I have an HKS waste gate, and i'm curious to know what the two nipples are for. i know one of them have to be for the + line from the turbo. But then what's the second one for? i have a Profec-B that i'm trying to set for 10 lbs. It keeps creeping eventhough the spring is set for 10 lbs.

 

What type of wastegate? Standard or Racing?

I have the Racing, and I think it's set up the same as the Standard.

The bottom line is for the pressure signal and the top line should go to the Profec B control box.

What does it do if you just leave the top line disconnected? It should be around 10 PSI... if not, you might have a leak in the lower hose or something...

right now i only have the top line hooked up. The bottom one i guess is the one that feeds to the side. it spikes pretty much. But now i remember and realize that i need to adjust the 4 switches on the back of the Profec - B. I'll try to tie into the line coming out of the compressor, which should go into the side feed nipple. the top feed nipple on the wastegate should go into my boost control solenoid.

I think it's just the standard wastegate. What are the diferences?
