Lexus 1MZ-FE specs: 3.0L (182.7 ci) 6-cylinder, 87.5 x 83 mm (3.4449 x 3.2677 in) bore and stroke. Used in the Lexus ES and Toyota Camry.
The Lexus 1MZ-FE is oversquare — the 3.4449" bore exceeds the 3.2677" stroke by 5.4% — a layout that favors airflow and RPM over leverage at the crank. The 3.2677" stroke does not reach 4,000 ft/min of mean piston speed until about 7,350 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 30.5 ci (499 cc).
It is one of 3 engines in the MZ family, the smallest at 182.7 ci.
