NISSAN 3.0 VQ30DE

The 3.0 L (2,987 cc) VQ30DE has a bore and stroke of 93 mm and 73.3 mm respectively with a compression ratio of 10.0:1. It produces 193 PS (142 kW; 190 hp) to 230 PS (170 kW; 230 hp) @ 6400 rpm and 205 to 217 lb·ft (278 to 294 N·m) @4400 rpm. The VQ30DE was on the Ward's 10 Best Engines list from 1995 through 2001. It is an aluminum open deck block design with microfinished internals and a relatively light weight. An improved version of the VQ30DE is known by the designation VQ30DE-K. The K designation stands for the Japanese word kaizen which translates to "improvement". The engine was used in the 2000–2001 Nissan Maxima and adds a true dual-runner intake manifold for better high-end performance compared to some earlier Japanese and Middle-East market versions of this engine (2000-2001 Infiniti I30 models added an additional fenderwell intake, boosting power to 227 bhp). The VQ30DEK produces 226 PS (166 kW; 223 hp). The 1995–1999 US spec VQ30DE was equipped with only a single runner intake manifold.[WIKI]
