ive never once worried about engine rpms with the 1FZ as long as your truck is in good condition.
the 1FZ will run forever as long as you keep oil in it and pee in the radiator.

Not going to happen, for sure on an OBD2 rig, but believe all of the EFI motors work the same. Not far after red line, the ECU turns the fuel injectors off, until a more sane RPM is seen. Don't know the RPM, was a bit too busy to look, the one time that I did it to mine!
again just to reiterate: if your 1FZ is in decent shape, it can run 4200RPM and more all day long without a hiccup.
Im being serious when i say that the 1FZ just needs a lot of oil and some coolant in the overflow.
I am convinced now that the 1FZ is best petrol motor that Toyoda Industries ever made.
the 1HZ is the longest running engine iteration from Toyota... but its a diesel

huh, did not know that. errr, did not know that was a function of ODB2.
Somehow this has got to be Obama's fault. If someone with an FZJ80 wants to blow is effing motor up, he should, by God, be allowed to...

just tried going up the steep grapevine hill on the i-5 and i overheated past the red with a modified temp guage, i was doing just fine by pulling up this hill in 3rd at 80 mph but i thought i would give 2nd gear a try this time after reading this thread and now im worried about a leaky headgasket soon

A few things:
1) If you were going 80 in third, a downshift to second would overev the engine.
2) Check your fan clutch.
3). Check you radiator.

What was your water temp prior to shifting to 2nd?
What size tires?
What gears are you running?
Also the thread is pull any hill at 65 not 80

If you were able to go 80 in third, then there would be no need to shift to 2nd. You didn't need the extra power. Downshifting when you're going that fast is just truck abuse. Watching the needle go to overheating without doing something about it is, too.
Not sure how long your grapevine hill is, but if it's at all long and steep like you say, I know mine wouldn't be doing 80.

Wait, you kept going even after you know you are overheating? Wat?

My initial thought also. Having driven the grapevine in my truck several times, maintaining 80 is impossible. Going north, if not loaded, you can just maintain 70 in third, if, and a big if, you don't have to slow down. Climbing it heading south, it is a long pull at redline in second, going to third, then back to second as the speed drops.
It's also hot on the grapevine. Over 100 the last week. I'm guessing the poster doesn't understand if the truck is heating up, pull to the truck lane and drop the speed and load while staying in second to keep the revs up. He also probably doesn't know to kill the ac and crank up the heat to help cool the engine in a pinch.
Personally for LA trips I take my old BMW 535i. Better mileage and the grapevine is easily pulled in 5th gear at 80.

After looking at the data for the grade of Grapevine Hill it should be no problem.
The grade in the video (7%) is steeper then Grapevine (max grade 6.7%) although 2 miles shorter an 80 in good shape should be able to pull it at 65MPH with AC on in 100° plus temp.
It doesnt not add up

You are correct. There are multiple 80 owners here who drive over it regularly in the summer loaded and their trucks have no cooling issues. See the early fan clutch calibration threads.
i have been up that hill many times before going about 75-80mph in 3rd through traffic (just did it on friday again my temp remained at 3/4 through the entire way with 90 degree heat outside). the fan clutch is rebuild black hub adjusted and 10k cst fluid. new coolant and thermostat with toyota red, washed the fins on radiator and condensor, JDM aux fan. car runs cool but i may need a radiator considering its original. when it overheated temps out were around 90 degrees and i had zero load in the car and original size tires just have a TJM 2.5 lift. i dont have a digital temp gauge but i was a bit above half mark on temp needle when i started to climb the hill. i was at 55mph when i downshifted to 2nd, rpms were at 4300 at 60mph. temps started to climb and then it settled right at the red a little above it. i turned both heaters on and the aux fan asap. i have been driving the car since that happened and everything seems fine but i just hope i dident ruin something. i also noticed that when i take the engine to a higher rpm it will begin to heat up faster. maybe time for a new radiator as a pm?
EDIT** sorry guys i was not on the grapevine hill, i was on the hill right after castaic lake area on the i5 north, im not sure what its called but im sure its not steep like the grapevine considering i was going 80mph up it.

I drove Minneapolis to Glenwood Springs (through Vail). I was towing too heavy of a trailer and was WOT for almost all of the 18 hour trip. I did burn through a quart of oil between Denver and Glenwood Springs. But it ran just fine. However, the worst spot I think was going East into Vail where the most the truck could do was 30 mph in first gear.
I couldn't believe how durable the motor was. My temps stayed flat the entire time as well.

Too many cruisers, not enough time
That was what I did, and I have never regretted it. They could have come out with a special edition of the 80 series and kept making them for another 5-10 years alongside the 100 series, but with a 2UZ instead of the 1FZ-FE
Old thread revival...
Thinking of installing the Sumo gear underdrive in the Tcase. 93 FZJ80, stock axle ratio (4.11) and 37 inche tires (rubber overdrive). If the underdrive reduces the final drive ratio 10%, the final drive changes from 1.0 (stock) to 1.1 (with underdrive). Plugging those numbers into the grim jeepers gear ratio calculator Gear Ratio Calculator reveals the following: The speed in each gear at a given RPM is shown below. The first screen dump is the stock Tcase gears, the second screen dump is with the underdrive gears. The RPMs I've selected are 750, 3000, and 4200. The question is, at 4200 rpm (max torque of the 1FZ according to Tools R Us post #21 on this thread), the truck travels slower in second gear pulling long mountain passes (like the one LCP did at the start of this thread? So the Underdrive will make the truck slower (7mph slower at 4200 RPM in second gear)? Or do you tend to just rev higher? Any opinions on experiences with Tcase underdrive on long hills? I'm probably over thinking this. Thanks and take care out there...

With the 10% and 37's it should be close to the same as me with 35's

Same hill as in post #1
This time 8 years later when I turned 200,000 about 1 year ago
Today 215,000 and it still can do it all day long
