Nissan MRA8DE specs: 1.8L (110 ci) 4-cylinder, 79.7 x 90.1 mm (3.1378 x 3.5472 in) bore and stroke, 9.9:1 compression. Rated 124-130 hp, 2013–2019.
The Nissan MRA8DE is undersquare — the 3.5472" stroke exceeds the 3.1378" bore by 11.5% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5472" 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 4 cylinders displaces 27.5 ci (451 cc).
9.9:1 is in the range that usually runs on pump premium.
It is one of 2 engines in the Nissan 110ci family, all of them 110 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated from 124 to 130 hp across 2013–2019.
