Wastegate actuator selection
Hey guys,
I'm trying to pick out a new wastegate actuator. I've got a BNR Stage 2, and it has approximately 12psi crack pressure on the actuator. This wastegate pressure is way higher that I can run right now. I am wanting to decrease the wastegate pressure back to stock, but I'm not sure what I should purchase. It would be a hundred bucks or so for something that may or may not fit or work with the setup. I am wanting to run stock wastegate pressures and have it controlled with the stock boost controller (S5 TII). This is for engine safety. Had I known better, I would have ran this configuration before I blew my engine.
What are the stock wastegate pressures for the S5?
Is there an actuator that would fit the BNR Stage 2? I think it has the compressor size of a GT2860 or something like that.
I have looked at possibly a Kunigawa, or the copycat Tridt, actuators that have different rod lengths and shapes and you can change the springs out. Thing is, I have seen mixed reviews on those, and they look like an ali-express quality item. I'm not sure if those would be able to last for the long haul, although I'd be open to suggestions

the stock actuator is about 6psi, if you can find one, you might try it?

How about this one?

Only issue I can see might be needing a longer rod extension because the one pictured looks an inch or two shorter than the one I've got

you might need some sort of bracket too, unless yours has one
