Subaru WRX FA20 DIT Stage 2.5 Closed Deck Short Block by IAG Performance
The IAG Stage 2.5 short block starts with new Subaru FA 2.0L engine case halves that are machined for improved oiling. Then IAG machines the case halves assembled together in our Haas VF-4SS CNC mill to accept the IAG CLOSED Deck Inserts that transform the block into a solid deck. The unique inserts feature small passages that allow needed coolant flow to the deck surface.
