Subaru Engine Blocks & Internals

IAG’s staged short blocks (Stage 2, 2.5, 3, and beyond) are the gold standard for EJ and FA engine builds. Each block is machined with extreme precision to ensure reliability under high horsepower. Complement your build with IAG’s CNC-machined TGV deletes and competition-series oil pans.

IAG Air Oil Separators (AOS)

Protect your engine from oil blow-by and carbon buildup. The IAG AOS is a "must-have" modification for any turbocharged Subaru, maintaining intake tract cleanliness and reducing the risk of detonation—essential for the Australian climate and track conditions.

Fueling & Cooling Upgrades

Precision fueling is critical for performance. We stock IAG top-feed fuel rails, braided lines, and high-flow injectors designed for seamless integration. Pair these with IAG’s cooling system expansion tanks to keep your temps stable during spirited driving.
