The IAG Performance Hand-Built 550 Subaru EJ25 Long Block Packages are a complete, valve cover to valve cover, crate engine.

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 550 package is ideal for clients looking for a long block engine package to support up to 550 BHP applications. The IAG 550 long block features our highly popular IAG 550 Short Block that utilizes a brand new EJ25 Subaru case, 99.5mm IAG-Spec JE forged pistons, IAG Spec H-Beam connecting rods and OEM STI Crank. The block is then paired up with our IAG 550 Cylinder Head Package which features Subaru WRX STI OEM cylinder head castings and GSC valvetrain components. To complete the package, we add an 11mm ARP 2000 head stud set and all required gaskets for the final valve cover-to-valve cover assembly. We stand behind every hand-built engine we produce. IAG's Standard Long Block Workmanship Warranty covers your long block for 12 months or 12,000 miles. We have also teamed up with a selection of IAG Certified Installation Facilities which offer up to a 24 month/24,000 mile workmanship warranty when the engine is purchased, installed, and tuned by that IAG Certified Installer. These engines offer significant ease of installation for customers seeking a complete "drop-in" engine package for their Subaru WRX, STI, Forester XT or Legacy GT.
