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‑performance, track‑capable powerplant while maintaining daily drivability. Emissions compliance for global markets was achieved through precise direct injection, dual‑stage catalytic converters, and sophisticated engine management, meeting Euro 5 standards from 2011 and evolving to meet stricter regulations.
One documented reliability concern involves premature turbocharger wastegate actuator failure, particularly in early production models (2007–2010), as noted in Nissan Service Bulletin NTB‑10‑087. This issue, often linked to heat cycling and material fatigue, was addressed in 2011 with a revised actuator design featuring improved heat shielding and more robust internal components.
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 twin-turbo setup provides immense, linear power ideal for track use but demands strict 5,000 km oil changes with high-quality 5W-40 to protect turbos and bearings. The direct injection system is prone to intake valve carbon buildup; periodic walnut blasting is recommended. Early models (2007-2010) should have wastegate actuators inspected per NTB-10-087. The high 10.0:1 compression ratio requires premium 98 RON fuel for optimal performance and knock prevention. Coolant and transmission fluid should be changed per severe-duty schedule if used for track days.
Oil Specs: Requires 5W-40 synthetic oil meeting API SN/SP specification (Nissan Owner's Manual 2023).
Emissions: Euro 4 certification applies to 2007-2010 models; Euro 5 and later for 2011+ (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under JIS D 1001 standards. Peak figures vary by model year and market (Nissan TIS Doc. VR38-010).

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.
Locate the engine code stamped on the front timing cover, near the crankshaft pulley (Nissan TIS VR38-001). The 8th VIN digit for all R35 GT-R models is 'V'. Visually, the engine is identifiable by its twin IHI turbochargers mounted within the 'V' of the engine and the prominent front-mounted intercooler. Critical differentiation between model years: 2007-2010 engines have silver valve covers and earlier ECU calibration; 2011+ feature black valve covers, revised turbos, and updated engine management. Turbocharger assemblies are specific to model year ranges and are not interchangeable without ECU remapping.
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.
