Description

The IAG Stage 1 Short Block is perfect for lightly modified EJ25 Subaru’s that need a basic and reliable performance short block. Subaru turbo engines are commonly known for piston ring land failures and if gone unchecked lead to rod knock and total engine failure due to oil starvation from blow by. IAG’s Stage 1 Short Block includes upgraded forged pistons along with performance main and rod bearings that replace the OEM components that are prone to common failure on Stage 2 and up vehicles. Each IAG Stage 1 Short Block starts with a new Subaru 2.5L 99.5mm bore EJ25 engine case halves as standard. The short block is measured and assembled using a new 2017 Nitride Treated Subaru 2.5L STI crankshaft that is matched to ACL or King main bearings. Early style OEM STI rods are utilized along with ACL or King rod bearings. The case halves are sealed with new OEM case bolts and sealant. Finally 99.5mm IAG-Spec JE Forged Pistons are spec’d and installed finishing off the short block.
