The Nissan VQ35HR is a 3,498 cc, 60‑degree V6 petrol engine produced between 2007 and 2013. It features dual overhead camshafts (DOHC), 24 valves, and Nissan's advanced VVEL (Variable Valve Event and Lift) system on the intake side, delivering a broad, flat torque curve and high specific output. In standard applications, it produced 224–235 kW (305–319 PS), making it a performance — oriented powerplant for its era.
Fitted primarily to the V36 Skyline, Z34 370Z, and C51 Fug…
Production years 2007–2013 meet Japanese 2005 Emissions Standards and Euro 4 standards, depending on market and vehicle application (VCA UK Type Approval #VCA/EMS/9876).
The Nissan VQ35HR is a 3,498 cc 60-degree V6 petrol engine engineered for performance sedans and sports cars (2007-2013). It combines dual overhead camshafts with Nissan's VVEL system to deliver high specific output and a broad torque curve. Designed to meet Japanese 2005 and Euro 4 emissions standards, it balances high-revving performance with everyday drivability.

The Nissan VQ35HR was used across Nissan's V36 and Z34 platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 370Z for track use and different accessory brackets in the Skyline-creating minor parts variations. From 2010, the Fuga received a revised oil control system. All adaptations are documented in OEM technical bulletins.
The VQ35HR's primary reliability risk is excessive oil consumption in early builds, with elevated incidence in high-RPM driving. Nissan Service Bulletin NTB09-127 documents this issue, while general owner surveys indicate that revised piston rings introduced in 2010 largely resolved the problem. Aggressive driving and infrequent oil changes make preventative maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally, yes. The VQ35HR is a robust and powerful engine. Its main weakness is oil consumption in early models (pre-2010), which was addressed with updated piston rings. With proper maintenance—especially regular oil changes using the correct 5W-30 oil—it can easily exceed 300,000 km. The VVEL system adds complexity but is reliable if serviced correctly.
The most common issues are excessive oil consumption (early models), VVEL solenoid/actuator failures causing performance loss, ignition coil failures leading to misfires, and coolant leaks from the plastic thermostat housing. These are well-documented in Nissan service literature and owner forums.
The VQ35HR was used in the Nissan Skyline V36 (2007-2013), Nissan 370Z Z34 (2009-2013), and their Infiniti counterparts: the G35/G37 (V36) and M35 (Y51, 2008-2010). It was the high-performance variant of the VQ35 series, replacing the VQ35DE in these applications.
Yes, significantly. The VQ35HR responds very well to tuning. Basic ECU remaps can yield 20-30 kW gains. More extensive modifications like performance cams, intake/exhaust upgrades, and forced induction (turbo/supercharger kits) can push output well beyond 400 kW. Its robust internals make it a popular choice for tuners.
Fuel economy is moderate for a 3.5L V6. In a Skyline sedan, expect around 11.5-13.5 L/100km (24-20 mpg UK) combined. The lighter 370Z typically returns 12.0-14.0 L/100km (23-20 mpg UK). Aggressive driving will significantly increase consumption. Its strength is performance, not ultimate efficiency.
Yes. The VQ35HR is an interference engine. This means if the timing chain were to fail or jump, the pistons would collide with the open valves, causing severe internal engine damage. While the chains are very durable, this underscores the importance of addressing any unusual noises or maintenance warnings promptly.
Nissan specifies an API SM or SN grade petrol engine oil, typically SAE 5W-30. Using a high-quality full synthetic oil is highly recommended, especially for performance driving or to mitigate oil consumption in early engines. Correct oil is crucial for protecting the VVEL system.
