if the 3b is beefed up a bit with a nice turbo, would it be powerful enough to move an 80 series? how difficult would the swap be? i don't remember this being covered before...
3B into an 80 series?

HaHa!!! Thanks for the laugh!! Apparently, you have never driven a truck with a 3B. The short answer is it would be a dog. A 12HT would be marginal, and that has more power than a 3b w/turbo or 13BT.
Considering the price of fuel, it's a legitimate consideration! Of course, the motor would have to be souped up considerably, especially the head. But I don't see why not, with a really big turbo, intercooler and upgraded oil pump.
So, possible, but not for the meek!

I wonder though if any fuel economy gains would go out the window with the beastly weight of the eighty. I bet the mileage would be pretty pathetic. Possibly even worse than the 3FE or 1FZFE already in it.
The new 4.5i Duramax would be a nice swap when they come out for the 2009 model year. They make 520 ft/lbs of torque and supposedly get 28-30mpg in a full size GM truck! I'm sure they will be pricey.

A 3b with a turbo in an 80 series would be no worse than a normally aspirated one in a 60 series. Some of us have put hundreds of thousands of miles on that combo. It would be almost, but not quite, as bad as a VW microbus. That being said, if you are going to the trouble of swapping a diesel in, why not choose a more suitable one?
Don't know what the standard HP output would be for a 3B, but HZJ80s had 130 hp under the hood IIRC. So if you're not a fastlane freak, go for it.
Good point...
3B = 90HP and 159ft/lbs
13BT (similar to a turbo charged 3B) = 120HP and 210ft/lbs
1HZ = 135HP and 187ft/lbs
Sorry to hijack, but I do find it impressive that toyota could pull just over 200hp out of a 6 cylinder engine 4.5L while GM could only pull 205hp out of my old 95 1/2 ton non-vortec 5.7L.
I don't know why toyota doesn't offer a diesel motor in the US market. It seems that if VW and diamler can find a market for diesel motors here, why can't toyota?

motors
we're looking at a bunch of different motors, i'm just looking for some 3b info for now.
we've considered the power thing, but it will be mostly for the trails, so with low range and the torque its got, we'll be fine.
what about tranny options??? motors mounts need to be fabbed up??? any axle/oil pan clearence issues you guys know of?
thanks again for all the info and suggestions!

Patience, grasshopper.
for a trail rig maybe a 13B-T would be a nice idea .. but for highway use or mountain pass .. never !
Not at least with stock gears .. and remember the 3B have a small power band compared to 1HZ engine that do it marginal well in a 80 series ..
If where me in USA .. I pic the 4/6BT route .. with a NV4500 and AA dapter to the stock t-case or swap a BF1A t-case from a 60 series ..

1HD-T uses the same block as the 1HZ, but has 165HP and 268 ft/lbs of torque in stock form. With an intercooler and tweaked fuel pump you can reach 210HP and over 400ft/lbs of torque.
Fuel economy in stock form drops about 10% from that of the 60 with the stock 3B, but substantially increases when you press that pedal hard
.
If you are going to all the trouble of converting to a toyota diesel, I would spend a little extra for an engine thats going to have parts available for a long time. Namely, the 1HZ. Its still in use in many cruisers around the world, and for those times that aren't "mostly for the trails," it will give you the power needed to go down the road easily. Especially compared to a 3B. But, if you do go the 3B route, make sure to document well. : ).
Holy hell....absolutely not. I just drove a friends 60 with a 3b again the other day.....they are sooo slow and quite underpowered. Granted the 3b is bulletproof, but the 80 is quite a bit a heavier and the 3b will not be able to pull it the way you want. I agree with the others that if you are gonna go through the effort, you should swap in an engine that can do it for real. MTC.
The 1HZ is definitely a good choice, it's indirect injection so a wee bit quieter, the BEBs are less prone to pitting as the 1HD-T and that was the engine of choice in the outback. But having a turbo... Hmmmm!!!! Sorry, I won't go back to normally aspirated, and like I said before, your fuel economy will be directly related to how disciplined you are with your right foot!!!
