can anyone tell me how to tell the different between external wastegate and BOV,
on the external wastegate there are two line, where are they connect to? im not talking about oil lines but as i understand one of the line is a vacuum line what about the other line? where do i connect dat to?
Well, people HAVE actually used external gates as blow off valves - but they're much too expensive, clumsy and stiff to be any good. And a blow off valve wont take exhaust heat too well in general
