Hey guys I've had a 06 Impreza 4WD Sports Wagon 1.5L for a while now and I have got bored of it even though its mainly for work, I needed to know what engines that anyone knows of that will fit into that chassis. It doesn't have to be a Subaru Engine, but I need something bigger and better but still Japanese and what mods will I have to do to make it a snug fit. Cheers Jordan
