The Nissan VG30E is a 2,960 cc, 60‑degree V6 petrol engine produced between 1984 and 1995. It features a cast iron block, aluminium cylinder heads, SOHC valvetrain with 12 valves total, and electronic fuel injection. This naturally aspirated powerplant delivered 115–120 kW (156–163 PS) and 226–244 Nm of torque, prioritizing smooth, linear power delivery for comfortable cruising.
Fitted to models such as the 300ZX (Z31), Maxima (PU11), and Pathfinder (D21), the VG30E w…
Production years 1984–1995 meet applicable emissions standards for their respective model years and markets (VCA UK Type Approval records for relevant chassis codes).
The Nissan VG30E is a 2,960 cc 60-degree V6 petrol engine engineered for mid-size sedans and sports coupes (1984-1995). It combines electronic multi-point fuel injection with a single overhead camshaft per bank to deliver smooth, linear power and reliable everyday performance. Designed to meet the emissions standards of its production era, it prioritizes durability and refinement over peak output.

The Nissan VG30E was used across Nissan's Z31/PU11/D21 platforms with longitudinal mounting. This engine received platform-specific adaptations-different intake manifolds for the 300ZX versus the Maxima-and from 1987 received minor ECU updates for emissions, creating minor interchange limits for electronic components. 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 VG30E's primary reliability risk is distributor shaft bearing wear, with elevated incidence in high-mileage or hot-climate vehicles. Nissan service bulletins document this as a common failure point, while owner reports frequently cite ignition-related drivability issues. Extended service intervals and heat soak make timely distributor replacement critical.
Analysis derived from Nissan technical bulletins (1985-1995) and aggregated owner-reported failure data (1990-2023). 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
Yes, the VG30E is renowned for its mechanical durability and longevity when properly maintained. Its cast iron block and simple SOHC design are very robust. The main long-term concern is the distributor, which should be monitored or replaced preventatively. With regular oil changes and cooling system care, these engines can easily exceed 300,000 km.
The most frequent issues are distributor bearing wear (causing misfires), coolant leaks from hoses or the water pump, noisy valve train due to lack of adjustment, and intake manifold gasket leaks. These are well-documented in Nissan service bulletins and are generally straightforward to repair.
The VG30E was used in the Nissan 300ZX (Z31, non-turbo models from 1984-1989), Maxima (PU11, 1985-1990), Pathfinder (D21, 1986-1995), and the D21 Pickup truck (1986-1995). It was the standard non-turbo V6 for these platforms during its production run.
Yes, but gains are modest. Basic bolt-ons like a performance air filter, free-flow exhaust, and ECU chip can yield 10-15 kW. More significant power requires internal modifications or forced induction, which is complex. Its strength is torque and reliability, not high-RPM power. Tuning is popular for off-road Pathfinders and Pickups.
Fuel economy is moderate for its era and size. Expect approximately 12-14 L/100km (17-20 mpg UK) in city driving and 9-11 L/100km (21-26 mpg UK) on the highway, depending on the vehicle (sedan vs. truck) and driving conditions. It prioritizes smooth power over efficiency.
No. The Nissan VG30E is a non-interference engine. This means if the timing chain were to fail or jump, the pistons will not contact the valves. While a broken chain will still stop the engine, it prevents catastrophic internal damage, making it more forgiving of timing component failure.
Nissan originally specified API SF or SG grade oil, typically in 10W-30 or 10W-40 viscosity. Modern high-quality conventional or synthetic oils meeting API SN (or higher) in the same viscosity grades are perfectly suitable and offer better protection. Change intervals should be every 5,000-10,000 km.
