IAG Stage 2.5 FA20 Subaru Closed Deck Short Block 10.01 Compression Ratio

RallySport Direct now carries highly sought-after high-performance upgrades and accessories brought to you by IAG Performance. 

Here, you are looking at the IAG Performance Stage 2.5 FA20 Short Block. IAG started with a new Subaru FA 2.0L engine case halves that are assembled together using the Haas VF-4SS CNC mill to accept the IAG CLOSED Deck inserts that will transform the block into a solid deck. These unique inserts feature small passages that allow needed coolant flow to the deck surface.
