VQ35DE: Everything You Want to Know | Specs and More

The VQ35DE is one of Nissan’s greatest modern achievements, which ultimately led to the VQ37. The main reason that the VQ35DE was such a great accomplishment is due to its versatility. It made an impressive 300 horsepower, whilst retaining 22+ mile per gallon. The JDM community praises the VQ35DE, but is it really that good?

VQ35DE: Engine Basics

Before we get into why the VQ35DE is so awesome, let’s cover the basics of the engine:

The VQ35DE is a 3.5L V6 that replaced the VQ30DE found in the Nissan Maxima from 1995 to 2001. Nissan achieved such high horsepower per liter using dual overhead camshafts, and 4 valves per cylinder.

Not too surprisingly, the VQ35DE features aluminum cylinder heads and an aluminum cylinder block. This helps keep weight down, which is important for balance in a sports car. You really don’t want a heavy engine on the nose of your car when handling is important.

All VQ35DE engines feature Nissan’s variable valve timing system (CVTCS). This further improves power and decreases fuel consumption.

  • Production: 2000 – present
  • Cylinder Block Material: Aluminum
  • Cylinder Head Material: Aluminum
  • Valve train: DOHC, 4 valves per cylinder
  • Stroke: 81.4mm
  • Bore: 95.5mm
  • Compression Ratio: 10:1 – 10.5:1
  • Displacement: 3498cc
  • Redline: 6,500 – 7,000 rpm (Rev-up version)

As you can tell, Nissan stuffed the VQ35DE in just about every product they’ve had over the last 15 years. If that’s not a testament to its versatility, then I don’t know what is.

VQ35DE: Performance Data

The performance data for the VQ35DE can be a little hard to understand online. This is because throughout the many vehicles it came in, and the different versions of the engine itself. Luckily the folks at Wikipedia have made the performance data very easy to understand.
Additional VQ35DE information is available on Wikipedia.

North American market:

  • 2001–2004 Nissan Pathfinder: 240 hp
  • 2013–2016 Nissan Pathfinder: 260 hp
  • 2001–2004 Infiniti QX4: 240 hp
  • 2002–2004 Infiniti I35: 255 hp
  • 2002–2016 Nissan Altima: 240 hp – 270 hp
  • 2002–2016 Nissan Maxima: 255 hp – 300 hp
  • 2003–2006 Nissan 350Z: 287 hp – 300 hp
  • 2003–2007 Infiniti G35 Coupe: 280 hp – 298 hp

  • 2006–2008 Infiniti M35: 275 hp – 280 hp
  • 2013–2013 Infiniti JX35: 265 hp
  • 2014–2016 Infiniti QX60: 265 hp

Rev-up vs. standard:

The 2003 – 2004 350Z wasn’t the “rev-up” version of the VQ35 engine and produced 287 horsepower. The 2005-2006 350Z were “rev-up” engines, and produced 300 horsepower. The Rev-up engine produced more horsepower by adding variable valve timing to the exhaust camshaft. Also added was a different ECU, slightly different internals, and a different intake plenum. All of this added up to the 300 horsepower that it produced.

VQ35DE: Tuning Potential

As a car guy, this is the part I find interesting. Although the VQ35 is an interesting engine in stock form, we find modified engines more interesting. One of the quickest ways to see how powerful a VQ35DE can be is to look at Nissan’s race cars.

The Dallara T12 which races in the World Series by Renault uses a VQ35 engine inside of it. The Dallara T12 makes an absolutely insane naturally aspirated 480 horsepower from the VQ35 that powers it. The VQ35DE is also in many other Dallara race cars, all of which are equally insane as the Dallara T12.

Enough about the race cars already let’s hear about street cars! Some people will build a naturally aspirated VQ35. Some naturally aspirated builds can reach as much as 400whp. But, that takes an insane amount of time and money. The average tuner would rather boost their VQ35 because the performance per dollar is so much better.

Unfortunately, the VQ35DE is limited to about 400whp due to weak connecting rods. However, with a built internals the stock block can take 700whp or more if you’re crazy enough.

VQ35DE: Known Problems

Just like any other engine in the world, the VQ35DE does have some issues. The Rev-up version, in particular, is known for excessive oil consumption. This issue does affect the standard VQ35 as well, but not nearly as often. Many owners complain of a loud rattling noise on startup which is typically the factory timing chain tensioner. The tensioner is known for not being the best quality and can cause major engine damage if ignored for to long. The poor tensioner can cause excessive timimg chain wear causing it to fail prematurely.

Summary

So the VQ35DE is an incredibly versatile, and reliable little engine. Nissan stuffed it into many of their products over the last 15 years. Not only can it make excellent power, but its fuel efficient, and extremely reliable. It also has pretty good tuning potential.

The reason people don’t talk about the VQ35 is the high cost for an N/A build. A Chevy LS swap is cheaper and has more potential for high horsepower. Basically, Chevy LS swaps have forced the VQ35 into the shadows. This dropping cost of a used 350Z, however, is changing this issue.

  1. On VQ35HR there are no problems with the couplings, my motor (already now), the motor ran 107,000 km (further sold), I did not have any problems with them, well, in general, in 4 years of communication with other owners, I did not hear that on the 350Z, Then I suffered with couplings.

  2. Need help with an engine swap having problems finding a VQ35de rev up motor. I found one out of a 10/05 skyline will it fit strains into a 350z or is there different wiring and pollution
