IAG Performance IAG-ENG-S600 IAG 600 FA20 DIT Subaru Short Block for 2015-21 WRX - 600 BHP

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. Each IAG 600 Short Block starts with brand new FA20 DIT Subaru 2.0L, 86mm stock bore engine case halves as standard. The case haves are carefully bored and honed to 86.25mm then measured and assembled using a new 2015+ Subaru 2.0L FA20 crankshaft, which is matched to ACL or King race main bearings. The IAG 600 Short Block features IAG Spec H-Beam Connecting Rods with ARP2000 rod bolts, along with ACL or King race rod bearings. The case halves are sealed with new OEM main case bolts and sealant. Finally, IAG Spec JE FSR 86.1mm Forged Pistons are carefully selected, measured, and installed to finish off the short block.
