About this part

Product Details

Wiseco is well-known for making strong internal engine components, especially for performance applications. This piston kit is a prime example, built for Subaru FA20 2.0L engines. If you're rebuilding the top end of your FA20, these pistons are designed to handle the demands of a performance build, offering a solid foundation for increased power and reliability.

This kit features pistons with a standard 86mm bore, meaning they're ready to go into a freshly machined block without needing an overbore. The compression height is 1.285 inches, and the pistons have a -9.5cc dome dish, which results in a 10.5:1 compression ratio. This compression ratio is a popular choice for naturally aspirated or lightly boosted setups, striking a good balance between power and drivability. The forged construction means these pistons are significantly stronger than cast pistons, making them more resistant to detonation and the higher stresses found in performance engines.

When installing these pistons, remember they are designed for a specific engine configuration. Ensure your block is properly machined to the correct bore size and that all other internal components are balanced and within spec. This kit includes the pistons; rings, wrist pins, and locks are typically sold separately, so be sure to check what you need to complete your engine build. Please note that this kit is not CARB approved and cannot be shipped to California.
