Some progress today. I guess "RTS" is officially not an option:
I left the front / top portions of the support in place because they hold the bumper. This gives me an excellent view of the space I have to work with, though, so I think I'll probably get the splitter sorted next - should help me understand exactly how much space I have to package everything and sort out some nice, smooth, laminar-flow-allowing curved ductwork.
And then the oil system.
And then start the goddamned thing already.
