well i'll be running twin single turbos

so would the split in the oil feed line act as a restrictor?

I would think it might possibly drop the pressure a little, but I don't think it would drop it anywhere near enough for the turbo. If it did, that would also mean your overall oil pressure on the car would be lower as well, which you would not want. Something you will want to dig into, and speak to some one that is a qualified rotary turbo expert. I am certainly not.
