5.7L Hemi?


Recommended Posts

It looks like about 32" from top of air cleaner to bottom of oil pan. What you got in mind? :brows:

 

What would it take to make one fit in a comanche?

 

I might be finding out in the next few months if I can get all the details worked out? :D

The motor is pretty compact. I have thoughts of doing the same thing. You know it has a electric throttle? I have a 2500 quad cab 4x4 and the motor pulls it around pretty good. It would be a beast in a mj. I've seen people put them in tjs so I would think with enough fabbing you could put 1 in a mj. You plan on getting a wrecked donor vehicle? Here is a pic of 1 going in a jk. http://nc4x4.com/forums/showthread.php?t=27677

I may be getting partial sponsorship from a local performance shop. All I have to do is run their name and logo on my tailgate or back window when the truck is done. :D

 

Will get all the details worked out in the next couple weeks. Need to make sure it will fit and if they can make all the electronics work.

*this* is a reeeeeeeeallly killer project. We're behind you all the way.

 

Going to do the updated dash and everything or stick with the classic Jeep stuff?

Be a perfect time for you to do the dash... :D Really complete the newer look inside and out.

One thing you need to consider is beffing the hell out of the frame rails especially in the engine compartment. You wouldnt want to put all that time and work into it and then rip your frame apart. Good luck and ill keep an eye out for you cause i want to see this done. OH and just a thought why not try a Cummins out of a ram??? That would be one mean beast and could you amagine romping down and pouring out black smoke form tires and exauhst man thats my dream I love a good cummins.

I've debated a diesel swap into my MJ project. I have an 86, so I'm still not sure if I'll be able to ditch the 2.5L and swap in a stroked out 4.0L as planned. I debated a small block Chevrolet, and even a Hemi. Here is what I can tell you about diesel swaps from my research:

 

You'd never fit a 5.9 or newer Cummins in an MJ. For multiple reasons of course. Mainly the height of the motor. The massive oil pan would reduce clearance severely and also reak havoc on your suspension setup. The second primary reason being weight. The 6BT or 5.9 CTD is over 1000LBS, and you'd be looking at some serious sagging issues even with taller springs for compensation.

 

There is however an MJ here in western PA, with a 4BT or 3.9 CTD in it. Around 200HP, 500ft/lb torque, and 30mpg. He's running that motor bolted up to an NV4500HD tranny, and around 6" of lift. Here's a picture:

 

 

 

And a link to the diesel swap page, which also includes a full list of specs for the entire Jeep: http://www.4btswaps.com/forum/showthread.php?t=585

Thats the exact swap i have dreamed of. You can find those motors in some bread truck or something and you can get them out of a motor home i believe and you can still get parts for them. I am going to be contacting him about this for all the info i can get and see how plausible it is. I knew that about the 6bt but one can dream. A 4BT with that torque would be awesome plus the gas milage it is perfect except it is still pretty heavy.

The motor is still used in many applications. They range from as you said, bread vans, to small heavy equipment such as skid steers, and wood chippers. I have a friend who works on Volvo equipment, and he comes across them somewhat commonly. I just got an Isuzu 6cyl. diesel from him for free, with only 150 hours on it. Unfortunately people are realizing what they are worth, and they usually go for top dollar. If you have a tough time finding one, let me know, I'm sure I can help you out.
