Diesel Engine Swap?

So after drooling over the torque that these new diesels are pumping out, I'm really wishing that my TB was available with a diesel motor... Anybody do an engine swap on a Trailvoy? Feasability of following through with a swap of my 4.2 gas motor with a diesel couterpart?

There seem to be so many embedded computer interconnects between the engine and transmission and emissions controls, designed to be impossible to fiddle with for federal and state emissions reasons, that nobody's been seriously contemplating upgrading to a V8 from a I6. Once they see the hurdles they have to overcome.

I would like to get a pony for Christmas.

Both of us need to set realistic goals.

Diesels aren't good for racing, so what would the torque be good for? Rock crawling? We've been down that road. Fuel economy? My wife spends about $700 a YEAR on fuel for her ten-year-old Civic, and wants to upgrade to a Prius to get the fuel down to $400 a year. This makes as little sense as paying for a diesel TB upgrade justified by fuel savings.

Sorry to be the voice of the Grinch. Jeep Liberty is already available in a diesel.

In 2007 Jeep began offering the Grand Cherokee with the 3.0L Diesel found in many Mercedes, including the GL SUV. I hear they perform well and get good fuel economy, however, they have a 0-60 time of 10 seconds....no fun!

if you've got the time, funds and it's that important to you anything is possible. just putting some time and money in your 4.2 would gain you more for the money than switchin to the diesel though. i love the diesel's too but a full size truck is the only place i want one.

Just looked at the jeep site and their 3.0 puts out 215 HP and 376ft/lbs but only gets 17/22 mpg.

The price of diesel here is about 50 cents a gallon higher so saving on fuel money you might be barking up the wrong tree. Power wise the diesel has the torque but off the line you might be disappointed.

Do you tow much and you are interested in the torque?

It sounds like a fun undertaking at first glance, but as mentioned above....Diesel is almost 50 cents higher than gas. If you swap one in, you'll need an electrical engineer to make it work. But, then again, maybe you can find a wrecked 03 DuraMax and swap out everything, pcm, transmission, the whole thing....310 HP and 605 ft. lbs., hhhmm!......But I don't know what practical purpose it would serve.

Don't let these naysayer's discourage you from doing this! You can accomplish anything if you have enough money to throw at it

Wait until 09' when the 4.5L Duramax V8 arrives. It's about the same size and weight as a small block V8, but then you would have to buy a Tahoe.
