i just bought a 93 twin turbo rx7 yesterday. the guy told me if i replaced all the vacuum lines that the problem would be fixed. the second turbo doesn't kick in until around 6200 or so. and when i get on it in 3rd-5th it makes this real crazy high pitched noise. im planing on getting a vacuum line kit and seeing what happens. any idea where i can get a good one? thanks
