Hello, I have an F13 with engine damage and have been afraid whether it is possible to install the N63b44b without a big wall (the N63b44a was installed as standard). I have found nowhere else helpful infotmations on this topic. It seems that nobody has ever done this before. What would it take to get the car to run with the newer engine? Have already compared several parts like motor wire harness, ECU, transmission etc. on the Lebmann website but am not wirkli I’d be happy if jemad could help me here. I’d like to thank you very much, Nimo.
