Car won't boost at all...help
I was doing partial throttle today and it was boosting about 10psi when I heard a small pop.
I thought that maybe I blew a IC pipe but I checked them all and they are all secure (also have tbolt clamps on everything).
So I thought that since I was running 28+ on my stock turbo that maybe the turbo let go. I took off the intake and spun the turbo and checked for shaft play. Well it spins freely and there is no shaft play.
The car is on the aem ems with map sensor.
The car idles perfect. There is no white smoke or anything odd.
I checked any vacuum lines I could find to see if something blew off but I couldn't find anything.
The car will NOT boost at all. Not even 1 psi. The boost gauge won't go over 0 and it feels like I'm driving a honda civic.

No I haven't done it yet. It happened on the way to work so I didn't have time to test it.
I just figured if it was any kind of leak the car would still boost somewhat.
It doesn't boost AT ALL.
I've blown a hole in a IC before and the turbo will still boost.

Took the intake off and started the car and the turbo was spinning happily.
Took off the bumper and to my relief saw that the IC coupler had a tear the size of china in it. The tbolt dug into it and started a tear and I guess the 30lbs of boost did it dirty!
Sorry for wasting all your time.
Stock turbo for life!
