What is VVTL i engine?

What is VVTL i engine?

VVTL-i (Variable Valve Timing and Lift intelligent system) (also sometimes denoted as VVT-iL or Variable Valve Timing and Intelligence with Lift) is an enhanced version of VVT-i that can alter valve lift (and duration) as well as valve timing. The system was first used in 1999 Toyota Celica with 2ZZ-GE.

What cars did the 2ZZ engine come in?

All 2ZZ-GE heads from 03/03 onwards carry this modification even if the vehicle does not have the air injection system. Applications: Toyota Celica SS-II (Japan, 190 PS (140 kW; 187 hp)) Toyota Celica GT-S (USA, 180 hp (134 kW; 182 PS))

How much power can a 2ZZ hold?

Registered. The 250-275 “safe” range is wheel horse power. Something right around 300 is probably the “safe” max limit at the crank.

Which Celica has the 2ZZ?

In the U.S., that Celica model was called GT-S, a 180-hp (134-kW) thrill machine that could accelerate from 0 to 60 mph (96 kph) in 6.2 seconds. On the Old Continent, the performance model was called TS and produced 9 additional hp, while in Japan, the SS-II Celica’s 2ZZ-GE made 187 of them.

How does Toyota VVTL I work?

The VVT-i system uses engine speed, intake air volume, throttle position and water temperature to calculate optimal cam timing. The ECU can advance or retard the intake cam depending on light, medium or heavy load, optimizing output throughout the entire powerband.

Is 2zz GE reliable?

The biggest issue with 2zz engines were the early engines had a problem with their oil pumps so see if it has a new engine or a new pump. As far as reliability, make sure they have had regular oil changes because it has a timing chain and it’s really expensive to fix if it ran without regular oil changes.

How do I know if I have 1ZZ or 2zz?

2ZZ is aluminum, 1ZZ is plastic.

Is the 2zz engine reliable?

Can you turbo a 2zz?

The 2ZZ loves boost. Its high stock compression ratio limits us to 7-8psi but that is still enough to put 260-280hp to the wheels. Simply upgrade your pistons and you can push any of the three turbos to its limits which means you’re near 400whp on the bigger turbos.

What is the difference between 1ZZ and 2zz?

Different parts include crank, rods, pistons, valves, and more. The block has a larger bore (the 2ZZ has a larger bore than the 1ZZ, and a shorter stroke). The crank is different to reflect the shorter stroke. The rods and pistons are different to give the appropriate compression ratio and valve clearance.

How long does 2ZZ GE last?

If it is well maintained then you should easily be safe up to 120k. It is not uncommon for them to reach 200k.

What kind of engine does a Toyota 2ZZ-GE have?

The Toyota 2ZZ-GE is a 1.8 l (1795 cc, 109.5 cu·in) straight-four 4-stroke natural aspirated gasoline engine from Toyota ZZ-family. The 2ZZ-GE engine was manufacturerd on Shimoyama Plant from 1999 to 2011. The 2ZZ-GE engine features a die-cast aluminum engine block with cast-iron cylinder liners.

What kind of engine does a ZZ have?

The ZZ series uses a die-cast aluminium engine block with thin press-fit cast iron cylinder liners, and aluminium DOHC 4-valve cylinder heads. The camshafts are chain-driven. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke.

What is the engine redline of a lotus 2ZZ?

The “lift” engagement and the engine redline vary by application. Lotus 2ZZ-GEs are rev limited to 8,500 RPM, for example, whereas Celicas were rev limited to 7,900 to 8,200 RPM in North America, depending on the model year. The first Japanese versions were rev limited to 8,600 rpm with a peak of 190 hp (142 kW).

What is the difference between a 1ZZ and 2ZZ engine?

The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimised for economy, with torque emphasised in lower revolutions per minute operating range, while the latter is a “square” design optimised for high-RPM torque, yielding higher peak power.
