The Toyota 2RZ-FE is a 2.4 L (2,438 cc, 148.8 cu·in) straight-four 4-stroke natural aspirated gasoline engine from Toyota RZ-family. The 2RZ-FE engine was manufactured from 1994 to 2004.
The 2RZ-FE engine features a cast-iron cylinder block and aluminum cylinder head with two overhead camshafts (DOHC) and four valves per cylinder (16 in total). The Toyota 2RZ-FE engine used Multipoint fuel injection system and Electronic Spark Advance (ESA) ignition system.
Compression ratio rating is 9:5:1. The cylinder bore is 95.0 mm (3.74 in) and the piston stroke is 86.0 mm (3.39 in). The 2RZ-FE engine produced 144 PS (106 kW; 142 HP) at 5,000 rpm of maximum horsepower and 217 N·m (22 kg·m, 159.9 ft·lb) at 4,000 rpm of maximum torque.
The breakdown of the engine code is as follows:
- 2 – 2-nd generation engine
- RZ – Engine family
- F – Economy narrow-angle DOHC
- E – Multi-Point Fuel Injection
