im mainly a nissan guy but money is tight these days and nissan are expensive to build not to mention they are predictable i bought this car to get to and from work but i noticed this lil 2.0 with the zetec in it actually kicks like a civic with a vetec so i decided i got to build this thing cause no body is expecting to get dusted by a focus at least i never would of till now especially after seeing some of the 1/4 mile times i have been seeing. everyone keeps talking about the svt though but i notice the faster times are always zx3's with zetec and turbo so which is actually better the svt motor or the zx3? lookin to start building this thing asap definantly need a project car im dieing of boredum so any advise as to where to get started would be great glad to be a new member here

the svt motor is all around the better motor. pretty much a maxed n/a zetec motor. if i had to do it all again, i would have saved my money for boost. that would be my advice to u. the money ud spend to be on par with the svt motor, u couldve spent it on boost and been faster.

Welcome to FF , You have a good Focus to start with , boost will be your best option and in my opinion a Turbo is the only rought to go
You can do about 250HP to the wheels with a stock engine much more then that and your engine wont last long , good rods and pistons , throw in some ARP head and main studs and stock head and cams and 400 is then safe and easy to do
I have a great DIY kit if you go to the Focus-Power section here in FF there is a sticky on it
The first thing you need to do is figure out your goals for HP

the zx3's have the mtx-75 5 speed which is better geared for drag racing while the SVT's 6 sp id better geared for road racing.
Aside from that, the SVT has the same block just with oil squirters for the pistons (not really neccessary), great cams from factory with vct (better than some stg 3 cams for a regular zetec) and a good flowing head, slightly modified regular zetec head.
With a stock head and build bottom end, roushturbozx3 made 400 whp with a gt35r turbo on 93 oct. not to mention, jared also made considerable power on a fully built zetec (over 500 whp with head, cam and IM work).
The reasoning behind using the regular zetec is: they are cheaper to obtain (both the car and replacement engines), have better drag gearing out of the box, and once built will produce the same HP and TQ as a similarly built SVT. SVT engines and transmissions are much harder to find, clutches are much more expensive, and they are rare over all.
Tom, FSW, Top Speed are all companies that produce kits for the zetec and range from mild to wild depending on you budget.
