Toyota MZ Engine - 3MZ-FE

The 3MZ-FE is a 3.3 L (3310 cc) version. Bore is 92 mm and stroke is 83 mm. Output is 225 hp (168 kW) with 240 lb·ft (325 N·m) of torque in the Camry and 215 hp (160 kW) with 222 lb·ft (301 N·m) of torque in the Sienna and Highlander. It also features VVT-i, ETCS-i (Electronic Throttle Control System — intelligent/DBW), ABS plastic intake, and increased throttle body diameter over the 1MZ. The 3MZ uses a new flat-type knock sensor, which is a departure from the typical resonator type knock sensor used on the previous MZs. Those MZs had poor knock control, or perhaps oversensitivity when detecting knock, and power loss up to 20 hp (15 kW) may be realized due to erratic ignition timing when using an octane lower than 91. The new flat-type knock sensor is a completely different design and detects more frequencies than the traditional resonator type, and thus, provides the ECU with more accurate data. A bolt goes through the center of the knock sensor, which then mates the sensor to the block on each bank.
