Mazda Ford Lima 2.5 SOHC I4 specs: 2.5L (153 ci) 4-cylinder, 96 x 86.4 mm (3.7811 x 3.4000 in) bore and stroke, 9.37:1 compression. Rated 119 hp, 1998–2001.
The Mazda Ford Lima 2.5 SOHC I4 is oversquare — the 3.7811" bore exceeds the 3.4" stroke by 11.2% — a layout that favors airflow and RPM over leverage at the crank. The 3.4" stroke does not reach 4,000 ft/min of mean piston speed until about 7,050 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 38.3 ci (627 cc).
9.37:1 is low by modern standards and generally happy on regular pump fuel.
4 factory variants share these dimensions, rated at 119 hp across 1998–2001.
