nope, that's their real bov. yes, they do make that stupid NA bov, but they do, or did, make a real one too.

its just a pop-off valve for the air compressor. the Pete's we have at work pop-off at 120psi. and at that pressure it is pretty damn loud. the pop-off is just a tiny little thing too, you'd be surprised how small it is to produce that much sound, but its all about pressure.

a company called night pager made it. i've been searching for it high and low but i can't find it anywhere....i can't find it on their japanese website anywhere. doesn't help that i can't read it (damn it dad, why didn't u teach me?) but i clicked pretty much every link. their usa website seems to have disappeared......i have no clue where you might be able to find it....maybe that takakaira place can locate one for you.

yellow skyline... i like your sig but correct me if i'm wrong. the issue you're addressing is durring driving, when you shift, it's not really the greddy being greedy. it's kinda that the TB closes and doens't let the motor have ANY air for that minute time. so praise the greddy and boycot the throttle body!
the issue people have with stalling is usually at idle. because at vacuum pressure the stock diverter valve remains open and allows air through and back into the intake continuously instead of expelling it atmospherically. adding a BOV very close to the TB while still maintaining the stock diverter would allow that when the TB closes the air is expelled through the BOV quickly and the remaining continuously circulating air that's before the diverter would still be diverted normally (due to vacuum pressure keeping the stock diverter open) for this all that's needed is to adjust the spring on the BOV so that the spring is harder to keep it slightly closed in case any air gets by the stock diverter and ends up downwind by the new BOV. hence the dual BPV/BOV setup. this is relatively harmless to the motor as long as it's done right and it's really actually a lot of work to get a cool ppssshhhtt sound every time you shift but hey, to each hos own. i rather like the ppssssshhtt.
wow it actually makes sense to me now too
