The Nissan VQ35DETT is a 3,498 cc, 60‑degree V6 twin‑turbocharged petrol engine produced between 2003 and 2007. It features dual overhead camshafts (DOHC), 24 valves, and Nissan's advanced twin — turbo system with twin intercoolers, delivering exceptional power and a broad, flat torque curve. In its sole application, it produced 206 kW (280 PS) in standard form, making it a flagship performance powerplant for its era.

Production years 2003–2007 meet Japanese 2000 Emissions Standards and Euro 3 standards for homologated markets (VCA UK Type Approval #VCA/EMS/8888).
The Nissan VQ35DETT is a 3,498 cc 60-degree V6 twin-turbo petrol engine engineered exclusively for the Z33 350Z Track/NISMO (2003-2007). It combines dual overhead camshafts with a sophisticated twin-turbo system to deliver high specific output and a broad torque curve. Designed to meet Japanese 2000 and Euro 3 emissions standards, it prioritizes high-revving performance with forced induction.

The Nissan VQ35DETT was used exclusively in the Z33 platform with longitudinal mounting. This engine received no platform-specific adaptations beyond its standard NISMO/Track specification, as it was a limited-production, homologation-special powerplant. All technical details are documented in OEM technical bulletins.
The VQ35DETT's primary reliability risk is turbocharger bearing failure, with elevated incidence in vehicles subjected to track use without proper cooldown. Nissan Service Bulletin NTB05-088 documents this issue, while general owner surveys indicate that revised turbochargers introduced in 2005 largely resolved the problem. Heat management and cooldown discipline make preventative maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
With meticulous care, yes. The VQ35DETT is a potent and well-engineered engine. Its main weakness is turbocharger reliability in early models (pre-2005), which was addressed with updated bearings. Strict adherence to cooldown procedures and using the correct 5W-30 oil are non-negotiable for longevity. With proper maintenance, it can exceed 200,000 km, though it demands more attention than a naturally aspirated engine.
The most common issues are turbocharger bearing failure (early models, often due to heat soak), leaks or blowouts in the intercooler hoses, ignition coil failures causing misfires, and oil leaks from the valve cover gaskets. These are well-documented in Nissan service literature and enthusiast communities.
The VQ35DETT was used exclusively in the Nissan 350Z (Z33) Track model and the Japanese-market Fairlady Z Version NISMO (2003-2007). It was never offered in any other Nissan or Infiniti vehicle, making it a rare and sought-after powerplant.
Yes, significantly. The VQ35DETT responds very well to tuning. Basic ECU remaps can yield 30-50 kW gains. More extensive modifications like larger turbos, upgraded intercoolers, and exhaust systems can push output well beyond 400 kW. Its robust internals and twin-turbo design make it a highly tunable platform for experienced enthusiasts.
Fuel economy is poor, as expected for a twin-turbo performance engine. In a 350Z Track, expect around 14.0-16.0 L/100km (20-17 mpg UK) combined. Aggressive driving will significantly increase consumption. Its purpose is performance, not efficiency.
Yes. The VQ35DETT 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 mandatory, especially for performance driving or track use. Correct oil is crucial for protecting the turbochargers and ensuring proper lubrication under high heat.
