Compressor: T-25, 60 trim 56mm BCI-1 compressor.
Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
Center Section: Journal bearings
These are specs of the S14 turbo that has the larger wheel:
Compressor: T-28, 60 trim 60 mm BCI-1 compressor in T-04B housing
Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
Center Section: Ball Bearing
Same turbine/ wheel size. Larger compressor/ wheel.
Specs on the GT2554 from the garrett website:
Compressor: 54.30mm 60 trim wheel
Turbine: 53.00mm
Center Section: Ball Bearing
Specs on the GT2560 turbo from the garrett website:
Compressor: 60.10mm 60 trim wheel
Turbine: 53.00mm
Center Section: Ball Bearing
It appears that the SR20 turbo is actually a bit larger than a gt2554. It also looks like garrett uses the same turbine/ wheel for the 2560 and 2554, just different compressors/ wheels. Makes sense to me. Larger compressor wheel means larger volume of air will be displaced.

For anyone looking for a cheap T25/T28, I was around 240's before miatas. This one works great and is probably the CHEAPEST you will find anywhere that isn't from ebay.

If you want a 2871 sized turbo the same company makes this turbo as well.

Final edit? - I think these (both links) are journal bearing not ball bearing, fwiw.
