I think when he wrote gutless he meant the 3.8L v6 that comes with the jeep. Christ my toyota had way more sack then the jeep. I think the 4.7L would be enough to make the difference but there is nobody in New England that would even attempt to do an engine swap. I'm having a hard time to find someone who will do re-gearing never mind the engine swap.

 

I just had a 6.1 put in.... if you want an ultimate rig then do it and enjoy.

 

Would be nice to have a 6.1L in my JK....but The ULTIMATE RIG would have a 5.9 or 6.7L Cummins Turbo Diesel if you could squeeze one in and if the Frame can hold a 1100lb motor. The Cummin's would lay a beating on the 6.1L Hemi! Especially if you upgrade the turbo, add a stackable programer, larger exhaust...you could see a potential of +650HP and +900lb/ft of torque. If you want to get insane....add propane injection. Another advantage with the CTD would have the longer engine life and better fuel economy!

 

If I could have got my hands on one of the diesels they put in the grand cherokee .... i believe a 3.5..... I would have gone that route but way more expensive and difficult. the 6.1 has been an awesome option because the weight is only 40-50 lbs more than the stock mini-van motor and has uneffected the front suspension height. Overall all with all my other mods it's an ultimate rig for me.

 

I am panning your 6.1L SRT Hemi motor I would love to have one in my JK....they are no slouch on the road...and bullet proof. I still kick myself at times that I should have gotten the Magnum SRT8 over the my 5.7L Magnum R/T. However, at the time I thought 340HP was plenty for a family cruiser but I think now I would really like the extra 85HP at times!

I know my dream of a 5.9L CTD is almost unrealistic especially to squeeze into a JK as well the weight would kill the frame! Having upgraded my CTD on my RAM the power you can get out of them is just insane just by adding stackable performance chips or programmers, exhaust & bigger turbo, upgrading the torque converter.

 

Do you run auto or stick?

 

who did it for you and how much?

 

I have an auto which needs the added power more than anything. I am one that prefers an auto offroad. I have pics of my build that I will be compiling in the next few days.

 

Other than the cool exhaust note and speed, what was there that a stock JK would not have done? I missed it.

 

Screamin Lizard in Tx did mine and couldn't be any happier with the total job. They did an awesome job and were above and beyond in every area.......checked everyone out and I would highly recommend them.
