Proper installation of a MBC

16g Spoolin TSi · 03-11-2004, 09:14 AM

I've heard a few ways of hooking up a MBC which is correct? Currently mine is connected to the lower J-Pipe for a positive supply. I've heard u should connect it to the intake manifold for positive pressure.... which is correct or better for tuning?

Well a 2G doesn't normally have a J-pipe which is why you "T" into the line the goes from the IM to the BOV.

T there at the BOV route the line from the BCS directly to the j-pipe, so the MBC would have a line off the WG- IM/BOV- and BCS?

You would remove the BCS completely from the equation.

You would "T" the BOV line, run that to the MBC and run the other line off the MBC to the WG.

I don't think either is better way, they both accomplish the same thing.

my source is 'tee'd' of the BOV line.

Could you read this question out loud to yourself, and see if you still need to ask it?
