The Rover T16 engine was a 1997 cc fuel injected DOHC inline-four petrol engine produced by Rover from 1992 to 1999. It has a bore of 84.45 mm (3.325 in) and a stroke of 89 mm (3.5 in). It is a development of the M series (M16), which was in turn a development of the O series, which dated back to the BMC B-series engine as found in the MG B and many others. Several variants were produced for various models, but all had the same displacement. The naturally aspirated type produced 136 horsepower (101 kW), and turbocharged types were available with 180 and 200 hp (150 kW).
