IAG 600 EJ25 Long Block Engine w/ Stage 2 W25 Heads

The IAG Performance Stage 1 Short Block is a great idea for those of you who want a brand-new replacement motor that has been balanced, blueprinted, and assembled by one of the leaders in the Subaru performance industry. This is a complete valve cover to valve cover assembled long block crate engine that has been assembled with proven performance components to sustain power levels up to 600 BHP.

The IAG 600 is ideal for those of you looking to make up to 600 BHP with the right turbo and fuel setup, and it features IAG's most popular Stage 2 Tuff short block that utilizes a brand new Subaru EJ25 case that is bored to 99.75mm to accept IAG Spec-JE forged pistons, IAG-Spec H-beam connecting rods, and a brand new OEM STI crankshaft. This block is paired with IAG Stage 2 Heads that feature brand new Subaru OEM WRX/STI cylinder head castings that are CNC pocket ported to increase flow while maintaining spool. These heads will include GSC valve train components along with GSC Stage 2 billet camshafts to optimize the ported heads. To complete the package, the heads are fastened using ARP 2000 head studs along with all of the required gaskets for the final assembly.
