The VQ35DE is a 3.5L engine that was first introduced in the Nissan 350Z and Infiniti G35. It is an evolution of the VK45DE, which was used in the Infiniti Q45 and Nissan Armada beginning in 1995. The VQ35DE shares many parts with its predecessor, but has been updated to make it more reliable and less prone to failure.
The heart of this engine is its aluminum block, which comes with cast-iron cylinder liners that are sealed with an aluminum gasket to prevent oil from leaking out. The block also features cross-bolted main bearing caps that increase stiffness and reduce vibration, as well as aluminum heads with iron cylinder liners for added durability.
The VQ35DE can be built using either forged steel or cast pistons, depending on what kind of performance you’re looking for from your build. Forged pistons are generally preferred because they have higher thermal conductivity than cast pistons do, which means they transfer heat better so you can get more power out of them without frying your engine.
The VQ35DE is a 3.5-liter engine that was first produced by Nissan in 2006. It has since been used in various vehicles, including the Infiniti G35, Nissan 350Z and 370Z, and Ford Mustang GT.
The engine is a V6 with four camshafts and 24 valves. It features a dual overhead cam per cylinder head design with hydraulic lifters on the intake side and solid tappets on the exhaust side. The intake valves are 30 mm in diameter and the exhaust valves are 28 mm in diameter.
The VQ35DE is considered to be a high-revving engine due to its high compression ratio of 11:1, which allows it to achieve an output of 276 horsepower at 6200 pm and 266 pound-feet of torque at 4800 rpm when running on premium fuel.
Building a VQ35DE is something that can be done by a novice mechanic, but it requires some patience and attention to detail.
The first step is to make sure you have all of the necessary parts. If you don’t have them, buy them now so that you can get started on the project as soon as possible.
Once you have everything ready to go, remove the air filter box and then remove the cover over the power steering pump. This will allow you access to the engine mounting bolts that hold down your engine block. Remove these bolts and set them aside in a safe place where they won’t get lost or damaged while working on your car’s engine.
Next, loosen up all of the nuts holding down your exhaust manifold with a socket wrench so that they can be removed easily later on when installing new components like pistons or connecting rods into place once they’ve been properly aligned within their respective cylinders inside this part of your vehicle’s engine block itself (which should be done during this stage).
Now remove all four spark plugs from their respective locations at either end of each cylinder head using an extension bar (or other tools) attached to an impact wrench (you’ll need one if your hands aren’t strong enough otherwise): one from each cylinder head side.
To build a VQ35DE engine, you’ll need to buy the right parts and labor to get the job done. Some VQ35DE parts cost $100 and others run upwards of $400. The labor costs will depend on your location and the year of your engine.
Oil dripping onto hot components
The VQ35DE is a 3.5L V6 engine from Nissan that started production in 2000. It’s best known for its use in the 350Z and G35, and it offers a solid mix of reliability and longevity. In this article, we’ll talk about some of the more common problems associated with this engine, as well as how to fix them for long-term engine health.
The first symptom of an oil leak on a VQ35DE is an oil leak that is visible on the ground. It might be a small leak at first, which you may be able to notice because of how the oil smells and how it looks. Secondly, you may start to smell burning oil and even notice a small amount of smoke.
Aluminum cylinder heads
Changing the cylinder heads is an important step in rebuilding a VQ35DE. This part is relatively inexpensive but can require moderately intensive labor. The labor cost can range from $500 to $800 depending on your location and the year you’re building your VQ35DE. If you’re not comfortable with DIY work, you can purchase an assembled CNC-ported aftermarket head for under $2000.
Another common component that can cause problems with your VQ35DE engine is the valve cover gasket. A new valve cover gasket can cost anywhere from $10 to $20. If you’re using a manual transmission, you may also encounter problems with the clutch slave cylinder. If this happens, it’s likely time to replace the clutch slave cylinder. However, a VQ35DE is a very reliable engine, fuel-efficient, and offers great tuning potential. While it can be expensive to build a VQ35DE, it’s worth considering the cost of an LS swap.
Another consideration when building an LS engine is how much aluminum cylinder heads will cost. For high-horsepower engines, you may want to consider buying billet aluminum heads. These head kits are made of solid billet aluminum. The material is then removed until only the cylinder head is left. These heads are a bit more expensive than cast aluminum heads, but are extremely strong and look great.
Another upgrade that will increase horsepower is an intake plenum spacer. It creates a large space between the throttle body and the intake runners. This will make the intake flow more evenly throughout the cylinders. This modification usually adds about 10-20 horsepower. These parts are not difficult to install and are often used by DIY builders to improve their VQ35DE’s performance.
Variable valve timing system
Variable valve timing (VVT) is a technology that allows automakers to control the valve timing for each cylinder individually. It is a complex system that uses a combination of hydraulic and mechanical components to control valve opening and closing. This technology helps the engine respond quickly to changes in engine conditions and improves fuel efficiency. The technology is currently used in the top three Japanese car manufacturers, including Honda and Toyota.
While this system is more expensive than a traditional engine, it has proven to be a reliable and efficient system. It can increase fuel economy, power, and emissions. It also allows carmakers to build a more powerful engine. If you’re interested in learning more about this technology, take a look at the costs involved and what benefits it provides.
Variable valve timing systems can be expensive to repair. For starters, replacing a solenoid can cost as much as $131 to $168. But the more advanced versions may cost you more than $168. In addition to the high cost, you need to consider the amount of labor that will be required.
The most common issue with a VVT is a faulty solenoid. Typically, these systems can cost between $400 and $1300 to fix. In addition, they may require costly modifications to the engine to get optimal performance. For example, if an engine operates at 3000 RPM, the camshaft rotates about 25 times per second.
Stage 6 long block
If you’re in the market for a new VQ engine, the Stage 6 Long Block is an excellent choice. This engine is ideal for Nissan 350Z or Infiniti G35 owners looking to add more power. It comes with a full warranty and has a proven track record for reliability. It also comes with more than ten years of building Nissan/Infiniti motors, so you can rest assured that you’ll be getting a quality performance.
One of the most popular modifications for the VQ35DE is the intake plenum spacer. It creates a large volume between the throttle body and intake runners, ensuring equal airflow through each runner. This modification can add anywhere from 10 to 20 horsepower to your engine, and it’s fairly simple to install.
The VQ35DE is a reliable, fuel-efficient engine that can be used for many purposes. It can be used to power cars and light trucks and is even used in SUVs and people carriers. However, it can be expensive to build a Stage 6 long block, and the VQ35DE is no exception. The Chevy LS swap is far cheaper and can give you the same high horsepower potential.
Intake plenum spacer
An intake plenum spacer is a simple modification that can significantly increase the horsepower and torque of your VQ35DE. It works by increasing the volume of the plenum chamber and distributing the air evenly among the cylinders. It is a simple and cost-effective way to boost performance without breaking the bank.
Intake plenum spacers can give your VQ35DE up to 14 BHP and can significantly increase your gas mileage. For just a few hundred dollars, these mods are a great way to make your 350z perform better. They will also increase the overall performance of your vehicle and give you more control over its power.
You can choose from two types of intake plenum spacers: the aluminum spacer and the thermo-polymer spacer. The former is more durable and more thermally efficient. You can also choose between different thicknesses and sizes. This modification is the best way to increase your car’s power and torque. It will also help you achieve greater throttle response.
The BLOX Racing plenum spacer has a thermal-polymer material that is durable and inexpensive. It also gives you more power and torque at high RPM, while also improving engine tone. Motordyne’s Basic plenum spacer is another popular option and can increase top-end power and torque. It also comes with a pre-attached plenum gasket, making installation simple.
