i have a big problem... i am trying to install a mbc on my aftermarket turbo cuz the boost keeps spiking and cutting out... but i dont think the turbo has a vaccum line thing or hole coming from the compressor housing / turbo..... what am i supposed to do? i am freaking out guys!!!!

 

First calm yourself a little bit. Were there no instructions with the MBC? And you might think about replacing (I'm guessing here) the stock BOV as well. replacing the BOV may stabalize the boost pressures quite a bit.

 

yeah there are instructions... i knw where to put the mbc... in between the wastegate actuator and the comressor housing.... but there is no place to put it onto the compressor housing... i will replace the stock bov.... but right now i was actually planning on setting the boost to around 10psi.. so there should be no problems with that yet... i am really trippin about the prblem with no vaccum line hole in the compressor husing... uness there is someway to bypass that... it is internally gated.

 

Is there a line coming off the wastegate actuator? Where does that line go? It SHOULD come right off the waste gate and go right back into the turbo.

 

the line doesn't do that it just came with the actuator and nothing else.. if ya know what i mean. it looks like there is no hole TO/FROM the compressor housing at all for vaccum lines... so i just took the line from the actuator and hooked it up to the wastgate solenoid valve... cuz it didn't have a line running to the compressor housing... i figured that would do the trick but it doesn't.... i really am confused... on the stock turbo there is the T of lines from actuator to compressor housing and to solenoid valve... but i dont have the compressor housin hookup so it is just running to the solenoid valve. when i noticed this i was like WTF?

 

oh, i dunno if i mentioned but it is an aftermarket 16g turbo.... i have looked at quite a few turbos like these and they got the same problem as mine...

 

is the 16g internal or external wastegated?
