37s on factory gears (1 Viewer)

This. Too many baby the 1fz. It’s a glutton for punishment. Let it eat.

Agreed, OD Off and 2nd are great tools for long grades. I’m on 315’s not 37’s and I’m fine with my stock gears. I’d like to do the TC gears more for the low range but would probably welcome the 4.56 high range.

Without re-gearing the driveability of the 80 series performs significantly worse than on stock gearing and stock tires.

Mine performs pretty good with 37s on stock diffs!

You don't seem to have a good grasp on what the term subjective means.

Au contraire! Have you run 37s? Uh oh! Consider looking up ‘subjective’ in Webster’s or just do a Google search.

Unless you're turbocharged or supercharged your vehicle isn't anywhere close to the same level of drive ability that it once had. Toyota didn't at all program their ECU and transmission control with their design parameters...... clearly you're not an engineer.

Given your stance on this topic and photo I'd wager your 37s likely rub and you've got a system that doesn't actually fully function.

I don't think anyone is arguing the engineering that proper gear ratio creates a better driving experience.

But, the decision that they're good enough is a subjective decision.

You clearly feel that your way is the only way and anyone who chooses else is wrong.

“A gem cannot be polished without rubbing.” Same applies to Cruisers on dirty sevens.

clearly you're not an engineer.

Sounds like something a pompous enginerd would say. Loosen up and have some fun with your 80…sheesh.

Understanding gear ratios isn't engineering. It's basic ****ing physics. He's just being an ass

Toyota also didn't design the 80 to run on 37's, or lifted, or with aftermarket bumpers..... so.... i mean....

don't make the rest of us enginerds look bad.

I never said you couldn't modify their vehicles, hell Toyota modifies their own vehicles as well. Generally speaking you're counteracting those mods with other mods. Lifting the vehicle? You'll need to do a caster correction. Aftermarket bumpers? Stiffer springs. Or just have the 80 drive like s***.

Whatever. You guys do your thing.

You do know engineering is generally the application of physics right?

you're* Grammar ain't our thing. i gotchu.

but then you're speedometer is outside of it's design envelope... and you're engine will be at the wrong RPM for the highway where the engineers did the life cycle analysis... and you're bigger wheels are loading the trunion bearings more than the FEA model alowables... and.... and... .and..... being an engineer doesn't make you better than anyone else, it's not cool to throw that at people. we have a hard enough time making friends as it is.

If you re-geared inline with tire size how would you be at the wrong RPM?

I never made mention i was better than anyone nor do I call him names. I simply stated that the vehicle would suffer significantly without a re-gear and people claim that's not the case. There's no merit to not re-gearing other than a financial one. Throwing things on a vehicle haphazardly results in a vehicle that is poorly modified. You guys are easily offended.

I don't have trouble making friends so......... sorry to hear about that.

You’ve said this multiple times now. Are you implying that we’re poor?

A bar is a great place to make new friends!

Serious question: Do you have to drink beer through a mask if at a bar in commiefornia? I saw a video of some Cali folks making out with masks on, which was weird.

Now that you're steering this to something political I'll certainly see myself out. Good luck with your rig.

You do know that engineering is far more complex than basic physics and that trying to compare understanding mechanical advantage via reduction ratios to engineering makes you look like you think you're ****ing smart, but instead you just look like a douchebag, right?

Because now that rpm is no longer the needed rpm to make enough power to efficiently move the vehicle. You've increased drag, rotating mass, and decreased aero by creating more of a pocket under the vehicle.

I thought you were an engineer?
Do the math, what gear ratio is needed to account for all of this?

I totally agree except in my case having gone through the iterations, I’d skip 35s and go to 37s with the 4.88s. 37s on stock gears is a non-starter.

I mostly didn’t like the 4.88
+35’s freeway driving at higher revs compared to stock (more nvh), but did enjoy less hunting at freeway speeds on inclines. You get used to the little bit of extra drivability pep in normal driving. The 37s brought me back closer to a stock driving experience which is what I enjoy the most given my 1FZ-FE shall remain unmodified.

All the gearing and tire combos discussed move the needle up or down in bite sized increments thus all the discussion. Unless you experience it for yourself, you won’t know what advice to give to your own self because it’s a case of you don’t know what you don’t know. I guess learning from past mistakes is a part of the fun/journey in 80 ownership. You relish the results that much more because you’ve been through the ringer (time x money x wtf).

This thread has turned predictably cringey because of the truth you typed. Similar thing occurred in the do I need caster correction with a lift thread. When people run out of arguments grounded on logical reasoning, it gets lame fast.

Choose your own adventure dude. 🕊
