legacy engine
 

Hi i am new on here and just looking for some good advise! I have a 2001 2.5 gx legacy and the engine is pretty much dead, and i am wanting to swap the engine for a turbo'd one and i was wondering which engine would fit best and give best performance. I was thinking along the lines of a b4 rsk or would an impreza engine fit in a legacy????

And does anyone know some good contacts for finding engines?

Thanks
