What is Needed for a 4cyl to inline 6

[littlezeeker]

what all is needed to put a 4.0L inline 6 into my 86' Jeep Comanche? As of now it has a 2.5L 4cyl in it it is 4x4 dana 44. Thanks :???:

a complete running 4.0 equipped XJ or MJ donor. just about everything has to go, from the wire harness, to the dash components, to the drivetrain. pretty much everything but the seats and axles.

Get over yourself. 4.0 MJs are not plentiful in most places. For most of us, we just can't "go get a 4.0 MJ".

I have too kind of agree with Darren,there are not enough benefits to the swap to justify it.

 

Only way I could justify the swap is if i planned to tow with the MJ. Performance gains are minor unless you do the HO swap,I have both a 2.5L and a 4.0L the 2.5l is my dd so I rarely drive the 4.0l truck but when I do its not like I'm blown away by the power difference.

 

And as far as offroad I don't see how having a 4.0l is gonna get you though anything a 4cyl won't.

 

If I was to do a swap from my 2.5l I think I would skip over the 4.0 and do something else.

it all depends on what kind of project you're looking for. did I have to swap in those ford axles? did I need the headaches of adapting the radius arm suspension? inventing my own parts? hell no. my truck is not significantly tougher than a stock MJ with a 44 rear and upgraded front U-joints. but I wanted a project (and lord knows I got it :D )

Well first off, I won't ever get over myself, I'm just too damn cool.

 

4.0 MJs are not hard to find. The only justifiable reason to swap a 4.0 into a four-banger or V6 is if you had done a ton of custom fab work to the truck, i.e. A cage or rocker replacements or unibody stiffeners. Something that can't be removed.

 

I'm right and can't be convinced otherwise.

in this neck of the woods, rust-free MJs for reasonable amounts of money are somewhat scarce. :(
