#109073, "RE: Can anyone help identify this turbo????" In response to In response to 2
if you have a typical T3/TO4E 57 trim with a stage 3 exhaust wheel and a .48 A/R housing, it might have a powerband of 3000-7000, with the .63 it might be 4000-8000
No one here can specifically tell you exactly how the turbo will respond. I can all tell you it will work, but there are a handful of other variables that will determine the exact end result. From the information gathered here, the turbo is in a useful range for your project.
Those links I posted will better help you pick the next turbo for your future projects, and will serve as a reference chart when you finish the calculations that identify your compressor housing.
