The Nissan VQ30DE is a 2,988 cc, 60-degree V6 naturally aspirated petrol engine produced between 1995 and 2004. It features an aluminium block and heads, dual overhead camshafts (DOHC), and 24 valves, forming part of Nissan's award-winning VQ engine family. Output varied by application, typically ranging from 147 kW (200 PS) to 157 kW (213 PS), with torque figures around 278–288 Nm, delivering smooth, linear power for refined drivability.
Fitted to premium and performance-oriented models like the Cefiro (A32/A33), Maxima (A32/A33), and Cedric/Gloria (Y34), the VQ30DE was engineered for quiet operation, strong mid-range torque, and reliability. Emissions compliance for its era was managed through sequential multi-port fuel injection and catalytic converters, meeting pre-Euro or early Euro 3 standards depending on the specific market and year.
One documented service concern is premature wear of the exhaust camshaft sprocket, which can cause timing chain noise or failure if not addressed. This issue, referenced in Nissan Technical Service Bulletins for the A33 platform, was linked to material or heat treatment inconsistencies in early production runs. Later engines saw revisions to the sprocket design and material to improve durability.
Production years 1995–2000 generally meet pre-Euro standards; 2001–2004 models meet early Euro 3 standards depending on market and specific vehicle application (VCA UK Type Approval data for relevant chassis codes).
The Nissan VQ30DE is a 2,988 cc 60-degree V6 naturally aspirated petrol engine engineered for sedans and coupes (1995-2004). It combines aluminium construction with a DOHC 24-valve valvetrain to deliver smooth, refined power and strong mid-range torque. Designed for pre-Euro/early Euro 3 compliance, it prioritises mechanical refinement and long-term durability.

The DOHC 24-valve design provides a broad, smooth powerband ideal for comfortable cruising and responsive acceleration. Regular oil changes using high-quality 5W-30 oil are critical to protect the timing chain and variable valve timing components. The exhaust cam sprocket wear issue on early engines necessitates listening for chain rattle on startup; if detected, prompt replacement of the sprocket and tensioner per Nissan TB-98-021 is advised. Fuel injectors should be cleaned periodically to maintain optimal spray patterns and fuel economy.
Oil Specs: Requires API SJ/SL specification oil for optimal protection (Nissan Owner's Manual A33/Y34). SAE 5W-30 is the typical recommendation for all-weather performance.
Emissions: Pre-Euro certification applies to most models; specific Euro 3 compliance for late models is chassis and market-dependent (VCA Type Approval Database).
Power Ratings: Measured under JIS D 1001 standards. Output varies by market and specific vehicle gearing (Nissan Group PT-2003).

The Nissan VQ30DE was used across Nissan's A32/A33/Y34 platforms with longitudinal mounting. This engine received platform-specific adaptations-different intake manifolds in the Cefiro versus the Maxima-with minor running changes throughout its production life. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the left-hand cylinder head, near the timing cover (Nissan SM-EC-95A33). The 8th VIN digit for A33/Y34 vehicles often corresponds to the engine type ('V' for VQ series). The VQ30DE is visually identified by its aluminium block, twin cam covers, and the intake manifold positioned between the cylinder banks. Critical differentiation from the VQ35DE: VQ30DE has a 3.0L displacement (93mm bore) vs. VQ35DE's 3.5L (95.5mm bore).
The VQ30DE's primary reliability risk is exhaust camshaft sprocket wear on early builds, with elevated incidence in high-mileage or poorly maintained engines. Nissan service data indicates this is a significant cause of timing-related repairs for pre-2000 engines, while its overall design ensures long service life with basic maintenance. Chain tensioner wear and fuel injector clogging are secondary concerns.
