First, I know the donor vehicle is a 2002-2007 Impreza. I've been wondering that if I picked up a really cheap non-turbo Impreza with a bad engine as a donor, would it be possible to use a good engine from an '06 - '07 Legacy GT? Is there a difference between an '06 - '07 WRX and an '06 - '07 Legacy GT? Do we have any Subaru experts here?

I bought a Legacy GT new in '07. The engine and trans were great! Got rid of the car after 2 years because the front seats were TERRIBLE! My wife got a back ache within 30 minutes after we bought it. It took about a month for me to get one, but I did. I ended up having to replace the head rests (tilted too far forward) and disconnect the lumbar support mechanism. Those seats either had too much lumbar support or way too much lumbar support.
