Stroker from all the research I have done, people I have spoken to, I'm sure Mat Hutchens as well - they all say as close to the intake as possible, ie between the intercooler and the Collector (passenger side for you). A guy here who has built heaps of GTRs and races them mounts his now under the Collector, so it cant be seen and has them free to atmosphere. I have mounted mine on top of the Collector and recirculated it, only again due to local Licencing requirements here, that dont allow free to atmo.
