Hi all, i have a set of BOVs coming but where do i get the bungs from to sort the pipes out or what size are they...cheers!!

Ive just finished exchanging my recircs for a set of apexi's.

 

The pipes are 28mm in diameter and i used plumbers end caps (£7 each from B&Q) to block off the pipes. Like this:

^^ Thats if you are fitting new BOVs in the same place isn't it? Sure if they go elsewhere you need another size too (35mm?)

Thats what im wondering. I have never done this before or even looked at another.

Do a search - s13silvia wrote up about it a couple of months back, but I'm pretty sure its 28mm and 35mm.

Thanks. Forgot to say i was putting them in the engine bay on hard pipes. They are Blitz. On Question is that where does the vac pipe go from the top of the valve. I understand about blocking everything else but what about the vac pipes. Fook me i feel dumb!!

You could use the vac pipe that wouldve run to the stock recirc.

 

The pipe leading to the stock recirc is in 3 sections. Rubber hose from the plenum to a metal pipe (attached to an intake pipe) then another rubber pipe to valve itself.
