Lexus 3MZ-FE specs: 3.3L (202 ci) 6-cylinder, 92 x 83 mm (3.6220 x 3.2677 in) bore and stroke, 10.8:1 compression. Rated 218-268 hp, 2004–2008.
The Lexus 3MZ-FE is oversquare — the 3.622" bore exceeds the 3.2677" stroke by 10.8% — 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 33.7 ci (552 cc).
10.8:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.
It is one of 3 engines in the MZ family, the largest at 202 ci. 9 factory variants share these dimensions, rated from 218 to 268 hp across 2004–2008.
