Nissan MA10S

The MA10S is the engine used in the K10 (1982–1992) type Nissan Micra. It has a hemi-head and, unusually, the spark is fired after top dead centre because of the very high flame speed in a compact engine with this head design. Compression in the 50bhp version was relatively low so it was able to run on 90 RON petrol where available.
