How can I tell which version Zetec I have?

[G2sound]

My 2003 S1 has a Zetec engine, but is there any way to tell which version of the Zetec I have (ie. ZX1, ZX2 or ZX3)?

[11Budlite]

ZX1: '95-'97 - Hydraulic lifters, aluminum valve cover, water pump pulley centered over crank pulley.

 

ZX2: '98-99 - Mechanical lifters, aluminum valve cover, VCT cam solenoid in front of #1 spark plug wire, water pump pulley offset to the exhaust side of the crank pulley.

 

ZX3: '00-'04 - Mechanical lifters, plastic valve cover, no VCT cam solenoid, water pump pulley offset to the exhaust side of the crank pulley.

 

The dates are approximate. Here's some photos. Sorry, they're the only ones I have at work.

 

Top to bottom, ZX1, ZX2, ZX3. Hope this helps.

Looks like I have an ZX3 motor. I found the VIN Birkin 2061 /03...found it hidden under a water line.

 

Still curious about the Emerald ECU and how user friendly it might be.

 

Spark plugs?

 

Thanks for the help

For the Emerald System:

Engine Management .

By Dave Walker.

Haynes Publishing ISBN 1 85960 835 3

 

D Walker is the man behind the Emerald stand alone ECU.

His book explains engine management and includes a software CD for the Emerald.

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:

 

Just curious, any experience w/tuning Duratec engines and, if so, do you have a preference between them and Zetec?

 

Also, why so much experience w/Zetecs?

 

Thx,

Mike

[1turbofocus]

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

723 hp, LOL! I am adding you to my Rolodex:).

[Jackal]

723 hp, LOL! I am adding you to my Rolodex:).

 

+1 one for that.

[S1Steve]

723 hp, LOL! I am adding you to my Rolodex:).

Mike,

I firmly believe that would make YOU the king at track events ........

[Kitcat]

I thot I was the King already:)! And with that much hp, I'd never survive my 1st track day. Also mite be a little hard on the tranny etc., etc. I'd settle for what Croc and Karl have at the rear wheels (250 hp???).

[1turbofocus]

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

Go ahead Mike do it and ... SNAP!!!! That would be the sound of your rear diff support being torn from the chassis. And I and my little 150 ftlbs of torq, driving on by.:seeya::auto:

[S1Steve]

Tom,

Here's the 50 cent question. Do know anything about the Web-Con TB and

 

ECU setup on a Zetec. 146 hp now, I be happy with an extra 50 or 60.....

Thanks , Steve

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 - What ITB's do you have experience with?

[1turbofocus]

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

[hoefi]

Tom, what level of power will the ZX2 stock intake manifold support?

 

Can a stage 3 Comp Cam and a 65mm single throttle body work with the stock manifold and head?

 

TIA.

[rzempel]

I have Crower stage 3 cams and a 65mm throttle body with stock manifold. The manifold needed to be modified a bit for the 65--I filled in the O ring recess on the top of the manifold and opened up the hole so that it matches the throttle body. With 10:1 pistons, and the above setup, I get 174 hp at the wheels.
