Wiht the Subaru engine bays its more about hiding and making it look nice. Most stuff can be tucked though. I am doing it right now in my Legacy. YOu have to remove all of the front body panels... ie.... hood, front bumper, both fenders, grill, headlights. It takes alot of ingenuity and patience. I am taking my time. I figure I could do it in a weekend, but i want it done right. SO I figure good couple weeks working on it alittle bit at a time will net me an awesome result.
