I wasn't concerned with cost, they simply are a more no holds budget (though it is still a strong player) in comparison to gas engines for achieving what's being debated....with the diesel talk

As for the BSFC, I had assumed he was speaking purely at peak power/heavy load. Yes, you can actually run turbo applications lean, especially with direct injection.

If looking at an actual performance map (RPM or mean piston speed on the x-axis, BMEP on the y-axis and then having BSFC efficiency islands), things actually used for design, hands down the smaller turbo engine will outperform an NA engine of the same power...assuming we're still comparing 4-stroke piston engines.
