Cummins Anyone? (1 Viewer)

[nickw]

Yep! Great motor until you try to get parts for them. The 4BT is sort of cool because you can get parts almost anywhere for them in the US. Even uncivilized places like Wyoming. Try to find parts for a gasser Toyota in the middle of Toyota and it takes a few days. Get rid of your internet connection and try getting parts for a Toyota diesel in these uncivilized portions of the US, you'll be waiting. I couldn't even get parts for BJ60 locally in Idaho. How would I ever get them for a motor not imported for highway use in NA.

Jeremiah and his crew do great work. I think at times they get overbooked. But reasonable and clean installs would make me definitely consider them for a project. Just nice folks! For a small town Jeremiah is hooked up with sources for custom stuff to make things right.

That motor probably did come to the US.
They are also used in larger Toyota forklifts.
When my starter went (burnt) we cross referenced it to one for a Toyota forklift. Got a one taxed and shipped for $450 CND. Had it in 3 days.

In the US you could also get parts and the motor from spector.

In California, you'd have a really hard time smogging the rig after you installed the 1HD-T. That engine was never in a US production vehicle, so CARB has no emissions data for it, so it's disqualified and could never be street-legal.

The Cummins, OTOH, could go into a California Cruiser and still have a fighting chance at being legal for highway use.

Getting it legal for California emmission might be a problem.
Could not tell you there. Allthought I did see one on ebay the Spector installed and it was in California. So it might be possible.

Cheers,
Nick

Having had a dodge with a cummins in it for a couple of hundred thouand miles.... every freightliner dealer in the country stocks cummins parts all the way to long blocks, the wide spread use of the 4bt and that they are cheep( less than 4500 for a factory rebuilt longblock with injection and turbo) .. is the reason everyone is looking at it..

We all like the toyota motors but they are very expensive here if you can get the motor and trans here for less than 8k with shipping you are doing good. Where as we can all go down to the cummins or freightliner dealer or wrecking yard and get parts or a complete motor that is emissions rated and we can register......

Other than the vibration at idle the cummins motors are great. They last forever at the stock hp with very little matinence, and with the turn of a screw and a little adjustment will put out quite a bit more HP..

My 160hp 6bta is over 300hp with injectors and a turbo, the 4bta can just as easily be modified cummins even has 4bta versions rated up to 165hp and 400ft/lbs. The question then becomes the trainsmission and rearend....


Grease Cruiser

I still want to know what motor mounts you used and how bad does it vibrate at idle... and what did you do to the 700r4 to get it to survive....

Good and valid points.
You present a strong case.
Sounds like a good way to go.
Thanks for sharing.

Spector eh?

Hmmm...

 

[Grease Cruiser]

Grease- what stock accessories are retained in your conversion? Also, is it possible to retain the fulltime TC? How about retaining the stock A442F / A343F tranny? And where are you located?

We are located in Western Colorado near Delta. Yes you can retain the stock t-case although it is not a substantial savings. Unfortunately, at this time no adaptors are available for the later model Land Cruiser auto trannies.

As far as enigne accessories, everything is replaced except the stock AC system.

We use the stock liquid filled Cummins motor mounts and we turn up the idle to 900rpm to smooth it out. You can definitely feel a little vibration but it is not much.

I did get the impression that in California as far as smog is concerned you just can't put in an engine that's not original to the model.
But I don't know for sure.

 

[ed97fzj80]

My (admittedly limited) understanding is that you can do a transplant, but it has to be an engine that was used in a production vehicle that is/was for sale in the US, and the engine must be the same year or newer than the vehicle into which it is being placed.

A good example is the Cummins-powered 60 that was on Craigslist recently. That Cruiser isn't old enough to be smog-exempt, yet it's had a diesel dropped in it and it has a California title. Some things can be done.

 

[e9999]

I would be leery on basing a decision just on what you see around. It would not be the first time that the smog guys let something through and then get back at you later on. Or that they may catch one but not another. A job of this cost magnitude would deserve serious check with the ARB types beforehand.

 

[ed97fzj80]

Yes, I had a paragraph about that, then deleted it since I figured that spelling it out would be raising my regular pedantry to a whole new level. Anyone who would take on a project like this in California, without the prior written blessing of Those In Charge of These Things, would be asking for trouble.

Oil pan clearance?

Grease Cruiser,

Is there reason you did not use the factory air filter? (Centrifugal design removes dust and can use a snorkel with it)

Could the 4" lift be avoided if the oil pan was modified similar to this?

RAYJON:
project 80???..what did you use for a transfer case...(offset output 205?)... ???

