What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications like turbocharged engines.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design helps to minimize friction and power loss by reducing the piston skirt width. It also saves additional weight with a shorter wrist pin, contributing to overall engine efficiency.

Are these pistons compatible with all L15B Turbo engines?

These pistons are designed specifically for the Honda L15B7 Turbo engine with a 73.5mm bore and a 9.5:1 compression ratio. It is important to verify that your engine's specifications match these requirements. They are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance Honda L15B Turbo engine, a strong set of pistons is crucial. These JE Pistons are designed specifically for that engine, offering a 9.5:1 compression ratio with a -14cc inverted dome. This setup is ideal for turbocharged applications where you need to manage boost and heat effectively.

JE Pistons uses a proprietary forged side relief (FSR) design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. They're forged in the USA from 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for the demands of boosted engines. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating can also be present to further reduce friction and wear, leading to quieter operation and longer life.

This set includes four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components ready for installation. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
