Wossner Integra GSR B17A1 Turbo Low Compression Forged Piston Kit

Ultimate Wossner Turbo Low Comp Forged Piston Kit for Honda Integra GSR B17A1

Maximise the boost potential of your Honda B-Series engine with the Wossner Turbo Low Comp Forged Piston Kit. Specifically engineered for the Integra GSR B17A1 (1992-1993), these pistons are the definitive choice for tuners looking to build a high-horsepower, reliable turbo conversion. By lowering the compression ratio to approximately 9.0:1, this kit allows for significantly higher boost levels and advanced timing while maintaining a safety margin against detonation.

Precision-crafted in Germany using 4032-T6 forged aluminium alloy, Wossner pistons provide the structural strength required to handle increased cylinder pressures. The low-expansion alloy allows for tighter piston-to-bore clearances, ensuring a quieter engine and improved longevity for high-performance street and track builds.

Key Features & Advantages:

• Moly Skirt Coating: Every piston features a high-tech Molybdenum Disulphide coating to reduce friction and heat, protecting your cylinder walls under the intense load of turbocharging.

• Mirror Polished Crowns: The polished finish prevents carbon buildup and eliminates "hot spots" that cause pre-ignition—vital for forced induction reliability.

• Reduced Compression Ratio: Expertly designed with a -6.3cc dish volume to achieve a turbo-friendly 9.0:1 CR, providing the perfect foundation for a stable boost curve.

• Heavy Duty Pins: The kit includes reinforced 21mm gudgeon pins and high-tensile circlips to ensure the rotating assembly remains secure under high torque.
