How to tell stage of turbine wheel??

[zlancer]

Hey,

My t3/t4 turbo (.57 trim 50 a/r compressor, .63 a/r turbine housing) supposedly has a "stage 3" turbine wheel. I need to order the chrysler style turbine housing and I need to know how to make sure it is a stage 3 wheel size. What should the inner and outer measurements of the turbine wheel be for it to be a stage 3 wheel??

Stage 3 exducer diameter = 2.229" (Stage 2 = 2.122")

So the inner diameter of the housing should be about .030"-.050" larger.

for the inducer i got 2.20" and exducer i got 2.57"...soo...what would that be?

The inducer applies to the comp wheel & exducer to the turbine wheel. The outer diameter of the wheel is referred to as the "major" diameter.

What you mean is;
exducer = 2.20"
major = 2.57"
Which means you do have a stage 3 turbine wheel.
