I just wanted to let some fellow rx7 owners know that I work for Subaru and they use ast's on the baja turbo which is mad out of alluminum the wrx has one, and so does the 2.5 gt turbo. All of these have four inlet outlets instead of our three the other one on the subies goes to the turbo. I might see if I can get one of the bajas and see if I can put it on my car.
