i have a 93 SC 5 speed that is in good condition (minus the things i am working on) i will have 2000 gs pretty soon to spend on my car. i want to run 14s. how about jet hot coated headers hi flow downpipes and cats, and a catback exhaust all from supercoupeperformance.com and then a 5 % overdrive pulley. and then when i get more money i will upgrade to 38# injectors ad a 190lph fuel pump, but would the exhaust 5 % plus a k&n and air scilencer removed get me into high 14s? also im confused on how to do the air scilencer is it the black thing that is stuffed into the air box?? thanks.