I will be using an Atlas 4-speed mated to a 47re that will give me a 1:1, 2.7, 3.8, and a 10.5. that should take me where ever I want to go.

There is more about it here. https://forum.ih8mud.com/showthread.php?t=84611

 

[RAYJON]

Thanks...Project... I was wondering the only way I could see to do it with the dodge trans was to use the 205 like the early dodge diesels and convert it to an offset output..


Grease Cruiser thanks for the info... I know the liquid filled mounts help.. please keep us posted I really would like to see how this works out and what mileage you end up getting..

Another question----yes I am a pain...

I was wondering if a 4l80e will fit with an offset 205... that way the adapter off the bread van would bolt right up...and it would be a little stronger than the 700r4 and the split case..??

 

[OGBeno]

I don't want to be the bummer of the group and I really dig what I see here (and I know that Proffitt's makes incredible vehicles/modifcations etc.), but at this point, the vehicle ceases to be a Toyota in my mind.

Am I starting to sound like a purist? Maybe. I mean, we do get Toyota's for a reason (and it's not because it has an emblem that says Toyota).

Anyway, I would love a diesel too (bio would be better), but at what point do we sacrifice the original intent of buying LC's?

Just my very weak and newbie point of view.

Great pics....

[Project FJ80]

Well, I guess that all depends on what makes a Toyota, a Toyota. If we loose the f&r bumpers, side steps and oem wheels and tires and replace them with arb, slee, hanna and bfg, would that do it? Maybe an Axel swapp for an IFS to a solid axel setup. or completly cutting up whats left of our rig and making something new. Like the Landcruiser 80 SUT. looks kinda like the chevy avalanche, just better. or slees version of the shorty 80. or the all out tubed fj40 that we see on her. Some rigs look like they came from the factory, others look like... frankenstien. But underneath all that, is the knowledge that it is a Toyota, You cant pass it off as a Heep, or a chebby, ford or dodge. It will always be a toyota. Just cosmeticaly different. I think we are doing what the Factory wont. Adding more power, bigger tires, making it more capable, and making them look more like an off road vehicle ( for which they were ment to be) rather than a Scoccer Moms ride.
This is just the way I see it. I would love to have a factory installed turbo diesel from toyota.. but the price, and lack of avi of parts make it easyer for me to go with an older Cummins which uses no computers for no headachs.

To me, She will always be my Toyota,..

Hi grease, I am in the planning and purchasing stages of my fj80 4bt swap. Is there any way to retain comfort features such as factory cruise control with this swap? also I noticed that you ran the original brake booster and master cylinder on this swap, what did you do to make the vacuum for the booster?

Thanks.

 

[Tapage]

I like to be Toyoto as much as posible .. but for example, Toyota makes regular PS system .. whta to do .. ? swap it with other better ..

In other case I buy a new t-case gear set .. from marks .. non Toyota right . ? ut is made for cruisers .. valid . ?

 

[ChuckB]

There is much talk in the diesel section about CA smog laws. From everything that I have read I don't think it will be legal... but stranger things have happened.

Every once in a while I hate this state!

Good to see this thread still alive! The 80 that we did drove back to Seattle. It averaged in the low 20's for mileage. Not bad.

There are 3 different options that you have for needing a vaccum.
1) Convert to GM hydroboost like I did in my 60. Great braking power and no need for vaccum.
2) Install an electric vacuum pump. Kind of noisy when ignition is turned on but not noticeable when engine is running and does the job.
3) Run a powersteering pump and vacuum pump off of a 6BT. Best setup so far but spendy. A lot of 4BT's do not come with power steering so this may be the ideal choice for those motors.

The 80 did not have it's factory cruise control hooked up. But, after a lot of research, we may have found a way to do it. We did however, have the factory tach working!

Rayjon: The ring adaptor on the breadvan 4BT's come in either GM or Ford patterns. The GM pattern should work with a 4L60E. Problem is that you have to have some sort of computer for the shift points. An added cost. We have the 700R4's built with stronger gears and are plenty strong enough for a 105-125hp engine.

As far as keeping everything Toyota, I used to be a purist. I hated V8 swaps and such. My Cummins FJ60 conversion is the first Cruiser that I ever heavily modified. After driving it for over a year, this the only way to go. Sure, Toyota has factory diesels, I have had 3 of them. They are not the easist to find parts for when you have to have it on the road the next morning to go to work. With the Cummins, parts are readily available at any parts store across most of North America. I am not trying to sell the Cummins conversions. They are not for everybody. But, they are for me!
