VQ25HR
Nissan updated the VQ line for 2007. The 2.5 L VQ25HR (for "High Revolution" or "High Response") is only available on rear wheel drive vehicles. It produces 225 PS (165 kW) @6800 rpm and 194 ft·lbf (263 Nm) @4800 rpm with a compression ratio of 10.6:1. It has CVTC, microfinished camshafts and redline of 7500 rpm. The intake is a high-flow tuned induction system.
VQ30DE
The 3.0 L (2,987 cc) VQ30DE produces 190 to 227 hp (142 to 169 kW) @6400 rpm and 205 to 217 ft·lbf (277 to 294 Nm) @4400 rpm. Bore and stroke are 93 mm and 73.3 mm with a compression ratio of 10.0:1.
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 relatively light weight. The VQ30DEK produces 222 hp (166 kW) and was made for the 2000-2001 Nissan Maxima.
The improved VQ30DE used from 2000-2001 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.
VQ35DE
The 3.5 L (3498 cc) VQ35DE is used in many modern Nissan vehicles. It uses the same block found in the VQ30DE, but adds variable valve timing. It has a bore of 95.5 mm and stroke of 81.4 mm. Output ranges from 240 hp to 306 hp (179 to 228 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 2007. It features forged steel connecting rods, a microfinished one-piece cast camshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum-coated pistons and the intake system is a high-flow tuned induction system.
A modified version of the VQ35DE, called the S1, is produced by Nismo (Nissan's motorpsorts and performance division) 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. The 350Z GT-S concept has a VQ35DE equipped with a switchable Novidem supercharger, producing around 377 hp (281 kW) with the supercharger switched on. The engine may possibly be referred to as the VQ35DER if the GT-S goes into production.
VQ35HR
Nissan updated the VQ line for 2007 with the addition of the 3.5 L VQ35HR (for "High Revolution" or "High Response"). It produces 315 PS or 311 hp (232 kW) @6800 rpm and 268 ft·lbf (358 Nm) @4800 rpm and compression ratio is 10.6:1. It has NDIS (Nissan Direct Ignition System) and CVTC with hydraulic actuation on the intake cam and electromagnetic on exhaust cam. Redline is 7500 rpm. The intake is a high-flow tuned induction system.
VQ37VHR
The VQ37VHR is a 3.7 L (3696 cc) engine with a higher compression ratio (11.0:1) than the VQ35HR. It is rated at 330 hp (246 kW) and 270 ft·lbf (366 Nm). Bore is 95.5 mm with 86 mm stroke. Although the engine only gains 2 ft·lbf of torque at peak, the torque curve itself is improved and flattened all around by as much as 15%. Redline remains 7500 rpm. It marks the first use of Nissan's VVEL (Variable Valve Event and Lift) system on a production vehicle.
