the v160 alone is several times the entire price of an r154 + r154 adapter pieces, and the r154 is known to be friendly to abuse well up to the 600hp mark and a good trans to drift with.
If you happen to find a way to break an r154 at the track, you can find a quick replacement and drop another one in as the trans is not that expensive and you already have all the extra parts.
I don't see a whole lot of 600hp 1uz's rolling around, but if you have one then yeah a v160 would be a good idea, but it will cost you several times more and you still need all the adapter parts.
After all that initial investment if you smash a synchro or break something on mis-shift or clutch kick throwing your car around, you are in another expensive situation of tearing into a getrag or replacing it.
the 350z transmission is interesting, but no one knows how much power it will hold through the adapter plate setup or the super thick flywheel. also the shifter is not coming up in a great spot.
T56 is interesting also, but not a whole lot of progress on the 1uz to T56 front that I know of.

The CD009 350Z transmission might be inexpensive to buy upfront but I have yet to see anyone actually bolt it up into an SC and drive with it. Anything is possible with money but it makes more sense to use a relatively inexpensive solution that already takes factory parts associated with your car or a close relation.
Of all those alternatives, the V160 has been swapped into a good handful of 1UZ SC400's. The engineering and how to support for that already exists but it does take more work and the cost is considerably more than an R154.
Couldn't have said it better myself, the r154 is toyota's turbo 5 spd trans. people have been drifting it for decades now. no need to reinvent the 5 speed transmission that can handle spirited driving and for the most part fits right into your car.

the cost of a normal r154 swap plus all the 1uz adapter pieces like custom flywheel, bellhousing or adapter, and other little stuff. basically every part exists already made by toyota except for the manual flywheel and the bellhousing. some guys in the phillipines make a cast bellhousing that looks almost like it could have been made by toyota that will mate the 2 together with a toyota fork and slave cylinder. the other option is an adapter on the auto bell housing, but requires the use of a hydraulic throw out bearing which is more of the domestic style of doing things.
even if you go 1jz or 2jz with r154, you will be spending ~300 on the soarer bellhousing, so the real extra cost is going to be the flywheel and miscellaneous items.
