Supertech Honda B20 Block B16 Head 85mm Bore +8cc Dome 13.5:1 CR Pistons - Set of 4 (Excl Rings)

These Supertech pistons are forged from high-strength aluminum, a material chosen for its excellent strength-to-weight ratio, making them well-suited for high-performance engine builds. Each piston features an 85mm bore and a +8cc dome shape, specifically designed to work with a B16 cylinder head on a B20 block. This combination, along with the piston's design, achieves a 13.5:1 compression ratio, which is notably higher than stock and intended for naturally aspirated or forced induction setups where increased power is the goal.

The forged construction means these pistons are significantly stronger and more durable than cast pistons, allowing them to withstand the higher cylinder pressures and temperatures common in modified engines. The precise machining and the specific dome volume are critical for achieving the target compression ratio and ensuring proper piston-to-valve clearance when paired with a B16 head. This set includes four pistons, but remember that piston rings are sold separately, so you'll need to source those to complete the assembly.

When rebuilding or modifying your Honda B-series engine, choosing pistons that can handle the increased demands is crucial. These Supertech pistons offer a well-built solution for enthusiasts looking to push the performance envelope. Always consult your engine builder or a trusted mechanic to ensure these pistons are the right choice for your specific build and to confirm all necessary clearances and components are accounted for before installation.
