Stage

Our deck closing service involves machining the top plane of the engine case (the head plane) to accept CNC-machined inserts. This process fully supports the cylinder walls at their weakest point—the top, where combustion occurs—ensuring they withstand the intense pressure when the engine is running. Additionally, all coolant bores present in the head gasket are precisely machined into the cylinder-supporting inserts, ensuring the engine's cooling efficiency remains unaffected.

For enhanced performance, stages 2 and 3 include an extra cooling passage machined under the head gasket, allowing engine coolant to flow more freely.

Available for All EJ20, EJ22, and EJ25 Engines

We offer three stages of deck closing, tailored to different performance needs:

  • Stage 1: 10mm thick inserts, suitable for all EJ cases, supporting up to 550hp.
  • Stage 2: 15mm thick inserts, suitable for all EJ cases, supporting up to 750hp.
  • Stage 3: 25mm thick middle two inserts + 15mm outer inserts, designed for maximum performance in all high-horsepower applications.

Enhance the durability and performance of your engine with our expert deck closing services. Contact us to learn more and discuss which stage is right for your needs.
