The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching to a timing chain from a timing belt, and relocating the water pump from the outside of the engine to inside the timing cover where the pump is driven by the timing chain. Later versions featured various improvements, such as variable valve timing, and NEO-Di designated VQ engines replace MPFI with direct fuel injection.
The VQ series engine was honored in a record 14-straight selections by Ward's 10 Best Engines from the list's inception until 2008.[1]
1st gen (1994-)
The VQ20DE is an aluminium block, aluminium head, DOHC 24-valve 1995cc V6, with a NaNmm bore and stroke and compression ratio ranging from 9.5 to 10.0:1. In base form it produces 1500NaN0 to 1600NaN0 at 6400 rpm and 137to at 4400 rpm (lean burn).
It is fitted to the following vehicles:
The VQ23DE displaces 2.3 L (2349 cc) and is eqontinuously Variable-valve Timing Control). Bore and stroke are NaNmm, and compression ratio is 9.8:1. It produces 1730NaN0 at 6000 rpm and 166lbft at 4400 rpm.
It is fitted to the following vehicles:

The 2987cc VQ30DE has a bore and stroke of NaNmm respectively with a compression ratio of 10.0:1. It produces 1920NaN0 to 2300NaN0 at 6400 rpm and 205to at 4400 rpm. The VQ30DE was on the Ward's 10 Best Engines list from 1995 through 2001. It is an aluminium 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 2300NaN0). The VQ30DEK produces 2270NaN0. The 1995–1999 US spec VQ30DE was equipped with only a single runner intake manifold.
The 2987cc VQ30DET is a turbocharged version of the VQ30DE. Bore and stroke remain the same at NaNmm respectively, and it has a compression ratio of 9.0:1. It produces 2700NaN0 and 271lbft. From 1998 onwards, it produces 2800NaN0 at 6000 rpm and 285lbft at 3600 rpm.
It is fitted to the following vehicles:
The twin-turbo VQ30DETT is an engine used only in Nissan's race cars, primarily in the Super GT (formerly the JGTC). First used on the Skyline GT-R race cars during the 2002 season, this engine subsequently powered the Fairlady Z race cars. Homologation rules allow them to use the VQ30DETT in lieu of the stock VQ35DE. Race output of this engine is estimated at around 4800NaN0.
The VQ30DETT was replaced in 2007 by the VK45DE for use in the Super GT Fairlady Z's and later in the GT-R.
It was utilized in the following vehicles:
| VQ35DE | ||
|---|---|---|
| displacement | 3,498 cc | |

| produces torque (kgf⋅m) | 34.05 ~ 37.83 @ ????rpm | |
| produces torque (N⋅m) | 334 ~ 371 @ ????rpm |
The 3498cc VQ35DE is used in many modern Nissan vehicles. Bore and stroke are NaNmm. It uses a similar block design to the VQ30DE, but adds variable valve timing (CVTCS) for the intake. It produces from 231to of power and 246to of torque depending on the application.
The VQ35DE is built in Iwaki and Decherd, TN. It was on the Ward's 10 Best Engines list from 2002 through to 2007 and again in 2016.It features forged steel connecting rods, a microfinished one-piece forged crankshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum-coated pistons and the intake is a high-flow tuned induction system. Since its inception Nissan has improved upon the VQ35DE with changes keeping it an efficient class leading V6 engine. The engine was updated in 2005 as the VQ35DE Rev-Up. It included variable exhaust timing, a higher rev limit, and a revised oil pump, boosting the output to 297 crank horsepower. This motor was only found in the manual equipped 350z for the 2005-2006 and the manual equipped G35 2005 through 2007 model years.
A modified version of the VQ35DE, called the S1, is produced by Nismo (Nissan's motorsports and performance division) for the Fairlady Z S-Tune GT. It produces 3000NaN0 at 7,200 rpm, a higher rev-limit than that of the original VQ35DE.

The VQ35HR engine was first seen in the US with the introduction of the updated 2007 G35 Sedan model, which debuted in August 2006. Nissan updated the VQ line with the addition of the 3.5 L VQ35HR (for "High Revolution"). It produces 3150NaN0 (US market: 3060NaN0 using the revised SAE certified power benchmark) at 6,800 rpm and 370NaN0 at 4,800 rpm, using a compression ratio of 10.6:1. As of 2009, the Infiniti EX35 produces 2970NaN0 and the same torque presumably due to tighter regulations. It has NDIS (Nissan Direct Ignition System) and CVTC with hydraulic actuation on the intake cam and electromagnetic on the exhaust cam. Redline is 7,600 rpm. Reportedly over 80% of the internal components were redesigned or strengthened to handle an increased RPM range sporting a lofty 7,600 rpm redline. A new dual-path intake (two air cleaners, throttle bodies, etc.) lowers intake tract restriction by 18 percent and new equal-length exhaust manifolds lead into mufflers that are 25 percent more free-flowing for all around better airflow. The electrically actuated variable valve timing on the exhaust cams to broaden the torque curve is new over the "DE" engine. The new engine block retained the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to 7600 rpm. With an increase in compression ratio from 10.3:1 to 10.6:1 these changes add 6 more horsepower (306hp total + 3 hp ram air effect not measured by SAE testing = 309hp). Peak torque is up 8 pound-feet from the older "DE" engine, 260lbft vs 268lbft and the torque curve is higher and flatter across most of the rpm range, and especially in the lower rpm range. The VQ35HR was utilized in rear-wheel-drive platforms while the VQ35DE continued to power Nissan's front-wheel-drive vehicles. In 2010, Nissan introduced a hybrid version of the VQ35HR, pairing the engine to a lithium-ion battery pack.

By 2007, Nissan's ambition to increase the competitiveness of the Z33 chassis in Super Taikyu racing resulted in the development of a larger displacement engine based on the original VQ35HR Block. It featured the same bore but longer-throw crankshaft (bore × stroke: 95.5 mm × 88.4 mm). The end result was the VQ38HR powered Nismo Type 380RS-C which went on to dominate ST class 1 racing. The 3.8-liter racing engine in the 380RS-C develops maximum power of more than 2940NaN0, and maximum torque of 4210NaN0.[2] In order to use this new engine in Super GT GT500, limited numbers of the engine were reproduced in the street-legal Fairlady Z Nismo Type 380RS. The VQ38HR engine mounted in the 380RS is a detuned, street version of the racing engine used in the 380RS-C. The engine displacement remains the same, while the intake manifold and exhaust, air-fuel ratio, ignition timing, VTC and other specs have been optimized for street use. The engine produces maximum power of 2570NaN0 at 7200 rpm, and maximum torque of 3970NaN0 at 4800 rpm.[3]
The VQ38HR fitted to the following vehicles:
The VQ35HR and VQ25HR engines were built at Nissan's Iwaki Plant in Fukushima Prefecture.[4] [5]
The VHR series is a variation of the VQ-HR engine series with Nissan's VVEL (Variable Valve Event and Lift).

It was the first production engine from Nissan using VVEL.
It has a compression ratio of 11.0:1, with a displacement of 3696cc, thanks to a bore x stroke of NaNmm and a redline of 7,500 rpm.
It is rated at 3320NaN0 at 7,000 rpm and of torque at 5,200 rpm, and up to 3500NaN0 at 7,400 rpm and of torque at 5,200 rpm.
Although the engine VQ37VHR gains only and in the Nissan 370Z Nismo, torque over the VQ35HR and this higher torque arrives at 5,200 rpm vs 4,800 rpm in the VQ35HR, the torque curve itself is improved and flattened via VVEL variable valve timing for better throttle response and low rpm torque.
