Looks like HKS redid their T04S recently...
http://www.hksusa.com/categories/more.asp?id=1094
You're right...
59mm -> 2.323"
76.2mm -> 3.000"
...which specs out to a 60-1 wheel.

I've got information on the older HKS T04S, which specs out to:
2.301" inducer
2.972" exducer

I haven't been keeping up with any recent turbo tech.
The last time I seriously went looking into it was like 5 years ago.

Turbo names used to have some sort of basis to them, such as their trim size. They also used to follow numeric and / or alphanumeric orders for given sizes. Then it became popular to use their inducer size in millimeters for names. Now, its just what ever sounds cool, and for the last decade or so, anything with a S,V,R, or Z in the name means ubber fast yO! Some turbo names, like I said are given their names by the public (like the GT28RS also known as "The Disco Potato") or creative vendors / marketing people (like the "Blowzilla"). Then there are aftermarket companies that label a turbo (HKS T04E, T04S, T04R, T04Z) that start treads with names (again, anything denoted with those cool letters at the end of the alphabet must be fast). Then Garrett retailers built equivalent turbos to the HKS brand and used the same names (T04R and T04Z) which are pretty close to the HKS badged turbos.

Yeah, T04S not only in the rotary community is assumed to run the 60-1 wheel, but also in the Grand National and smaller 4 banger communities as well (but they tend to run the T04S comp housing, 60-1 wheel, but a t3/t4 hybrid T3 turbine side instead of our full T4).

The T04S/60-1 has remained pretty consistently the same for 15 years or so, but we'll see what other names will result in the next decade or so for turbo names, whatever the cool sounding letters become popular I suppose.

didn't read through everyone's comments, but if you are just looking for 300-350rwhp, why wouldn't you just keep the stock twins? sequential or non-seq, you will be able to reach those hp goals.
i think there's plenty of people that are into the 300rwhp with the proper upgrades and good tuning.
