DI + 12.5:1 static CR is not terribly aggressive; other posters have already pointed out Mazda is doing 14:1 static CR with their Skyactiv engine, though they back it down to 13:1 for stupid garbage USA 87 octane.

True but I'm not really talking about a $25k drag motor... I still want this to work on the street

I was also thinking the new B/W EFR turbo might work well. They are twin scroll turbos and they spool remarkably quick and spool efficiently in the top end as well. The biggest thing for me is finding a turbo that will spool by 3500-4000rpm but also flow well enough to not choke the motor at 7k +
