Last October my fan quit working on a road trip. Tested stuff at home: Fan was good, relay was good, my wires were all good, but the signal from the Cummins computer to the relay wasn't happening. Don't know if it was a broken wire in the OE harness or the computer itself, but I replaced it all...

Great news! This post in a thread about overheating SBCs that just happened to get bumped recently made me realize that moving my radiator back meant that air was going around it instead of through. So I made this thing Which pulls air from the hood opening, and doesn't let anything get over...

Last winter I had to take the front apart to fix a power steering leak, and while I was in there I cut the intercooler mounts down significantly. That helped by about 15 or 20 degrees on normal days, and 10 degrees on hot days like this summer has been. Also on one day this summer I tried just...

Tires? My FJ40 had some over 20 year old 12.5" wide mud tires, and it behaved like that. Put new 10.5" KO2s on with no other changes and it was like a whole new truck. Of course, then I added a rear lock-rite and it's back to being like that, but at least I expect it and am not worried about...

I like it in my FJ40 at 4,000 lbs, but when you get the whole family into a 100 at 6,000 lbs, that's not going to be a good time. Because here in the Amazon Age, "Add to Cart" and have a new engine with an instruction manual show up in a week can be a lot more attractive than researching all of...

The r2.8 is made in China, so that's not cool. Based on the isf2.8, so even though it's a newish motor here, they do have some history. There are a bunch of them in Australia, and the most legitimate gripe I've read is that supposedly the oil pumps are known to quit around 70 or 100,000 miles...

Yeah, but there's also something psychological that I can't ignore where at 10 mpg, I didn't ever want to drive an SBC FJ40, but at 22 mpg the diesel FJ40 is now my favorite thing in the world. Even if it takes 80,000 miles for that to pencil out, it changes the fact that now I do want to put...

5,000ish mile update: It's good. I added the block heater in January and have been daily driving it since then, and it's very fun to drive. No issues with the motor or conversion stuff. All of my problems have been related to "It's a 45 year old project car" Original radiator leaked, got the new...

I'm kind of curious too, links that might work: High-Quality, Efficient 1hz engine for Vehicles - Alibaba.com - https://www.alibaba.com/showroom/1hz-engine.html specifications are a little sketchy displacement is probably correct, might be a V8 1HZ though 4.9, 4.6, whatever it takes

But really, mine's not as bad as it could be. R2.8: quiet NV4500+one piece TC: Not quiet Carpet inside on the floor: quiet 20 year old mudders bad, new BFG KO2s way better Trying to cruise faster than 65mph: I don't Sound comes in through the firewall so I always have the windows open so it can...

How sure are you that your front driveshaft isn't bottoming out? Maybe remove it and test drive without.

Cummins themselves offer an aluminum oil pan. I think the biggest reason to get it is if your front driveshaft and oil pan want to be in the same spot you can cut and patch the aluminum one. They went with plastic for noise and it seems to work, the motor is very quiet IMO. I've only got 1,000...

Shortened the interior Cummins wire harness in a few places, mostly the warning wires, and OBD reader and the tach. According to the Youtube videos you're not supposed to shorten the throttle pedal wires, and the Murphy gauge is on the far left of the dash so I didn't need to touch it. This...

Second fill up this weekend. 240 miles on the odometer, plus about 25 that happened before I figured out how to make the odometer work. Tank took 12 gallons. 265/12 = 22 mpg. So that's cool, especially considering I was warming it up for 10 minutes twice a day to drive 10 miles to work and...
