I got this BOV for free many yrs ago. Well, now I have a turbo motor that I am gonna be using soon. What kind of BOV is this? Is it any good? Can it be used with the stock series 4 turbo or is it too big? I plan to run about 12 psi. I think there may be 2 different springs available for it. The one in it now seems pretty stiff. My buddy is currently borrowing the bov using it on his turbo AE86 corolla (4age motor) with a stock nissan silvia turbo running 7 psi. It seems like the spring may be too stiff as you hear the turbo fluttering momentarilly, then the bov go off.

thanks guys

 

it looks like a Greddy Type R to me

 

unsure, but it looks like an old school GReddy BOV, im not sure though mate, got me stumped...
However with the appropriate kit/welding, i dont see any reason why it cant go on your 7.

Yea I dont know why you wouldnt be able to use it...

 

Yes, it's a GReddy Type-R BOV.  If it has the stock (stiff) spring, it's not going to trigger with nothing less than 20psi.  You'll need to stuff a "std" spring, which should work okay.
