Ok, since I plan on keeping this car for a while (no V6 manual option in 2007 and maybe none until the $30,000 mythological SVT Fusion makes itself known), I would like to know your thoughts on the most economical way to reach 180-200hp with the 2.3. My thoughts are: CAI (do any exist yet?) and a custome tune, followed by a nice header and....then what???? With a quality CAI, header, and tune you can probably expect a good 20 hp gain - maybe more? There are a lot of 2.3 Focus performance parts out there, but what works well with this car? I'm sure an intake cam is out of the question, but would a performance exhaust cam be of any benefit? Turbos and SC variants are out of the question...I want to do this for less than $1500 if possible.
