Will it fit? Has it been done? Can it be done? Seems to me that it would be the ultimate power plant for all around use.

The reason I ask is because I can get a wrecked 95 Ram 4x4 for $2000 with all the goodies included. Busted t-case and bent frame but the engine and tranny are all ok. The rig starts up and tries to move even with the busted case.

I don't think it would be much bigger than a 6.5l chev diesel - I got one of those in mine. that would be a definate tree stump puller.

That would be a cool one. If that truck is a three quatr. ton it has a d60 front axle. But It might have the axle coupler on the long side like a d30 yj.

Apparently there are adapters available to bolt the engine to a Land Cruiser tranny but the resulting combo may prove to be too long, too heavy, maybe too tall?

Here's a snip from Rob Mullen's FAQ:

PowerMark used to offer a conversion kit (p/n RK9525G) that was designed to
allow you to bolt in a B3.5/5.9 in place of a GM 292 I6 or 350 V8 in GMC cube
vans. In order to put this engine into a LC using the stock transmission, you
would simply need to get the motor mounts/bellhousing Advance Adapters sells for
putting a V8 in and use the Cummins engine instead, as well as possibly having
to modify the supplied intake system and radiator hoses. Unfortunately,
PowerMark has now gone out of business. Fleet Supply has bought up the
remainder of their stock and plans to continue production. They also plan to
introduce a kit for Chev/Ford pickups. The kits should be available from your
friendly neighbourhood Cummins dealer.

I think the Cummins B5.9, as used in Dodge Ram is definitely too heavy to put
into a 40 series, and is a little heavy for a 55/60/80 series. It is also a
little on the long side. The above mentioned kit would also work for a B5.9.

...

6BT5.9-160 DRY WT 880LBS LN 39.6" HT 36.8"

6BTA5.9 DRY WT 905LBS LN 40.7" HT 36.8"

END SNIP.

HTH.

I would not recommend a 5.9 Liter Cummins. The engine weighs over 1200 lbs and will produce too much torque for your frame. You will have to strengthen the frame and replace the drivelines because a Toyota tcase and axles will NOT handle the torque.

I think this is a case of too much weight and too much torque for a little vehicle.

Also, it is very long....

However, it works very well in my 2000 Cummins 4x4 truck with a NV5600. :)

the 6bt is a very heavy engine...it would require lots of frame enhancements...a 4bt would be a better choice and readily available (and cheaper). they were used in a lot of refer trailers.

the 6bt is much easier to find than the 4bt and the 4bt cost way more ..you can find dodge low mile engines for 2000-4000 dollars , a low milage 4bt runs 5000-6000 sure you can find 4bt's for cheaper but they have super high miles ... a new 4bt from cummins is going to cost around 12,000 dollars by the time you get everything you need ..
the 6bt is way to big for an fj40 ...
and the 4bt is very tall and wide you have to run a spring over to clear the oil pan , you will have to figure out your brake boster set up because there is no vacum . the fuel system is a pain ...
if it is for a street driven rig you will hate it .. it is not fast , it vibrates really bad and is super loud .. the list goes on . i personally dont think it's a good choice for an fj40 and that is coming from someone who has done it .. not someone who thnks they know how the swap would go .. so save yourself a huge headache and big expence and go with a small block chevy you will thank yourself in the long run ...
dont get me wrong i think the cummins are awesome engines just not in a street driven fj

Just got back from looking at it again. The engine only has 95,000 miles on it and uses no oil! The transmission looks like a nv4500? and the tcase which is cracked open is a HD-np241 and has passenger side output to the Dana 60 which is bent real bad. Unfortunately both axles are hashed from the tow truck driver winching the rig back up a 65' hill by the axles. I was(am)going to try to trade those in as cores to get new axles to put under the rig.
As far as the frame goes for the cruiser I'll start building a box frame from scratch because I don't think the cruiser frame will hold up to the torque. I'll also make it a bit longer in the front to adjust for length of the engine. Basically I'm going to make a custom cruiser built around this engine from the ground up.
I'm going to do it but it will take me a couple years at least.
