Mahle MS Piston Set Subaru FA20 TURBO 2.0L 86.5mm Bore 86mm Stroke 129.3mm Rod -8cc 10.6 CR Set of 4

Mahle's MS Piston Set is built for the Subaru FA20 TURBO engine, featuring a precise 86.5mm bore. This set is designed to handle the demands of a performance-oriented 2.0L engine, offering a 10.6:1 compression ratio that's well-suited for boosted applications. The pistons themselves weigh in at 326g, with a 22mm pin and a 129.3mm rod length, all contributing to a balanced and robust rotating assembly.

Constructed from 2618 aluminum, a material known for its strength and heat resistance, these pistons are well-suited for the higher temperatures and pressures found in turbocharged engines. The -8.0cc dish volume is a key design element that helps achieve the 10.6:1 compression ratio, striking a good balance between power output and drivability for modified engines. Mahle has engineered these pistons with a 32.5mm compression height and an 86.0mm stroke compatibility, ensuring they integrate properly within the engine's geometry.

This set includes four pistons, ready to be installed in your Subaru's FA20 TURBO engine. Please note that this piston set is not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or a qualified mechanic to ensure proper installation and compatibility with your specific build.
