what is the best bov to replace the stock one.

 

Stick with evo9 metal bov if you arent going to boost over 25psi. Otherwise, id say Tial and turbosmart one. It seems like most people use Tial Q( VTA for Speed density ) or QR ( recirculated with MAF ), but evo9 metal bov was the best decision over any other aftermarket bovs.

I've always heard to stick with the stock one as well.

 

Same 9 metal bov or tial

 

how you doing guys i am new in this but what do you mean VTA or speed density.

 

VTA = vent to atmosphere. It means that the air being released by the BOV simply goes out to the atmosphere rather than being recirculated in the intake system.

 

I use to run a evo9 metal bov with my old green turbo and it held well to 30 psi, but once I installed my BBK-3b it wouldn't hold anymore so went with the forge rs.

 

Stock metal is a good bov, Tomei offers a modified stock bov with a stiffer spring.
Synapse is also very good.

 

Stock like stated a few posts earlier. The metal 9 bov holds up to 25 psi. Save yourself the money unless your boosting past 25psi

 

Question has too many variables. Search.

 

They are so many forums about this..smh!

 

yeah, dont VTA unless you are on SD.
