So, a good friend of mine just finished up his Stage 2 build for his 2018 F80 M3 Competition with Mosselman. He's not done with the car by a long shot, but definitely need to give a shout out to the Mosselman crew for this amazing build. If you're wondering why I'm posting here on an F87 group...obviously the F80 and F87 Competition have the same heart; that amazing S55.
While I don't have the full build sheet, the central component to this setup is the Stage II Mosselman hybrid turbos. If you want the details on the build, below is a link to his Instagram...or you can reach out to Mosselman directly for the recipe to the secret sauce. They’ll get you hooked up.
All I can say is that after riding in this car, everything else feels slow, and now I’m planning my build.

Hit him up with any questions you've got!
