Assuming the 300mm was limited to applications that had boosters, but based in academia, no specific knowledge.
This being an HZJ80 with turbo?
Manual swap on an 80. Opinion on performance needed!!!

Off topic but yes a 1hz with all the turbo components from a 1hd-t. Soon to have a hybrid supra/landcruiser ct26 with billet comp wheel. Will probably need a better clutch very soon after.
Meh....
And they H150F's 1st and 2nd are unpleasant with 4.11s?
Great....
How about the higher gears?
HF1A or HF2A?

1st and 2nd are great for low speed control in low range, amazing engine breaking. Yeah it's a part time dx model with the hf1a.
5th gear is way too low, I don't have a tach but I believe it puts the rpm at about 2650 at 100kph on 33s.
If I had some serious coin to blow I would go to a full time transfer with a part time kit and crawler gears. Then regear the diffs with 3.7s. That should keep a decent low range ratio while improving the high range drive ability.
A more powerful motor (1fz) and rubber overdrive may help things, I only run 33s.
Toyota really could have gone with slightly better ratios from factory.

I countered that with 315/75's so in 5th at GPS 99kph it's just sitting on 2250 in 5th. The V8 manual combo is nice, good fun to drive also and the H151 is handling it well so far. My daily drive is an auto, nice for traffic but annoying when you want go faster it's first response is look for a lower gear. Manual you can surf the torque and load it up. Not lug, load.
And in low first manual with the reduction gears even on 35's the odd dab of the brake is all you need.

Ok Since yall went off topic and discussed different Toyota transmissions (which are not within my reach) rather than giving me input on the listed alternatives above. Lol . I decided to go with the NV4500. I know I said that I already crossed it off the list but while on vacation in Missouri this week I found one for $140 so I guess I'll go this route. If successful, I'll come back and do an R150F as well.
Never seen or drive an H151f or H150f but after meeting the NV4500 face to face I don't think it's too bad of an option. Not that heavy for a cast iron trans. The throw isn't as large as I thought, plus the stick was quite long and the throw wil probably be less when shortened into the LC. Most importantly, I know I can't break it, at least not with the fzfe
So for those who care I will make a post soon when I get back to Texas.
Bellhousing will be built from scratch but I really wish I dont have to takeoff the transmission out to get measurement. So if someone already have on out, would you please pencil trace the bolt pattern and output shaft location onto a large pieces of paper? and one from the full time transfercase will be nice.
Since the NV4500 is a bit shorter than the stock auto, I think I would make a trans-t case adapter to compensate for that length so I can keep the same drive shafts and transmission mount. With supported bearing in it, of course.
Will talk to a friend to figure out a non invasive harness for the ECU to fix the check engine light and cruise control problem.
My goal is to mess with the trans and the trans alone. No other modification if possible.
Can't say anything yet but if you're looking to go down this road with me I think I would be interested in making a few kit. Doesn't cost that much to make a few extra plus to compensate the cost. Let me know so I can plan the manufacturing accordingly.

The diesel guys use the nv4500 quite often. It's tough and I think you'll like the gearing but it's also big and heavy and you might have to do a body lift or cut the floors to get it in.
The Tacoma 6 speed was completed by that one guy and I don't think it went well.
The nv3500 and ax15 are light truck transmissions. Should work well as long as your not trying to pull a big load or compete in king of the hammers or run a high HP engine. I think the only reason you don't see more using these transmissions is there either Toyota loyalists which the h41, h42, and h55 are good attainable Toyota candidates that are much more worth talking about than h151 and such if your in USA. I'm actually considering an ax15 swap because i already have the trans or an h42 which is a 4 speed.

@Chupacabre, the 6-speed is actually extremely fun to drive on the 1FZ. Not sure why you would say it didn't go well, it's a very good option when the gearing is done right.
Anyways, it's for sale, parted out or a complete 80.

Sorry aMiR904 based on what I remember of the build thread I don't remember hearing much about the outcome so I guess I was making assumptions. Shame on me. I was super interested in the direction you were taking with the 6 speed and rebuilt stock. I'm still entertaining options on mine.
