• I'm installing a stock TD intake mani and there's not a bov on it. Can I just block the hole or do I need a Bov?
  
  Then if I do need one is there aftermarket ones that'll hook up? Thanks
  
  PS. This is for a vnt-15 install and I have no idea what boost it'll try to do so I think I want a bov in case the turbo goes crazy too easy.

• You shouldn't need one as long as the vanes aren't closed all the time,

• nah you dont need one.
  
  One of the 1st things I did after I got my newest one running was pull that center screw out, drop in a small piece of dowel and screw it back down.
  
  There are people (on here I believe) that have made nice plugs that fill that hole. I have a spare BOV here I could probably send ya if you want it.

• Thanks guys, I'll try it w/o a bov first and if I need one I'll worry about it later. Looks like I'm gonna have to wait untill fall time to install the turbo anyways.
