VALVES - 31.5mm EXHAUST (Nissan VQ35DE)

The 3.5L (3498 cc) VQ35DE is used in many modern Nissan vehicles, but the most popular US chassis for engine upgrades are the Nissan 350z and the Infiniti G35. Unlike the inline six cylinders (RB26, 2JZ), the VQ35DE is a V6 configuration. It adds variable valve timing and has a stock bore of 95.5 mm and stroke of 81.4 mm. Output ranges from 240 hp to 301 hp (179 to 225 kW) and 246 ft·lbf to 287 ft·lbf (334 to 390 Nm). The VQ35DE is built in Iwaki, Japan and Decherd, TN. It was on the Ward's 10 Best Engines list for 2002 through 2006, the only engine to be on Ward's list every year since it's inception. The VQ35DE has an aluminum engine block and aluminum DOHC cylinder heads. It uses SFI fuel injection, has 4 valves per cylinder with VVT and features Nissan's nylon intake manifold technology. A modified version of the VQ35DE, called the S1 is produced by Nismo for the Fairlady Z S-Tune GT. It produces 300 ps or 285 hp (220 kW) at 7200 rpm, a higher rev-limit than that of the original VQ35DE.

BC valves are made from premium stainless steel, fully machined and swirl polished for ultimate air flow. Dished head for added weight savings and increased valve control at high rpm. Standard and oversize head.
