High Quality Content by WIKIPEDIA articles! The VQ is a V6 piston engine produced by Nissan with displacements varying from 2.0 L to 4.0 L. It is an aluminum block DOHC 4-valve design with aluminum heads. It is fitted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Later versions feature various implementations of variable valve timing and replace MPFI with direct fuel injection (marketed as NEO-Di). The VQ series engine was honored by Ward's 10 Best Engines list every year from the list's inception until 2008. This DOHC 24-valve 2.0 L (1995 cc) V6 has bore and stroke dimensions of 76 mm and 73.3 mm respectively, along with a compression ratio ranging from 9.5 to 10.0:1. It produces 150 PS (110 kW; 150 hp) to 160 PS (120 kW; 160 hp) @6400 rpm and 137 to 145 ft·lbf (186 to 197 N·m) @4400 rpm (lean burn).
