Suzuki M engine


The Suzuki M engine family is a line of automobile engines from Suzuki. Ranging in displacement from 1.3 L to 1.8 L, it is a modern engine line with dual overhead cams, 16 valves, and multi-point fuel injection (MPFI). Fully developed in-house following Suzuki's separation from General Motors, the M engine replaced the long-lived G engine family.

M16A

The M16A displaces. Bore is and stroke. This engine has a DOHC variable valve timing valve train and a multipoint injection system. The engine had many iterations, depending on the car in which it was installed and the intended use of the car. The M16A engine uses a chain cam instead of a cam belt.

M18A

The M18A is based on the M16A, with a larger bore. It is the only M-series engine to use a different bore. It displaces ; bore and stroke is. This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces at 5,500 rpm and at 4,200 rpm.
Due to the engine block being based on the same casting, a M16A cylinder head can be bolted onto a M18a shortblock with minor modifications. This has been done by tuners, by installing a M18A block with the stock internals in a Suzuki Swift Sport, in order to have more torque on the whole rev band.
