What Makes Nissan's VQ35de Engine so Efficient?


Nissan's vq35de engine is known for its incredible performance and reliability. This engine is found in many Nissan vehicles, including the 350z and G35. The vq35de engine is a 3.5-liter V6 that was first introduced in 2001. Since then, it has undergone several improvements making it even more efficient and powerful. But what exactly makes this engine so efficient? In this blog post, we'll explore the key factors that make the vq35de engine stand out from the crowd.


Variable Valve Timing (VVT)


The vq35de engine uses Nissan's advanced VVT system. This system adjusts the timing of the engine's intake and exhaust valves to match the engine's RPM and load. At low RPMs, the VVT system keeps the valves open for longer periods to improve low-end torque. At higher RPMs, the system adjusts the timing of the valves to allow for more efficient airflow, resulting in increased high-end power output.


Lightweight Components


The vq35de engine is designed with lightweight components to reduce the engine's overall weight. The engine block and cylinder heads are made from aluminum, which not only reduces weight but also helps improve heat dissipation. Other components, such as the pistons and con rods, are also made from lightweight materials to help reduce rotational mass and improve throttle response.


Advanced Direct Injection


The vq35de engine is equipped with advanced direct injection technology, which delivers fuel directly into the combustion chamber at high pressure. This results in improved fuel efficiency and reduced exhaust emissions compared to traditional port injection systems. The direct injection system also allows for a higher compression ratio, which improves power output.


High-Flow Exhaust System


The vq35de engine features a high-flow exhaust system that helps improve engine breathing and scavenging. A high-flow exhaust system allows for more efficient airflow, resulting in increased power output and improved fuel efficiency. The system also produces a distinctive exhaust note that is enjoyed by many Nissan enthusiasts.


Well-Matched Transmission


The vq35de engine is typically paired with a well-matched transmission that enhances the engine's performance. Nissan's six-speed manual transmission, for example, provides smooth and precise shifts, along with a short-throw shifter that improves gear change speed. The engine's power and torque are also well-matched to Nissan's five-speed automatic transmission, which provides smooth and responsive gear changes.



The vq35de engine's advanced technology, lightweight components, direct injection system, high-flow exhaust, and well-matched transmission are all key factors that contribute to its efficiency and performance. These features make this engine an excellent choice for those who want a reliable, efficient, and powerful engine for their Nissan vehicle. Whether you're looking for a sports car or a sedan, the vq35de engine is sure to impress. Check out our stock of VQ35 engines!
