Turbo 1 Vacuum Control 1985 ,2.2lt

Vacuum line diagram shows an "in-line" ORIFICE between the Wastegate Soleniod and the Wastegate Diafram on the Trubocharger. This Vacuum Orifice is missing on my system. As far as I can make out this "vcuum orifice restricts the flow of vaccum to the turbocharger. Without this orifice the turbocharger is getting too much vacuum and over boosting. Does anyone know where this part can be bought or what the specifications of the vacuum restriction are so the part could be substituted with another vacuum system part.

go to the junk yard and look in other cars i have a collection that i made using mig welding tips and they work great to big a hole the more boost creep i use a .15 for regular driving .18 for racing with boost about 13 psi but i have to make a little tune to my grainger valve just a little bit one other note it don't matter how close to the diaphram as long as you don't put it before the solenoid you will get boost spike like crazy
