If you have the ZX2 head with VCT the STG3 Exh cam will not work the VCT heads take a special ECH cam , the best thing to do is switch over to a Focus head it is a direct replacement and flows the same as the ZX2 The best ported head money can buy is the Ford Racing head , there are some other on ebay by s Company that claim better flow but have never been able to produce any better HP/TQ then the Ford Facing head You dont have to go to a ported head if it isnt in the budget just a stock Focus head works and will make the same power as the ZX2 head Surface it and go to 10.0 compression and gain an easy 8-10+HP depending on mods , you will have to run 93 all the time and a good tune but well worth the cost You fuel pump should be fine but I would look for a set of 30lb Inj , the Focus SVT has 30lb and the Focus sites (focusfanatics.com) have them for sale all the time at a good deal You wont see 200HP at the wheels , maybe you were talking flywheel Tom

You cant use the Focus 65mm TB on the ZX2 intake manifold and I dont know of a 65mm for the ZX2 , you can make an adaptor for it You could change to a 2000 ZX3 intake and then use the 65mm Focus TB , the intake manifolds are the same as for where they bolt to the head it mostly depends on what fuel rail you have and you would have to madify the throttle linkage but not a big deal I like the comp stg3 cams and they are VERY streetable Tom

Jenvey mostly there is a few other i have worked on I am no expert with the ITB world Please everyone keep in ming that most of my work is with the ZX2 /ZX3 /SVT Focus which uses the stock intake manifolds It still comes down to the same thing how to make SAFE power with these engines and I can do that Tom

Sorry not up on all the ITB`s out there ,It would take a year on the dyno to test them all with all the diff combos It is fairly easy to get 155-165 with the stock ZX2-ZX3 intake manifold moderate built engine and 180`s with good ITB`s Tom

Oh come on ... everyone needs at least 300HP to the wheels LOL Everyone talkes in HP where they should be talking in TQ , coming off that corner to hit the straights with 280 Pound Ft of TQ would be very nice Tom

Yes I have tuned hundreds of the Duratec engines both the 2.0 and the 2.3 I own a Co. Called Focus-Power and do a lot of work with the Zetec because it came out in the Ford Focus in 2000 and thats when I started with the Zetec I have taken a Zetec engine to 723HP to the wheels in my daily driver , NA engine to over 220 with out ITB`s I also have a full machine shop , in house dynojet dyno , I tune with SCT and Diablosport for the stock ECU I work with all the Contour / ZX2 / ZX3 / SVT / Duratec engines and have tuned and built hundreds of them Best place to find out more about me is http://www.focusfanatics.com I would love to get me hands on a Caterham and turbo it to about 300HP as a daily driver Tom

To ID the Zetec is fairly ease The Contour and ZX2 will have a VCT Exh cam gear buldge on timing cover Exh side The ZX3 has to STD flat cam gears , flat timing cover The SVT has the VCT Gear on the Intake side , buldg on timing cover Intake side As for the questions about the Engine Management if you have the Ford ECU keep it it is by far the best Engine Management you can have and you have 2 options for tuning the SCT Pro Racer Package where you can tune the Ford ECU your self or Custom tuning from some one like me that can do your tuning 100% remote and has done more with the Zetec engine then any one Tom

If this is a track only car why are you running 2 o2 sensors , The rear o2 is for the CAT only and the front is nice to have for closed loop fueling (idle , cruise , part throttle ) but not used for Wide Open Throttle , you could take out the rear o2 altogether and just use the front or turn off the rear o2 with a tune Tom

In my opinion the Zetec engine has just as much potential as the Miata engine does maybe even more. To get 300HP to the wheels of the Zetec is very easy to do with a turbo as mine is making just over 700 to the wheels in my street Focus Zetec and I LOVE using the stock ECU in the Caterhams Stock Zetec bottom end with a good head , ITB and tune will net you in the 180 easy Tom
