For a Honda street engine that will run on pump gas, the maximum compression that should be run is in the low 11:1 range. The reason why Hondas can get away with this high compression ratio with modern unleaded fuel is mostly because of their superior combustion chamber shape and small bore diameters. Higher compression than this requires racing gas to avoid detonation. With cast pistons detonation should be avoided at all costs as they are more brittle than forged pistons.

Any c/r under 12:1 more then fine for a n/a street application.

Ideal c/r is 11.5:1 for pump gas on a n/a street application.

Some people preffer using anything under 12.5:1 for street applications... to each is own.
