Turbo inlet pipe help

[wrx0131]

i popped my hood earlier today and found that a line coming out of my turbo inlet pipe was capped off by a screw....does anyone know where this line is connected to??

Looks like line 4 to me.



Line 1 plumbs the compressor housing to one end of the T-fitting. This line contains the brass restrictor pill.

Line 2 plumbs the wastegate actuator to the opposite end of the T-fitting.

Line 3 plumbs the middle of the T-fitting to the wastegate solenoid valve.

Line 4 plumbs the other side of the wastegate solenoid valve to the turbo-inlet pipe.

The fact that you have an after market boost controller probably would have been relevant information to include in your original post.
In that case, I would guess that the boost controller you have doesn't need that line. But, I don't know anything about installing an after market boost controller, so......
Why don't you just ask your mechanic?

lol i dont want to take my car to him for that stuff because i have alot of aftermarket parts and i dont want anyone messing with my car.....i took it to him to get a little sound checked out and it was fixed but in the process he removed a bunch of my stuff and then put it back on.....i already had to fix my radiator overflow hose by myself.....and now when my car is cold when it starts up and i give it gas when the rpm returns to idle it drops to like 400 rpms before returning to normal.....sounds like a leak or something......i had the same problem before and i took it to dynoflash in connecticut and they were able to fix it and now it happens again....thats why i dont like just any mechanic messing with my car.....i live in NY so its hard for me to take my car to connecticut because i need it for school and work
