Thread: Blow off valve options

FYI - Synapse also comes with a recirculation fitting.

is the avenir/bb valve the same as the 1g dsm? As in does it leak for a mild setup

i run a greddy type s recirc in my b13 and my little bro runs the new hks ssqv recirc also.

+1 synapse re-circulated..sounds low key..great for a sleeper set-up

No maf no recir.

tial is nice but the synapse seems like a better quality bov, also a great mechanical design

The stock Nissan BOV is good foor stock boost levels but not much more. The 1G DSM will hold 18 psi (unmodified) without leaking which is quite a bit more than most OEM BOVs which is why it is popular. The stock Nissan stuff is a bit weaker I believe.

i think the synapse is not needed because it over complicates things. Keep it simple stupid is what i go by.

What?! You must have lost your damn mind.

It's STUPID simple. You install it, run vacuum lines, and forget about it. Pretty damn simple if you ask me.

Yah but how many vacuum lines?
