I know that the diesel engine doesn't rev up very high. The have a lot of low end power. For that kind of money I would invest it into something else. Three thousand is a lot of money. You can easily buy a used LT1 engine (a motor is electric) for that, or even less than that. You will get more horsepower and similar torque.

Sorry. I needed that.

You can have all the HP in the world. Torque will let you climb up a wall.

There are alot of good options for a diesel swap. The Cummins 3.9 is a great engine but it is very tall and requires a 4" lift to clear the pan. A cummins 3.3 is a little shorter and can put out 110-120hp 350lb-ft of torque. You might look at the Mercedes diesel also. Look into Phoenix Castings in Nebraksa, they make adapters for the sae bell housings to ford, chevy, jeep and dodge trans.

It cracks me up all the assumtions that are still made about this swap.

It is all a matter of opinon and what you want your jeep to do and be capable of, therefore research is the most important thing, but I have done 3 V8 swap into YJs, and the 4BT is the the most fun to drive out of any of them, in my opinon.

Check out my build thread....

http://www.jeepforum.com/forum/f12/4...-pics-1275843/

The 4BT is about 700 lbs, and is capable of way more power and torque than the 4.0 could dream of. The 3.9 Cummins does not put of great power and torque numbers stock, but the great thing about them is the potential RELIABLE power they can make without too much modification.

X2 with the 4BT. I was just talking about this very swap on the way in this morning. Sweet build Yound Jeeper. How much total do you think it cost you to do the swap?

I THINK I am around the $6000 dollar range, including the jeep (not including the jeep body I set on fire )

I bought the Jeep without a powertrain for $1400 I think, so I think you should plan on spening at least $4000 on this swap, it all depends how you do it.....

I may be way off, but I prefer to no keep track of how much money I put into this thing haha.

I love that 6.2 YJ! I have been playing with the idea of a Duramax diesel in a Cherokee...

Same here, eats LT-1s and pulls a pair of jeeps without issue when asked to do so. Does it all at a nice low RPM. The turbo diesel and a good programmer are just good fun :-)

But as mentioned above, there are a bunch of good choices and it comes down to whats fun for you. Personally, I do not like a diesel on the trail, the vapor gases everyone out and is noisier than I would personally like. I go for peace and quiet as much as I do for fun. There is also the if you run out of fuel no ones going to have any diesel fuel thing to. But I love diesels.

I love my 01 24v cummins, and I dont even have a programmer yet.

One down side of diesel on the trails also is IF you do run out of fuel, its usually really bad on the injection pump, and you will be bleeding lines.... i guess the same situation is possible if you are low on fuel and on a steep incline......but just dont run of of fuel haha....

Ignorant statement is ignorant. I have a Golen 4.7 stroker and am over 300 tq.
Google more, post less.

I don't have a programmer for mine, it's a company truck but I get to use it as a tow rig. I love the torque, but I honestly think my '99 silverado 5.3 was quicker. (I am swapping that engine into my Jeep btw) What year is yours? mine is an '05

Sorry for the hijack OP!
