The earlier year rb20's had "RB20" on the front of the engine, whereas the later didn't. I'm not sure exactly which year they changed though, maybe '92?
I had a bonnet sent to me a few weeks ago that was damaged to all buggery as well, they'd left it sitting on end and had obviously dropped it, bending up one of the corners to 90 degrees.
Have a look at page BF-62. You need to remove the small panel where the seat belt passes through the panel, as well as the top 14mm bolt that holds in the seat belt feed (both circled in red). Then you can pull away the bottom side panel and the reel is where the red box is drawn.
AFAIK Jasma (Japanese Automotive Sport Muffler Assoc) isn't a brand, its an association to state compliance to exhaust regulations.
JustJap has 3" cats for like $160, unless you're aiming for a lot out of the car i doubt you'd notice any difference.
Try Matt Spry at PITS, i heard a rumour he might have gotten hold of the software. If he can't then no one else in Qld can, you'd have to go to Sydney.

I've searched trying to find an answer to this question as well because i've got the same turbos, but from everything i've been able to find the general consensus is that the wheels are ceramic.
