I have the SBR manifold with the external wastegate flange capped on my car right now. i'm looking into finally getting the external wastegate and was wondering what all i would have to do with all the internal wastegate parts and porting and all of that to make it work. i've tried to do my research on the subject but have just found the dump tubes with the stock 02 housings. thanks for any help.
