Wossner S2000 F20C Turbo Low Compression Forged Piston Kit Hard Anodised

Wossner S2000 F20C Turbo Low Compression Forged Piston Kit Hard Anodised

The Wossner S2000 F20C Turbo Low Compression Hard Anodised Piston Kit is the ultimate internal solution for extreme horsepower forced-induction builds. Recognising that the high-revving F20C generates immense cylinder heat when turbocharged, Wossner has equipped this kit with a professional Hard Anodised crown coating. This treatment acts as a sophisticated thermal barrier, protecting the piston substrate from heat erosion and preventing ring micro-welding—a common failure point in high-boost S2000 engines where the piston ring can fuse to the groove under extreme stress.

By dropping the compression ratio to 9.0:1, this kit provides the safety margin required for aggressive boost mapping on pump gas or race fuels. Each piston is manufactured from high-silicon 4032-T6 forged aluminium in Wossner’s German facility, ensuring the structural integrity to withstand 500+ bhp builds. The combination of a low-expansion alloy and Wossner’s signature Moly skirt coating ensures that your engine remains quiet during cold starts while providing the lowest possible friction at high RPM.

Key Performance Features

• Turbo-Optimised 9.0:1 Compression: Engineered to allow for high boost levels while significantly reducing the risk of engine-damaging detonation.

• Hard Anodised Crown Coating: Provides a ceramic-like thermal shield that increases piston longevity and resists surface melting under lean conditions.

• Anti-Micro-Welding Protection: The anodised ring lands ensure the rings remain free and functional even under extreme thermal loads and cylinder pressures.

• 4032-T6 Forged Alloy: Premium material choice for a street/track crossover, offering high strength with minimal thermal expansion.

• Moly-Coated Skirts & Polished Crowns: Dual-stage finishing reduces internal drag and eliminates sharp edges that could cause pre-ignition.
