1. Year and model of the original truck.

1991

2. Brief details of the Drivetrain that was swapped in.

Cummins 2.8L crate engine package

3. What went really well with the swap?

Pretty much everything. We jus took our time, carefully designing the swap kit as we went along.

4. What was unexpectedly difficult with the swap?

Not finished yet, cruise control will be potentially difficult to get working since it's drive by wire, AC hasn't been attacked yet.

5. Mods...aside from drivetrain, if any?

Waaaaay too many to list here, check out this thread for details on build: Delta Vehicle Systems goes to Overland

6. Driving impressions after the swap...including drivability in daily driving (if applicable), highway travel, and, of course, off pavement.

Just took the rig on a "break-in" drive, the Cummins RePower Cruise. Boise>Idaho Falls>Missoula>Spokane>Boise. Total of 1,217 miles right off the bat. Mostly freeway driving, some dirt roads. Throttle response is a bit lacking, but we are working on a tune to address that.

Using the A440F seems to be the ticket. Doing this will keep the conversion cost way down, and it drives pretty darn nice.

7. Realistic fuel consumption after the swap...lol. :D

Seeing about 22mpg with 35x12.5x17 General X3's. Waaaaay better than the 3FE would be able to pull off!!

8. Five star rating for overall difficulty of the swap: *=relatively easy, *****=don't even attempt it unless you have some real good friends who are really handy.

Still working on that part. We intend to have a kit that makes it an almost completely "bolt-in" operation, minus welding in motor mounts.

Well, I guess I am comfortable to post mine now after semi-finishing the project.

1. Year and model of the original truck... 1993. Originally purchase 1998 as a family car. Was parked for 4 years - kids left the house. :(
2. Brief details of the Drivetrain that was swapped in.... 1HDFT/H151. Drivetrain work was done by Vally Hybrids in Stockton. Georg and Dom are my heroes!
3. What went really well with the swap?... Since it is an original engine for this vehicle, there were no complications. Blogs on this site helped a lot!
4. What was unexpectedly difficult with the swap?... Nothing specific.
5. Mods...aside from drivetrain, if any? Building a full camper, so the back will be a couch + fully functional kitchen. Hot water with circulating pump.
6. Driving impressions after the swap...including drivability in daily driving (if applicable), highway travel, and, of course, off pavement... Drove this weekend 2000 miles to Arizona and back including 4 wheeling. No issues at all.
7. Realistic fuel consumption after the swap...lol. :D... Got 23 mpg on this trip at 70 mph and also some 4 wheeling.
8. Five star rating for overall difficulty of the swap: *=relatively easy, *****=don't even attempt it unless you have some real good friends who are really handy... Probably ***. Blogs helped very much.

So I have been driving my 6BT swap for about 2 weeks, only issue I have is my alternator voltage regulator, is bad but I have another one, I believe my stand alone is about where I want it, I have full TC lock up at 35 and 45, I think the next thing is changing my gearing, to 3.54 . I have been getting 19-21.6 MPG ( I have a heavy foot ) and I am pretty happy with it, I get a lot of attention from the WTF looks and the OMFG I want one, I let my son drive it to school and his buddies are a little jelly :hillbilly: . I will do this again, maybe even buy one and flip it :steer:

Greetings Shocktower,
Good evening. It looks great! What gear ratio were you running to get the 19-21.6 mpg? Also, what was your tire size?
Thanks,
David

My foot must be a lot fatter foot than yours... 17 is the best before i got 3.55 gears and 19ish. Both situations with 35” tires.

You running a 4bt, do you burn diesel or bio-diesel 15-20 bio mix ??, what tune are you using do you have a fuel pin ?? what is your timing ??

Okay folks...I guess I'll start it off...

1. Year and model of the original truck.
Started out as an Oregon truck...1991 FJ80, 220+k miles.

2. Brief details of the Drivetrain that was swapped in.
Toyota 12H-T 4L direct injected turbo diesel, mated to the A440 automatic tranny and full time transfer case that was originally behind the 3FE.

3. What went really well with the swap?
I was really surprised at how easily and well the diesel slipped into the gasser tranny. Basically 12H-T ring gear, torque converter, bell housing...and then on to the gasser components from tranny onwards.

4. What was unexpectedly difficult with the swap?
It would have been a nightmare if I didn't have access to a bunch of misc. parts to figure out tranny cooling lines and stuff. Luckily, Sheldon and Greg of G&S are good friends and were instrumental in this project. Other than that...the exhaust system was a PITA and $$$ because the 12H-T dumps on the wrong side and there's a lot of bends before it ends.

5. Mods...aside from drivetrain, if any?
2-3" Procomp lift, 33" BFG AT KO, Airflow Snorkel, dual batteries with a Redarc Smart Start solenoid, ISSPRO pyro and boost gauges, manual boost controller (14 psi), etc. Oh yeah...it has a K&N filter...lol. :D

6. Driving impressions after the swap...including drivability in daily driving (if applicable), highway travel, and, of course, off pavement.
Awesome! The 3FE had more top speed on the freeway...but in every other application, felt like a slug compared to the 12H-T. It is noticably louder than the 3FE...sounds like an older Cummins...but I like that. :D

7. Realistic fuel consumption after the swap...lol.
With winter fuel, I was only getting 14.5 US MPG for city driving...but keep in mind that my work is only ten minutes away from my home...so the diesel doesn't really ever get to warm up. Seems like we've switched to summer fuel already...and I've seen an improvement already on the first tank. Right now I have 200 miles and there's still about a third of the tank left...with winter fuel I'd be down to less than a quarter already. I'll update what I'm getting in town with summer fuel after a couple of tanks.

8. Five star rating for overall difficulty of the swap: *=relatively easy, *****=don't even attempt it unless you have some real good friends who are really handy.
I'd say ****, simply because of all the custom work that needed to be done compared to if I had chosen to drop in a 1HD-T.

9. 2 to 3 pictures of your rig.




:D

It's on my sig line...but...
New project - 12H-T turbo diesel transplant into my 1991 FJ80.

:beer:
I love diesel, where I came from most of Toyota’s are diesel and I would love to make the conversion. I got a Fj80 that I want to make the swap, but I don’t know nobody that does.

I know of 2 businesses on Ih8Mud that do Toyota diesel swaps:

@orangefj45 - Valley Hybrids and Cruiser Brothers does swaps in Norcal, as noted above

@torfab - Torfab does swaps in Washington State.

I have worked with Valley Hybrids in Stockton. The guys there are amazing, and highly recommended. Georg and Dom have worked on my vehicles (3 diesel conversions over the last 10 years which I still own) and these are being driven daily on and off road. They can help you find a drivetrain too. All you need is patience, and they will do an awesome job. You will never sell the vehicle. :)
