I guess that depends on the size of your protein. You should have enough lipds such that the protein doesn't interact with its preriodic image. 90 POPC seem to be a bit to few for that. In my aquaporin simulations, I usually had something like 270 POPE molecules, but if you simulate a smaller protein, less lipids may be sufficient. You may also want to use a hexagonal box which will allow you have less lipids and water.
