Supertech Block Guard for Honda S2000

Supertech is known for making well-built valvetrain components, and this block guard is a solid option for Honda S2000 owners looking to add strength to their engine block. If you're planning on increasing boost pressure or making more power, the factory cylinder walls can sometimes flex, leading to issues. This block guard is designed to brace the cylinder walls from the inside, helping to prevent that flex and keep your engine running reliably under higher loads.

This part is made from a strong aluminum alloy, which is a good choice because it won't add excessive weight to your engine. It fits between the cylinder sleeves, effectively tying them together and reinforcing the entire deck area. It’s a common modification for boosted S2000 builds where the stock block needs a little extra support to handle the increased cylinder pressures. Installation involves removing the cylinder head and dropping this piece into place before reassembling.
