The stock N55 engine seems to eventually break at the 600+whp level. Pushing over 550whp on a stock block n55 is most likely going to lead to destroying rods and crank. Correct me if im wrong but there are VERY few n55's out there making over 600whp+. I think its pretty safe to say that no matter what turbo upgrade you go with the n55 will not respond very well to that much power. I currently have a 2011 n55 335xi, FBO ps2 + high flow and port injection. 27psi making 540awhp/590tq and that seems about the most the car can handle |

That isn't enough power? I know, it's never enough. As much as you've spent on hardware, money is not a limiting factor. I know, I have similar. A GTR would probably be more suitable for where you want to go. |
