Supertech Honda B20 Block B16 Head 86mm Bore +8cc Dome 13.5:1 CR Pistons - Set of 4 (Excl Rings)

If you're building a high-performance Honda engine using a B20 block with a B16 cylinder head, these Supertech pistons are a key component for achieving a significant compression increase. Designed for an 86mm bore, they are specifically made to work with the B16 head, creating a potent combination for boosted or naturally aspirated setups that demand more power. The +8cc dome volume, when paired with the B16 head, results in a substantial 13.5:1 compression ratio, which is ideal for maximizing output in performance applications.

These pistons are forged from high-strength aluminum, a material chosen for its ability to withstand the extreme pressures and temperatures found in a performance engine. Forging creates a denser, more durable grain structure compared to cast pistons, making them much more resistant to detonation and mechanical stress. This set includes four pistons, ready to be fitted into your B20 block. Keep in mind that piston rings are not included with this set and will need to be purchased separately to complete the installation.

When undertaking an engine build of this caliber, precision is paramount. Ensure you have the correct ring set that matches the 86mm bore and the specific groove dimensions for these pistons. Proper installation, including correct ring gapping and lubrication, is crucial for the longevity and performance of your new engine.
