Mitsubishi 6G75 SOHC specs: 3.8L (232 ci) 6-cylinder, 95 x 90 mm (3.7402 x 3.5433 in) bore and stroke, 10:1 compression. Rated 215 hp, 2003–2006.
The Mitsubishi 6G75 SOHC is oversquare — the 3.7402" bore exceeds the 3.5433" stroke by 5.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.5433" stroke puts mean piston speed at 4,000 ft/min around 6,750 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 38.7 ci (634 cc).
10:1 is in the range that usually runs on pump premium.
It is one of 3 engines in the Mitsubishi 232ci family, all of them 232 ci — the differences between them are in compression, heads and rating, not displacement. 4 factory variants share these dimensions, rated at 215 hp across 2003–2006.
