M18A

The M18A is based on the previous M16a, with a larger bore. It displaces 1.8 L (1,796 cc); bore and stroke is 83 mm × 83 mm (3.27 in × 3.27 in). This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces 92 kW (123 hp) at 5,500 rpm and 170 N⋅m (125 lb⋅ft) 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.
