Ok so I have a Garrett t3/t40e 57trim 63. a/r. I wanted to know how to hook up the vacum line to the waste-gate since there's non on the turbo. I heard some people tell me to drill and tap one on the turbo and some tell me to weld a nipple on the i/c piping before the T/b. I'm also gonna run the boost solenoid. Any help would be appreciated.

 

Drill/tap the compressor, drill/tap the manifold are good options. Why not just tee off another vacuum line?

 

i believe that if you connect your wastegate and compressor housing it will eliminate boost creep.
