| Manufacturer's Description: Description: The IAG Performance Hand-Built Subaru EJ25 Closed Deck Long Block Engine Packages are a complete, valve cover to valve cover, crate engine. These engines offer significant ease of installation for customers seeking a complete "drop-in" engine package for their WRX, STI, Forester XT or Legacy GT. The Long Blocks feature a combination of our proven IAG Performance 1150 Closed Deck Short Block and IAG 1150 Cylinder Head packages, along with other race-proven components to complete the assembly. When paired with our Long Block Installation Packages, you have a true plug-and-play solution to get you back on the road, FAST! All components included are BRAND NEW and there is NEVER A CORE CHARGE required. The IAG 1150 package is ideal for clients looking for an engine package to support up to 1150 BHP applications. The IAG 1150 Long Block features our IAG 1150 Closed Deck Short Block that utilizes a brand new EJ25 Subaru case that is converted to closed deck and is bored and honed to 99.75mm. The IAG 1150 block features 14mm head stud machining, as well as our Fire-Lock gasket solution that is loosely derived from diesel technology where a counterbore step is machined around each cylinder bore allowing specially sized fire rings to drop into the machined area and head gasket bores. The combination of the alloy compression shims and gaskets assure maximum sealing for a Subaru EJ25 turbocharged engine. The IAG 1150 internals includes IAG-Spec JE FSR 2618 forged pistons that have an Electroless nickel plated coating and wrist pins that are sized to .250" / .927" from H13 material. The pistons are matched to IAG-Spec Tri-Beam connecting rods with ARP 625+ rods bolts, IAG-Spec Billet crankshaft and ARP main bolts. The IAG 1150 block is then paired up with our IAG 1150 Fully CNC Ported Cylinder Heads to deliver maximum flow for high horsepower applications. The heads start as brand new Subaru OEM cylinder head castings that are CNC machined ported inside the intake and exhaust runners. The heads are resurfaced and then outfitted with complete Ferrea valve train components. The heads include +1mm oversized Comp Plus intake and exhaust valves, Ferrea Dual Drag Valve Springs, Titanium Retainers, GSC Manganese Bronze Valve guides as well as your choice of GSC Billet Stage 2 or Stage 3 camshafts and Kelford DLC Coated Lifter Buckets. To complete the package, we add a 14mm ARP head stud set, our Fire-Lock head gasket solution and all required gaskets to complete the valve cover-to-valve cover assembly. 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 Stage 4 Extreme Short Block. The IAG 1150 Short Block starts with brand new Subaru 2.5L EJ25 engine case halves. The case halves are split and the main webs are CNC machined in our Haas VF-4SS CNC mill for 9.5mm pins to reduce distortion and movement of the case in extreme conditions. The case halves are then reassembled and IAG machines the case to accept the IAG CLOSED Deck Inserts that transform the block into a solid deck. The unique inserts feature small passages that allow needed coolant flow to the deck surface. The case halves are then CNC machined for our new Fire-Lock head gasket solution that is loosely derived from diesel technology where a counterbore step is machined around each cylinder bore allowing specially sized fire rings to drop into the machined area and head gasket bores. The IAG 1150 case is CNC drilled and tapped to fit 14mm head studs. Utilizing the new Fire-Lock gasket solution, along with larger IAG / ARP 14mm head studs, nuts, and washers reduce the chances of the heads lifting under extreme boost conditions. The short block is then Deck Plate bored and honed to 99.75mm in our in-house Sunnen SV-30 cylinder hone. IAG's in-house honing process is able to set custom piston to wall clearances to ensure performance an reliability. The IAG 1150 Short Block uses our strongest pistons ever - The IAG-Spec 99.75mm Custom Forged Pistons with .250" / .927" wrist pins feature electroless nickel plated tops and ring area. IAG's custom pistons feature a lightweight design while increasing strength where you need it and are designed to work exclusively with the IAG +2mm Tri-Beam connecting rods. The wrist pin is short and is made from strong H13 tool steel. The pin piers are profiled to increase pin boss strut. Finally, IAG's pistons feature a 25% larger oil ring for reduced oil consumption and added gas ports that aid ring sealing in high boost conditions.
