Basically so far the pro's of the vvti are that it makes more torque at half the rpm compared to the non vvti, it's a newer engine so less wear and already comes single turbo.
Are Toyota VVT-i engines good?
VVT-i advantages include increased torque and output, better fuel economy, and reduction of nitrogen oxide (NOx) and hydrocarbon emissions. The simple structure of the VVT-i makes it extremely reliable and easy to adapt for existing engine designs. Wide applications of the new technology are expected in the future.
What's the difference between VVT-i and VVTL-i?
VVTL-i is a system whose principle of functionality has been derived from VVT-i but it is different in a way that it alters the valve timing as well as the valve lift(duration). Dual VVT-i as the name suggests would carry out the same function but on two valves at the same time .
Does 2JZ have VVT-i?
2JZ. The 2,997 cc (3.0 L; 182.9 cu in) 2JZ has been produced since 1991 (first released in the 1991 Toyota Aristo). Cylinder bore and stroke is 86 mm × 86 mm (3.39 in × 3.39 in). VVT-i variable valve timing was added later in 1997 for the 1998 model year.
What is meant by VVT-i engine?
VVT-i stands for Variable Valve Timing-Intelligence, which is Toyota's name for the variable valve technology it uses in most of its vehicles.
45 related questions foundAt what RPM does VVT-i kick in?
When the engine is operating above 6000 rpm, the ECU activates an oil pressure switch which pushes a sliding pin under the slipper follower on each rocker arm.
What does d4d mean in Toyota?
D-4D actually stands for Direct Injection 4 Cylinder Common Rail Diesel Engine. Common rail diesels injects a fine mist of fuel into the engine at very high pressure. The result is the same power and refinement as a petrol engine, but with better fuel efficiency and lower emissions.
What's better 1JZ or 2JZ?
In reality, the stock bottom end of the 1JZ can take around 650-700 horsepower reliably, while the 2JZ can take 800. If we turn this into simple math, we can see that the 1JZ's bottom end is good for roughly 260 horsepower per liter, while the 2JZ's bottom end is good for around 266 horsepower per liter.
What 2JZ is the best?
The 2JZ-GTE is the winner! Both engines are absolutely fantastic, both engines are very similar in factory performance and in tuning potential, while the 2JZ-GTE has some advantages due to it's displacement so the 1JZ-GTE has advantages due to it's slightly cheaper cost.
Is a 300 a 2JZ?
Does The 2003 Lexus Is 300 Have A 2Jz? The '03 Lexus IS 300 comes equipped with A single turbo charge of the Toyota Supra 2JZ-GTE, and it drives off a single exhaust pipe. The Lexus brand does not allow any tuning of cars. This should not be a surprise.
What engines have VVTL-i?
Dual VVT-i
It was first introduced in 1998 on the RS200 Altezza's 3S-GE engine. Dual VVT-i is also found in Toyota's new generation V6 engine, the 3.5-litre 2GR-FE first appearing on the 2005 Avalon. This engine can now be found on numerous Toyota and Lexus models.
How does a VVT system work?
Basically, it varies the valve timing by shifting the phase angle of camshafts. For example, at high speed, the inlet camshaft will be rotated in advance by 30° so to enable earlier intake. This movement is controlled by engine management system according to need, and actuated by hydraulic valve gears.
How long does Toyota VVT engine last?
The Dual VVT-i 4.0 V6 engine found in the 09+ models is smooth, quiet, and reliable with engine longevity easily reaching over 200,000 miles (320,000 km). It's no secret that regular maintenance and using high-grade oils and lubricants is the key to reliability on almost any engine.
Is VVT reliable?

How does Toyota VVT-i engine work?
Toyota's VVT is a cam phasing system, which is one of the most common in use. It uses a variator, which is hydraulically-controlled, to change the size of the inlet and exhaust valve openings, which also affects the duration of those openings as well.
What does JZ mean in 2JZ?
2JZ-GTE does not have its own engine code. Instead, “JZ” refers solely to engines, “G” refers to dual overhead cam setup, and “T” translates to turbocharged engines and “E” to electronically powered vehicles.
Will there be a 3JZ?

What is the point of a 1.5 JZ?
1.5JZ Benefits
The main (confirmed) benefit of the 1.5JZ upgrade is to achieve the additional displacement while keeping the 1JZ wiring and electronics, creating the perfect solution for those already looking to replace or refresh their 1JZ.
What is better 2JZ or RB26?
Both are large, inline six cylinders with similar dimensions and weight. The increased displacement of the 2JZ-GTE yields the same output but it achieves it's peak power at 1,200 rpm lower then the RB26. The 2JZ also nets 31 lb ft torque more at 400 rpm lower then the RB. This hands the advantage to the 2JZ.
Is a 1JZ reliable?
The most durable and reliable 1JZ is a simple non-VVT-i 1JZ-GE engine. The longevity is well over 200,000 miles (320,000 km), but they are old now and find one of these engines in a good shape is not an easy task.
