• 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.


      This is a built motor car with forged low compression internals. The Stage 3 supercharger setup produces 16 psi at redline. The car features meth injection courtesy of an Aquamist HFS3 system.

      The modification list and dynograph are below. This is a very healthy and well built supercharged S52:

      • Forged Low Compression S52 pistons custom made for RMS by Ross Racing Pistons

        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.

        I absolutely love it! I would want one in estorial blue or black. I looked for one for a while but couldn't find one in good condition at a decent price and gave up.

        That thing is a beauty.

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

        With a VAC stage 3 Cylinder head on that thing I bet it could hit well into 500 whp range!

        all it needs is the tail lights cut and polished, and it would look 10/10
