Is the VQ35DE Weight Actually That Bad?
If you're arranging a project car or just trying to puzzle out if your Z is a bit of the pig, the vq35de weight is probably one associated with the first things started looking up. It's the coronary heart of the 350Z, the G35, and plenty of Maximas and Muranos, but when considering motor swaps, every pound matters. Normally, a dry VQ35DE long block weighs in at regarding 313 to 330 pounds (roughly 142 to a hundred and fifty kg). That's not really too shabby with regard to a 3. 5l V6, especially whenever you consider some of the iron-block dinosaurs people used to swap into little cars.
But here's the issue: "dry weight" is a bit of a lie we all tell ourself. Nobody drives around with a dry engine. Once you start bolting upon the alternator, the power steering pump, the particular AC compressor, and filling it along with oil and coolant, that number begins creeping up toward the 450-pound mark pretty quickly. Still, to have an engine that will can reliably push out 300 hp with just a couple bolt-ons, it's a good power-to-weight contender.
Smashing Down the Quantities
When we talk about the vq35de weight , we have to be particular about what's actually being measured. If you buy a "long block" from a junkyard, you're usually obtaining the block, mind, and maybe the particular valve covers. In that state, it's quite manageable. Two guys can move it around if they've been hitting the particular gym, though I'd definitely recommend the proper engine hoist if you benefit your lower back.
The reason the particular VQ35DE is relatively light compared to older Nissan engines like the RB25 or RB26 is its all-aluminum design. Nissan moved away from the heavy solid iron blocks of the 90s to save on fuel economy and improve dealing with. By using a good aluminum block with cast-iron cylinder liners, they got the very best of both sides: the heat waste and weight savings of aluminum along with the durability of iron in which the pistons actually do their own work.
If you're comparing this to a modern four-cylinder, yeah, it's likely to feel heavy. A Honda K24 is going to be about eighty to 100 pounds lighter. But if you compare this to a Ford or Chevy small-block V8 from the past, the VQ appears to be a featherweight. Even compared in order to the VR38DETT present in the R35 GT-R, the VQ35DE is much easier to package and toss into a lightweight chassis like an S13 or an 86.
Why the particular VQ35DE Weight Matters for Swaps
So, why perform people obsess over the vq35de weight so much? It usually comes lower to weight distribution. If you're falling this engine into a car that initially came with the four-cylinder, you're incorporating weight over the front wheels. This particular can lead in order to understeer, which will be the last thing you need if you're creating a drift vehicle or perhaps a grip-focused track toy.
The particular cool thing regarding the VQ is usually that it's quite compact. Because it's a 60-degree V-6, it sits fairly low and far back in the particular engine bay if you mount it correctly. In the Nissan 240SX, with regard to example, a VQ35DE swap actually keeps the weight submission fairly like the authentic KA24DE setup, specifically because you're dropping the heavy turbocharged setup that many people add to four-cylinders.
Another issue to keep in mind is the tranny. The VQ usually gets paired with the CD009 6 spedd manual. While the motor itself is affordable, that transmission is a tank. It's incredibly strong, however it adds a substantial quantity of weight in order to the overall driveline package. When people estimate their total "swap weight, " they will often forget that this gearbox is just as important since the block by itself.
Comparing the DE to Various other VQ Variants
It's also worth looking at how the vq35de weight stacks facing the younger brothers, such as the VQ35HR or maybe the VQ37VHR. You'd think they'd be the particular same since they're all V6s, ideal? Not exactly.
The HR (High Response) and the 3. 7-liter versions actually gained the little bit of weight. Nissan reinforced the block, additional a structural essential oil pan, and went to a dual-intake system. All those extra bits add up. The VQ35DE is often seen as the "simplest" and lightest of the particular bunch, which is why it continues to be so popular with regard to budget-conscious builders. This doesn't have the fancy dual-throttle body or the complex VVEL system found in the 370Z engine, which keeps the physical footprint and the weight slightly lower.
Waxing Weight Off Your VQ35DE
If you're worried that this vq35de weight is definitely going to destroy your car's balance, there are plenty of ways in order to trim body fat. One particular of the easiest places to start is the intake plenum. The share upper plenum is a chunky piece associated with cast aluminum. Changing to some plastic consumption manifold (from several of the newer front-wheel-drive VQ models) or a light-weight aftermarket spacer set up can save a few pounds up high, which helps reduce the center associated with gravity.
Exhaust system manifolds are another big one. The factory cast-iron manifolds are heavy and restrictive. Swapping individuals out for stainless steel headers not only the actual engine audio like a shouting banshee but additionally drops about 10 to 15 lbs right off the particular sides of the particular block.
Then you've got the particular accessories. If you're building a dedicated monitor car, do you really need that will AC compressor? Tugging the AC and the power steering (if you're going along with a manual rack or electric setup) can strip another 30-40 pounds away from the front from the engine. Every little counts when you're trying to create a car sense nimble.
The Reality of "Ready to Run" Weight
When you see several like 313 lbs for the vq35de weight , just remember that's the "naked" edition. Within the real globe, you have to account for: - Flywheel and Clutch: An investment dual-mass flywheel is incredibly weighty (nearly 30 lbs). Swapping to the lightweight chromoly flywheel can save fifteen lbs instantly. -- Liquids: Five or six quarts of oil plus a couple of gallons of coolant add about 20-25 pounds. - Wiring and ECU: Not a ton associated with weight, however it almost all adds up in the total package. - Brackets and Brackets: Steel motor mounts are heavier than you think.
If you're carrying out a swap, expect the entire weight boost over the standard inline-four to become around 100 to 150 pounds once everything is usually connected and operating. For several, that's a small price in order to pay for the particular instant torque and the reliability that the 3. 5-liter V-6 provides.
Could it be Worth It?
At the end of the day, the vq35de weight is one from the most powerful selling points in the V6 world. It's lighter than the iron-block V6s from the past and even more compact than several of its competition. It offers a great middle ground for those who want more energy than a four-cylinder nevertheless don't want the particular bulk and complexness of an OF V8 swap.
Whether you're trying to shave tenths away from your lap time or just interested in what's under the hood of your Nissan, knowing the weight gives you a much better perspective on just how the vehicle handles and reacts. It's the well-engineered piece of machinery that amounts strength and weight better than a lot of people give it credit score for. Sure, it's got its quirks (like the infamous oil consumption upon early models), but in terms associated with physical mass, it's a pretty efficient way to obtain 300 horses below your hood.
So, don't let the numbers frighten you off. The particular VQ35DE is the versatile, relatively light, and extremely capable engine. Just maybe make use of a hoist when you're moving this around—your back will certainly thank you later on.
