Is the 100 series really more reliable than the 80?

The A/C compressor bolts holding the fan bracket on disagree.
after doing a couple 2uz timing belts it got easier but i still think there's a lot that could be improved on there. To me it's part of the price you pay for having a powerplant shared across multiple platforms vs a mutually exclusive engine+chassis duo like the 1fz.

I personally didn’t have a problem with those bolts.
 
Reliability? The 100 series looses by a lot in my mind. Starter in the valley is a terrible idea. The electronic booster is a ticking time bomb. Then you have the globe hydraulic suspension system where the globes go bad and the struts leak. Vvt cam seals are a pain. The 2uz has pretty weak rods so it can't handle much abuse. It takes up a awful lot or real estate for the power it actually makes. One cool thing is the 100 series had night vision though. I also wish the 80 had a telescopic steering column but that's also something else that can go bad on the 100.
 
Never had the fortune of owning a hundy, but have managed to put some 30k miles on two 2uzfe Toyotas (4th gen 4r & gx 460). I love this v8 and it feels even smoother than my 2014 LC. Didn’t own either 2uz trucks long enough to credibly speak on reliability because there were no issues in the first place.

My 80 did require a head gasket job, but then it’s by far the oldest and highest mileage vehicle I’ve ever owned by some margin.

A lifted 100 on 35s looks awesome. To those who own both the 80+100, lucky you!

GX460 doesn't have a 2UZ. It has a 1UR-FE
 
I agree with others in this thread that both are very stout, and it's important to understand the nuances of both, get ahead of the weak points so you'll have no issues down the road. Nothing worse than having a car you love continually break your heart because of mechanicals.

Between the two, yes, the 100 is more complex, but I find there is just a bit less headache when working on it. I love my 80 to death, but every time I get back in the 100, I'm reminded how good the steering is, though we all know that's not what the 80 is all about.

Well some jobs are way easier on the 80, like the water pump and starter for instance. Power steering and some coolant hoses are a PITA though; not sure about the 100.

I test drive an LX470 a while ago and thought the handling and ride was actually far worse than my 97 was. I’m guessing it had a worn out rack and bushings, the former of which is supposed to be a real hassle to replace.

I do suspect if they’re both in prefect working order, the 100 would be the more refined vehicle, maybe even more capable with ATRAC and/or a locker vs. a K292 80, but the older Cruisers are better at limping, and perhaps more tolerant of neglected maintenance.

I drove a colleague's 100 several years ago and found your last sentence to be the case. Nothing is wrong with my 80, but the 100 had better acceleration, ride and handling. Both vehicles are unmodified. She later offered it FS for $5K, so someone got a good deal. I probably would have bought it if I didn't already have an 80, although for my preferences I consider the 100 series a bit too modern/refined. Steering rack in a Land Cruiser? After 40 years of SFA with an inline 6 engine, Toyota decided to go "another direction".
Which one is more reliable? Can't say. No doubt they both score high in this category.
 
i've owned both -at this point several 80's and 100's and the 80 is truly from a different generation of Toyota build quality.
The 100 wins all day long in power, comfort, climate control, and safety .... but the 80 is just a simpler machine - and therefore more reliable. I also believe the 80 can tolerate much more neglect than the 100 can. One is not better than the othr, they are simply apples and older simpler apples
Agree.
I have a ‘97 80 series and a ‘99 100 series both have been pretty bullet proof.

...Have to say I love the 80 platform, it still feels like a Landcruiser.

...[the 100] It’s a little quieter and more comfy than the 80, but if I were heading well off the beaten path I’d chose the 80.
Samsies.

This!

I have both. Love both. Drive both. I use the 100 to go to Baja. I use the 80 to "wheel" trails. I wish I could buy a brand new of each of my rigs and do it all over again. I love them.
 
I just bought a 100 a few months ago. It's an 01 with 300k on it and I absolutely love it.
IMO the 100 excells where the 80 fails and the 80 excells where the 100 fails. They are perfect compliments to each other.

The 100 rides super smooth on the road and has enough power to get things done, especially compared to the 80. Of course the 100 is nowhere near as good off road without serious mods and even then the 80 will outperform off road. They both get s***ty mpgs so that's not worth comparing. As far as reliability I don't feel like I can speak to the 100s reliability yet but the 80 has put up with all of my abuse and always asks for more. The 100 has more miles but also had thousands of dollars worth of dealer service receipts in a box when I bought it.

I love them both for very different reasons and I hope they both last forever.

Being the maniac I am, I replaced every rubber component on both cruisers, in addition to shocks/dampers when I got them. Interestingly, it made a huge difference on the 100, and much less of a difference on the 80 (though still noticeable). It was definitely an easier job on the 80. The frame side lower control arm bushings on the 100...😤

I've owned 2 locked 80's and 2 100's. Still have one 100 that is strictly a Moab machine/ski season machine. I've done all of my own maintenance so I would not say one is more reliable than the other. I try to catch things ahead of time as well. I've replaced all 4 radiators as preventative when they starting looking brown, for instance. I miss the lockers when I'm in Moab but I'm likely adding those to my 100. Still has IFS tho vs SFA of the 80. As has been said many times, a 100 with SFA and triple locked from the factory would have been the ultimate. The 100 is much more comfortable to drive and happier on the highways/mountain passes. Just my .02.
 
I have both a 98 100 and 96 lx450. The 100 feels and drives like a more modern vehicle but the lx450 feels more robust.

The 100 has around 330k miles on it now and has only needed coilpacks and plugs because of problems. Everything else has been preventive maintenance, except sunroof leaking err. The lx450 has 221k miles now and had the head gasket done around 185k, and some brake calipers replaced because of problems. Everything else is PM or modifications I've done.
The 100 series is all stock and is what we take on road trips for the room to pack luggage etc. It has better power in every way over the lx450.
WITH THAT SAID I would not choose it over the lx450 for the type of trails we have on the East Coast where muddy rocks and roots jar the hell out of the driveline with traction to slipping and back again. The solid front axle will just take that type of abuse better than the cv and torsion bar setup. Plus the added articulation up front keeps the wheels on the ground better. When this 1fz dies I will be ls/lt swapping it for the power and then I'll have the best of both worlds.
 
100 series for soccer mom stuff and possibly overlanding, and if you want to play on rocks, 80s is the only way to go. There are far better platforms for IFS nowadays over the 100s.
 
I bet the reason why the 105 only came with the 1hz or 1fz is cheaper to manufacture and the ease of maintenance in the field. Maybe reliability too I don't know.

An 80 with the 2uzfe from factory would be the ultimate. 100's slab-sided body was never really a looker nor the Camry swoopy interior.

The ultimate ultimate for me would be a brand spanking new LC 70 GXL here in the US of A. Sometimes I peruse the Toyota Australia site and build one out. lol
