While sitting here just getting paid to surf the net, I came across this site. Granted he's an MR2 guy but he has some good info on the 3SGTE. This is a link to a bunch of Toyota Documents. http://www.lovehorsepower.com/ToyotaPDFs/toyota_pdfs.htm Another interesting set of documents.. http://www.lovehorsepower.com/MR2_Docs/toyota_technical_documents.htm
I found this yesterday, on my hunt for 3sge info, its a early press release of the 3sge back in 1984, it has some intresting comparsions to the 2selu http://www.3sgte.com/page_18.htm
