FJ80 Cummins

Does anyone know if there is a kit to adapt a Cummins 6cyl Turbo deisel to the 80 trans along with motor mounts?

I have a motor availible to me for $1500 including the computer, harness and motor.

Would this be a worthy swap?

I have done engine swaps in my Suzuki's and kits make them a very easy swap.

Thanks in advanced and yes I did search and found a Cummins in a 55, not an 80.

I think you're on to something here...be sure to keep us posted if you go through w/ it. Don't know what kinds of kits are out there - but here's who I'd get in touch with.

No adapter to that tranny. The engine is reguarded as too heavy for that front axle. It would need a custom set of springs for sure. Also, because of the height you would need a pretty decent sized body lift. Also length with the radiator and intercooler is going to be an issue. It would be cool. Personally, I think that motor puts out too much torque for the 80 drivetrain. I think it would be easier to take a whole donor Dodge and slap an 80 body on it.

IIRC there is ( was) a girl doing a Cummins 4BT in a 80 series. Anyone recall?

I think the Isuzu 4BD1t would be the hot ticket in a 80. Lesss vibration in a NPR motor is reported.

link to a smaller 2.8 in a cherokee. Interesting conversion though.

It would be way easier (altough costly) to put in a Toyota 1HZ or 1HD-T in it. At least those engines came in that rig to begin with. Bolt right up to that A440 auto tranny too.

That Cummins is to big and heavy for that front end.

Here are engine suppliers.

P.S., I would sell that Cummins for as much as you can get and buy a Toyota 1HZ from G&S like I did. Just a thought.

The front end needs some work right now. I just bought it and it has 195k miles on it. Just put an Aussie locker in it. I would rather go with a 3B than an Isuzu motor as they are easier to acsess up here, even the 6cyl deisel from an 86,87 non turbo. The turbo deisels (1HZ 1HD-T) have some bottom end problems from the factory if you dont let them cool.

Still undecided

Thanks for all the replies.

Ill keep in touch HJ60guy.

I have done a bit or research on this topic. As far a cummins from a dodge it is a 6BT and a big heavy monster. I was/am considering putting a diesel in a 55.

The 55 that has the Cummins (was Royal Rose's) has a 6AT, a diffrent motor than what is in the big dodges. There is a 60 with a 6Bt from what I have heard. Nothing is imposible but here are some things to consider:

The challenges with mounting a 6bt in a 80 would be:

1. Length
It is a LONG motor, I believe longer than the totota *Fs and if you want a radiator big enough to cool that beast and an intercooler then you are running out of lenght!

2. Depth
It is a DEEP motor, From what I have heard to make a 6Bt fit you will need to get an aditional 4in or so of clearance so the oil pan does not hit on the front axle.

3. Transmission
you would to fabricate your own adapter. Also if you try to use the stock tranny behind that torque moster your automatic transmission will boil its fluid FAST in some situations, to avoid this you need a transmission cooler BUT a trans cooler would go in the front with the intercooler and radiator- see challenge #1. I would recomend a dodge transmission that will bolt up easier and is designed to take the power.

4. Vibration/flex
Cummins diesels produce great amounts of vibration, this vibration will "work" at a frame and cause pretty serious metal fatigue and cracks on a frame not built to handle that kind of shaking(like bending a piece of wire back and forth until it breaks). Flex: the Toyota frame will most likey be flexed harder than it was designed for by the torque of a 6BT, this torque flexing will probably snap a frame at a weak spot created by the rattle/shake of the engine over time.

I will not say it is impossible because anything is possible but I will say that it is going to have several chalenges, if you decide to do it please PM me I would love to know how it works out.

For my 55 diesel dreams I have considered the Cummins 4bt and turboing a 3b. I am not sure if a Turbo 3b will have the torque I want for towing though. I would love to see some numbers on one. In theory a turbo 3B would be super sweet, especially with a h41 behind it!

You can tweak a 4BT but so far there are two options. About the power of a 2F (maybe with slight nuts) and good mileage and bombed and shitty mileage but tons of power. Maybe there is an inbetween but I haven't found it yet. I think a 6BT would be fine in a 80 if it was an early model or if it was a later or high output then definetely turned down, way down. There is another guy who's put two into 60s, early 90's model with the Bosch VE pump at 160 hp and 400 ft/lbs (which would haul ass and get good mileage) and he says they are easier to install than a V8 and he loves them. They are huge and heavy though. I thing I would go up to a Cruiser diff up front if possible or have 35s at the absolute max. I thought a lot about this, it is pretty easy to have a set of custom coil springs made. I would do OME J size but for the 1200-1300 lb load. But I honestly do think it would be fine, 400 ft/lbs is no larger than a tweaked V8 and the 80 design seems to handle to turbos and superchargers that are making similar power. Granted yes the torque isn't there. And I probably wouldn't even think of using the stock trans, I would definetely use a 4L80E or something like that to probably a split case. So that is my $.02. I thought long and hard about doing it with an 80 before I found the 55. I do think the 4BT would be a good bet though. You can open them up, I am super comforable I just need a little more juice at higher RPMs to get over the hills but on the flats it is beyond fine and will hit 85, even 90, easily enough with 35's and 4.11s.

Hey now Mr., 1994, 95, 96 1HDT's (only some) had lower end bearing problems. 1HZ's never did. I researched the crap out of these things before I bought my 1HZ. Even then I still replaced the lower end bearings along with timing belt and water pump. I think a four cylinder (3B/13BT) is to small for that big heavy rig. I'd still go with a 1HZ. I wouldnt even be affraid of getting a 1HDT if I could afford it.

The GScruiserparts.com guys think it is an Australia-only problem that is related to the quality of motor oil down there. It seems like none of the Jap-spec models had the problem apparently...

*****Sorry for the partial thread hijack******

When you say shitty milage what are we talking about? Shitty milage with a diesel can be a good milage for a v8.

Having a 4bt what would you say about towing power? I am looking to be able to tow a trailer with a rig on it.

Turned up you will be fine. They say max with this pump is about 160 hp and 400 ft/lbs which with injectors ($200), an intercooler, and a smaller turbo housing ($150) you will can easily get, you will just smoke. Shitty mileage was about 12. I have been cruising for about a week and a half with it set the way it is and haven't used a half-tank yet so I think about 20-25 mpg is good. I have touched about 25 mpg on a good day and this is not being "light" on pedal but not particularly hard either. I think you could probably tow a car in tow fine but it will be slightly slow going and/or you will need to turn it up a little bit. The torque is awesome, once I get some stiffer springs I don't think I'll have any fears about towing especially with the NV4500 and the low 1st gear (really what it's designed for).

So far no one has gotten back to me (GS & Luxury) in requards to a 1HZ or 1HDT or even a 12HT. Any ideas on where to find them in the US or Canada?

Thanks again

I just found out that the "G" in G&S is in the hospital for some reason. I hope he is alright, he is a fireman by day (or really by night) so I hope he is OK! I'll forward his info. It took him about 2 weeks to get back to me as well...

Sheldon was just getting over a nasty flue also.

I think the guys have two 1HD-Ts slated for the test bed very soon, I think one is five speed while the other is auto.

No need for the trans. Just need the motor and the harness and the puter if it needs it.

Thanks all
