87TSiStock Posted December 27, 2014 Report Share Posted December 27, 2014 so i'm making my own hardpipes out of 2.25 S.S. and on the stock pipes on the hard section right before the T.B. where the vacuum line that comes from the turbo hooks to, can someone tell me what that is on these cars and when you have hardpipes on where does that line reroute too?

creakyjoints Posted December 27, 2014 Report Share Posted December 27, 2014 You can just put a fitting there. It goes to the turbo wastegate. Link to comment Share on other sites More sharing options...

pcristquester Posted December 27, 2014 Report Share Posted December 27, 2014 Drill, tap and install a fitting to the hard pipe to hook it back up like the stock set up Link to comment Share on other sites More sharing options...
ucw458 Posted December 27, 2014 Report Share Posted December 27, 2014 That's the WG hose location. You can have that connection anywhere in the hardpipes you want it to be except the turbo inlet. That hose gives you a boost reference to control the wastegate. Without that you have no boost control. Link to comment Share on other sites More sharing options...
87TSiStock Posted December 27, 2014 Author Report Share Posted December 27, 2014 thats where a boost controller would be put between then? Link to comment Share on other sites More sharing options...

techboy Posted December 31, 2014 Report Share Posted December 31, 2014 Either way you'll need it. As stated above, drill and tap - I'd recommend a 1/8" npt tap and get a barb fitting from your local auto parts store or Summit and attach. Link to comment Share on other sites More sharing options...
