Re: sc61 trim size
We would need to know which sc61 (sc61xx?) to tell you the turbine trim ratio as well if you wanted to know both compressor and turbine trims.
However on compressor side only, I believe they are a 56 trim.

Scroll down to the first section about calculating trim ratio in the above link if you want to know how to get to that answer.

Re: sc61 trim size
Once again, like the link in the above was posted, a larger trim doesn't necessarily mean a larger wheel for the turbocharger. The only time that holds consistently true is the 50/57/60 trim argument, and even then that is simply the for about a 20whp difference, so don't use that argument w/ the SC61XX. the differences are in the EXHAUST wheel for that series turbocharger, not the compressor wheel.

Slight sidenote since it relates to your post. Seems very common people make assumptions like this or also its seems like it is becoming very common to see people mis-using terminology, IE... like saying trim instead of a/r. So they start calling these 70 trims all the time because they see the .70 a/r compressor cover stamping.

"e" compressor cover... 3" inlet/ 2" outlet
"s" compressor cover... 4" inlet/ 2.5" outlet
"sp" compressor cover... ported inlet "s" cover... 4" inlet/ 2.5" outlet
