Wiseco BMW M50B25 2.5L 24V Turbo 84.50MM Bore +0.50 Oversized 8.8:1 CR Piston - Single

This is a single Wiseco forged piston designed for the BMW M50B25 2.5L 24V engine, specifically when building a turbocharged setup. It features a bore size of 84.50mm, which is 0.020 inches (0.50mm) oversized from the stock dimension, and a compression ratio of 8.8:1, suitable for boosted applications where lower compression helps prevent detonation.

Wiseco is known for making well-built internal engine components, and these pistons are forged from high-strength aluminum alloy. Forging creates a stronger, more durable piston than casting, which is important for handling the increased cylinder pressures and temperatures found in turbocharged engines. This particular piston is sold individually, allowing you to replace exactly what you need or build your engine with custom configurations. Remember that this piston is not CARB approved and cannot be shipped to California.
