Cummins Anyone?

[e9999]

nice job!
and good to know!

this whole thing kinda rekindles my hopes for a long and happy relationship with my 80. I keep thinking what will happen in 10 years when gas is at $10 / gal.... Will I have to put it in a museum cuz I won't be able to afford to run it? But with a biodiesel, there is hope!

 

[dieselcruiserhead]

its 105hp and 250 ft/lbs 4BT
and 120hp 302 ft/lbs 4BTA.

You can make a 4BT a "4BTA" easiliy enough by turning up the fuel a hair..

 

[cary]

It makes a lot more sense when the engine is blown and you need to replace it. It also makes sense to me when you say the 4bt can be made to make 400ft/lbs torque without much trouble. I love diesels, but like them more when they have lots of power.

 

[Project FJ80]

True you can always crank up the engine 300-400hp, But what does that do to your fuel economy? you wont be getting 18mpg anymore,.. Also everything starts to wear faster, mainly everything behind the 4bt. at thoes power levels, things tend to break and twist apart much faster.
If you can do the install yourself, it will run you somewhere around $4-$8k running stock. My set up is running about $35K, but im using all custom and built parts, more bling then was needed.

Also, whats up with all the weight issues that everyone has with engine swapps and 200lbs over stock?? .. What about the steel bumpers, duel battieries, winches, lights, compressors, etc,... that there runs over 200lbs+ and with no ill effect to the vehicle.

squeezer; Your Idea about the 6bt was the same as mine... But the at545 transmission is not going to work. I also have one, and there is no place to direct connect a transfercase. Its also taller and wider, most of them have no Park Paw, and equire the Transmission disc brake to be used for park/parking. I went with the auto 47re, cause I did not want to have to shift all the time, nor did i want to make provisions to install the clutch setup. (which also adds extra weight to the front end.) Good luck with your project. Which ever way you choose, with enough fabercation and/or money, you can make anything work.

Grease Cruiser: You have an awsome setup going. a very nice, very clean install. I think the install price is fair. what hurts is when you buy the car with the install. $20K+... do you offer financing?

Heres my 80 with the I-6. just waiting for drive train parts and alignment to button her up . (should be done end of July)

Lots of interest in the Cummins.

Ok, first things first. About the cost of the swap. The $12K-14K includes the lift, the tires, and all the drivetrain parts, which most of which are rebuilt or new. Total labor bill, including the installation of the lift, is less than $4K. The rest is parts.

Not sure where someone got the idea that top speed is 65mph. The Cummins 80 will hold 85mph all day long and cruise mountain passes at 65+ mph.

Motivation behind this swap is not to gain power. If you want power, go with a Vortec. Nothing wrong with that. This particular customer wanted the ability to run sustainable fuels. Can't do that with a gasser. And......the COOL factor. Imangine all the jealousy of the soccer moms (btw, this conversion was done for a woman) when you pull up in a newer diesel Cruiser.


Rainy Day FZJ: You asked about a NV4500. No, it would not be cheaper. Actually about $600 more expensive. When you factor in the cost of the clutch components, $400 flywheel, and the fact that a rebuilt NV4500 is $1,500, the automatic is a cheaper choice.

gnx7: Yes, the Cummins are known to be loud and rattly. However, FJ62's and 80's had superior insulation to earlier models. We add a layer of insulation to reduce the noise even more. I would not say that you can't hear the engine running, but it is actually very quiet inside the cabin. You can easily carry on a conversation with all passengers.

Just so it's clear, we are not trying to pimp this conversion. We have 8 4BT conversions scheduled as of right now. I just wanted to post some pics as there was some interest in putting a 4BT into an 80. If you do want to talk about a conversion, feel free to call the shop at 1-877-PROFFITT or email us at info@proffittscruisers.com

I have received several PM's about the shifters so I decided to post a pic of them. We were able to use all the factory shifters in their stock locations. And, the overdrive button locks/unlocks the torque convertor so it feels like there is a 5th gear.

Also, I am not Jeremiah Proffitt. My name is John and I just work there. Jeremiah would love to participate more on the board, but he is just too busy.

 

[Grease Cruiser]

Sorry, my bad, the t-case shifter is not stock on the 80, it's actually from a 60 and controls 2WD, 4WD and Hi/Low.

 

[RAYJON]

having a cummins powered truck, how bad does it shake at idle?? Most of the 4bt's I have seen shake bad. and are rough little motors... but they do put out good reliable hp...


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

I know why you used a 700r4 to a split case... easy adaption and if you dont put injectors or a turbine housing on the 4bt the 700r4 should last...would like to see it in about 40k miles... just currious...


25 mpg from a 4bt is not hard to believe as I can get 20mpg from my 92 dodge 4x4 if I drive it nice...and parts are cheep for the motor..


as for the 85 mph comment the reason for that I think is the stock governer on the 105hp models will only take the motor about 2800 rpm.. with an overdrive and 31's it would be about 85mph.. now take the governer spring and change it and adjust the high idle and the motor will go 3500rpm no problem the newer dodge truck motors rev this high factory. You can do 100 without a problem with factory gearing.. as long as the transmission has an overdrive... and you run 33" tires..

That is actually quite reasonable - and I rarely say that about the cost of custom labor

And diesels do better at deep water crossings, no spark plugs to get wet. And I'd love to get 400 miles out of a tank rather than 200. Put a duramax or some other high power diesel in, and you loose that 400 mile range, cause you loose the mileage.

Thanks for sharing the pics! It's very cleanly done, and definately is getting the interest level up for several of us. Post back after a full tank has been run, and you have some actual mpg you can share.

Hey, Grease...what intercooler is that in the 80...out of the bread van, or NPR?

[dieselcruiserhead]

out of the bread van.. I can dig up the part number if you want. It is made by tippiecanoe company, there were recently a bunch on ebay if I recall. I plan on using teh same setup for my upcoming swap, this intercooler with a FJ40 radiator this time...

 

[nickw]

Very nice clean looking install.
But for the price, you might be better to try and install a 1HD-T toyota diesel.
They are a great motor. Stock they produce 170hp and 270 ft lb tourque.

Cheers,
Nick

 

[alaskacruiser]

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?

 

[chicago]

This is a GREAT thread. Ive been thinking about an engine to swap into my 62 wagon and this info has been very useful hearing the pros and cons to the diesels.
I have the I6, and though they last for ever...its really no fun driving when youre chugging up hill with a line of cars behind you with a top speed of 45-50 MPH!

and where would one (from the states) pick up one of those? Complete??

me likey diesels...

 

[Rainy Day FZJ]

Intercooler looks like it is from a volvo 7 series turbo or a 2 series. I like everyone else here is jonesin for one, bad!

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.

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.

 

[dieselcruiserhead]

Not that one. I am familiar with the Volvo intercoolers too, that is what I used on my last conversion. The one seen in the 80 in this thread came with the 4BTA breadvan...

You can get one from GS cruiser parts, or probably 4 wheel auto.
Wayne at luxuryimports.ca might also be able to get one.

Easist thing to do would be to import a half cut truck.
