Dodge EGJ specs: 215 ci (3.5L) 6-cylinder, 3.78 x 3.189 in (96 x 81 mm) bore and stroke. Rated 234 hp, 2002–2004. Used in the Dodge Intrepid. SOHC.
The Dodge 215ci (EGJ) is oversquare — the 3.7795" bore exceeds the 3.189" stroke by 18.5% — a layout that favors airflow and RPM over leverage at the crank. The 3.189" stroke does not reach 4,000 ft/min of mean piston speed until about 7,550 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 35.8 ci (587 cc).
It is one of 3 engines in the Dodge 215ci family, all of them 215 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions, rated at 234 hp across 2002–2004.
