What material are these pistons made from?

These pistons are forged from domestic 2618 alloy, which is known for its superior strength and performance characteristics, making them well-suited for demanding engine builds.

What is the significance of the 86.10mm bore size and the +.1mm designation?

The 86.10mm bore size indicates these pistons are slightly larger than the stock bore. The +.1mm designation means they are 0.1mm over the standard bore size, typically used when re-boring cylinders to clean up imperfections or achieve a specific clearance.

Are these pistons compatible with all FA20 engines?

This specific piston set is designed for the 2013 and later Subaru BRZ FA20 engine. It is important to confirm compatibility with your exact engine model and year, as variations can exist.

About this part

Product Details

Manley Performance is well-known for building strong engine components that serious tuners and builders trust. This piston set is designed for the 2013 and later Subaru BRZ with the FA20 engine, featuring an 86.10mm bore size, which is a +.1mm overbore from stock. These pistons have a 10:1 compression dish, making them a solid choice for rebuilding or upgrading your engine.

These pistons are forged from domestic 2618 alloy, a material chosen for its superior strength and performance under demanding conditions. They feature proven cam and barrel skirt profiles, which help generate power while being gentle on your cylinder walls. Manley also pays close attention to the ring lands and grooves, holding them to strict standards to ensure an enhanced ring seal, which translates directly to more power. The included wrist pins are made of premium Chrome Moly for added durability.

When you're rebuilding an engine, the precision of the components matters. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation. This ensures ultimate squareness between the ring groove and the piston skirt, contributing to a more reliable and powerful engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
