Fully built sr20det keeps overboosting

I would take the solenoid out of the equation and run the boost source from the turbo directly to bottom port on WG and leave top open like you had it. This should be minimum spring boost pressure.


Here's a good read.

Ok I read the em and for for air ports that are not being used do they need to be capped off

The air ports on the solenoid do not need to be capped. The extra port on the gate should be open to atmosphere.

Ok so all the air ports at the lower should be open and then I should leave open at the bottom except for the one I using and then the port top leave open dumb questions wouldn?t that mean all them would be open.

You?re bypassing the solenoid. No tubing should be running from it to the turbo or wastegate. Exactly as below?

Yes I going to test that tomorrow possibly but I asking if I hook my turbosmart boost solenoid should I cap the not used air ports or even without it hooked up wouldn’t air leak out of and bottom 2 ports that are not capped

Nothing should be run to it…

Stupid question so I had the bottom one connected like you show but I have port on top like the pic and then on top middle have that port open. Should I keep all air ports open on the wastegate or plug ones I not using?

Just leave them open for the test.

Can you post photos of your setup?
