well obviously the major differences in those turbos are the compressor wheels.

the 60 trim is larger than the 50. If you want exact numbers I dont know them.

Drop Ben k a line he is awesome with this.

First of all, what are your goals? That will make it easier for us to provide you with information.

The 50 trim compressor, for those compressor map junkies out there, is rated at 49lbs/min while the 60 trim is rated at only 50lbs/min. But, the 60 trim is an off the shelf garrett unti so it is a bit less than the 50 trim setup, provided you are wanting the stage 3 turbine wheel. I've seen cars with either compressor run in the 10's.

Yes, what he said.

The more efficient islands on the 50 trim extend further than the 60 trim. Basically, the 50 trim is more efficient at the pressure ratios commonly used under daily driven (pump gas) circumstances, however the 60 trim flows a little more mass.

Also, if you "spool" a 60 trim to quickly in a tight housing, or use too small of a turbine wheel, it will surge.

Basically under 25psi of boost a 50Trim will make more power on pump, above that on race gas the 60trim is your turbo.

do both have the same spooling characteristics or the 50trim spools quicker ?
