Turbine housing delima

[S3.2]

I wonder what is the real world difference between say a Precision 6057 with a .82 turbo A/R and a 6062 with a .63. The same with a GT3582 with .63 and an ATP GT3082 with a .82. They seem to flow the same and they should have the same spool.

Not sure, still learning. Maybe some one will give some good info.

Your thread topic and question have contradictions, you're comparing different turbine housings with different turbos in them. Generally the bigger exhaust wheel in the smaller housing will perform better on a GN.

Second, you'll need to search the import world to see how those turbos react to the same platform and see their true spooling traits vs each other. These boards have very few who dyno and do turbo swaps on the same day, vendors included.
