BMW Sport

Good evening, I'm Portuguese and I have a problem with my box 6hp26. At this moment my project is in the final phase and I hope to achieve + 400hp. But I would like to exchange my 6hp26 box for a 6hp28 of a 335d e92. Someone here already did it to help me, thank you very much.
A big hug

Hello, unfortunately i think a nobody here did such swap, however it sounds like interesting project.
