Mitsubishi Evo X Closed Decking Service

Our Closed Decking service for Mitsubishi Evo X engines is designed to fortify the cylinder walls of the 4B11 and 4B11T engine blocks, ensuring superior durability and resistance to the intense pressures generated during high-performance use. This service is especially crucial for those pushing their engines to the limits, whether on the track or street.

Service Highlights:

• Enhanced Cylinder Support: We machine the top plane of the engine case to accommodate precision CNC machined inserts. These inserts provide critical support to the cylinder walls, particularly at the top where combustion forces are strongest, significantly reducing the risk of wall flex and cracking.
• Maintained Cooling Efficiency: Our process ensures that all existing coolant bores in the head gasket are incorporated into the supporting inserts, maintaining optimal engine cooling. For further enhancement, an extra cooling passage can be machined, allowing for improved coolant flow under the head gasket.
• Compatibility: This service is specifically tailored for Mitsubishi 4B11 and 4B11T engine blocks, making it an ideal upgrade for Evo X owners seeking to boost engine reliability under high boost pressures.

Comprehensive Service Offering:

We offer a complete service package that includes the pickup and re-delivery of your engine case after all engineering processes are completed. Your engine case will be meticulously prepared, ready for you to start the assembly process, or you can entrust it to our expert engine builders for a professional finish.
