The new Cummins diesels are a 4.2L (256ci) V-6 and a 5.6L (342ci) V-8, both using a 90-degree V-block design with aluminum heads and an iron block. They use single overhead camshafts, a new EGR system, a single turbo, common rail fueling with piezo injectors, and a diesel particulate filter. The V-6 weighs in at 663 pounds, and the V-8tips the scales at 788 pounds, compared to the current 5.9L inline-six engines that weigh about 1,100 pounds.
The info is a little old, since the 5.9L is considered "current". Those are the basics though.

B:
Those sound like 2 pretty solid engines, and if they can find their way into the Wrangler engine bay, then GIDDYAP! The weight savings is definitely a positive as well. As long as the thing is durable and holds up, weight shouldn't be an issue.

Do you happen to know the weight of the 3.8L?

Yeah! I would like to know the weight of the 3.8L in the JK to see how much heavier the diesel would be. Your research would be helpful, I couldn't find anything!

I'm stumped!
Sorry player, but my search turned up a blank as well. I tried Mopar, Wikipedia, and a few other technical nooks and crannies on the web...to no avail. I could find bore and stroke (which I'm sure you already know), but no engine weight. The CLOSEST I found was this gentleman's website that listed a whole bunch of engine weights (the JK's wasn't listed).
http://www.bacomatic.org/~dw/library/txt/engfyi.htm
I don't know how accurate all of this is. The closest engine to the 3.8 on this website I could find was the old school AMC 6 199 (3.3L) produced from about 1965 to about 1970 that was found in the Rambler. This engine weighs in at an even 500 pounds (0.25 tons). Our current 3.8L is probably a shade under or over that, likely under with the advances in engine technology in the 30+ years since this engine was produced. Sorry I couldn't be more helpful, ace!

Thoughts on Jeep Diesels
I've been driving Cummins Ram's for a decade and loved them, so I got my wife a 2.8 Liberty Diesel in 2005. I was expecting a bullit proof drivetrain in the Liberty like I was used to in the Ram, but it just ain't there - especially in the tranny. Now I know the Liberty isn't a 3/4 ton or 1 ton truck, but still I expected better.
Don't get me wrong - the concept of a diesel Jeep is certainly good, but in the Liberty Chrylser cobbled together parts to make the vehicle and left the dealers with no training and even fewer parts. If they go with a diesel wrangler, I hope the execution is a lot better.
On the other hand, when its running right it runs good. Topped 30 MPG going across Wyoming last month on one stretch. Usually get 27-28 on the highway.
As to how the diesel GC's are selling, my local dealer has a bunch of 2007's left and they aren't moving, but in all fairness that is probably because diesel is higher then premium gas here and doesn't have anything to do with the quality of the product itself. If Chrysler had offered the lifetime warranty on the GC diesel, I would have probably traded the wife's Liberty on one of the 2007 left overs.
So anyway after all of this rambling would I buy a diesel wranger - probably, if it weren't more then $1500 or so over the base engine. The premium on the Liberty was right around there.
