Wastegate actuator

[nb07bcar]

Anyone know of a stock wastegate actuator that has a 10psi spring. I have a stock volvo turbo. and the actuator for the internal wastegate is at 5 psi and I would like to get a 10 psi. The turbo is made by missubiti td04-15G i think. anyone know of anything?

get a boost controller, you can take the boost up to 10 psi.

Dont have the money for a boost controller. What kind of controler are you talking about. The type that is just a valve that limits boost to the wastegate. If thats the type your talking about I had one on there and it couldn't controll it consistently. I would have boost going from 8 psi and then it would sometimes spike to 15 psi. So now i'm using the internal wastegate and the boost recirculating wastegate on the turbo. What the problem is that I build 5 psi real fast but to get to 10 psi it takes a long time because the internal wastegate is open. maybe if i buy another valve and hook it up to the wastegate and the recirculating gate I can control both with more persision.
