Wastegate spring mod

[GSEclipse620]

I am planning on turbo-charging my 95 legacy with the ej22e n/a motor. I will be using the turbo system off of a wrx. Since the n/a motor has such high compression I won't be able to run much boost untill I do a rebuild. I'm pretty sure the wrx wastegate is set for 12~ psi, much more than I want. DSM stock boost is 6-7 right? Would I be able to just swap out springs? Or evan just the whole wastegate from a dsm onto the wrx turbo?

if the WRX uses a mitsu style turbo, then you should be able to no problem..

I'm pretty sure that subaru uses IHI turbos. Are springs universal? Or are they different sizes(physical dimensions, not tension). That is a good pt about them being different companys so tranfering a complete actuator assembly is out of the question I would think. Does anyone know of a place that would sell replacement springs? Would I be able to get them at napa or a dealership? I'm guessing if I went that route I would have to special order from somewhere and come up with the exact tension and physical specs for the spring I want. How hard would something like that be to calculate?

Thats just a bad idea in general. The mitsu WG acutator isn't designed to be taken apart. I don't know how the IHI work. But if you mess it up you run the risk max boosting the turbo.

You will not be able to get a stock MHI actuator to boost 6-7 psi, this article however, will.
