I would add a deeper sump, even a 1/2 qt one, then add a baffle.

I ran a 3.2S for several years in this configuration -- with a spec boxster setup on street tires
with no issues. Had a 100K when I bought it, put 10K miles on it before I passed it on -- mostly
track miles.

The Spec Boxster folks add the third radiator -- and some delete the fans.

I've also seen using the Boxster S taller water/oil exchanger.
