Supertech Honda B16 83mm Bore 5.9cc Dome 10.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're rebuilding the top end of your Honda B16 engine and aiming for improved performance, a set of forged pistons like these from Supertech is a solid foundation. These pistons are specifically sized for an 83mm bore, and their dome shape is designed to achieve a 10.5:1 compression ratio when paired with the correct cylinder head and gasket combination. This compression level is a popular choice for naturally aspirated builds looking for a noticeable bump in power and throttle response without going too extreme for pump gas.

Supertech uses a forged aluminum process for these pistons, which creates a much stronger and more durable component compared to cast pistons. This strength is crucial for handling the increased cylinder pressures and temperatures that come with higher compression and performance tuning. The 5.9cc dome volume is a key specification that helps achieve the target 10.5:1 compression ratio, and it's important to ensure your cylinder head volume and head gasket thickness are accounted for to hit this ratio accurately. Remember that these pistons come as a set of four and do not include piston rings, so you'll need to source those separately.

When undertaking an engine rebuild of this caliber, precision is key. Ensure all mating surfaces are clean and properly prepped, and always refer to the manufacturer's detailed installation instructions for critical measurements and assembly procedures. These pistons are a significant upgrade for enthusiasts looking to extract more performance from their B16 engine.
