Again they're only guesses, and 4th-6th are tall based on the video showing a somewhat tall 3rd (I initially had 3rd-6th all shorter before I noticed 3rd was on the video).

my car has less hp less tq and its drag ratio is .32 and i can hit 150
more tq and hp with a drag ratio of .27 should hit 150 prob topping out after 2-3 miles at 160-165

I previously read that it would top out at 140 (presumably due to a governor). I've since read top speed reports of 140 again, 143, and 136 (that last number supposedly due to fuel cutoff, which doesn't make sense to me).

I'm sure that's part of it, but to be fair they said they interviewed enthusiasts at track days and autox, who may have asked to be able to go above 60 MPH in 2nd (can be advantageous for autox).

FWIW, I based my guesses on cars like the RSX-S, which (according to what I read - please correct me if these numbers are wrong) hits redline at 40, 62, 86, 114, 142, 178 MPH. Because the video shows 3rd's redline speed as being ~1.5% higher than the RSX-S', I set 4th-6th to also be ~1.5% higher than the RSX-S'.
Note that the RSX-S's gearing is still taller (since it has a higher redline). Also the FT's jump from 2nd to 3rd is a bit higher than the RSX-S' (~42%-45% vs ~40%).

It is? Why wouldn't you upshift to 6th? (this car should make enough power after upshifting to continue accelerating)
If the engineers were using 5th to determine the reported top speed of 220km/hr, that actually explains the discrepancy (and would mean 5th tops out at 136 MPH). Yesterday, I asked @EdLoh about that:
@EdLoh Hope everything is OK in Japan with the quake. Back to the BRZ, is it possible they meant 220 km/hr is its top speed in 5th gear?
@deslock I'll ask and then you'll be the first to know. Likely that my Twitter dump could put the kibbosh on any more detail tho.

I added it to the original post.
