what is the best bov to replace my stock one and what mod i have to do. thanks

 

Don't know which Evo you have, but the Evo 9 diverter valve is best if you have not converted to speed density.

 

depends if you have an 8 or 9. if an 8, get a stock 9 BOV and you are set until above 25 psi. if you have a 9,just keep it until you run over 25 psi. dont be a ricer please.

 

Yeah, after doing research on this forum, I purchased a stock Evo IX BOV to replace the aftermarket one that's on there.. Was cool at first, being my first turbo car and all, but the noise gets annoying after awhile IMO.

 

depends on the turbo, I have the Kinugawa and it flutters because of the extra air, so im looking to replace mine.

On my stock 9 turbo the psssh sound was loud and got alot of attention

 

Stock Evo 9 bov best in my opinion
The noise does get annoying after a while if you use your car as a DD

 

like i said in lastpost. get the 9 if you have an 8. i have bolt ons and my 9 bov holds peak 26 tapering to 21 fine.

 

I'm actually running a stock evo x bov on my evo 8 and it works great!!

 

IX and X bov are pretty similar. If you're looking for something more than that, get the Synapse DV or try to find the APS twin vent.

 

Synapse DV has been good to me.

 

thsnks guys for your help. i will looking for one today.

 

Also the Tial QR is being recommended a lot. One of the 3 below for sure.

Stock 9
Synapse
Tial QR

 

^I had the QR also. I would recommend running the low spring pressure for MAF setups, 6-8 psi worked best.

 

you should get the hks ssqv bc its loud and sounds cool

 

The previous owner of my VIII had this BOV on the car, god is it loud. So I gave it to my buddy who drives a genesis 2.0T
