i was just in the same place as you a couple weeks ago. finally saved up money for the vortech s trim then i researched more and now i'm broke without the kit. you gotta get: fuel injectors, fuel pump, fuel pressure regulator, mass air flow conversion (for us 87' people), throttle body would be smart. after i thought about it for a while i decided just to save up for an H/C/I combo. it is a better way to start building a powerful stang rather than just get a blower on a stock engine. but whatever u do hopefully it works out good
