I bought a manual boost controller recently, but I don't know where to install it. The instuctions say to "tee" into the existing signal line between blow off valve (I have a Apexi BOV, if that matters at all) and intake manifold. And it shows a connection from the MBC to the waste gate actuator with a vaccum hose(this part confuses me because I thought my s4 had a internal waste gate. Can I please get some help from some fellow RX7 guys please. I don't want to mess anythig up. If someone could post a pic and highlight where I need to connect the MBC that would be great.

Thanks

 

*sigh* google image search failed me...

you just tee off between the waste gate actuator and the nipple on the end of the turbo cold side. it doesn't have anything to do with the blow off valve.

 

there is a vacuum line RIGHT on the turbo that goes from the outlet of the turbo to the WG actuator. The boost controller would go inbetween them. Obviously you'llneed more vacuum line but as long as it is in the line between them and you don't make the lines really really long that's where it goes.

Don't put it in before you get a better fuel pump and those injectors put in.
