Description

The IAG Performance Stage 2.5 International Hybrid EJ25 Subaru Closed Deck Short Block is a performance engine component designed to increase displacement and low-end torque. It is engineered to match EJ20 cylinder heads without requiring modification to the cylinder head chambers. This short block is built using brand new Subaru 2.5L engine case halves that are CNC machined and converted to a closed deck configuration with IAG's proprietary inserts.
