Mazda SKYACTIV-G PY-VPTS Turbocharged Engine Assembly

Complete 2.5T gasoline engine assembly for compatible Mazda SKYACTIV-G installations. The PY-series turbo unit uses an unusually long 100 mm stroke with a relatively low compression ratio for its family. It must not be substituted for a naturally aspirated PY engine solely because displacement matches.
