GT3071 vs GT3076
When I was looking into upgrading turbos, I was curious to compare compressor maps between GT3071 and GT3076 but couldn't find any that were superimposed. So I made my own. Just thought I would share it in case others might be interested as well.

The real life test is better then the paper drowing in my opinion. also this will work good for some applications but it might not work for you.

Interesting thanks. Peformance wise GTs seem to perform better than Alpha's based on 60-130 numbers. Is it the turbine side/housing that makes this difference?

I find my 3076 with external wastegates very reliable and the car drives quite normal at partial throttle. My new LWFW setup now has the response of the turbos coming on faster I feel.

There is also some size difference on the compressor wheel
