    When I removed my old engine from the bellhousing, the release bearing, a really weak spring, and a toothed ring popped right out. I was under the impression that the bearing and whatever the sping and ring are, were part of the slave cylinder assy? The bearing is fine, so I wonder what I should...

    My 5 speed 2005 ST has developed a concerning sound in the past few days. A couple really. But the most noticible is a sort of groaning/scraping noise that oscillates, and increases in frequency with speed (but sort of weirdly, with bumps/suspensions travel/turns). It kind of sounds like a shot...

    I've been doing research on multiple forums and testing out theories myself but I've come to the conclusion that ford designed the duratec platform to be dependable on power output and pretty much regulates it's power through restrictions throughout the system. From the tip of stock snorkel...

    03 Focus Duratec

    This was my very first car and still is my favorite car to drive. During high school I attempted to kill it many times but failed in all. Since then it has been used as a unique build in everytown I've lived in and still turns heads when I give it gas.

    I'm looking for an FSWerks header for a Duratec 2.3/2.5 and the flex to go with it. If you have a wideband too that would be cool. EDIT: I already purchased the items in question. No longer needed.

    OK, during my engine build for 2010 I needed to retain a stock Intake Manifold for class rules, so I ended up looking at alot of stock IM's used on various DURATEC engines and this is what I have learned. First off, all of the DURATEC Manifolds for FWD vehicles are black plastic. Only the...

    OK Fanatics, its time to start building my new engine for the 2010 racing season. [popcorn] Last year I qualified for an SCCA competition license, and ran in two highly modified classes with basically a stock D23. This was because I had swapped a D23 into my 05 ZX3 and added rear discs, so I...

    Hello all, I've recently kicked over 44,000 on my 07 ZX3 Focus, and realized I want to get more power from the thing. I've been reading the forums for a week straight, and see that I probably want to start with CAI, exhaust, and a tune as the first steps. My question is - what tune device...
