The 4G63 is dead!... Long live the King!
The mighty 2,000cc 4-banger is coming to the end of its invincible reign.
So what's next? Rumours of a new four cylinder engine has been circulating for months.

Mitsubishi has joined forces with Chrysler US and Hyundai to manufacture multiple versions
of a new 4-cylinder design... The new "World engine"...
Here at last are some facts about Chrysler's version of what may be the new "King"...

* Benchmark performance at the best price

Chicago - Feb. 8, 2006: Chrysler Group's Street and Racing Technology (SRT) group will
take the SRT4 reputation to new heights with the introduction of the all-new, 300 HP
2007 Dodge Caliber SRT4.

"The all-new 2007 Dodge Caliber SRT4 delivers a strong dose of all- around performance
while delivering more than 28 miles per gallon on the highway.
Our new SRT pocket rocket is going to be a hoot to drive."

Street and Racing Technology
...The all-new 2007 Dodge Caliber SRT4's formula begins with powertrain, essentially explained
by four numbers: 85, 125, 300 and 260. The 85 is how much more horsepower than the
original Dodge SRT4 is available, which results in 125 horsepower per liter for a total of 300 HP.
The final number is 260, as in 260 lb.-ft. of tire-smoking, push-back-in-your-seat torque.

Standout Powertrain
... The all-new 2007 Dodge Caliber gets its motivation from an all-new "World Engine"
produced at the Global Engine Manufacturing Alliance (GEMA) facility in Dundee, Mich.
The World Engine is a family of small fuel- and emissions- efficient aluminum
four-cylinder gasoline engines co-developed by DaimlerChrysler's Chrysler Group,
Hyundai Motor Company and Mitsubishi Motors Corporation.

"The all-new 2.4-liter turbocharged World Engine delivers a level of power you'd expect from
a V-8," said Pete Gladysz, Senior Manager -- Powertrain, SRT. "With the engine in the
all-new 2007 Dodge Caliber SRT4, we were able to take advantage of tried-and-true
performance improvements, such as increased cylinder-head flow and higher
compression ratio, as well as newer technologies such as Variable Valve Timing (VVT)."

To achieve its high-performance Dodge Caliber SRT4 configuration, the aluminum 2.4-liter
World Engine block is specially machined for increased water and oil flow.
Unique cast pistons travel within iron cylinder liners, and are cooled by
oil squirters and affixed to forged connecting rods for high-revving reliability.

Tri-metal bearings are used for the connecting rods and crankshaft for high-performance durability.
A unique oil pump/balance shaft module keeps the reciprocating assembly well-lubricated
and running smoothly. An external cooler keeps oil temperatures within a safe range.

The aluminum cylinder heads are also a World Engine casting equipped with unique high-temperature
exhaust valves. VVT uses computer mapping to open and close intake and exhaust valves
at optimal points for efficient combustion and flow. The camshaft and micro-alloy steel crankshaft,
shared with the non-turbocharged 2.4-liter World Engine, are fully capable of high-horsepower loads.

Free-flow induction begins with an all-new air cleaner assembly that draws through an opening
in a front crossmember for proximity to cool air. The air is then compressed in a TD04 turbocharger
specially configured for the engine's inlet and outlet packaging requirements, and sent
through an intercooler to a 57mm throttle body.

Fuel is provided by a high-flow pump feeding injectors developed specifically
for the 2007 Dodge Caliber SRT4. An all-new engine management system designed by
Siemens -- the Global Powertrain Engine Controller -- keeps the powerplant
running at maximum efficiency and power.

On the exhaust side, spent gases exit through a free-flow system that features
two catalytic converters -- one immediately downstream from the turbo, and
another further along the 3-inch single-pipe exhaust system. Using two catalytic converters
in this way provides significantly better "light-off" for decreased emissions.
As with the previous-generation Dodge SRT4, the exhaust is tuned for maximum
performance while meeting federal noise regulations.

Power is transferred through a dual-mass flywheel to the six-speed manual transmission.
The dual-mass flywheel consists of two flywheels sandwiching internal springs that are
specially tuned to reduce noise and vibration. The GF DMT-6 six-speed transmission,
equipped with a limited-slip differential for uniform side-to-side power transfer,
is capable of handling up to 300 lb.-ft. of torque.

Torque is sent to the Dodge Caliber SRT4's wheels through equal-length halfshafts sourced
from Chrysler Group mid-size cars for their larger size and power-handling capability.

This new Caliber... packs a whole new drivetrain, including a new joint-effort engine lineup
titled the "World Engine", built by Global Engine Manufacturing Alliance, with the engine
plant being located in Dundee, Michigan.
This Alliance, or GEMA, is comprised of members of Mitsubishi Motor Company, Daimler
Chrysler Corporation, and Hyundai Motors, all of which will make use of this new engine series
in different forms and design schemes.

