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.

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 1796 cc; bore and stroke is 83x83 mm. This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces 125 PS at 5,500 rpm and 170 Nm 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 (crank, pistons and rods) in a Suzuki Swift Sport, in order to have more torque on the whole rev band.

Application:
 * Suzuki Aerio (Aust. & N.Z.)
 * Suzuki Liana GS 2004 (Australia & N.Z.) 125 PS
 * 2009-2012 Suzuki SX4 (China) 131 PS
