Our forged Omega 18cc has become the piston of choice for forced induction engines, available in plus-0.020" and 0.040" sizes with standard diameter 13/16" (20.6mm) gudgeon pins.

The large central dish allows for a much reduced compression ratio, all without using problematic decompression plates or very large combustion chambers in the cylinder head.

This, combined with the high strength of Omega forged pistons, makes these the ideal choice for high performance turbo and supercharged engines.
