I have a bov with 2 nipples on it. I want to know where shoild i t the vacuum lines for both nipplie. I thing the bottom one is from a source after the tb but not sure about the top one. Any input is appreciated, my turbo is almost complete, just minor ends to tie up.

 

bov? do you mean wastegate. i don't completely understand you

 

What kind of bov is it? I have a greddy type s and I know the top line goes to a standard source, I just hooked it up to my intake manifold. I don't think the bottom one is completely necessary but bump for other peoples input on that...

 

Yeah its a greddy type s, so only the top one is necessary?

 

yea i just hooked mine up to the top one. works fine and sounds great.
