High-Performance C9.3B Turbocharger for 336 & 345 GC Excavators

• Tier 4 Final / Stage V Optimization: This C9.3B turbocharger is precision-calibrated to synchronize with the advanced electronic fuel maps of Next-Gen engine platforms. It ensures consistent boost pressure required for Stage V emission compliance while maintaining the high-torque output needed for deep-trenching and heavy material handling.
• Severe-Duty Metallurgy: The turbine housing is cast from high-nickel ductile iron, engineered specifically to resist thermal fatigue and "heat checking" common in Tier 4 engines. This superior material prevents housing distortion and wastegate binding, even under the intense heat cycles of 24/7 quarry and construction operations.
• Precision VSR Dynamic Balancing: To guarantee a long service life and prevent machine downtime, every core assembly (CHRA) is balanced on a high-speed Vibration Sorting Rig (VSR) at speeds up to 150,000 RPM. This eliminates microscopic shaft oscillations that lead to premature journal bearing wear and the common high-pitched "turbo whine."
• Enhanced Hydraulic Response: The internal wheel aerodynamics are optimized for the airflow characteristics of the C9.3B 9.3L engine. This provides rapid spool-up at lower RPMs, ensuring the engine responds instantly to sudden hydraulic loads—critical for smooth, multi-function operation in the 336 and 345 GC series.
• True "Plug-and-Play" Installation: This is a precision 1:1 replacement for original factory units. All mounting flanges, oil inlet/drain ports, and electronic wastegate actuator mounting points are machined to exact 528-1450 and 575-9942 specifications, requiring no manifold or plumbing 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.
