High-Performance S2A Turbocharger for BF4M913 & BF4L914 Industrial Engines

• Precision Industrial Engineering: Specifically engineered for the 4.09L (BF4M913/BF4L914) platform. Technical Benefit: Optimized for high-torque industrial duty cycles, delivering up to 77kW of consistent power for excavators and power units.
• Direct "Drop-In" Compatibility: A 1:1 mechanical match for original BorgWarner/Schwitzer S2A units. Fully compatible with OE numbers 04232252 and 04233174—guaranteeing a seamless installation without any manifold or oil line modifications.
• Enhanced Thermal Stability: Constructed with high-grade ductile iron housing to resist cracking under the sustained thermal cycles typical of air-cooled engines. The K18 alloy turbine wheel ensures zero blade deformation at maximum RPM.
• VSR Precision Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational speeds. This eliminates micro-vibrations, ensuring ultra-quiet operation and extending the life of engine bearings and seals.
• Fleet-Ready Reliability: Manufactured to meet ISO 9001 standards by Zhongke Turbo, offering a cost-effective, high-uptime alternative to expensive dealership parts for aging agricultural and construction fleets.

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.
