Hey guys

So i know I have to use the side port on the WG to hook up the vacuum line. The top hole on the WG is supposed to be vented if you are not using a boost controler, however my WG has two openings on top:

Do i leave the bigger top opening vented and cap the small one on the center?

 

You only use the top one if our using an electric boost controller if your using a manual bc you just put it in line with the air hose going from ur turbo to the Wastegate. As for the two holes on top? What make and model and was it brand new when u bought it?

 

Its an HKS knock off. I got new, but who knows...

 

the center hole should have some sort of set screw in it, used for adjusting opening pressure, normally that is...

 

Correct, there should be some sort of long set screw with the jamb nut to adjust when it opens.

 

unless it has a preset spring. My waste gate on the eclipse came with a 10 psi spring and a 15 psi spring.

However, that wastegate looks like the china knock offs. and they should have a set screw and a barb on top or a plug for electronic boost control.
