High-Response HX25W Turbocharger for PC128/PC130/PC160 Excavators

• Precision 4-Cylinder Optimization: Specifically engineered for the SAA4D102E and SAA4D95LE 4-cylinder engine platforms. Restores original factory boost response and fuel efficiency essential for the agility and digging power of mid-size excavators.
• Direct "Drop-In" Fit: A 1:1 mechanical match for original Holset HX25W units. Fully compatible with factory air intake manifolds, oil feed lines, and exhaust flanges—ensuring a seamless, zero-modification installation for site mechanics.
• K18 Nickel-Alloy Turbine Wheel: Features a premium K18 Nickel-Alloy turbine wheel, designed to withstand sustained high thermal loads (up to 950°C) common in high-frequency load switching environments without blade deformation.
• VSR Precision Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational RPMs (180,000+). Technical Benefit: This eliminates shaft vibration, ensures whisper-quiet operation, and maximizes the bearing service life in dusty environments.
• Heavy-Duty Wastegate System: Equipped with a pre-calibrated wastegate actuator to prevent over-boost conditions, providing reliable engine protection and a stable torque curve during heavy excavation.

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.
