FA20DIT Magnum Closed Deck Short Block

The Outfront Motorsports FA20DIT Magnum Closed Deck Short Block is engineered for the 2015-2021 Subaru WRX, offering a robust solution for high-output performance builds. This short block is constructed with seasoned FA20 DIT WRX case halves (E20) that have been closed deck for increased strength. It is rated to handle up to 800 BHP, making it suitable for demanding applications. The internal components include custom CP forged pistons (standard 10.6:1 CR, with other options available), Carrillo Pro-H connecting rods with 3/8" CARR bolts, and King Performance bearings for enhanced durability and reliability. A new OEM Subaru heat-treated crankshaft provides a solid foundation. Further enhancing its performance capabilities, the block is machined to accept Outfront Motorsports 1/2" head studs. These studs are sold separately. The default piston configuration is a 10.6:1 Custom CP, but alternative block configurations can be selected to meet specific build requirements.
