VQ35DE: Everything You Want to Know
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 VQ35DE is heavily praised amongst the JDM community, but is it really that good?
VQ35DE: Engine Basics
Before we get into why the VQ35DE may or may not be as good as it’s made out to be, we must first cover the basics:
The VQ35DE is a 3.5L V6 that replaced the VQ30DE found in the Nissan Maxima from 1995 to 2001. One of the ways that Nissan achieved such high horsepower per liter is through dual overhead camshafts, and 4 valves per cylinder.
Not to 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.

Cars That Came With The VQ35DE
Since the VQ35DE was an extremely versatile engine with its good horsepower and low fuel consumption, it ended up in a many different Nissan products.
The VQ35DE is currently available in these North American models:
- Infiniti QX60 (since 2014)
- Nissan Altima (since 2002)
- Nissan Maxima (since 2002)

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 different 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.

Rev-up vs. standard:
The 2003 – 2004 350Z were the non “rev-up” 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, 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’m actually interested in. I don’t care what the VQ35DE is like stock, I want to know what it can do when modification is involved. One of the quickest ways to get a feel for how crazy a VQ35DE can actually be, is to look at some of Nissan’s race cars.
The Dallara T12 which races in the World Series by Renault, is essentially a Formula race car chassis, with a VQ35 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 numerous other Dallara race cars, all of which are equally insane as the Dallara T12.
Enough about the race cars already, lets hear about street cars! The crazy street drivers with deep pockets can build a naturally aspirated VQ35 that makes just as much power as the previously mentioned race cars. But, that takes an insane amount of money, time, and enguiniety. The average tuner would much rather boost their VQ35.
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.
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.
So, why don’t more people talk about this engine? Well, as far as engine swaps are concerned its more cost effective to go with an LS V8, so the VQ35DE it kind of stuck in its shadow.
