I have a 92 Sentra SE-R with the BB in it. The car is fast, but can figure out why theres no air come out of the blow off valve after shifts or when i let go of the throttle. But you do hear the peusss...... sound. So my guess is somes wrong with the wastegate or something:confused: Not only that but it also sounds like the air is going right back to the turbo after shifts. But if it does, wouldn't it affect the turbo. Anyone know what i can do to fix this or any tricks that i don't know about yet. Thanks

Are you using a bypass of BOV and how do you know it's not working? It should be getting it's vacuum source from the intake manifold/throttle body I believe or some where after the throttle plate.

I'm still new with the sr20det's. What do mean using a bypass of BOV? The guy that did the work set this up(vacuum hose from wastegate goes into a "Y" tube and one goes into the BOV(stock BB) and the other into the intake manifold.) But in between the "Y"tube and the BB BOV, installed a cheap manual boost controller. Hope you know what i'm talking about.

Thanks,

Sounds like you are working fine....
Check out this thread and it will explain a little about how the intake and turbo setup works on our cars.....
