With a lot of reading and research i still dont know which blow off valve to purchase. I currently have a evo 9 bov with my fp green turbo and the bov is leaking now and making my car idle like crap. Can someone point ne in the right bov to purchase anf where i can get it asap. I dont want a stock evo 9 bov again cause its just goijg to do the same thing and leak again.

 

how much boost are you running? are you looking for a VTA or recirc?

for recirc i recommend the JDM oem valve
if you are running a good bit of boost (30+psi) id recommend the Tial

 

I want recirc i dont want to retune again, i domt want the stock bov because i heard they cant hold more then 24 and will keep leaking. Im running between 25-28psi

 

the JDM MR bov will be your best bet then

 

Also i was told tial would give me a crappy idle and i have my bov right now mounted on my intake itself

 

itll give you a crappy idle because they are vta not recirculative. Only the tial qr is recirculatory.

 

tials only give a crappy idle when they leak at idle. once you get it closed, its fine

what blow off valve are you currently running?

 

where a blow off valve vents has nothing to do with its idle quality

 

Currently using the evo 9 bov metal one all silver not gold like the jdm mr one that i just looked up and its leaking so i want someone that will handle the pressure better can someone send me a link of what to buy so i van just get it. The car is annoying to drive in the morning traffic keeps stalling cause my bov is leaking

you could also try crushing the top of your current blow off valve. that will give you a stiffer spring pressure and its free

 

How would i crush it? And if its leaking already at idle isnt it basically garbage now?

 

you could crush it with a pair of big channel locks

about the leaking at idle thing, i honestly dont know. i been running a tial for years now

 

So if i were to get a tial which tial should i get. Again i need a recir, which im assumijg i dont need to tune for any of these correct?

 

the tial Q is the recirc one.
but remember you have to have the tial flange welded onto your uicp....
