Technical Specifications & Cross-Reference

This unit replaces the IHI RHV4 series. Verify compatibility using the following identification numbers:

Key Product Features

• 100% Brand New: Zero-mileage assembly. Unlike remanufactured units, every component—including the variable geometry system, actuator, and turbine wheel—is factory-new.
• Precision VNT Calibration: The Variable Nozzle Turbine (VNT) mechanism is factory-calibrated on a flow bench to ensure exact boost delivery, preventing "limp mode" errors and ensuring fuel efficiency.
• VSR High-Speed Balancing: Each core is balanced at speeds exceeding 150,000 RPM to ensure vibration-free operation and maximum bearing longevity under high thermal stress.
• Direct Bolt-On Fit: Manufactured to exact OEM specifications for a seamless "Plug & Play" installation with original oil lines and exhaust connections.

Critical Installation Requirements

The Mazda RF7J engine requires specific care during installation to ensure turbocharger longevity:

1. Mandatory Oil & Filter Service: Change the engine oil and filter. Use only premium synthetic oil meeting ACEA C1/C2 (low SAPS) specifications to protect the DPF system.
2. Turbo Priming: Fill the oil inlet port with clean oil and manually rotate the compressor wheel multiple times before the first start to ensure the bearings are not dry.
3. Inspect Oil Feed Line: Check the oil supply pipe for carbon deposits. We strongly recommend replacing this line, as oil starvation is a common cause of failure for VJ36 units.
4. DPF Condition: Ensure the Diesel Particulate Filter (DPF) is not blocked. Excessive backpressure from a clogged DPF is a leading cause of turbocharger oil seal leaks.
