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 DOHC 24-valve 2.0 L (1,995 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 lb·ft (186 to 197 N·m) @4400 rpm (lean burn).
It is fitted to the following vehicles:
The VQ23DE is a 2.3 L (2,349 cc) engine equipped with CVTC (Continuously Variable-valve Timing Control). Bore and stroke are 85 mm and 69 mm, with a compression ratio of 9.8:1. It produces 173 PS (127 kW; 171 hp) @6000 rpm and 166 lb·ft (225 N·m) @4400 rpm.
