not to distract people from the Boost discussion, this same article has this info about n52 displacement/stroker posibility:
“Only a marginal increase of the displacement is possible (for the I-6 engine). However, an increase is not planned,” Welter says. “This is consistent with our Efficient Dynamics program and philosophy, which improves performance and at the same time reduces fuel consumption.”
so 3.2 n52 means no MPG
