well i found this on another post, it may help!

"25526630 and 466748-4 with the code QJ1921P"
numbers off a stock turbo

if u enter the GM number in a google search i found a website with the number TB0348!
guessing thats t3 frame size turbo, 48mm compressor wheel! not 100% but sounds about right!
