I'm assuming they will just upgrade the turbo, similar to the F30 race car we saw a while back.
"Unveiled during the local launch of the newest road-going 3 Series range, the race cars, finished in traditional BMW Motorsport colours and featuring many of the forthcoming M specification components (including brakes, which proved a contentious point come race day) and switchgear took shape over the course of just three months after the ADF Motorsport team took delivery of two road-going test mules that would usually have been crushed after duty. Stripped to their shells, and with an expertly-crafted roll cage in place, the cars use the same N55 twin-scroll single turbocharged in line six engine as featured in the current 335i range. For race application the turbo has been upgraded.
