If you go external.. try the punishment racing 02. They have the full setup with wastegate for $570.
My new car has it and so far I like it. Only issue I've seen so far was the previous owner said he ordered the black color wastegate but now the color is heat cycled and looks off on the color now. I can take a picture. Tomorrow if you want.
