The IAG Performance Hand-Built Subaru EJ20 Closed Deck Long Block Engine Packages are a complete, valve cover to valve cover, crate engine. The Long Blocks feature a combo of our IAG 950 Closed Deck Short Block and IAG 950 Cylinder Head packages. 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 950 package is ideal for clients looking for an engine package to support up to 950 BHP applications. The IAG 950 Long Block features our IAG 950 Closed Deck Short Block that utilizes a brand new EJ25 Subaru case that is converted to closed deck and is bored and honed to 92.5mm. The IAG 950 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 IAG 950 internals include IAG-Spec JE FSR 2618 forged pistons, .250" / .906" H13 pins, IAG-Spec Tuff H-Beam +2mm connecting rods with ARP 625+ rods bolts and an OEM STI crankshaft. The block is then paired up with our IAG 950 Fully CNC Ported Cylinder Heads to deliver max flow for high HP applications. The heads start as brand new Subaru OEM cylinder head castings that are CNC machined and resurfaced. The heads are outfitted with GSC valve train components, consisting of +1mm oversized intake and Super Alloy exhaust valves, IAG Beehive Springs, as well as GSC Billet Stage 2 camshafts. To complete the package, we add an IAG / ARP 14mm head stud set and all the required gaskets for the final valve cover-to-valve cover assembly. IAG's Standard Long Block Workmanship Warranty covers your long block for 12 months or 12,000 miles.
