IAG 800 FA20 Subaru Closed Deck Short Block - 800 BHP

IAG 800 FA20 Short Block for 2013-20 BRZ / FR-S / GT86 (10.5:1 Compression Ratio)

BUILT FOR BOOSTED FA20 BUILDS

The IAG 800 Short Block is designed for modified FA20 BRZ/FR-S/GT86 applications that need a stronger foundation to handle the added cylinder pressure created by larger aftermarket turbochargers. Built around IAG’s closed-deck cylinder support system, it reinforces the OEM FA20 cylinder walls for high-boost reliability.

With upgraded internals and IAG’s machining and assembly processes, the IAG 800 is a proven base for serious forced-induction power goals when paired with the proper supporting modifications.

CLOSED DECK CYLINDER SUPPORT SYSTEM

IAG’s proprietary closed-deck system increases strength where the FA20 needs it most by supporting the upper cylinder area. This helps reduce cylinder wall movement and improves durability under heavy boost.

The closed-deck design maintains coolant flow pathways to support street and track use while providing the added structure required for high-horsepower builds.

FORGED CONNECTING RODS

The IAG 800 short block is equipped with IAG-Spec H-beam forged connecting rods designed to withstand high cylinder pressure and the demands of boosted power. This upgraded rod package is selected to match the performance goals of the 800 BHP rating.

ASSEMBLED FOR PERFORMANCE + RELIABILITY

Built as a complete short block solution, the IAG 800 is assembled with performance bearings and precision machining practices to deliver a consistent, ready-to-install foundation for your FA20 build.
