Toyota 2NZ-FE 1.3L Engine Specs, Problems, Reliability. The 2NZ-FE is a 1.3-liter inline four-cylinder gasoline engine, the smallest version in the Toyota’s NZ household. This engine is utilized for subcompact automobiles offered by Toyota since 1999 (Toyota Yaris/Echo, Toyota Porte, and etc.). The 2NZ is closely related to the 1.5-liter version – 1NZ-FE. In 2000, the 2NZ-FE won the International Engine of the Year award in the 1.0-liter to 1.4-liter classification.
Like the 1NZ, the 1.3 L engine has an open-deck type aluminum cylinder block with spiny type, thin cast-iron liners. Decrease in displacement was accomplished by installing a new created steel crankshaft with 73.5 mm (2.89 in) stroke. In order to keep the compression ratio on the very same level, 1NZ engine block is lower than 2NZ block. In the rest, the bottom sides of the 1NZ-FE and 2NZ-FE are almost similar. There are a 12 mm crankshaft offset, created steel linking rods, and low-friction pistons (LFA). On top of the engine block, there is an aluminum 16-valve cylinder head with double overhead, chain-driven camshafts.

The consumption camshaft is geared up with variable valve timing (VVT-i). The valve diameter for intake valves is 30.5 mm, for exhaust – 25.5 mm. The valve stem size for both consumption and exhaust valves is 5.0 mm. the engine utilizes a sequential fuel injection with 12-hole injectors. The Toyota’s DIS (distributorless Direct Ignition System) has a modern coil-on-plug style and uses long-reach iridium-tipped spark plugs. The consumption manifold is made from composite material for lightness, and the exhaust is stainless-steel. Detailed details about these elements you can find on the 1NZ page.
In 2003, the 2NZ-FE was updated to fulfill European STEP IV emissions regulations. The revised variation has new-shaped pistons, brand-new exhaust manifold, an additional three-way catalytic converter, and a 32-bit engine control unit (ECU). Also, the engine received hydraulic lifters and an electronic throttle ETCS-i.
Toyota 2NZ-FE 1.3L Engine Problems and Reliability
Because the 1NZ and 2NZ engines are practically the same, their problems are comparable too. Typical problems consist of oil leakages, high oil consumption after 150,000 km, an unreliable timing chain, unsteady idling, and others. More information on these concerns can be found in the 1NZ-FE problems.
The 1NZ engine does not have power and especially torque. If you can still walk around on a subcompact hatchback geared up with 1.3 l 1NZ engine, then there is absolutely no dynamics at all on a little sedan like the Toyota Corolla. The 2NZ-FE engine life hardly ever exceeds 125,000 miles (200,000 km).
