I was thinking about a 50 trim or a plain old 20g for a while. I finally got around to crunching some numbers on compressor maps and found that both had points just past the surge lines at 4500 RPM's and lower at 24 psi. But that's just me and the latest I'd want a turbo to reach full boost.
I used an old guide out of SCC, and maybe my math was a little off, but to me they didn't look appealing. Maybe if you go with a late spool/full boost at 5000 RPM or later it might work (.82A/R exhaust housing).
The power would be there at the high end, but as far as what's streetable and what's good spoolup; you make you own definition.
Here's the maps I used;
20g and big 16g (click on the check marks)

I was very impressed with our big 16 map. The same numbers and 24 psi. was in the 68% efficency island with nothing past the surge line.
