I didnt know that. Very handy peice of information. Thank you!
Can I clarify then, as I have a stock MY00 GC8 WRX with yellow injectors, that I can upgrade the TD04 to a VF34, replace the WRX
ECU to STI Ver 5/6
ECU (direct plug in?), and it will run safe like that?
Will any
ECU plug wires need swapping over?
