whoops..... ;D ;D ;D ;D

has anyone ever thought of using an egr valve for an external wastegate? i mean, like of a chev or something, im not sure how exactly they open up but im sure it could be easily modified to work, and would be a lot more compact and already has a flange built on it.... just a thought
