We do not do 60 trim or 60-1 upgrades because of reliability issues, not because we can't, but because we don't recommend it. You can make well over 400whp on a 57 trim CT26. I made 370whp/395tq on a 50 trim CT26, and the spool was fast.

Also, that is only for the compressor side. By the time you spend that much money on the compressor side, and the ammount to get it assembled and balanced you could put that money towards a decent turbo that will actually hold up.
