Description

The IAG 600 Short Block is designed for stock or modified FA20 DIT Subaru WRXs that need a stronger bottom end to support increased cylinder pressures created by additional boost pressure. The IAG 600 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 rods and pistons found in the stock short blocks cannot support reliably.
