Cracked something on upper intake manifold

Hi guys,
I'm finally in the process of doing the rats nest. As I was taking off my upper intake manifold I broke off this stud like thing a hose was connected too. Its under the electrical thing in the front portion of the upper intake manifold. Here's a pic of it


I circled it green in the picture. Would this be an expensive fix? I already bought speakers and a downpipe for my fd and low in money right now.
Thanks
Andrew

That is the turbo precontrol solenoid.

New it would cost you around 150.
You can find one used in the for sale section for much less than that (~25)

Do yourself a favor and get a highres copy of the vacuum diagram.

If you haven't seen it, check this out. My rat's nest is GONE. No more stock solenoids, no more removing the UIM.

While you're at it theres a couple very good writeups you might want to take a look at.

One is by dale clark and details doing the rats nest vac hose project, the other is by degeesaman and is a detailed writeup on how to test each solenoid and part in the sequential system.

Both are well worth the read.

Here are a few threads about replacing the nipples with tubing.

I know there is another one that uses copper tubing but I can't seem to find it.
