edit. - sorry, sum1 took it. (standard 33 airbox - free).
edit 2. - just found a HKS (copy) SSQV BOV i used to have on my old car, pretty much brand new only been used couple months, and has an adapter to DIRECTLY bolt onto a RB25 (had a custom adapter made at ET).(cost just over $200 couple months ago with the custom adapter). Ill also give the universal adapter away with the BOV, which u can weld into the intercooler piping, so it can fit any car.
$150
