Check out
www.mr2.com and
www.toyturbo.com as there is quite a bit of info on both sites. Also might wanna check out MR2 Forum at:
www.board.mr2faq.com although some of the people can kinda get snippy at times. I don't personally know of anyone who's done the conversion, but I believe the n/a car has just a non turbo version of the 3S-GTE, but I could be wrong. Good luck :flash:
