Does anyone know if it is possible whatsoever to put an 05 or 06 M5 engine into an 05 525i? The 525i is a pretty large car, but somehow I doubt it has space for the v10 considering it currently has an inline 6....If anyone has any ideas, let me know, as I'd LOVE to boost the horsepower of my 525i. Also, does anyone know anything about smartchips? I don't think one has been released for my car yet...
Thanks
