Absolutely. Crawling is where diesels shine in fuel consumption.
The 23 mpg figure I noted cites to Proffitt's test 80 with 4:10 gears, a GM 6L90e transmission, and what look like 33s (but I don't see tire size listed). While not a long-term test, it's still impressive considering the route and conditions.

It is hard to Justify, unless you have some serious trips planned, especially in more remote areas where range is an issue. Also, will these newer engines be able to take sub par diesel or will it damage them? When you start picking up fuel on the beaten path, extra filtration and such might be necessary.
I look at a motor swap as a alternative to buying a new vehicle. If you bought a new vehicle that is similar sized as the 80 but with a more modern powerful engine and more fuel efficiency you will likely be paying in the neighborhood of 50k and still not have the offroad ruggedness of the 80 and will depreciate in value every year. By doing a motor swap you are renewing the 80, which will give more power and fuel efficency, and a motor swapped 80 will for the most part retain its value far better than a new off the shelf SUV if the swap is done well. And likely you will be under 50k by quite a bit. Choose wisely though at your choice of motor, you don't want to do it twice. For example, the last 80 I had sold I initially bought from a guy who was tired of the poor fuel effieciency and didn't want to catch up on all the repairs it needed. It had 37s, bumpers and sliders, lockers-the works. He could have dropped it off at a cruiser shop and had a motor swap done and had it all freshened up for 30 to 35k. Instead he sold it to me for 6k and bout a 50k tacoma from the dealer.
Bump! Any updates on the outcome of this project?

I know Tor has developed a kit for the 60/62, It would be awesome to see him work his magic for an 80.
I was up there a few weeks ago at his shop and saw a 60 conversion. It was beautiful. The guy I was speaking too (Ryan?) thought the 2.8 lacked the power for the much heavier 80 series.

I’m holding out for something that starts with a 4
has anyone put a 2.8r in a 62 or early 80 that had a 3fe and a a440f WITHOUT swiping the transmission, I'm interested in doing this, and I'm thinking the a440f would be perfect for the 2.8r since the redline is the same as a 3fe, except the 2.8r has extra power and torque, and apparently really good gas milage in an 80, so imo this could potentially be a really good combo,
Well I started pricing out the conversion, and with a new transmission mounting plate, and a bunch of other extras required I did the math and realized it was probably a $20,000 conversion on the low end. I sure loved my 80 but When the motor died, priced out a bunch of 5.3 swaps and of course the 2.8 option, which would have been super sexy, but a no-go in California as far as I know still. I ended up buying a clean 100 series. Not as good of gas mileage as the r 2.8 probably would get but couldn't really justify putting $20k plus into an 80, not including all the other fun stuff I wanted to do with it.
I still really want to do this in a pre-smog vehicle, If I can find a clean fj40 to put on an FJ80 frame, This would be pretty fun, and probably worth the investment.

Delta Vehicle systems did this in an 80 series, can't remember if it was an a442 or an a440 though

Thanks
, is that adapter for sale on your website?Also how was the drivability and fuel economy?

it is not, we actually haven't really had ANY demand for it so it's on a "as needed" basis. email info@deltavs.com to discuss.Thanks
Also how was the drivability and fuel economy?
Drivability is hindered only by the engine and the EGR system. You can unplug the EGR (and live with a constant "check engine" light that locks out the diagnostic gauge) for better drivability, but that is obviously not recommended. The transmission works quite well with it though! On the Cummins Cruise around the northwest in 2018, got ~26-28 mpg at 80 mph on the freeway with General X3 35" tires and stock gears (and that is with non-stock injectors too for a little extra oomph).

Or you could just move out of that insane State (as so many are doing) and then be able to do what you like to a much greater degree.
Love to see someone drop a Ford Barra 270T inline 6 into an 80 series.

8.7:1 ??? What'd they do, put an injection pump on an old air-cooled Volkswagen engine??
Can't wait to stick a common rail Cummins in something (other than a Chevy S10).

The barra is a nice, smooth, torquey engine. I've seen a few cruisers and patrols around with the barra, seems to be an adapter available but i don't know who makes them. In my experience tho my old safari turbo FZJ80 also ticked the boxes the barra ticked and much cheaper.

You mean put a turbo, DOHC, inline 6 into the truck? I think @NLXTACY has that covered just adding a turbo to the 1FZ. I can guarantee you the 1FZ is a stouter motor than the Barra.... Yes I am prepared for all the internet fighting.
