Nissan GA16DE specs: 1.6L (98 ci) 4-cylinder, 76 x 88 mm (2.9921 x 3.4646 in) bore and stroke. Rated 110-115 hp, 1991–1998. Used in the Nissan NX.
The Nissan GA16DE is undersquare — the 3.4646" stroke exceeds the 2.9921" bore by 13.6% — a layout that trades peak RPM for leverage and torque low in the range. The 3.4646" stroke puts mean piston speed at 4,000 ft/min around 6,950 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 24.5 ci (401 cc).
It is one of 4 engines in the Nissan 98ci family, all of them 98 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated from 110 to 115 hp across 1991–1998.
