really for a chrome, genuine, you know is gonna work, forge part,. 125 bucks is nothing. I really recommend in if you need a stronger WG. I tried the helper spring idea and stopped half way through thinking, "this is gonna look kind of crappy when i'm done."
I kept breaking helper springs. Not fun, although I will say having a wastegate that held the correct PSI was awesome.
I ended up using a 9000-style bracket (which utilizes a bolt-on actuator instead of the one-piece c900 t3 unit) with a brand new turbonetics 9psi WG actuator. Ran that for a little bit, then my turbo bit it.
From then on I've used an external wastegate and they are fantastic.
