Description

The IAG 550 Short Block is designed for modified EJ25 Subarus that need a stronger short block to support increased cylinder pressures created by additional boost pressure. The IAG 550 short block features IAG Spec H-Beam forged connecting rods. The upgraded connecting rods and race bearings are able to support additional engine load produced by larger turbochargers or increased boost which the OEM STI rods found in the Stock short blocks cannot support reliably.
