This will be a mother of all bumps. Came here as friend of mine has Mazdaspeed engine and needed some specs and I can't remember those. Might be for sale if anyone is interested. Reading all this again made me miss my old MS-11. It was bought as a cheap track car and that what it was, how it lived and still solders on, LHD with BMW V8 and build crudely as drifter.
