Nissan SD22 specs: 2.2L (132 ci) 4-cylinder, 83 x 100 mm (3.2677 x 3.9370 in) bore and stroke. Built 1982–1983. Used in the Nissan Datsun / Nissan Pickup.
The Nissan SD22 is undersquare — the 3.937" stroke exceeds the 3.2677" bore by 17.0% — a layout that trades peak RPM for leverage and torque low in the range. The 3.937" stroke puts mean piston speed at 4,000 ft/min around 6,100 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 33.0 ci (541 cc).
2 factory variants share these dimensions across 1982–1983.
