need a picture of the routing on the vaccume lines from the wastegate/j-pipe to the stock boost solenoid for 03 evo 8

 

vacuum lines

 

I have been searching everywhere and I haven't came across an answer yet, so I apologize for the thread dig, but does that diagram show the OEM boost solenoid top vacuum line go to the intake tube before the turbo but after the mas? If so is that where is must go? I have an Injen tube and the Positive Crankcase ventilation line from the top of the valve cover is going to the only port on my intake tube.

 

yes the diagram shows the OEM boost solenoid top vacuum line go to the intake tube. My advice is get an oil catch can with an air filter and run the crankcase vent into that and this way you will free up the port on the intake tube + you will have a cleaner intake and turbo with the catch can catching oil instead of flushing it back into the intake.

 

The side of the OEM boost solenoid that normally goes back to the intake tube can just VTA, it won't cause problems. Or you can just cap it off.
