What Bov To Get? Plumback Vs Atmo Vs Semi Plumb?

[Suspense]

MY current BOV is a GFB one, and is a bit shit as it stays open and the spring tension is stuffed, causing the BOV to stay open on idle and accelration sometimes, hence I want to replace it.

Now i am not to concerned about retaining the sound of atmo venting.

IS a plumback substantially better over a atmo venting, from purely a performance perspective?

Furthermore is there any noise emitted from a Plumback? is it at all similar to an atmo venting sound, just lesser volume?

Finally what would be the best Plumback BOV to get, i understand this is fairly objective, but opinions are welcome...

cheers

most people argue that one of the best plumb back bov's is the stock one

a set of GTR BOV's is the way to go, no question about it

how do you go about fitting the gtr blow off valves to a gtst ,does it mount in the factory location

[Sambo33]

would you try & install both GTR Bovs or just one?

[GtstCoupe]

just one i think, would you need two, i have never seen a 33 gtr valve before would be interesting to see how they look in the gtr to get an idea.

GTR's have a twin setup.

But, you can use one of them if you please, its requires small mods i think to fit into a stock R33 spot. But when they are so cheap to buy in the first place fitting costs outweight aftermarket ones generally.

I used one of thw two on my pervious setup and it was more than adequate for mine without drama (Search if you wanna know more)
