I have a 96 Integra with a b18 a1 engine swap, T3T4 turbo, greddy blow off valve and it will not open, I have adjusted it soft an it still won't open while boosting an the pressure is going back into the turbo messing it up, I don't think my vacuum line from the blow off valve is right, I bought this bov New because my old one did the samething. Does anyone know about this. Or where the vacuum line is supposed to go.
