i wish it were ITB's instead of valvetronic though... such a nice sound

wiki tells me new valvetronic engines also use DI. just not the N52, no.
I've read that the n52 has Valvetronic and not DI because they could not fit both into the cylinder head. (Which is why I mentioned them both together). You're definitely right about the Valvetronic not having anything to do with the fuel injection, it adjusts the valve lift.

Thanks for the replies!
