The 4U-GSE Forged Pistons Subaru FA20, with a bore size of 86mm and a compression ratio of 9.0:1, is an exceptional upgrade for your Subaru FA20 engine. These pistons are crafted from high-quality forged 2618 alloy, ensuring superior strength, durability, and heat resistance.
The piston skirts are designed with a unique profile, featuring a honed finish and a low oil consumption groove. This combination reduces friction, minimizes oil consumption, and promotes optimal engine efficiency. The piston tops are equipped with a reciprocating weight-reduced dish and a second oil control ring groove. This design ensures accurate piston-to-ring seal, reduces the risk of piston slap, and further reduces oil consumption.
The piston rings are made from high-temperature, low-friction materials. They are designed to minimize ring groove distortion, maintain proper compression, and provide a consistent seal throughout the engine's operating cycle. The piston pin is made from strong, heat-resistant material, while the wrist pin retainer uses a high-tensile, cold-forged steel design for increased strength and durability.
The 4U-GSE Forged Pistons Subaru FA20 are designed to work seamlessly with high-performance engine components, such as high-compression cylinder heads, high-flow intakes, and high-performance camshafts. They are an excellent choice for enthusiasts seeking improved engine performance, increased power output, and enhanced reliability for their Subaru FA20 engine.
In summary, the 4U-GSE Forged Pistons Subaru FA20 are a high-quality, performance-focused upgrade for your Subaru FA20 engine. Their unique design features, including forged construction, honed skirts, and weight-reduced dishes, ensure superior strength, efficiency, and reliability.
