Quick and easy updates for today:
Bled the brakes with SuperBlue. Pedal firmed up a tiny bit, but this was more just for peace of mind and b/c I do it to all my cars :-D.
Changed the oil. Note to others, apparently not all SR20s use the same oil filter. I grabbed one for a USDM one, but apparently the JDM motors (or at least mine) uses the oil filter from a 1.6/1.8L Miata, FC RX-7, or the 2.0L VQ Sentra (I think).
I swapped over to the catalytic converter and replaced an exhaust gasket for my state inspection, and then re-installed the test-pipe. I was really quite surprised how much the cat choked this car. It did, however, make the car a lot quieter, which I kinda miss... State inspection also needed an accordion boot on my rack to be replaced and recommended changing brake pads soon, I'll confirm this and give Carbotech a call.
Picked up a used JWT Popcharger for half the price of new. Intake is louder, which I don't really like, but I bet it's breathing a ton better and therefore should be faster and potentially more fuel efficient. It came with a foam intake installed that Jason got for free, but I've never really gotten warm fuzzies from foam intakes. Just a personal taste...
Overall, I'm still loving this car. 30+ mpg, fun to drive, good looking, the total package. Only things left I am interested in doing would be to open up the cat-back exhaust to 2.5" (yeah, it'll be louder, but I bet there's considerable power in it) and a cheap re-paint could be in its future after I take care of a little body repair.
