The S20 features a dual overhead cam, cross-flow head with four valves per cylinder, and hemispherical combustion chambers. Early versions were fed via triple Weber 40DCOE carbs; models after 1969 featured Lucas mechanical fuel injection. In racing trim, the fuel-injected motors reportedly produced over 225 bhp, with 250 bhp for larger tracks like Fuji Speedway.
