When you install a Gillis on your tbird, it comes with a cap that screws into the front of the turbo where the little "vacuum block splitter" thingy is right next to the ground wire screw on the compressor inlet. What size is that cap that you have to screw in there? I mean size of the threads. Any ideas? Thanks.

I just took the T out, took it to Discount, and got one that was the same for 2 bucks or so.

Yep, 1/8th out of the plumbing isle. It didn't fix my problem though. Oh well, back to trouble shooting...
