to what bedrat said, a tj 4.0 isnt going to make that kind of torque unless has a form of forced induction(turbo charger/supercharger) or nitrous oxide. A stroker kit with an aluminum head would probably not even make 325 ft.lbs. a stock 4.0 makes 235 ft.lbs.  

yeah..I'm pretty sure he meant 225 there as all the others are on track...  

Looks like I am being forced to make my Jeep a weekend warrior, gas just hit $4 dollars out here OUCH!(Hawaii) I hate having to do that because I do enjoy driving my Jeep.  The diesel would be nice to have because of the better mpgs it gets.  

Gas prices are way out of line over here in cali too.  

I noticed that someone mentioned that the future diesel for the wrangler will be a Cummings.  I've been happy with my Cummings (Dodge Ram 03)- 18 city, 20 combined, 24 hwy.  Note, however, it has a stick.  My 95, with an auto, got 12, 15, 18 respectively.  This is true of a friend's 2007 Ram - auto gets 15 avg.  (He said he can get 24 hwy - if it's downhill all the way.)  Mating an auto with a diesel supposedly reduces mileage by 20%, just like most automatics reduce mileage on a gas engine (but by less).  And CVT's (which usually get just as good as mileage as a stick) are not able to handle the stress of a diesel.  Also note: automatics require more maintainence, and except for ATS Diesel here in Denver, I had not found anyone else who would give a 60K warantee on a rebuilt tranny.  I'll stick with sticks until my knees give out.  I only do 30k mi a year, but at 3.79 (last fill-up)the extra 4-5 mpg saves big $.  

You can take this with a grain of salt, but I read that Jeeps is now offering a diesel installation "kit" for the JK.  I say JK because I can't remember if it bolts into earlier year Jeeps.  True it's not production, but it did make sound like it would be easier for folks to convert their gasoline engines to diesels if they were so inclined with factory parts.
