1987 2.5 4 speed 4x4 MJ diesel conversion ?

[Dr mac]

here goes first post and cool site.

 

I have a 122 ci toyota diesel engine in good condition. Also have a rusted to heck 85 f250 4x4 diesel .

Do I put the toyota engine in the mj 4x4 . Or put the mj on the f250 chassis ?

Has anyone fitted a mj to a ford 4x4 chassis around here.

The 2.5 in the 1987 4 speed mj is worn out 256k on it and lots of low end rattle at 55 mph.

 

Reason I want to go diesel is cost of fuel . As I have over 3k gals.of clean WVO at this time.

MJ's are unibody from the cab forward, so cutting the cab off would make it extremely weak. Also, I think the ford chassis would be a whole lot bigger than the comanche. If you must do the diesel swap, I would use the yota motor

Depending which trans is on the Toy motor, you may be able to change the input shaft of the Jeep along with the bell, then only have to make motor mounts to fit it in (I've been looking into that)

diesel cost isn't that great, and the conversion costs enough that you won't really ever get your $$$ back out of it.

If you try to put the MJ body on the Ford frame you will end up having to build custom crossmembers because the ford rails will now be a nice set of rock sliders to the MJ body, Also as stated before the MJ cab is unibody and has no body mounts to attach to the donor Ford frame.

well found out toyota corolla diesel 1984 uses other tranny bolt pattern then toy pu so no easy swap . also was upin the barn and remembered I have a 188d from a case loader .

The 2.5 has really bad blow by and low end rattle at over 50 mph . so will have to go with something soon . Do have a 2.5 but was from a front wheel drive chevy . And do not know if it has same bolt pattern

As would prefer to go diesel due to free fuel . Just picked up another 20 gal of wvo today .
