Stevelawrie Posted April 14, 2017 Share Posted April 14, 2017 Hi guys wonder if anyone can shed some light on my problem. I just rebuilt my uk 300 using a wrx doner car which was running perfect with no issues. Since I've changed everything over including Ecu but now my car has no turbo boost at all and it comes up with a swirl flap fault code. I know the car is a sti so are there differences in the wiring loom between the wrx and sti? Both cars are 2002 models and both uk models Quote Link to comment Share on other sites More sharing options...
Sandals Posted April 14, 2017 Share Posted April 14, 2017 The turbo and injectors are different on the STI so if you're using the WRX ECU it will need to be remapped... Not sure what that error code means though Quote Link to comment Share on other sites More sharing options...
