there used to me a site called monstermotorsports.com and they had the onster miata kits as well as a mega monster miata which was a supercharged 302 with all the goodies.. supposidly the only car faster that it from 0-100-0 was the 427 shelby cobra.. this was several years ago when i had my miata. I believe the conversion was over 20k for the mega monter. I will definatly build one as a project oneday
