Tom went with that housing because he figured the larger inlet of the T3 housing would be better, but wanted to stick with the smaller T3 .48 A/R size for his low CR 1.6L. But I've heard the are pretty much identical as far as teh ratio is concerned.

:S
i was thinking that too.
i NEED to convert my 92 over to sequential or im 100% going to run out of injector. what about fuel pumps... when do the stock ones tend to die? the FAQ just says PSI not horsepower they support
i have a dyno tune day setup for the first of the month too.
Sorry for de-railing this thread...
i will start a build thread shortly.

I don't think doing sequential gives you any more head room.
Fuel pump, guys use the stock one to 300 wheel plus on gas. I would think if you are above that, you've got serious money in your motor, a new pump is very cheap insurance considering the age of our stockers.

There are 3 compressor trims 48, 52 (Sav's) and 56.
The 48 appears to be a nice size for a 15 psi street setup:
52 trim:
Note that the 48 trim's max efficiency point is closer to the miata's peak torque in a 15 psi setup which would be around 250 hp / 25 lbs/min.
The 52 trim would be better for a track setup because the max effciency point is closer to the powerband peak (~280-320 hp)
The GT2860RS may be better at lower boost because its max efficiency point is closer to 10-12 psi and is probably better at spoolup at lower RPm because it's more efficient in the 5-10 psi range and lower flows:
There is a small trim GTxx60 - 55 trim which would be good for a lower power setup:
which is pretty close to the GT2560
