See other engines in this family

Lexus 1MZ-FE specs: 3.0L (183 ci) 6-cylinder, 87.5 x 83 mm (3.4449 x 3.2677 in) bore and stroke. Rated 188-220 hp, 1994–2003. Used in the Lexus ES.

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 (500 cc).

It is one of 2 engines in the Lexus 183ci family, all of them 183 ci — the differences between them are in compression, heads and rating, not displacement. 15 factory variants share these dimensions, rated from 188 to 220 hp across 1994–2003.

What these numbers mean

Bore/stroke character	1.054 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves
Mean piston speed at 6,000 RPM	3,268 ft/min — conservative for a street engine
Displacement per cylinder	30.5 ci
