i wouldnt be needing to do this if there would actually be those upgrades you mentioned ,shocker2k, for the focus spi. theres only so much i can get out of it. so i gotta think outside the box to do it right, and so far thats all i have. theres no stronger internals that ive seen for the spi, no turbos, or superchargers, i could go with nos but theres no point wihtout stronger internals, no pulley kits, or any good computer upgrades for the spi, no headers, and i think you get my point. all ive seen is just rims body kits and crap for looks. honestly im getting tired of not finding anything to make it go faster. i already guted it out, no rear seats or spare or paasenger seat. its not my daily driver thats why. so correct me if im wrong but i think thats as much as ill get out of my beloved spi. hit me back
