Lexus V35A-FTS specs: 3.4L (207 ci) 6-cylinder, 85.5 x 100 mm (3.3661 x 3.9370 in) bore and stroke, 10.5:1 compression. Rated 409 hp. DOHC.
The Lexus V35A-FTS is undersquare — the 3.937" stroke exceeds the 3.3661" bore by 14.5% — a layout that trades peak RPM for leverage and torque low in the range. The 3.937" stroke puts mean piston speed at 4,000 ft/min around 6,100 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 34.5 ci (565 cc).
10.5:1 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 15 engines in the Dynamic Force family, sitting between the 121.9 ci and 210 ci members. Factory fitments include the Lexus LX 600, Lexus GX 550, Lexus LS 500 and 3 others.
