This is just a thought and who knows it just might be helpful. I've search through a few thread regarding wastegates and such. Anyways I read a post about people buying replication of name brand wastegates off of ebay and swapping out the internals like the diaphragm and spring with name brand products. It seems really interesting and could potentially save alot money. I want to see how many people have done this and/or their thoughts about it.
