IAG 1150 2.5L Subaru Closed Deck Short Block For WRX STI LGT FXT - 1150 BHP

The IAG 1150 Short Block is designed for those who plan to drag race their high horsepower Subarus regularly. While still a streetable block, the IAG 1150 is designed for the track. This block includes additional features to further strengthen the OEM case halves including Stage 4 Closed Decking and pinned mains secured with ARP case hardware. Our record-setting "Fire-Lock" Head Gasket system and 14mm head studs are used to ensure a tight seal even in extreme conditions. The IAG 1150 Short Block features IAG Spec "Tri-Beam" +2mm forged connecting rods. An IAG Spec Billet Crankshaft is used to support additional oiling and prevent main bearing distortion. The upgraded block, billet crank, connecting rods, race bearings, and forged pistons are able to support additional engine load produced by the largest turbochargers and the most demanding uses including competition drag racing. Every IAG Short Block is built with 100% new components. The modified case halves are assembled using an IAG-Spec Billet crankshaft that is matched to ACL or King race main bearings. Custom IAG TRI-BEAM +2mm connecting rods with ARP 625+ rod bolts are utilized, along with ACL or King race rod bearings. The case halves are sealed with OEM sealant and ARP main bolts. The IAG-Spec 99.75mm Custom Forged Pistons with .250" / .927" wrist pins as well as electroless nickel plated tops and ring area are chosen to finish the IAG 1150 Short Block.
