Just got the hks wastegate and was wondering where does the two hoses go to. There's one on top and one on the side. I know one comes from the boost controller but, what about the other one and what does this hose do for the wastegate. Which one is for what???(top for boost controller?)
I tried a search, but nothing!
Thanks for your help!!!

 

on most aftermarket wastegates, the top nipple is for the boost controller and the side nipple is for a source right after the turbo (gives better response that way)

 

what about the little brass fitting that is in the side of the housing? could that be used? came supplied in my new housing that i bought from precision turbo

 

So, one is for the boost controller. The other is from the turbo??? before the intake or from the intake???
Thanks

 

after the intake, as close to the turbo as you can get it. you can even hook it to the manifold, it just isn't as accurate as if you hooked it up right after the turbo.

 

You would think it would be more accurate after the intercooler, because the intercooler may create a pressure drop?

 

From Maximum Boost, I read that placing the WG actuator line right on the turbo has slower response. Putting it right on the manifold after the throttle will yield faster response, and I believe that is due to a brief spike in pressure.
