ok i put a blitz bov on my car and it wont work, don't know if we didn't hook up the right vacuum hose to the throttle body or what...the bov is off of an s14. and i have a d15b7 boosting only 5.5 psi. i don't know what's up. but if anybody could help me solve this thanks.

 

do you know what boost levels the s4 was running? chances are it might have the stiff spring for use on applications over 18psi, in which case it would be too stiff to blow off on your car

 

no i don't have ne idea what psi was being used..i bought it off of ebay, it's from Japan..it probably was higher psi than what i have. you think i would be able to find a spring not as stiff for my application somewhere...maybe on ebay?

 

you can call blitz. i think the standard spring is 20 bucks or so. just search around for blitz bov spring

 

Also make sure you have it hooked up to a strong enough vac source off the manifold.

Alot of the nipples off the throttle body aren't strong enough to actuate a BOV.
