Key Product Features

• 100% Brand New: Zero-mileage unit. Every component—including the compressor housing, turbine wheel, and high-performance actuator—is factory-new.
• Precision VSR Balancing: Each turbocharger is balanced at high speeds to ensure smooth operation and long-term durability under the intense heat cycles of a high-performance petrol engine.
• Heavy-Duty Bearing System: Equipped with an upgraded bearing design to withstand the rapid spool-up and high RPMs typical of the 2.3 MPS engine.
• Direct Bolt-On Fitment: Precisely manufactured to match all factory oil, coolant, and exhaust mounting points for a seamless installation.

Critical Installation Requirements

To protect your investment and ensure peak performance:

1. Oil Quality: The 2.3 DISI engine is highly sensitive to oil. Use only high-performance full-synthetic oil and a new OEM-quality filter.
2. Turbo Priming: Fill the oil inlet port with clean engine oil and manually rotate the compressor wheel multiple times before the first start to prevent bearing scoring.
3. PCV System Inspection: A clogged PCV valve is a common cause of oil smoke and seal failure in these turbos. It is strongly recommended to inspect or replace the PCV valve during installation.
4. Coolant System: Ensure the cooling system is properly bled. This turbo is water-cooled, and air pockets can lead to localized overheating and cracking.
