Porsche EA839 3.0T specs: 3.0L (183 ci) 6-cylinder, 84.5 x 89 mm (3.3268 x 3.5039 in) bore and stroke, 11.2:1 compression. Rated 335-512 hp, 2019–2026.
The Porsche EA839 3.0T is undersquare — the 3.5039" stroke exceeds the 3.3268" bore by 5.1% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5039" stroke puts mean piston speed at 4,000 ft/min around 6,850 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 30.5 ci (500 cc).
11.2:1 is high enough that pump premium or better is normally required.
It is one of 3 engines in the Porsche 183ci family, all of them 183 ci — the differences between them are in compression, heads and rating, not displacement. 16 factory variants share these dimensions, rated from 335 to 512 hp across 2019–2026.
