Product Overview
High-Efficiency HX30 Turbocharger for S4D102 & 4BT Engines
- Precision 3.9L Optimization: Specifically engineered for the legendary 4-cylinder 4BT and S4D102 series engines. Restores factory boost maps and low-end torque essential for the hydraulic response and digging power of PC120/PC130 excavators.
- Direct "Drop-In" Replacement: A 1:1 mechanical match for original Holset HX30 units. Fully compatible with factory air intake manifolds, oil feed lines, and exhaust flanges—ensuring a seamless, zero-modification installation for fleet 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 4-cylinder industrial and generator applications without blade creep.
- Precision VSR Balancing: 100% dynamic balancing tested on a Vibration Sorting Rig (VSR) at full operational RPMs. Technical Benefit: This eliminates shaft vibration, ensures whisper-quiet operation, and maximizes the service life of your engine bearings.
- Industrial-Grade Durability: Manufactured to meet IATF 16949 standards by Zhongke Turbo, providing a high-reliability, cost-effective alternative to expensive original dealership parts while maintaining factory-grade uptime.

Q1: How do I verify fitment for my PC120-6?
Please check the nameplate on your old turbocharger for the part number 3539803 or the number 6732-81-8052. While the S4D102 engine is common, different equipment may use different exhaust housing angles. Our unit is a standard 1:1 match for the PC120/PC130 series.
Q2: Is the 4BT turbo identical to the S4D102 turbo?
Yes. S4D102 engines are based on the 4BT architecture. As long as the part numbers match (like 3539803), the turbo is fully interchangeable between both brands.
Q3: Does the turbocharger include the mounting gaskets?
Yes. This unit typically includes a premium industrial mounting gasket kit to ensure a perfect, leak-free seal for the oil and exhaust connections. We always recommend using new gaskets for every installation.
Q4: What maintenance is critical for 4-cylinder industrial turbos?
Lubrication and Air Filtration. Small turbos spin at very high RPMs. We strongly recommend replacing the Oil Feed Line and the Engine Oil/Filter during installation. Clean air and fresh oil are vital to prevent bearing wear and compressor wheel erosion.
Q5: Do you provide worldwide shipping?What is the delivery timeframe?
We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
