I can answer these questions, at least I think....
did Supras come in naturally aspirated form?
Yes, I think they are 2JZ-GE?
did Supras in Japan come stock w/ 3S-GTE AND 2JZ-GTE?
No
Is the 3S-GTE 'better' or is the 2JZ-GTE 'better'?
depends on what you are looking for
Why is the 3S-GTE such a crazy swap when the 2JZ-GTE is so highly revered (or at least more so than the 3sgte)?
Because, from what I understand, the people who swap in the 3S-GTE are going for Top Speed, such as Top Secret. You don't need much torque for top speed cars as massive amounts of torque for launching are not needed. Plus there is always the respect thing ie. doing something nobody else does. I am sure there are other things, but somebody else will have to help you there.

Is it because that class only allows 4cylinder engines but the Supra body is just more aerodynamic than the MR2 (which, correct me if I'm wrong, is what the 3S-GTE originally came in)? Or does the 4 cylinder 3S-GTE actually have 'more potential'? </td></tr></table><span id='postcolor'> [B]IIRC there is a restriction on engine size and the 3S-GTE is the best size for that race
as always, please somebdoy correct me if I'm wrong <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
