EJ25 Closed-Deck Short Block Engine

The IAG-ENG-1270 is a meticulously engineered Subaru EJ25 closed-deck short block, designed for enthusiasts seeking enhanced performance and reliability. This robust short block is constructed with IAG's precise specifications, featuring IAG-spec JE forged pistons and a closed-deck design that significantly strengthens the engine block against high-pressure environments. This short block is a direct replacement for Subaru EJ25 engines, commonly found in WRX, STI, Legacy GT, and Forester XT models. It is built to handle increased power output and demanding driving conditions, making it an ideal foundation for modified Subaru vehicles. Specific fitment notes indicate that EJ20 Subaru WRX engines will require EJ25 oil pans for compatibility. Additionally, an IAG oil pickup spacer (Part# IAG-ENG-2081SP) is required when using this short block with an IAG oil pickup. These components are essential for a proper and trouble-free installation, ensuring optimal performance and longevity of the engine assembly.
