There is nothing wrong with pushrods. It's just a mechanism to make the valves go up and down, and they work fine for all but high revving engines.

Pushrods can be made high-revving, too. Look at the Corvette Z06. 7100 RPM redline out of a 7L pushrod V8. I know that's an extreme example, but it illustrates the point. Plus, pushrod motors have a lower center of gravity, which helps handling and stability, and have a much shorter chain driving the cam. You'll never see a pushrod motor with a timing belt, either.
 
From what I've seen the 3.8 is a whole lot better then the 3.0, but what's really special about it? I guess it's comparable to the older 3.1/3.4 GM motors, compact and good overall.

I'm afraid that in the Wrangler chassis ..beyond (perhaps) being a bit more free revving, it will offer nothing in terms of sensible power or economy. This chassis didn't need this evolution for itself. It needed it for economy of production. Most owners of the 2.4 that replaced the 2.5 only noted modest performance gains over the older 4 banger. No substantial change occured in fuel economy. It was still various shades of lousy.

That's decent for a car.

I was thinking in terms of motorcycles, say the 2006 Honda CBR1000RR, redlining at 12,200 rpm. >145 rear wheel HP. Drool.
 
As long as they retain the straight axles front and rear, I don't really care what the engine is. Like Gary said, a diesel would be really nice.

Did I say I wanted a diesel Wrangler. My wife is actually waiting on the 4-door version as a possible replacement for her Grand Cherokee. As a family, we have recently taken up the off-roading sport and she wheels her Grand Cherokee. She's taken a fancy to the Wrangler Unlimited, I showed her a picture of the 4-door(spy shots only) in an issue of Truck Trend and she loved it. She wants the 4-door, I want the diesel; anyone from DC listening?
 
Lets hope they don't even think about using the transmissions from the vans. They last to 60K-75K and boom. My mom has had a 1998, 2001, and 2003 all go to crap. The sad part is she only drives on the freeway.
 
The all new 2.4l is basically a Hyundai design

German-Owned Chrysler using Hyundai ideas(and engine design)

DaimlerChrysler Engine Venture Cuts Costs by $100 Mln (Update1)
Feb. 11 (Bloomberg) -- DaimlerChrysler AG's Chrysler, Mitsubishi Motors Corp. and Hyundai Motor Co. cut the cost for two joint-venture engine plants in Michigan by $100 million, or 14 percent, by streamlining the design, the venture's chief said.

The Global Engine Manufacturing Alliance now expects the factories in Dundee, Michigan, to cost about $600 million, President Bruce Coventry said in an interview today. The first plant will begin full production Oct. 1 and the second will start in September 2006, with a total workforce of 500 people, he said.

``Making small engines in the U.S. means it has to be absolutely world class or they won't be able to compete with engines from Brazil or Mexico where they have lower costs,'' said Michael Robinet, a Farmington Hills, Michigan-based forecaster for CSM Worldwide.

Chrysler, Mitsubishi and Hyundai are working together to trim the cost of building as many as 1.8 million four-cylinder engines annually, including 840,000 in Dundee. They plan to jointly make 1.8-liter to 2.4-liter engines for small and midsize cars in Michigan and in Japan and South Korea.

Chrysler, the third-largest U.S. automaker, and Tokyo-based Mitsubishi, Japan's fifth biggest, will share the Dundee engines.

Hyundai Model

The automakers cut costs in Dundee in part by studying a South Korean engine plant Hyundai, that nation's biggest automaker, opened in March 2004, Coventry said. Engineers from all three companies have collaborated to trim expenses, he said.

``This has to be the model for Chrysler at all of its plants if it wants to compete,'' he said. ``Any advantage an automaker gets only lasts 18 months before others catch up.''

The Dundee factories are expected to reduce by half the time Auburn Hills, Michigan-based Chrysler needs to make an engine, said Tom LaSorda, the unit's chief operating officer, last year.

The world's fastest engine plant is a Toyota Motor Corp. factory in West Virginia, which in 2003 needed about 1.94 hours to build an engine, Coventry said. The Dundee plants will be faster than that, he said, without giving a specific time.

Making engines at the Dundee plants also will reduce annual costs for parts and materials by about $100 million, or 23 percent, from what Chrysler spends on its current four-cylinder engines built in Mexico, which have less technology, Coventry said. With those savings and other changes, the new engines will be about 30 percent cheaper than those built in Mexico, he said.

The Dundee engines will be 5 percent more fuel-efficient and provide more horsepower than current Chrysler four-cylinder models, Eric Ridenour, the automaker's head of engineering, said Dec. 16. The new engines will be used in 12 Chrysler models and in 25 models for all three companies combined, Coventry said.

Seoul-based Hyundai hasn't yet agreed to use engines from the Michigan plants, Coventry said. The two factories can expand total capacity to at least 920,000 engines if they needed to supply Hyundai, he said.

