Nissan VG is 2.0-3.3L V6 piston motors, employed for a number of vehicles from the brand’s range. The debut motor of lineup appeared in 1983 and soon, VG turned into the first assembly line V6 motors in Japan. Keeping iron block plus aluminium heads, 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 block plus 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 was ceased and led to the creation of 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 aluminium heads with single overhead camshafts and two valves per cylinder, these motors feature multiport fuel injection system plus electrical ignition system having mechanical timing and distributor.

Fuel System
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 motorcycle.
Ignition System
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
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.

Question to master 🙂
Hi Dan,
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 🙂
Regards
Michal
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
