I don't think they're going to bring the air-to-water IC or the twin turbo setup over to the N55B30. I can't see why they'd do that instead of just detuning the S55 and dropping it in there. I suspect the N55B30 will be an N55 with upgraded pistons, crank, oil sump (maybe), and a larger traditional intercooler.
