By "universal" do you mean an adjustable wastegate actuator? These I found to be quite pricey. So.... I used a 6 PSI actuator off my old T3/T4 because I could not find an OEM for the TD05HR that went that low, and since at the time being I am still running low boost. this was the best option. I simply made a bracket for it to attach it to the turbo to operate the dump valve since it wasnt technically made to fit the TD05. As long as you make the bracket properly, you will not damage anything. That actuator simply needs to open the dump flapper consistently over time. I used about a dollars worth of some beefy strapping and made my bracket in a vice. Took about 10 minutes.

What you are looking at in the links are more or less OEM actuators. I do not believe you can crack them open as they have a diaphragm you will more then likely destroy getting it open. You also degrade the reliability and accuracy of that actuator is you hack it open. If you are wanting to pursue this route, your best bet is to get a bonified adjustable wastegate actuator and get the exact spring you want. They make them to fit the TD05 with no modification. I simply went the route I went to save a buck and new it would work just fine.

Okay, So I think I'm going to grab one of those t3/t4 actuators and fab up a bracket. I just ordered BOV/IC/IC Piping yesterday and actuator today.
I should be installing it all sometime after finals week.

I'm just looking for a shop currently in my area that can do my BOV flange and wideband bung. Kinda easy/small, but I really don't want a leaky BOV.

You could always use a BOV adapter. Thats what I use and it seems to work just fine. Basically, you are adding one more silicone coupling to your install. Similar to this, but I have 2.5"
