HISTORY OF CREATION
Toyota Mark 2 was born in 1968 as a modification of the popular model "crown". Until the fifth generation, it even had the
name Toyota Corona Mark 2. Over the years, everyone began to distinguish the "Mark 2" and the prefix "crown" is a thing of
the past. At first, the model was considered a medium-sized sedan, but then it became a business sedan. The main difference
between the "Mark 2" was the presence of rear or all-wheel drive.
In the engine range in the Mark 2 there were engines for every taste. There were low-volume power units with a capacity of
about 100 horsepower. However, the real motorists of the "mark" remembered first of all the 1JZ GTE engine with a volume of
2.5 liters and a capacity of 280 horsepower in the TOURER V modification. This engine was produced from 1990 to 2007. It could
function with both a 5-speed manual transmission and a 4-speed automatic

UPGRADE 96’
VVT-i is Toyota's proprietary gas distribution system. From the English Variable Valve
Timing with intelligence, which means intelligent change of valve timing phases. This is
the second generation of Toyota's valve timing system. It has been installed on cars
since 1996. Working principle: the main control device is the VVT-I coupling.

Updated 1JZ-GTE, 1996.
In 1996, the Japanese updated the engine, so the 1JZ-GTE vvti appeared. In addition to the fact that the
turbo engine received a system that changes the timing phases, the twin turbo is a thing of the past. The
Japanese, instead of two parallel turbines, began to install one, but a larger turbine — CT15B.

In addition to the changes affecting the boost system, the updated engine received a higher compression
ratio. If on engines with two turbines it was 8.5:1, then the single-turbine 1JZ-GTE has a compression
ratio increased to 9.0:1. The increased compression ratio allowed to increase the torque to 379 NM and
make the power plant 10% more economical. Quite high compression, as for a turbocharged engine,
places high demands on the quality of gasoline. The 1JZ-GTE engine is recommended to be powered
with gasoline with an octane rating of at least 95, and given the unsatisfactory quality of our fuel, to avoid
the risk of detonation, it is better to pour 98 gasoline.

Gearboxes and their capabilities
There are two boxes to choose from — a four-speed automatic or a five-speed manual. The
automatic transmission is very fast, sensitive, quickly switches to low gears. There are no
problems with it. And it can also withstand enormous loads, so rear-wheel drive Mark II with
automatic transmission are often used in drift competitions.
Toyota's manual transmission is expensive and rare, so the Mark II with such a transmission is
also a rare "beast"

In the early 1980s, Toyota already had a successful experience in engine
development, including popular engine series such as the 3S and 4A. In an effort to
create a powerful and economical engine, Toyota set itself the task of developing a
new series of engines, which became the collection as "JZ".
The development of the 1JZ-GTE engine began in 1984. The main goal was to
creating a turbocharged engine that would be increased, but at the same time efficient
in fuel consumption. Toyota engineers sought to achieve maximum power while
maintaining reliability and vulnerability.
One of the features of the 1JZ-GTE engine is its design with a six-cylinder V-shaped
arrangement. The engine capacity is 2.5 liters. Engineers used aluminum blocks and
cylinder heads to reduce weight and improve heat dissipation.
However, the greatest altitude characteristic of the 1JZ-GTE engine is its
turbocharging. It uses enhanced power and torque. Construction with two t
