Description
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 (per cylinder) 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 almost every year from the list’s inception. The VQ series replaced the VG series of engines.
This engine is similar to the VQ20DE, but has a 2.5 L (2,496 cc) displacement. Bore and stroke are 85 mm × 73.3 mm (3.35 in × 2.89 in), with a compression ratio of 9.8 to 10.3:1. It produces 190 to 210 PS (140 to 154 kW; 187 to 207 hp) at 6400 rpm and 174 to 195 lb⋅ft (236 to 264 N⋅m) of torque. Later versions produce 186 PS (137 kW; 183 hp) at 6000 rpm and 171 lb⋅ft (232 N⋅m) at 3200 rpm. In some Nissans, this engine was replaced by the QR25DE.
