I need some Subaru Guru help...

2.5 block with a GT30R external Tial wastgate. Im having a hard time getting the boost to be level. Its either 23+psi or 7psi. I think I may have a problem with the connections. How does th stock boost selenoid hook up to the Tial? As well is there a way to control the Tail itself?


Thanks all!

Assisting you requires much more specific questions. External wastegates come in two flavors, ones with boost nipple only to the actuator (a la internal), and ones with boost and vacuum. What are you using to regulate your wasgate solenoid? I'd enlist some professional help instead of trying to figure this out on the boards.

This one has boost and vacuum nipple.

Hook a vac line from the turbo comp nipple to the side port on the tial, that will keep you at wastegate boost for the time being..

I have never ran a tial wit the stock solinoid, but the side port is what you need to be hooked to a vac line, the top is used to keep the gate shut and is usually tied to the other port on the solinoid..
