Can you fit a BOV into a non-turbo car?

BOV's (blow-off valve) are to prevent too much positive pressure from entering the engine due to boost build-up and to releave back pressure from re-entering the Engine. A non-turbo car cannotuse a "BOV" since there is no turbo and/or positive pressure present in the intake manifold. This is STRONGLY not recommended, on NON-Turbo cars. As there is not reason for it to be present.

you can fit a bov but will never hear it working. Without turbo you'll never reach pressure in intake to make it work. So installing it in non-turbo is worthless

sure, as long as the car has a turbocharger, and you source the vacuum/boost for the BOV from the intake manifold.

the BOV is plumbed between the SC and intake mani, to relieve excess pressure/boost. If you need specific instructions as to how to actually do it visit some of the cool import sites and you can see pics of some good homemade jobs and bad.

Because the bov requires pressure in the intake system to work, this pressure comes from the turbo, no turbo on your car no pressure in your intake system to work one.
