Performance modded 4G69 from Dodge!
This was from another forum ...this is the new Caliber SRT-4 engine that is being discussed...pretty cool.
Now... how do I get a DOHC setup....hmmm
That's right. Under the hood is a DOHC 2.4L engine aka the 4G69 MIVEC, pumping out 300hp and 260lbs of torque to the front wheels. Funny thing is, the new hyundai sonata (base) has the same engine and was the first USDM car to get the revised 4G69. All dodge and hyundai cars will be renamed, as only the mitsu will keep the "4G69" name mark. This is one tuff as nail engine, so long 4G63... the 4G69 is taking over!

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 head is 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 gas exits 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.

RE: Performance modded 4G69 from Dodge!
This is saying that Dodge has taken the Mitsu motor and done what Mitsu could not and/or would not do for us!! But, yes, the 4G69 will be in the Caliber SRT-4 which is supposed to be quite fast, so I'll be taking some pages from their playbook! I wonder how much the engine would cost...that would be a great swap...minus the electrical, etc that would need to be swapped also.
