Isuzu X22SE specs: 2.2L (134 ci) 4-cylinder, 86 x 94.6 mm (3.3858 x 3.7244 in) bore and stroke. Rated 130 hp, 1998–2003. Used in the Isuzu Amigo.
The Isuzu X22SE is undersquare — the 3.7244" stroke exceeds the 3.3858" bore by 9.1% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7244" stroke puts mean piston speed at 4,000 ft/min around 6,450 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 33.5 ci (549 cc).
It is one of 3 engines in the Isuzu 134ci family, all of them 134 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated at 130 hp across 1998–2003.
