There's room for a puke tank, if that's what you like to see. You might also be thinking about whether you want a PCV system, do you want a Turkey Pan, etc. I have my
oil/air separator plumbed in directly behind my TP sitting on top of the opening for the breather that is on the back of the intake manifold. Having a PCV system has a couple of benefits for street driven cars. You can do anything you want, just try and decide what it is up front, as that makes it easier.
