Nissan VG is 2.0-3.3L V6 piston motor, employed for a number of vehicles from the brand’s range. The debut motor of the lineup appeared in 1983 and soon, VG turned into the first assembly line V6 motors in Japan. Keeping iron block plus aluminum heads, the primary motors of the range received a single overhead camshaft with two valves per cylinder.
Hereinafter, some updates were made, leading to the creation of motors with other blocks, plus a dual overhead camshaft with four valves per cylinder. Moreover, the brand applied its specific modification of variable valve timing to make idle smoother plus achieved more torque at low and medium rpm. Block contains a monoblock main bearing cap.
Engines with such updates were utilized for Nissan GTP ZX-Turbo plus NPT-90 racing automobiles, which managed to gain victories at the IMSA GT Championships for three consecutive years.
Since 1984, VG motors were utilized in a vast number of Nissan automobiles. In 2004, their manufacture ceased and led to the creation of the VQ lineup.
VG33E, a 3.3L V6 60° four-cycle naturally aspirated ICE with water cooling, was released between 1996 and 2004.
Keeping cast-iron block plus 2 aluminum heads with single overhead camshafts and two valves per cylinder, these motors feature a multiport fuel injection system and an electrical ignition system with mechanical timing and distributor.

VG33E employs 2 kinds of fuel injection timing:
- Sequential multiport fuel injection works contemporaneously with the motor. Fuel enters cylinders at every cycle pursuant to firing order.
- Simultaneous multiport fuel injection is launched after a motor’s start or during fail-safe system functioning. Fuel gets injected contemporaneously into all cylinders twice during a motorcycle.
ECU manages the ignition system, serving to preserve optimal air-fuel proportion for any type of engine operation. ECM stores ignition timing information, creating a map. ECM gathers data about injection pulse width plus camshaft disposition sensor signal. Calculating all data, ignition signals get forwarded to the power transistor. The compression index equals to 8.9.

Nissan 3.3 VG33E Engine Problems and Reliability
- Timing belt
- Water pump
- Fuel sending unit
- Oil leaks
Wear and tear components in all engines wear down faster than the engine internals. When it comes to gaskets and seals, age is just as damaging as mileage. The point is that the Nissan VG33E was a very dependable engine when it was a little newer. They may still be trustworthy, but older vehicles require more maintenance.
Nonetheless, keeping the VG33E 3.3 engine in good working order is critical. Look for a vehicle and engine that have been well cared for. Quality oils, timely fluid changes, and rapid problem repair are all beneficial. The Nissan VG33E engines have proven to last considerably longer than 200,000 miles without having many significant issues along the road.
Is the Nissan 3.3 V6 Engine an Interference Engine?
YES. However, despite this, many auto mechanics report that when the valve belt breaks, it does not always have the valve to piston problem. But the water pump and thermostat needed to be changed every time.
VG33E is an outstanding motor. Though it may seem to lack energy compared to modern models, it easily copes with various types of terrains. Plenum construction is rather complex, but still, every car enthusiast will cope with it.
Elements are for sale at pretty low prices. The motor may run for more than 300,000 miles with no faults if proper maintenance is provided.

I got Nissan Elgrand with 3.3 VG33E roaring 🙂
It’s 35k miles on the clock, car was made in 2000
Do I need to change timing belt?
Or is there anything else i need to change in this car? I live in UK, car is imported from Tokyo.
Much appreciate for any tips 🙂
Hi, Michal. My congratulations!:)
You cannot be sure that the previous owner changed everything on time, so my recommendation is to change engine oil (with filter) and check the timing belt with all other drive belts. This is a must.
Next parts should have been replaced earlier (you can inspect them and change if needed):
– Air cleaner filter (every 30k miles)
– Fuel lines (check every 30k miles)
– Cabin air filter (replace every 15k miles)
– Automatic transmission fluid (check every 15k miles)
Timing belt (check every 30k miles and replace at 105k miles)
Spark plugs – replace every 105k miles.
Inspect belt for cracks, fraying, wear and oil. If necessary, replace (when engine is cold).
Inspect drive belt deflection or tension at a point on the belt midway between pulleys
