Do you mean a pre-spool system for the turbocharger? I seriously doubt it would be feasible, because of the very high RPMs needed for the turbo. The turbo's very efficiency comes from the fact that there is no mechanical linkage to sap energy. Just makes no sense to me. Any future KERS system is more likely to integrate directly in the transmission (and thus no manual transmission option on those cars).
I also seriously doubt they have time to design, engineer, legalize a KERS system in the 2 years left of the E9x M3 production cycle (Euro or US).
