The Stage 3 Tuningworx 2002 to 2011 Subaru Impreza WRX STI T203/T204/T205 'twin scroll' turbo conversion is a complete performance upgrade solution for your STI Impreza. The conversion takes your standard STI output to a level higher than the awesome limited edition S203,S204 & R205 STI Imprezas. What that means is smooth tractable power available from low rpm punch through to a strong top end.
