Toyota 1MZ-FE specs: 3.0L (182.7 ci) 6-cylinder, 87.5 x 83 mm (3.4449 x 3.2677 in) bore and stroke, 10.5:1 compression. Rated 188-220 hp, 1994–2006.
The Toyota 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).
10.5:1 is in the range that usually runs on pump premium.
25 factory variants share these dimensions, rated from 188 to 220 hp across 1994–2006.
