I'm Automotive Engineering student from Finland, and I'm developing four-cylinder BMW M10 2.0 '77 turbo engine as my engineering/diploma work.
Major principles in engine development are very good engine breathing and a sophisticated electronic engine management, and my goal is to get around 500hp from it.
