Similar engine, but I don't think the turbo is identical. It seems that the housing has a larger 4" outlet (vs 3" on earlier N55's) which seems to make a pretty big difference.
+1 itll easily make 20 hp more than early n55's. Its just that the electronic solenoid cars are still having issues with e85.
