So lookIng at the second picture with my sexy legs, which hole would it be? Thiers three. The single hole, is not drilled all the way, so im assuming its one of the two that sit close together. Im running a tial wg, i have a good idea how to run it all, i got ss braided lines for the hot side to connect to the solenoid.

 

The hole you have your fitting/line screwed in to currently on the compressor side is the boost reference port (the one that goes to your WG/Boost controller) the one next to it is for a turbo shaft speed sensor, if you're running one.

I have an older borg housing that didn't come with a pre drilled/tapped boost reference port like the new housings do. If that hole you've got your fitting/line in currently isn't drilled all the way through, you've probably got to punch it out, Not everyone will source boost off the compressor housing so it may need to be opened up to be used.

 

Okay so i need to punch it out to connect the waste gate! Got it man, whats the best way to punch it out?

 

This is what you're after:

" The standard SX-E compressor housing has a 4” inlet ported shroud and a 2.5” hose style compressor outlet. The integrated speed sensor and pre-machined boost ports come standard. However, these ports are not fully machined and Borg Warner does not force you to use them. If you want to use them, simply drill and deburr a ¼” hole through those features. Simply put, these features are NOT boost leaks if you decide not to use them. "



IF you're going that route, make sure you take the compressor housing off the rest of the turbo when you drill it out, and be sure to clean it thoroughly

 

Makes sense, ill use a 1/4 drill bit, thanksthanks bro, its been over a year. Ill do it this weekend
