Keep in mind, this write up was for camry owners. I forgot all about it until today but you should be able retro fit this to our cars using the same basic ideas. It was written by a guy who really knows his stuff. He is not only an mkiv supra owner but has a 450+ (to my knowledge) HP '94 camry....so that should say something right there about his abilities.
