turbo fitting
i got an internal wastegate that is connected to a fitting coming out of the turbo.
if i connect the external wastegate to the vacuum manifold, can i leave the hole open on the turbo.

no, if you do not use the hole on the compressor outlet as your boost source you ned to plug it up air tight. If you leave it open you will have a boost leak. More then likely it is a 1/8 NPT port, so just get a 1/8 NPT plug with a little teflon sealant on the plug threads.

Re: turbo fitting (Bartman201)
np, but on second thought you might wanna measure the hole. I have a 1/8 NPT adapter here and the diameter is 5/16" for the outer threads. Yours looks like it might be slightly bigger. If you have a 1/8 NPT fitting (doesn't have to be a plug) and try to screw it into the hole. That will tell you if you have the correct thread pattern or not.

You might want to use that hole as the refrence point for the wastegate, using the manifold might cause overboosting or slow wastegate response.

Re: turbo fitting (White Smoke)
If you are only getting 2psi you have one of the problems below:
Major boost leak
broken actuator
bent actuator rod
malfunction flapper valve
Most likely it is the first one.
