Sorry if this is a stupid question or in the wrong topic area, but need quick help if possible. I was noticing the small vacuum hose line coming from the stock t25 wastegate/actuator was disconnected at the opposite end and I'm not sure where it supposed to plug into. Help please, i'm still a newbie on my sr20 and turbos so please forgive.............

 

It should connect to some vacuum line on the intake. I cant tell u exactly cause i have a ca not a sr.

Just look around there should be an empty connection somewhere. Not sure but i think it goes under the TB.

 

It could have been connected at a few different points. maybe a vacuum slot on the intake mani, or it could have come from a port on the intake before the TB. It may have also been connected to the stock sensor/restrictor for the wastegate line. you should be boosting crazy numbers and will blow your motor if you dont connect the wastegate.
