soooo, i installed a replica version of this intake manifold. i bought it on enjuku racing and of course looked at some reviews before and they said its work just as same. so my boyfriend and i worked on installing the intake manifold for almost 2 days. changed all the lines, re-did everything to make it look really nice.

now the problem is, when i start up the car, it does NOT hold any vacuum pressure. i went to 0 psi, and we have tried everything looked at all the lines and see what can cause this problem. so i dont know what is going on with my little silvia. if you guys can help me out this is my first car and the first time i ever fixed a car.

1989 240sx Coupe
Sr20DET Black Top E5
Fadanza 11 lbs flywheel
ISIS 3 inch full exhaust
Megan Exhaust Manifold
Greddy RS BOV
FMIC
I just bought a S-AFC II not hooked up yet
and so much more.

my co-worker at work told me it could be that my intake is holding more air.?? do you think that it can air fuel? or something i really need the help!!

thanks in advance.
