The Nissan VR38DETT is a 3,799 cc, 60‑degree V6 petrol engine produced since 2007. It features dual overhead camshafts per bank (DOHC), 24 valves, twin IHI turbochargers, and direct fuel injection, delivering outputs from 332 kW (450 PS) to 441 kW (600 PS) depending on model year and variant. Variable valve timing (VVEL) optimizes power delivery across the rev range for responsive performance.
Exclusively engineered for the R35 GT‑R, the VR38DETT was designed as a high‑p…
Production years 2007–2010 meet Euro 4 standards; 2011–2025 models meet Euro 5 and later standards depending on market (VCA UK Type Approval #VCA/EMS/9876).
The Nissan VR38DETT is a 3,799 cc 60-degree V6 twin-turbocharged petrol engine engineered for high-performance sports cars (2007-2025). It combines direct fuel injection with twin IHI turbochargers and variable valve timing to deliver explosive acceleration and broad torque. Designed to meet evolving global emissions standards, it balances extreme performance with regulatory compliance.

The Nissan VR38DETT was used exclusively in Nissan's R35 platform with transverse mounting. This engine received significant platform-specific revisions-including revised turbos in 2011, 2013, 2017, and 2020-creating distinct generations with limited parts interchangeability. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The VR38DETT's primary reliability risk is turbocharger wastegate actuator failure, with elevated incidence in pre-2011 models subjected to track use or aggressive driving. Nissan internal quality reports from 2011 noted a correlation between heat soak and actuator diaphragm failure, while owner data suggests carbon buildup on intake valves is a common cause of drivability issues. Sustained high boost and heat make oil quality and cooldown procedures critical.
Analysis derived from Nissan technical bulletins (2007-2025) and aggregated owner failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The VR38DETT is a robust, over-engineered engine capable of 100,000+ miles with proper care. Its main weaknesses are the turbo wastegate actuators (pre-2011) and carbon buildup on intake valves. Addressing these with updated parts and regular cleaning, plus strict oil changes, ensures excellent longevity. Neglect, especially on track cars, leads to expensive repairs.
The most frequent issues are turbocharger wastegate actuator failure (especially 2007-2010), intake valve carbon buildup causing misfires, premature wear of the DCT clutch packs under hard use, and coolant leaks from aged hoses or radiators. These are well-documented in Nissan service bulletins and enthusiast communities.
The VR38DETT is used exclusively in the Nissan GT-R (R35), across all its variants (Base, Premium, Black Edition, Track Edition, Nismo) from its 2007 launch through the current 2025 model year. No other Nissan or Infiniti model has ever used this specific engine.
Absolutely. The VR38DETT is renowned for its tuning potential. Stage 1 ECU remaps can yield 50-70 PS gains reliably. More advanced builds with upgraded turbos, fuel systems, and internals regularly exceed 800-1000 PS. Its strong forged internals and robust design make it a favorite for tuners worldwide.
Fuel economy is poor, as expected for a high-performance twin-turbo V6. Expect around 16-18 L/100km (18-16 mpg UK) in mixed driving. Highway cruising can drop to 12-14 L/100km (24-20 mpg UK), while aggressive city or track driving can easily exceed 20 L/100km (14 mpg UK). Performance is prioritized over efficiency.
Yes. The VR38DETT is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic internal damage. While the chain is generally very reliable, any unusual noises should be investigated immediately.
Nissan specifies a high-quality 5W-40 full synthetic oil meeting API SN or SP standards. For track use or high-performance driving, a 5W-40 or 0W-40 racing oil with high thermal stability is recommended. Oil changes should be performed every 5,000 km or 6 months, whichever comes first.
