Porsche EA390 VR6 3.6 specs: 3.6L (220 ci) 6-cylinder, 89 x 96.4 mm (3.5039 x 3.7953 in) bore and stroke. Rated 290-300 hp, 2007–2018.
The Porsche EA390 VR6 3.6 is undersquare — the 3.7953" stroke exceeds the 3.5039" bore by 7.7% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7953" stroke puts mean piston speed at 4,000 ft/min around 6,300 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 36.7 ci (601 cc).
It is one of 3 engines in the Porsche 220ci family, all of them 220 ci — the differences between them are in compression, heads and rating, not displacement. 11 factory variants share these dimensions, rated from 290 to 300 hp across 2007–2018.
