I need to know if this is true...I was told that the threaded hole on the compressor, of the turbonetics turbo, is to be plugged if you are using an intercooler. Because if you didn't have an intercooler you would use this for a vaccum source for the wastegate, instead of one from the intake manifold... If someone could verify this, and tell me how they plugged it that would be great....

 

buy a 1/4" brass plug at home depot.

 

if i understood what you wrote correctly, then what you were told was not true. this threaded hole is used for a brass nipple with a vacuum line that will connect to another brass fitting on the side of your wastegate, with or without an intercooler.
