Stage 3 Subaru Impreza WRX High Performance Tuningworx STi Turbo Conversion - $5800 inc GST & Fitting

The Stage 3 Tuningworx 2003 to 2007 Subaru Impreza WRX STi 'ball-bearing' turbo conversion is a complete performance upgrade solution for your WRX Impreza. The conversion takes your standard WRX output to a level higher than the STI Impreza. What that means is smooth tractable power with a much stronger mid-range powerband and vastly superior top end performance. The system will do no less than transform your WRX into an STI humbling performance sedan or wagon with 0-100kph times in the high 4 second region. In the package we include the following:

1) STI JDM IHI VF34 'Ball-Bearing' Turbocharger.

2) STI ECU remap with additional enhancements (up to 1.3 bar boost pressure at peak - up from 1 bar).

3) High grade 304 Stainless steel 2.61 inch exhaust system from turbo to exit incorporating high flow catalytic converter.

4) Aircraft grade fastners.

5) Turbo boost gauge (illuminated).

6) Cosworth panel air filter.

7) Fitted and tested including exclusive Tuningworx STi badges (Front grille and rear boot-lid).

The STi kit is supplied with before and after Dyno graphs with output on finished conversion approximately 170KW ATW (on 98 Octane) up from the standard cars 125KW ATW (45KW increase ATW). This along with similar gains in torque of approximtely 25% across the entire rev range.

If you want the best 'no-nonsense' bang for your buck WRX upgrade, this is it - as the team at STI originally specified for the STI Impreza version.

Note: If you have already applied the Stage 2 Tuningworx STi kit then the cost of the Stage 3 kit is reduced to $3800 inc GST & Fitting. The Stage 3 kit comes with a 12 month quality workmanship guarantee and is recommended for engines having travelled less than 120000klms and with timing belt changed at 5 years or 100000km.
