I own a 2000 USDM Subaru Impreza L model. It had an ej22 motor in it, but i recently put an ej25 motor into it and turbocharged it. The motor came out of a 2002 Forester and the turbo came from a 2003 USDM WRX, TD04 Mitsu. The engine is sound and runs great, but i have yet to apply any RPM's to it because it is still not tuned. I am having trouble figuring out a way to tune it since it has an ej25 turbo motor in it with an ej22 ECU controlling it. If anyone has any suggestions as to what i can do it would be greatly appreciated.
