Zetec Swap Write Up

Ok I'm gonna make one of these cause I can't seem to find one. If I seach I just find threads started by someone and all the do is say use the search function. Truth be told the tread doesn't exist.




I'm in the prosess of doing this so I'll post up as I go.

This is a 2002 auto SPI going to a 2002 auto zetec.




What you need if the cars are the same year.

For Zetec:

-Complete engine harness (goes back to fuel pump)
-Engine computer
-Exhaust manifold and flex pipe
-Alternator
-Coolant hoses
-fuel rail fuel line
-Intake tube
-Key reprogrammed (reflashed) required after install
-passengerside engine mount and bracket
-ATX harness
-power steering line and pump
-throttle cable and cruise control cable
-Positive and negative cables
-A/C compressor
-Flex plate




What you can reuse from your SPI:

-Driver side engine mount
-A/C lines
-Transmisson (auto trans is the same, but it is geared different)
-radiator
-axles if not switching from auto to five speed or vise versa.
-coolant tank
-MAF sensor
-air box













What I have now.

2.0 SPI SOHC



This is the donor car I'm taking the parts from.





2.0 Zetec.



Zetec wire harness


Zetec ecu that matches transmission


Zetec alternator


It don't hurt to change the timing belt while the engine is out. plus throttle body seal.


Zetec throttle body and throttle cable


Zetec power steering line.


Zetec engine mount and braket.


zetec water pipe.


Lower zetec water line.












Engine is in now for a test fit and to see what needs to be done with the coolant lines, and harness.

Hello, Ranger!

Please keep up with this thread; I have a Focus with a munched valve seat too, and am considering sticking a Zetec in it. I've been trying to figure out what needs replacing and if it's worth it.
Ironically, I bought my car new and looked hard to find the SOHC engine because it gets 1 mpg better mileage than the Zetec. Until the valve seat falls into the cylinder, anyway. I haven't driven it enough to check the mileage since then, though I was considering adjusting the valves on that cylinder to never open, and pulling the plug wire to see what kind of mileage I'd get on three cylinders...

Thanks for putting in the time and trouble to keep us informed on your project.

No problem. I myself have seen how aggravating it is to look all this up. I will keep updateing the first post as I go, feel free to discuss and add things to the thread. When it comes to price just do your research and don't be afraid to ask around your local yards. I got a hell of a deal on the zetec and parts cause I told them I was needing a engine swap and asked if they could give me a package deal. So far I'm only in the hole $500.

From this thread, you will also need:

Pass. side motor mount & black support bracket
ATX wiring harness (connectors are different for alternator & rear O2 sensor).
Throttle cable (different connector to TB).
Cruise control cable (different length).
Fuel inertia shut off switch (possibly)
Power steering line from pump to steering rack.

Let me know if you have any other questions.... had to do this to my 2000 wagon.

I know you'll need the axles from the Mtx. I don't know a lot about that swap i'll do some research and see what I can find.

Too bad my car is a manual. I don't believe the transmission will line up right so I'd have to replace that too.
