1958 vs taco trdOR

[Jetboy]

It'll be interesting to see how aggressive the torque management is. 465ft lbs at low rpm would make it real easy to break stuff without some electronic nannies.
You going to be taking your 250 through the rubicon?

This sub is awful quiet today....

Agreed. Especially with the 8AT. I think they must be basically the same strength as the LC200 or better. The LC200 seemed to be pretty solid up front. I know of a few blown front birfield joints, but not many. I haven't read of any so far on the new Tundra even with 37's. So the front end must be ridiculously strong or the ECU is holding back quite a bit. Maybe both.

For rough comparison the max torque that each vehicle could send to and axle shaft (assuming only one has traction) is:
5th gen 4Runner 9,344 ft lbs
GX460 11,054
LC200 16,641
The new Tacoma has a max of 18,879 ft lbs * I'm assuming the same for the LC250. It's a LOT compared to the 5th gen 4R.
Land Cruiser 300 Diesel: 21,700
3rd gen Tundra/Sequoia hybrid: 25,064 (I think that's the most of any Toyota light duty vehicle so far).

Just for comparison a stock 8" birfield would fail at 4,200, a 35 spline 4340 Dana 60 axle fails around 12,000. I have no idea what the new birfields and shafts fail at, but I'd bet they're stronger than a 4340 Dana 60 35 spline shaft, but not by a huge margin. Those hold up to a lot of abuse. I'd guess the torque available still exceeds the maximum traction so maybe it doesn't matter after some point where the shaft is stronger than the GVW x traction?

I don't have an order for an LC. Kinda waiting to see what happens and where I end up. I'm in Alaska right now and was headed back to Montana in the spring but decided to stay through the summer at least. I couldn't leave without one more winter in the big mountains and another summer of wilderness exploring. Still need the Tundra to tow all my junk back south so I probably won't trade cars again until I'm back down in the lower 48. I'd like to see what the next 4Runner is too.

But - hell yeah I'll give the Rubicon a go in an LC250 if I get one! If they fit 35s out of the box and 37's as easy to fit as they are on the new Tundra the Rubicon might not be much of a challenge. I think about a 4Runner on 37's plus another 4 inches of travel it would be pretty close to just point and shoot through most of the Rubicon. Only real hang up is the width. Some of the places favor narrowness. I can't help but think with a lift and tires the LC250 will be really capable.

Are you thinking about switching over to a LC250?

I'm about 95% going to get either a LC250 or GX. Leaning towards the 250 for the fuel mileage, but I hate I4 engines, going to have to drive it and see.

More than 95% for a GX OT+. Less than 5% for the 250.

I'm already promised a test drive on the first 250 locally - no relationship with Lexus so I'll join the line. I would really need to love one and hate the other to change my calculus.
