Gosh, I am a similar boat. Recently purchased a smooth running Toyota 3FGC15 caught my tail obtaining filter, maintenance, technical info. Yes finding that stuff is tough, hopefully someone in this forum will be able to help you out.
In the mean time I have repository started at the address shown below, perhaps some things such as the filter PN#s, tune up info, etc will cross over to your 2 series machine. Buying OEM filters at the Toyota dealership will break the bank!
