OP asked about this particular car, and oil starvation in the heads due to the boxer layout. In this case it just isn't going to happen. If you've got a heavily modified car in extreme circumstances you can get oil starvation... in the crank. Real world is just never as simple as a single force.
So as mentioned earlier by evan, a stock FRS/BRZ isn't going to get oil starvation due to hard banking.

Sorry, but it purely about the Lateral G-force and the RPMs.
It has zero to do with HP, EXCEPT - that High HP engines require more consistent oiling due to greater forces within the engine (which has little to do with lateral G-force)
So High HP engines are more susceptible to oil starvation.
Back on topic: IF you have oil starvation issues (you probably wouldnt know it unless you have an oil pressure sensor and log the data), then the solution for racers is an accusump.
If air is ingested by the sump pickup, the accusump will "burp" extra oil to keep the pressure up until the bubble clears the system.
Of course, the accusump can only do this for a few seconds, so a long sustained curve could still cause starvation.
Of course, the BEST solution is a drysump system with a resivoir & dual oil pumps.
