It's been quite a while since I've done any updates.
Recently I finally got around to installing my rear wheel skirts, and also blocked the upper grille for the winter, and switched over to a warm air intake:
I also had to replace the head after a timing belt break (the head was found to be cracked over the #1 cylinder between the exhaust port and coolant lines). After I got it back, I changed the transmission fluid to Royal Purple, and indexed the spark plugs. It ran smoother after indexing the plugs, but I didn't see any other noticeable effects.
