I was wondering if it is possible to convert an n47n engine to n47s since the only difference between them is the second turbo.

I know that there are so many parts to replace but anyone with a clear idea and know how will be appreciated.

no idea, Id have thought that would throw your warranty out of the window though?

This might be a better idea, from BMW themselves,

Check out the thread about the m-performance kit that Touring have installed. The performance should be very similar to a 525d and all warranty will be intact.

Yes, it's possible, but is it worth it? a Remap should bring more power for a lot less money...
