IAG Stage 2 EJ257 2.5L Built Subaru Short Block

SKU: IAG-ENG-1202

The IAG Stage 2 Short Block is designed for modified EJ25 Subaru's that need a beefed-up performance short block. The IAG Stage 2 short block builds off the Stage 1's strengths by adding IAG Spec H-Beam forged connecting rods. The upgraded rods and bearings are able to support additional engine load produced by larger turbochargers that the OEM STI rods cannot support reliably. Each IAG Stage 2 Short Block starts with new Subaru 2.5L 99.5mm stock bore EJ25 engine case halves as standard. The short block is measured and assembled using a new 2017+ Subaru 2.5L nitride treated STI crankshaft that is matched to ACL or King race main bearings. IAG-Spec H-Beam rods and ARP2000 rod bolts are utilized 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 99.5mm Forged Pistons are spec'd and installed finishing off the short block.
