IAG 700 EJ25 Closed Deck Long Block w/ Stage 3 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 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 Closed Deck Short Block and 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 700 package is ideal for clients looking for an engine package to support up to 700 BHP applications. The IAG 700 long block features our Stage 2.5 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 Stage 2.5 short block internals include IAG-Spec JE FSR 2618 forged pistons, .210" 9130 pins, IAG-Spec Tuff H-Beam connecting rods with ARP 2000 rods bolts and an OEM STI crankshaft. The block is then paired up with our Stage 3 Pocket Ported Cylinder Heads to increase flow, but maintain spool. The heads start as brand new Subaru OEM cylinder head castings that CNC machined and resurfaced. The heads are outfitted with GSC valve train components, consisting of +1mm oversized intake and exhaust valves as well as GSC Billet Stage 2 camshafts. To complete the package, we add an 11mm ARP 625+ head stud set and all required gaskets for the final valve cover-to-valve cover assembly. IAG's Break-in Instructions MUST be followed, and the long block must be professionally installed for the 12 month/12,000 mile workmanship warranty to be applicable.
