When I got my car the last owner decided to bypass the BCS and just hook a line up from the wastegate to the compressor housing, now I want to hook the BCS back up but have no ideal of what size I should use. I have been searching on here and dsmtalk for around an hour and can't find a chart with vacuum line sizes or anyone who has even asked about them :confused: If any one could let me know what sizes I should be using for the bcs to the turbo teed off to the wastegate and from the bcs to the intake I would greatly appreciate it.

I am not sure what size it is exactly. You could always just remove the piece that you have on your car and bring it to the autoparts store.
I wish I could but the last owner unhooked the BCS and ran a line from the wastegate to the turbo. It looks like the nipple takes a 3/16" but I'm not sure.

I meant.... remove that last piece that is running from your turbo to your wastegate actuator (its the same size) and take it to the autoparts store. Understand?
Well that part confuses me because it doesn't look like its factory and it starts as a 1/8 or 3/16 and then went to a reducer up to 1/4 to a splice to another 1/4 then another reducer back to 1/8 or 3/16, so I kinda what to comfirm what the size is supposed to be.
