The IAG Performance Hand-Built Subaru EJ25 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 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 600 package is ideal for clients looking for an engine package to support up to 600 BHP applications. The IAG 600 long block features our most popular Stage 2 Tuff short block that utilizes a brand new EJ25 Subaru Case bored and honed to 99.75mm, IAG-Spec JE forged pistons, IAG-Spec H-Beams connecting rods, and OEM STI crankshaft. The block is then paired up with our Stage 2 Cylinder Head Package, which features brand new Subaru WRX STI OEM cylinder head castings that are CNC Pocket Ported to increase flow but maintain spool. The heads include GSC valve train components and GSC Stage 2 camshafts to take advantage of the ported heads. 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.

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. If the previous engine experienced an internal failure then all oiling components (i.e. cooler, pump, pickup, cam gears, and solenoids, etc) as well as other necessary components as per your installer’s recommendations, must be replaced during installation.
