Tee on line off of BOV. Used to face down, re-directed to run a new line going to the inlet of the MBC.


Line running from tee to MBC.


This shows the MBC mounted to BOV hose and the line going to wastegate re-routed to reach the MBC (this is the line that used to feed to the bottom of the Tee above). Note- some of these vehicles came with a harder "plastic" type of line which tends to crack easily. If this is the case, you will need to just replace the line with new 3/16" hose available at any auto parts store.

If you follow the hose from the BOV, you will see that it goes to a Tee. The "back" hose on the tee goes to the intake, the "bottom" one goes to the wastegate- this is the one you will be removing. You have to reach underneath and re-reoute this hose so that it will reach the MBC (or just replace it with new hose), kind of a pain but you will see what I am talking about when you get to it. This hose goes to the "outlet" of the MBC (see MBC install instructions) and then you need about 8" (if that) of 3/16" hose to run from the inlet of the MBC to the Tee. I just rolled the Tee and hoses so it faced up and towards the engine and routed the hose from there to the MBC. It was simple and you will be very impressed .. Also, before I installed the MBC, I opened the valve and blew through it while turning the screw back in *just* to the point where I couldn't easily blow through it anymore. That is a good starting point for "setting" the MBC, however the only way to set the MBC is by test driving it and increasing/decreasing it as necessary.
