Building Rotary engines to many is a black art.  At Tweakit we've developed techniques that allow street and high power race engines to be put together that stay together.  We only use the best of factory Mazda and aftermarket parts that we've proven on the road and track  Whether you need a Stock Port, Mild Port, Extended Mild Port, Bridgeport, Peripheral Port, Turbo or Supercharged build we've got a package to that can win your class with the right driver behind the wheel. 

Dave Potter's Targa Tasmania Tweakit Sponsored Mazda RX3 ran our 13B Bridgeport Motor in 2007-2008 and won it's class both years, the motor is still together in another car.  In 2009 we built a 13B PP (Peripheral Port) engine to replace it, and again it won the class for 2009 at Targa. 

Three years of wins in a row means Dave took home the Gold Targa Trophy in '09 to top off his collection.
