifold or harness modifications.

Fengcheng Zhongke Turbocharger Co., Ltd. is a leading high-tech factory specializing in the R&D, production, and global distribution of high-performance turbochargers. Based in Fengcheng—one of the world’s most renowned turbocharger manufacturing hubs—we have grown from a local workshop into a global supplier, serving heavy-duty, commercial, and passenger vehicle markets worldwide.

At Zhongke, we don't just "make" parts.we engineer reliability.

• Material Integrity: We exclusively use K18 Nickel-Alloy turbine wheels, capable of withstanding extreme exhaust temperatures (up to 950°C) without deformation.
• Dynamic Balancing: 100% of our turbochargers undergo high-speed dynamic balancing tests at 150,000+ RPM to guarantee zero vibration and extended bearing life.
• Certified Quality: Our production processes are certified under ISO 9001 and IATF 16949, the gold standards for the global automotive and heavy-machinery industries.

Manufacturing Prowess:Our facility is equipped with state-of-the-art production lines, including precision 5-Axis CNC machining centers, high-speed VSR (Vibration Sorting Rig) balancing machines, and advanced material testing labs.

Our Specialization:We maintain a vast inventory of over 3,500+ turbocharger models, with a focus on heavy-duty and construction machinery engines. Focused on optimizing fuel efficiency and restoring factory horsepower, our passenger car turbos are engineered with the same precision and K18 heat-resistant materials as our industrial line, ensuring reliable performance for daily commuting and high-speed driving alike.
