To be honest man, just judging by your posts and the things you are asking, you really need to spend some serious time reading and learning everything you can about how engines work, mustangs in general, how a s/c works, the differences, the suspension and how it will react to what you do to the engine etc. just EVERYTHING man, really, you owe it to yourself (and your wallet). If it was me, I would be reading EVERYTHING on this site and every other mustang forum you can find FIRST, and THEN ask questions. There is enough info on this forum to last you months and months without even having to ask a question I promise you that. It's an investment in time, but in the end if you read everything you can, it will save you (and again, your wallet) a headache.

thanks im just trying to figure out what all 2 get prior to a sc?

What to get prior? No use adding a cai and tune. A handheld tuner would come with the sc if buying a complete kit. You could always do exhaust or gears. I would personally just save as much money as possible and really consider all your options and if you want a sc for the ending cost?

Be sure to also budget in the means to control that new power whether it be suspension, brakes, or even professional driving lessons if you intend on tracking it.

well here is my situation im stationed in germany for about another year. I have yet to find a place to install s/c on American cars. Im just trying to get my car ready so when i get back to the states in a year i can drop a s/c on her. so like what brand of gears, control arms. things along those lines to have her ready to use a s/c when i get back!..thanks everyone for the help you have givin me so far!!!

I like the e-force it's 5-6psi so it sounds "safe." I bought up and lower control arms from AM front and rear along with Steeda front and rear sway bar. Plan to get the e-force installed at Powered by Ford in Orlando. And need better tiers I guess.
