Lexus 2GR-FE specs: 3.5L (211 ci) 6-cylinder, 94 x 83 mm (3.7008 x 3.2677 in) bore and stroke, 10.8:1 compression. Rated 270 hp. Rod ratio and piston speed.
The Lexus 2GR-FE is oversquare — the 3.7008" bore exceeds the 3.2677" stroke by 13.3% — 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 35.2 ci (576 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 7 engines in the GR family, sitting between the 201.4 ci and 211.8 ci members. Factory fitments include the Lexus ES 350, Lexus RX 350, Lexus IS 350 and 1 other.
