Engine Long Block - IAG-ENG-L750W

The IAG Performance Hand-Built Subaru EJ25 Closed Deck Long Block Engine Packages are a complete, valve cover to valve cover, crate engine. The Long Blocks feature a combination of our proven IAG Performance 750 Closed Deck Short Block and IAG 750 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 750 Long Block package is ideal for clients looking for an engine package to support up to 750 BHP applications. The IAG 750 long block features our 750 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 750 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 IAG 750 Pocket Ported Cylinder Heads to increase flow, but maintain spool. The heads start as brand new Subaru OEM cylinder head castings that are CNC machined and resurfaced. The heads are outfitted with GSC Standard Size Valves, GSC Viton Valve Stem Seals, GSC Valve Guides, IAG Stage 1 Valve Springs with Titanium Retainers, and OEM Keepers as well as GSC Billet Stage 1 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 Standard Long Block Workmanship Warranty covers your long block for 12 months or 12,000 miles. We have also teamed up with IAG Certified Installation Facilities which offer a 24 month/24,000 mile workmanship warranty when the engine is purchased, installed, and tuned by that IAG Certified Installer.
