Stage1 Stage 2 measurements

[mark]

can someone provide me with what the measurements are for a StageI and StageII turbine housing. I have one that is stamped as a turbonetics StageI.
I just want to make sure I have a real stageI or a stageI machined out for a StageII wheel.

Size of the turbine wheel (in Inches)

Trim Exducer Dia. Inducer Dia.
Stage I / Std. 1.898 2.319
Stage II 2.122 2.559
Stage III 2.229 2.559

The easiest way to tell if it's a Stage 1 is if there is a decrease in bore diameter as you go in towards the turbine wheel. Stage 2 has a slight lip and Stage 3 has no lip at all.

Not a problem Mark. I have blueprints for these also in case you need exact measurements.
