if you really want the psssht, try full atmo on a hybrid type bov. if it gives you trouble in full atmo (which plenty of skylines run without issue) then go 50/50. you should be fine. if that fails, you can always set it up as fully plumbed.
for the guy that asked earlier how its done:
fully plumbed = block one side, attached other to recirc hose.
50/50 = trumpet on one side, other side to recirc hose.
fully atmo = block recirc, use 1 or 2 trumpets on bov
here's mine 50/50
fully plumbed back, as it is now, . the trumpet is replaced with a supplied cap from GFB
btw, if it didnt come with the car, i highly doubt i would've needed or bought it.
