Would you please demonstrate the calculation on the turbos you recommend? I'd like to see the results and meaning you glean from the results.
Also, Marting will probably not be buying a new turbo. My guess is that these arn't available used??

The "effective flow area" isn't something I can use to fit a turbo to an engine, but it allows me to compare two turbos of different sizes without just guessing.
My T25 comes out at 323 square millimetres
The GT2560 comes out at 430 square millimetres so it's roughly 25% bigger in the turbine.
The GT2052 that Diesel42 is using comes out at 298 square millimetres, slightly smaller than the T25 I'm using.
There are several guys in Aussie running the old T28 on 3.9L Isuzus like mine and they're very happy with the results. But I haven't seen or driven their vehicles so I can't offer a comparison with mine.
