    465 wheel horsepower Stage 3 RMS supercharged S52 M Coupe

    Great build here from RMS (Race Marque Systems) that is putting down some nice power out of the S52 inline-6. The vehicle is an M coupe which was available originally with the S52 shared with the E36 M3 and then later with the S54 from the E46 M3. The M coupe has one of those love it or hate it designs but this is definitely an enthusiasts BMW and it is a shame BMW has not built an M coupe based on the current Z4 as they did with the previous generation.

    I would love to drive one - I am assuming they have a tighter chassis than the M3, and with the lighter weight + all that power? This thing would be a beast to drive in the mountains. Nice job - awesome car.

    That thing is a beauty.

    I was so close to doing a low compression S52 with that blower before going with the S54.