While the front wheel drive option will remain, the performance oriented Caliber RT and Caliber
SRT-4, will both come equipped with an electronically controlled All Wheel Drive system,
a first for Chrysler Corporation cars.

Engine Options
...The new Caliber will offer several engine choices from GEMA. The gasoline powered
engines all use the same block, with the variations in engine displacement coming from the
change of the engine stroke. This engine features beefy cylinder walls and enlarged water
jackets around the cylinders which will help in supporting forced induction applications.

The pistons used are short sleeved, and include graphite patches which help to reduce
engine friction, and when coupled with the combination balance shaft/oil pump system,
this increases the overall efficiency of this new engine.

The European offerings will include a 1.8 liter gasoline powered engine building 140
horsepower and 125 lb-ft of torque...
The American engine choices begin with a 2.0 liter, which like the prior Neon RT 2.0 liter,
produces 150 horsepower and 140 lb-ft of torque. The Caliber RT is expected to come
equipped with a naturally aspirated 2.4 liter building a 170 horsepower and 165 lb-ft of torque.

The SRT-4 model is expected to have somewhere between 235 and 260 horsepower, but
considering the desire to compete with the WRX and Evolution, the horsepower output of
that engine is merely speculation. What we do know, is that although this new car may not sport
the aerodynamic numbers that the Neon did, it will have ample power to make up for
whatever extra drag the new body makes...

The key during development of this new line of engines from GEMA was not only to develop
a new engine platform that produced the power needed to make this versatile sport-wagon
competitive with other cars in the same class, but at the same time, to bolster fuel efficiency,
which is as appealing as ever due to the steadily rising fuel costs worldwide.
Also, while the engine platform development was an effort by the GEMA group, the final production
of the Caliber engine likely may differ from the final design of the Hyundai and Mitsubishi engines.

The Chrysler engine utilizes ... variable valve timing, but Chrysler has put their own spin on it,
and added a new feature to further the efficiency and performance of this engine.
The variable valve timing system used on the new Chrysler engines is a dual variable valve
timing system, or DVVT. This system has variable timing on both the intake and exhaust
camshaft, unlike some others which only have variable timing on the intake side of the
combustion process. The camshaft timing allows for increased overlap at higher RPMs, and
the DVVT allows the intake camshaft to move through 40 degrees, with the exhaust valves
going through 35 degrees.

The 2.4 liter engine uses a composite plastic intake manifold which houses electronically
controlled valves. These valves are closed at idle through 3,200 rpm, blocking slightly
more than half of the intake port, thus reducing the level of fuel needed to reach the
optimum air to fuel ratio. But, once the engine reaches 3,200 rpm, the valves open,
allowing full air flow and full power. This system allows the GEMA 2.4 liter engine to make
roughly 20 more horsepower than the current 2.4 liter engine, found in the Dodge Stratus,
while allowing this engine to meet Ultra Low Emission Vehicle II (ULEVII) standards, and
increase average fuel mileage by about 5 percent.

As a sort of final touch, unique items such as specially an insolated oil pan and valve cover
were used to help remove as much engine noise as possible.

More to come...

since when a 4g63 is the world king of 2litres , obviously you are forgetting about
the ford bdg , sr20 de , det , ve , vtc and vvl , or the mighty aer 2.0 power plant
out fo the x power mg.

^ ^ ^ Just don't like to argue about things that I know very little about, my friend.
Seriously, no hard feelings from me wagon. Just trying to let gunner know that we
can disagree with each other here but we don't have to fight about it.
My job is only to collate your info and present it to everyone else... That's all.
I'm definately no expert. I'm hoping to "build project cars"...
not really trying to "build a reputation." Getting too old for that...
but thanks for the "heads-up" I'll edit my post. Laughing

I'm hoping that they'll bring in the Variable Turbine Geometry technology in the newer Evos.

^ ^ ^ It might make more sense to copy the 150GB "data" hard drive in my computer.
Less clutter... more car info... Especially since I plan to be around for a long time Laughing

Information further confirmed � just read about it in the June Issue of Road & Track.
Their "insiders" confirm the 4B11 engine with MIVEC, 4 valves per cylinder and a large turbo.
300hp@7000, 325lb-ft@3000!!! And, it's 50lb lighter than the old engine.

^ ^ ^ Yup. Pity they didn't stick with the new Evo 9 turbo for the 4B11T. A lot of potential there.

Haven't really paid much attention to the 4B11T yet but at a glance the thing that I'm sceptical
about is the "open" deck design. Perfect for competition use, or in a well maintained car but
I never really liked that idea for a high boost engine in a daily driver with just an average
maintenance schedule.
