I'm not too sure what kinda power is needed to run x.xx in the 1/4 but i figure anywhere in that range should make the car a little more fun so that was my shotgun guestimate for where i wanted to be

I have Cranes #224-0010,Fwerk's header,BSD,UDP's,steeda's sri,Denso's iriduim plugs & a Fwerk's tune & I can get over 35mpg blowing down the freeway. I do like the 0012's but this is my DD & I've had more than my share of cammed up cars. They're awesome over 45-5000rpm, but not really DD style. The crane cams really make a difference.

In previous applications ive worked with, its always (after some other work has been done) been beneficial to remove that, as it begins to provide a flow restriction. i also noticed the cossi and knockoff intake manifolds appear to delete this

You can't beat a dual runner manifold= two runners- the low end is longer & the top end is shorter. Look at the SVT's or Honda's/ Acura's. You can say the Cossie's are single plane manifolds, but you can't compare a dual length runner w/ a regular dual plane manifold. You only have air flowing thru it & the composite (plastic) manifold is smooth inside as it doesn't have to atomize the fuel droplets. Yeah, you can't beat the looks of a Cossie manifold, but for a DD, you really can't beat the 23 manifold. How many guys to you see running a single plane manifold on a SVT, let alone a different one? A few people said the next step for me is a Cossie manifold w/ the mods I already have. The only manifold I'd change out to is a escape manifold= it ditchs the imrc= aka tumble flaps, then I'd need another tune for the imrc delete.

Yeah I have my st with I/h/3"exhaust/ cossie IM tune. And it's a blast to drive I love it but in 2 weeks I'm finishing my turbo kit so no more n/a power :)

so basically what im thinking at this point, as far as engine wise:

-Throttlebody (factory is sticking closed, so may as well replace)
-CAI
-BSD

followed by:

Cams
Header

some form of exhaust..haven't found one that sounded good yet

When you add a header & cams get a tuner w/ the 02 senser & egr delete.
Get a Fwerk's stealth exhaust.

I'd tell you to get an MBRP exhaust, but good luck since they don't make them for the Focus anymore. I LOVE my MBRP and I've never heard anything bad from anyone else with MBRP.
