Hi! I just upgraded my s4 turbocharger to an s5, All looks great. Twin scroll removed and capped. Only the nipple sticking out of what looks to be the metal line on the turbo that runs to the wastegate. Do I plug that?
Thanx!

 

Are you talking about the nipple on the front housing of the turbo? because if you are....that needs to be hooked up to the wastegate!! If not....Your gunna be boosting off the scale!!

 

yes it is hooked to the wastegate, however there is a nipple inbetween that is not on the s4... I dont know what it goes to. Thus, should I cap it?

 

Stock, there should be a line running from the nipple on the WG to the nipple on the compressor housing. So, if we're thinking of the same little "L" shaped nipple, yeah, this should be connected to the WG.

 

I remember doing this last year, I read to cap it off from this site which i did, mine still boost stock boost I do not boost of the scale

 

Excellent thank you.

 

speaking of which.. i need one of those nipples. where would i find one? i already looked everywhere
