Is it a bowl or spin on? I’m using a shorter one on my 12v because I ditched the wif sensor. I don’t know but I would guess that Cummins uses the same thread pitch on the filters.Now perhaps someone with some diesel swap experience can chime in. I dont seem to have space for the massive cummins fuel filter assembly. Until proven otherwise I am going to assume that Cummins does not have a shorter filter for me to use. Does anyone have experience with racor filters?
I am thinking that a small racor assembly could be bolted to the old 1fz evap canister bracket.
Can you detail a bit more about the vacuum gauge method?I work on diesels for a living so here's my
.02. You should use what ever filter Cummins tells you to use or a smaller one that has the same specs as the original. You should also have as fuel water separator. This will make your other filter last longer and save your fuel pump and injectors. Ideally the fuel water separator would have a heater and and sensor for a water in fuel light. I would also put a vacuum gauge on it so you know when it's starting to get full. I have access to Cummins quick serve and can look up the filter specs for you. If you want to know more send me a PM.
Yes, hence the drive to put a small Diesel engine in a 6000lb 80 seems futile to me. And diesel now and days is a dollar more per gallon.Better MPG? hahahahahaha no.
Less power, more struggle (effort) on the engine, more weight, less aerodynamic, worse transmission gearing... more fuel used.
I would agree and disagree with this, but it depends a bit on intended usage.Yes, hence the drive to put a small Diesel engine in a 6000lb 80 seems futile to me. And diesel now and days is a dollar more per gallon.
Hats off to OP on the project and can’t wait to see the results.
I agree. The Land Cruiser's soul is in dirt touring, and for that, where mileage and range suffer with a gas motor, this seems like a great option.I would agree and disagree with this, but it depends a bit on intended usage.
If your idling down rocky creek beds and trails all day, that engine will dominate the mileage of any gas engine. They burn surprisingly little fuel when idling trails, and the torque curve it will produce is not much of a compromise for that purpose. Even putt'ing down back roads at 30-40mph that thing will just barely sip fuel in comparison.
I have a 4000 lb travel trailer. The 80 chassis handles the weight very well but the 1FZ struggles with the western US trifecta of elevation, grade, and high speed limits, throw a headwind in the mix and I get 4.5 mpg coming out of Moab, struggling to hold 50 mph on 2 lane highway clogging traffic.
My Ram 2500 with 5.9 got better mpg than my 80 even though it was much bigger and weighed over a ton more and barely noticed trailers.
I have been searching for something that’s about 2/3 of a 5.9 powerwise AND quieter (no 4BTs for me).
A lot of people will be disappointed by the MPG of these four bangers.
If you plan on doing this swap for MPG purposes, you are doing it wrong.
If you get 10MPG currently and the diesel swap will yield 15MPG, that's a 50% increase in fuel economy. But, is 15MPG something to celebrate?
In the city a 2.8 diesel will be just as efficient as 1FZ.
Diesels are not efficient when RPM fluctuates. They love to be at a constant speed. Stop and go traffic? Not impressive by any means.
There is no diesel SUV sold new on the market with such a great fuel economy. 30MPG. That's fantasy.Where are you getting those numbers from? Thats pretty low compared to what I'm seeing on the net. For example 25/30 for a jeep on 38's which is double what your quoting.
I would say it's not the stop and go traffic, its the acceleration when the light hits green that sucks it back.
You’re right, I figure I am looking for 3.0 diesel. I keep hoping a shop will figure out how to make the EcoDiesel and tranny ecu and harness run stand alone as is commonly done for LS. So far, haven’t found anyone doing it.12MPG at best?
Anyway, I guess you are looking for a 3.0 6 cylinder diesel.
There are a few choices here.
Mercedes has a few offerings, VM Motori (the same 3.0 V6 found on a Jeep Grand Cherokee diesel), BMW I6 3.0.
With torque ratings from 370 to 500lb/ft those "little" engines are more than satisfying.
You would also need to look into keeping the same transmission they were initially paired up with.
80's transmission is not well suited for the intended gasoline engine it came with anyway.
It all depends on how much money you want to throw at it and what compromises you are willing to make.
I discovered the hard way that the 200 mpg is WAY more sensitive to mods than the 80. I.e. bumpers and tires affect 200 mpg more than 80, which makes sense as 200 mileage gains came from aerodynamics.Those brand new SUVs have 8 speed transmissions, are very aerodynamic compared to the bricks we all drive, are much lower to the ground and low drag and friction tires.
25/30MPG for a diesel Jeep on 38's? Bulls***.
