3.0L 24v - C30SE 

The C30SE is Opel's three-litre 24-valve straight-six, the only naturally aspirated six-cylinder in our OPEL engine range. Twin overhead camshafts, twenty-four valves: it powers the Omega A 3000 24V and forms the base of the Lotus Omega, also badged Lotus Carlton. Torque and revs climb together, and the bottom end feels it as soon as the build moves away from standard. This page is deliberately narrow: it currently carries one active part, the WISECO forged pistons made for the C30SE. Machined from forged blanks, they replace the cast originals and take the combustion pressure of a reworked engine. Need another family for this block? Send us your engine code.
