good to see some other views. I used the exact same external wastegate as you shaun before, But i couldnt seem to find them anymore on ebay.

I like the build of that one in ebay and it looks to come with good gaskets etc....

I ran my wastegate external with no sreamer pipe going to atmosphere and mine seated fine everytime at idle. I used a 1 bar internal spring and for a while used no additional controller with it. It was a very stable boost pressure.
Gripo has a greddy electronic controller.
Will have to see where his wastegate outlet sits and go from there.

I want to fit an external wastegate to my evo at some point soon. Im just unsure on what manifold to go for.
