Toyota 2ZZ-GE engine was produced from 1999 to the 2006 year. The displacement of the cylinders is 1.8 liters (1796 cubic cm). The cylinder diameter is 82 mm, and the stroke of the piston is 85 mm. Equipped with the MFI fuel injection. The gas distribution system is designed as a DOHC with four valves per cylinder and an additional option VVTL-i. The compression ratio is 11.5:1, which increases the requirements for gasoline – it is recommended to use no lower than 95th gasoline.

Engine power is not constant, it depends on the engine settings for a particular car. For example, Celica GT-S, Corolla T-Sport, Lotus Elise and Lotus Exige car’s power is 189 hp (141 kW). For the US market in 2003, Corolla, Matrix, and Pontiac Vibe’s power capacity is 180 Hp, after 2003, 173 hp, and by 2006 164 hp. This is due to the change in standards (technology) of power measurement.

Toyota Corolla Compressor and Lotus Exige S were equipped with a chassis with internal cooling, resulting in a power output of 225 hp. (168 kW), and on the Exige 240R with an internal cooling charge, the power was 240 hp. (179 kW).

Toyota 2ZZ-GE Engine Problems And Reliability

After the implementation of the new engine generation, a question arose about new forced engines for FF models to replace 4A-GE and 3S-GE. It had to have the same dimensions as the 1ZZ-FE, unit output as “best world analogs” and minimal weight. Of course, not using the boost, and combining high power at high rpm with a sufficient torque at low rpm.

The First 2ZZ-GE, created with the traditional participation of Yamaha, was introduced overseas with the new Celica 230 in 1999.

ZZ features are described above. but the new motor had many radical differences…

The main pride – new aluminum linerless block on MMC base (this is not the “Mitsubishi Motors”, but “composite” material with alumino-silicate fibers and inclusions).

1ZZ-FE is a very long-stroke engine, so further forcing by rpm was impossible with the same bore/stroke ratio. As a result, the bore was maximally increased so the wall thickness between cylinders was reduced to 5.5 mm. Thinner is impossible because the gasket will not seal the head/block joint. Even if at this place could be inserted a liner, the bridge temperature would exceed all limits – so Toyota made a kind of “composite liner”.

The main problems are related to molding nuances and, in the absence of traditional cast iron liner, does not fix:

  • uniformity of solidification (causes hole forming);
  • porosity (the solidification process is slowed near the inclusions with lower thermal conductivity);
  • cracks (due to different solidification speeds near MMC inclusions and in the main aluminum volume, at the mold surface, and inside it);

With molding defects, Toyota fought by strong pre-heating of molding form, laminar filling it with liquid metal, vacuum-degassed forms etc.

MMC had low wear resistance – as known iron cast liner or block retains hone grid for a long time, but in the full-aluminum block, the grid even was not “cutted” but “collapsed” (the surface plastically deformed). This “feature” can not be eliminated, so Toyota achieved the maximum possible resistance by composition – and declared it as “sufficient”.

The piston for this engine was also manufactured by MMC technology, and the outside of the skirt was coated with phosphorus- and iron-containing applied coating compounds to increase the hardness.

Quite a long time was spent adjusting the so-called “liner”/piston rings pair to provide wear due to rings instead of a deliberately weak cylinder wall.

The second revolutionary innovation was the VVTL-i system (Variable Valve Timing and Lift).

The traditional VV”T” part is similar to 1ZZ-FE and responsible for improving low rpm torque, additional VV”L” improves maximum output at speed over 6000 rpm by increasing the valve lift from 7.6 mm to 10.0 / 11.2 mm.

VVTL mechanism is rather simple. For each pair of valves there are two cams with a different profile on the camshaft (“normal” and “aggressive”), and on a rocker – two different followers (respectively, roller and slider). In the normal mode, the rocker (and valve) is driven by a “normal” cam through a roller follower, and spring-loaded slider idling moves in the rocker. In the power mode, the locking pin is moved by oil pressure and backs the sliding follower rod rigidly connecting it with the rocker. When pressure is removed, the spring presses the pinout and the sliding follower is released again.

Different followers using because roller (with needle bearings) allows less friction loss, but at the same height of the cam profile provides less filling (mm*degrees), but at high speed, the friction losses are almost equalized, so to maximize the output the slider becomes more advantageous. The roller follower is made of hardened steel, and the slider is made of anti-snoring ferroalloy but requires to use special spraying system installed in the cylinder head.

The most unreliable part of VVTL was the locking pin. It can not move to operate position for one rotation of a cam, so inevitably occurs a partial overlap collision of rod and pin, causing progressive wear. Eventually, the worn pin will always be wrung out by rod in the initial position and not be able to fix it, so will always operate only the low-rpm cam. Toyota tried to solve the problem by thorough surface treatment, decreasing the weight of the pin, and increasing the oil pressure in the line, but without final success. In practice, failures of the rocker pins still occur.

The second common defect – rocker arm shaft mounting bolt break, causing shaft turns freely, so the oil supply to the rockers stops and VVTL does not work (also lubrication of the unit deteriorates).

The rest of the improvements can be considered less significant. Modified oil sump to avoid air capture by oil pump during acceleration. The intake manifold with a large resonator, the partition in the exhaust to reduce heat loss and faster catalyst warm-up.

The rubber spacers between the intake manifold and cylinder head to improve the noisiness Toyota made a new, high-tech, quite compact, lightweight,t and powerful engine. Moreover, unlike predecessors, it had a rather “flexible” character with normal torque at low rpm.

But, except for the other ZZ features:

  • increased compression ratio (11.5) requires high octane gasoline (RON 95).
  • “raw” and non-reliable design of VVTL rockers
  • “Disposable” as for all new engines, is compounded by high loads and use of specific materials – so it is the most delicate of Toyota’s engines. As experience shows, 2ZZ-GE and 4A-GE/3S-GE are worlds apart in terms of reliability.

    Good day. I am using a 2ZZ (1.8L) engine on a 2005 Runx. I will like to know the possible damage to the engine since it shut down while driving.
    Signs visible:
    Lost power while driving at 100km/h
    Showed engine light
    Temperature on dash looked normal
    Fuming radiator with no visible coolant.
    I really need to know so that i can see my options i.e. to repair or order another engine etc.
