IAG 900 EJ25 Closed Deck Long Block w/ Stage 4 Heads: 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 easy installation for customers seeking a complete "drop-in" engine package for their WRX, STI, Forester XT or Legacy GT. The Long Blocks feature a combo of our proven IAG Performance Closed Deck Short Block and Cylinder Head packages, along with other race-proven components to complete the assembly. When paired with our Long Block Install 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 900 package is ideal for clients looking for an engine package to support up to 900 BHP. The IAG 900 Long Block features our Magnum 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 Magnum block features 14mm head stud machining, as well as our Fire-Lock gasket solution. The combination of the alloy compression shims and gaskets in the Fire-Lock system assure maximum sealing for a Subaru EJ25 turbocharged engine. The Magnum internals includes 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 Stage 4 Fully CNC Ported Cylinder Heads to deliver maximum flow for high hp applications. The heads start as new Subaru OEM castings that are CNC machined and resurfaced. The heads are outfitted with GSC valve train components including +1mm oversized intake and SuperAlloy exhaust valves, Beehive Springs and 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.
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.
