the t3/4 is a small exhaust turbine with a bigger compressor wheel...the bigger wheel also comes in several 'trim' levels where the compressor wheel is machined(?)/trimmed for what I always forget, either to make it slip at high rpm vs heat air or something. I generally have to look up the various A/R (area/radius) ratios for the various turbocharger combinations.
Anyway, any turbocharger catalog or even a web search should give you the differences, and you may even be able to look up a compressor 'map' which gives you the pressure ratio as a function of rpm and sometimes even temperature rise (basically if you overspeed the turbo outside its efficient operational envelope it heats the air more than compresses it).
