    If/when someone does a N52 head swap, would there be any relatively simple options to convert the injection from DI and the vanos system? Are there any other systems that would be of concern? My understanding is the DI signal isn't the same type of signal that a traditional injector requires (like those needed for the N52 head). And the Vanos on the N52 has electronic controls. Perhaps this could be disabled? I know it's ideal to use it, but the effort/cost to reward may not be worth it for a conversion like this, and hopefully the head flow would exceed any compromise from having to give this up.

    Also worth noting that the N52 has a metal valve cover.

    See below for the vanos differences.
