Acura Honda J-series specs: 3.5L (212.2 ci) 6-cylinder, 89 x 93 mm (3.5039 x 3.6614 in) bore and stroke, 10:1 compression. Rated 210-255 hp. SOHC.

The Acura Honda J-series is close to square: 3.5039" bore against 3.6614" stroke, within 4.3%, which splits the difference between a high-revving layout and a torque layout. The 3.6614" stroke puts mean piston speed at 4,000 ft/min around 6,550 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 35.4 ci (580 cc).

10:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.

It is one of 10 engines in the Honda J-series family, sitting between the 182.9 ci and 225.7 ci members. 4 factory variants share these dimensions, rated from 210 to 255 hp. Factory fitments include the Honda Odyssey, Honda Pilot, Honda Ridgeline and 1 other.
