If you look at the specs for the new Dodge Caliber, going with the R/T trim model nets you a 2.4L DOHC I4 with VVT pushing 173HP and 164Lb/ft. From what I have been able to find, the engine is an upgraded 4G69 and was co-developed by Mitsu, Dodge, and Hyundai. The engine apparently will end up replacing the current 4G69 in the next Lancer Ralliart and Outlander.

This kind of scares me. Considering the engine is now based in an aluminum block and uses a resin intake and exaust manifold, it should be considerably lighter then our iron block/aluminum head setup, AND it generates more power. I'd hate to see our engine go obsolete after just four or five years, just as companies are starting to lean more aftermarket support towards the ralliart.

 

wow, i didn't know that, maybe those parts are transferable to our engine and we can net those gains!

 

nooooooooooooooo - not another design to catch up with. Jeez, I am still trying to get the product range finished for the Lancer series. Now they add another variation. That only makes 5 new model car / engine packages we are workingon at this moment. Now you tell me theres a 6th?.....

on the positive side, there is again a high probability of compatability of parts, and in all honesty, when making the first round of foundation parts, its not that hard its whenyou start getting into the heavy internals that it starts getting demanding.

Alloy block, resin manifolds they are all easy things. The DOHC is really where the hp gains are coming from in the majority and evne thats not going to be a large issue. More than likley they are using hybrid 4G69 bottem end with probably the EVO IX cylidner head technology converted to N/A setup.

Sounds hard but after working on Mitsubishi for so long, you get used to reading between the lines and seeing where the components come from and how they mix and swap from teh parts bin. Why make something new when you can combine something already in existance.

 

Speaking of that didn't anyway happen to catch the autoweek article on the new SRT-4 Caliber I believe it's the same engine above or possibly close to the EVO X engine ya never know but here are the apparent specs for the 2007 Dodge SRT-4
(copied from Autoweek article)

Caliber SRT4, which replaces the Neon-based SRT4 sold from 2003 to 2005, launches the company’s performance small-car formula to a new high. Under the hood (and functional hood scoop to direct cooling air into the engine bay), SRT4 features the first application of a turbocharged version of Chrysler’s global 2.4-liter four-cylinder engine, producing 300 hp and 260 lb-ft of torque. It makes 70 more ponies than the 2005 SRT4 (and 85 more than the first 2003 model). Power runs to the 19-inch front wheels via a standard six-speed manual transaxle.

Brakes are borrowed from Chrysler’s big cars like the 300C, with 13.3-inch vented front discs with dual-piston calipers and 11.8-inch single-piston rears. Suspension is lowered about one-half inch compared to a stock Caliber.

SRT folks say all the extra bits translate into these numbers: 0 to 60 mph in 5.9 seconds, sub-14-second quarter-mile times and 60 mph to 0 in 115 feet. All this, while still delivering an estimated 28 mpg on the highway.

“With 300 horsepower under the hood, the Dodge Caliber SRT4 will dominate the sport-compact market,” says George Murphy, Chrysler senior vice president of global marketing.

Caliber SRT4 goes on sale in spring 2007.

 

This could be interesting a DOHC Mivec... it could be a simple head transplant for existing SOHC which could be a basic mod upgrade to be done....

 

that would be great if we could do some kinda head swap.

 

head swap head swap la la la la la. (i love frankenstines!)

 

Too bad Chrystler sold all it's stock and what not of Mitsu, so I don't think they're working together anymore

 

This will be good for you guys that get the new cars... Engine swap. Probobly going to need custom IC piping for the differences in the sheet metal but probobly possible, it is after all the same archecture.

 

This sounds like the "world engine" which has been talked about for awhile. The idea is for many cars, across numerous manufacturers, to have the same engine for the sake of driving down costs, and hopefully increasing reliability.

 

I did a head swap on another car before....but it wasn't SOHC to DOHC....it was DOHC to DOHC. It was not easy (took 2 people about 8-10 hours), and I am guessing that actually trying to swap a SOHC to a DOHC would be more difficult.

 

Guys I really think this is the dodge neon SRT-4 engine. The one that holds 1000 hp on the stock block. Which is good and bad. Good for them and bad for us! Seriously I don't think they're going to phase out our motor too soon, they put it in the Eclipse and probably won't want to retool again for awhile so we're safe for now. Would have been nice though!

 

As long as is not like that 2.0 dohc that Mitsu and chrysler shared(Neon, Eclipse),and then sold the blueprints to Hyundai and they came up with their own version of it. Anyways that engine sucked badly. As long as it ends up a good engine, sounds nice.

Ill just wait till someone crashes and yank that engine out. Then I could put it in my car....heres hoping

 

wait a minute , i thought our iron block was superiour to the majourity of aluminum bocks out ther, and why would we be concerned if this block is indeed a 4g69 knock off? i say good let them keep making parts for our engines no-matter what car they put it in cause eventually ,its only going to benefit us in the long run.

i wouldent worry about it, thier not trying to phase out our engine, they just know the potential of it and want to squeeze as much juice out of it as they can.

 

What is it even possible to swap form a sohc to a dohc, and if so imagine what that kind of work would cost. Fellow ralliart warriors fear not, do not overlook the big picture. The new eclipse is powered buy a six and a four banger. The four banger probably being the more common engine ( the same as ours) which means soon in good time all the aftermarket companies will make parts for the eclipse that can just as easily roll onto lancies. Oh ya i call our lancers lancies because i likes candies and the two words rhyme.
