Was wondering if in SR20 Turbo is the boost pressure adjustable via the wastegate actuator. If so how?
Cheers

You can lengthen/shorten the wastegate actuator arm... but that's a little difficult... Alternately, you could install a bleed valve or boost controller.... (zei can help you with this ;))

you can also get HKS actuators to fit a variety of turbos. They are around 200-250 mark.

I dont know if you can get them on with out having to pull of the turbo, but if you can it would be a much more sound way o getting more boost.

i think they set it to around a solid 12psi.

its a more reliable way of getting more boost, but then - if you want it - you dont have a way of getting two boost settings unless you go higher than the wastegate is set at. eg wastegate 12psi, high boost at 15 - via a bleede valve or some sort of boost controller.

You will have to make the wastegate rod adjustable by modifying it suitably so when you turn it in the direction of the thread it shortens and the other way lengthens, turning the boost up and down respectively, not too what it needs exactly to do this though.