The U.S. shares of Stuttgart, Germany-based DaimlerChrysler fell 21 cents to $45.89 at 4:15 p.m. in New York Stock Exchange composite trading and have dropped 4.3 percent in the past year.
 
Actually what that memo which is old doesnt say is that the Chrysler group actually led the design for their vesions to be used in CG applications, 1.8, 2.0 and 2.4 and 2.4 turbo. Many improvements over the ones Hyndai will use.


Mitsu essentially bailed on the project due to money constraints. they will make their own flavor for their own needs.
 
Aside from the 5% more fuel economy, I thought the memo pointed to engine manufacturing technique more then engine design.

You have to change the oil in them every 50K miles or so.. I have a 94 GC 3.3 with 201K+ miles on it, all original. The 95 GC parts donor has a good solid trans with 127K on it. My wife's 2000 GC has 80K on it now. Changed the oil for the first time at 73K. Will change it again at 100K or so. I can't believe that I'm the only one getting good service from them.
 
The 3.8L I guess is an ok candidate...much better than the heap known as the 3.7L Power Tech. Maybe they should scrap the 3.7L V6 and throw this sucker in the Grand Cherokee, Liberty and Commander... better yet, do the Hesco Inc offers and throw 4.7L V8 into the Wrangler..

DC should do this... bring back the 4.7L HO V8 with 265hp (but make it regular or mid grade friendly) and use the 242hp version of the 3.5L V6 from the 300. The 242hp version uses regular fuel and was used in the Intrepid R/T model. 210hp isn't enough power for the base Grand..
 
Here tranny fluid was always flushed at 30K. Reguardless, when I've seen Kia minivans go 150K with no tranny fluid replacement and no issues, it makes you wonder. It's a well known and undisputed fact that the Chrysler van trannies are crap.
 
A high-caliber Korean engine



New Dodge vehicle will use Hyundai's technology



January 14, 2006 ㅡ For the first time, a foreign-made vehicle with a domestically-developed engine will be imported. The crossover utility vehicle, which used an engine developed by Hyundai Motor Co., Korea's leading automobile manufacturer, will be introduced here in June, DaimlerChrysler Korea said yesterday.
The Dodge Caliber, which runs on the 2.4-liter "World Engine," made its first global appearance during the Detroit Motor Show 2006 earlier this week. The first sales of the Caliber in the U.S. market will be in April, two months ahead of its introduction to the Korean market.
The 2.4-liter engine installed on the crossover utility vehicle is said to have up to 170 horsepower and is 5 percent more energy efficient.
In July of 2002, DaimlerChrysler AG, Mitsubishi Motors Corp. and Hyundai Motor jointly established what is called the Global Engine Manufacturing Alliance (GEMA).
The alliance, with its headquarters in Dundee, Michigan, runs a "World Engine" program that has produced a family of world-class four-cylinder engines, including Hyundai Motor's 2.4-liter engine.
The engines have been in production since late last year, and are manufactured at two plants in Dundee, two in Korea and one in Japan.
In exchange for providing the four-cylinder engine, Hyundai Motor received 70 billion won ($72 million) in royalties from Chrysler.
DaimlerChrysler, which was focusing on the development of engines for large vehicles, decided in 2002 to purchase Hyundai Motor technology instead of independently developing engines smaller than 2.5 liters.
"Chrysler informed us last year that it would launch a vehicle that uses the Hyundai Motor engine," a Hyundai Motor employee said.

The Caliber is a four-door hatchback vehicle targeting customers in their 20s and 30s.
The vehicle, which combines the best points of sport utility vehicles and passenger vehicles, features a larger compartment space and more comfort when driving. It is considered to be the future design of leisure vehicles.
Kia Motors Corp., an affiliate of Hyundai Motor, plans to introduce a crossover sport utility vehicle in March.

The New 3.3 L and the 3.8L in Hyundai Cars right now have no relationship with Mitsubishi and Daimler Chrysler. They are totally Hyundai in-house design.
 
The 3.8L in the new JK (Just Kidding) isn't a Jeep engine. It makes peak torque at 4000rpm.
Useless. The JK is bigger and heavier than the TJ, they kept the tranny and axle gears the same, and they threw a mini-van engine in.
They use CV driveshafts too...haha what a joke. Lift it, and watch 'em explode. They also half-***'d the wheel pattern too. 5X5??? Either keep the 5x4.5 or go back to 5x5.5
Stability and traction control??? In a Jeep?

WAY TO GO SOCCER MOM'S!!!!
Congrats on your new Wrangler!
The off-road enthusiast is a dying breed.
RIP, my friends...

BTW, the only reason the JK has more ground clearance than a TJ, is because they went to a 32" tire vs the TJ 'Rubi's 31". That's it.

Not all of them are crap, as I can attest to. Having 3 trannys fail at about the same mileage from 3 different years, just doesn't compute. There must have been something else going on here. Since you reported a good maintenance schedule, I would question who did the maintenance.
