The VG33E features a cast iron block and two aluminum cylinder heads with single overhead camshafts (SOHC) and two valves per cylinder. The Nissan VG33E engine is equipped with a multi-port fuel injection (MFI) system and a mechanically timed electric ignition system with a mechanical distributor.
Fuel system. Two types of fuel injection timing system are used.
- Multiport Sequential Fuel Injection It is used when the engine is running. Fuel is injected into each cylinder during each engine cycle according to firing order.
- Simultaneous multi-port fuel injection system It is used when starting the engine or if the security system is working. Fuel is injected simultaneously into all six cylinders twice in each engine cycle.
The ignition system is controlled by the ECU to maintain the best air-fuel ratio for each engine operating condition. The ignition timing data is stored in the ECM, this data forms the map that is displayed. The ECM receives information such as the width of the injection pulse and the signal from the camshaft position sensor. By calculating this information, the ignition signals are transmitted to the power transistor.
The compression ratio is 8.9: 1. The Nissan VG33E has a cylinder bore of 91.5 mm (3.6 inches) and a piston stroke of 83 mm (3.27 inches). Produces from 170 PS (125 kW; 168 HP) at 4,800 rpm to 182 PS (134 kW; 180 HP) at 4,800 rpm of horsepower and 266 Nm (27.1 kg · m; 196.3 ft · lb ) at 2,800 rpm or 274 Nm (27.9 kgm; 202.2 ftlb) at 2,800 rpm of torque.
