S15 replacement plumb back BOV size

Recommended Posts

Hi there

 

I have a S15 that is still running the stock BOV on a greddy intercooler + pipes

 

I'm pretty sure that the previous owner has blocked it up as I get some rather loud fluttery sounds coming from the pod filter "running 1 bar of boost with a tune"

 

I will be replacing the turbo with a larger item running more boost "20/22 psi" + the associated supporting mods

 

Was thinking it might be a good idea to fit a new plumb back BOV just in case the one I have is blocked off, however I am not 100% sure of what size BOV I would need to get to bolt on to where the factory one is. Or for that matter if its even going to be an issue running a blocked BOV with a precision HP5130 at that boost

 

I was thinking of getting something like this

Seems to be good for skylines but no mention of any SR powered cars

its got a 50mm valve

highly highly doubt you will need any thing bigger then that

 

its basically the plumb back version of this http://www.tialsport.com/index.php/tial-products/bovs/46-tialbvq which is what i use on my GTR
