About to swap SPI to Zetec
 
Ok...

I read as much as I could about the SPI to Zetec swap... So here it goes.

List of stuff I got:

01 Zetec 71K

01 Zetec Harness that goes from ECU to engine and fuel pump

01 ECU with Key

01 Passkey module - i thinks this is for the factory alarm or something

Left Motor Mount

TB to MAF tube

Anyone know if the power steering pump from spi will work?
Anyone know if the alternator from spi will work?
Exhaust manifold is different. Anyone know where to get a Header for an 01 SE zetec for less than 200?
I heard the AC compressor is different so I am gonna get one.

Anyone have any suggestions, any help would be greatly appreciated.

I am taking my time on this, there is no hurry but I would like to have it done within a month.

Thanks,
Joe

SPI to Zetec Swap Augmentation
 
You can use the same AC compressor; you just have to remove and rotate the clutch 90 degrees. However, I find it best to use a new hose assembly to the compressor.

You will need two keys from the old PCM, if you want to program the keys that fit your existing ignition yourself.

If you use your SPI transmission, you will have to have the SPI gear ratio programmed into the Zetec PCM.

You will also need the coolant hoses and the little pipe that mounts above the radiator.

A new power steering pump and line to the rack is required.

The Zetec also requires a different cat converter & flex pipe.

You will also need a new throttle cable and the positive battery cable to the starter, which goes on to the alternator on the Zetec.

You mentioned the main harness, but you also need the engine harness and the transmission harness. The engine harness may have come with the Zetec, but you will find that the transmission harness between a SPI & Zetec are different (i.e. crankshaft position sensor, O2 sensors, etc.).

The vacuum line to the power brakes is also different.
You will need the small vacuum lines that connect to the intake manifold.
Also the fuel line to rail hose assembly is different.

You will need a new alternator.

In additon to the passenger side motor mount, you also need the bracket that it bolts to.

That's all I can think of for now. I've done 3 of these and have parts in the garage for 2 more. Let me know if you run into any problems.[ffrocks]

I didn't do nothing to my computer for my zetec swap when I use my spi trany and it shifts fine and their part numbers are the same for eithr engine if you try to order a new one

Did you use the SPI ECU or did you change to the Zetec ECU?

Cant wait to get the car running. I put a 5K stereo in it right before it died. Also new exhaust from manifold back and new tires. Whole car was Dynamat for the sound system also. Then 2 weeks later it dies. I wonder if my bass had anything to do with the valve seat dropping. My car hit over 142 dbs on the meter.

you have to use the zetec computer cuz that controls the zetec motor. i researched it and the trans are the same and everyone told me no there not the same but if you try to order a new one for either engine it gives same part number sdame exact commponet. i used my spi trans and car runs 100% perfect shifts smooth just like it did before the swap. you have any questions on your swap pm me.

i used zetec ac compressor and lines but flipping it 180 degrees may work.
starters are the same
some ps pumps are same mine wasnt you need the whole harness from fuel pump forward, runs down passenger side to fender well into engine bay. halfway there it goes under passenger seat to shifter.
also need zetec trany harness that goes to o2 sensors an trans.
exhaust manifold and flex pipe
air intake tube but boxes are same
passenger motor mount and the black stand it mount to
someone told me the fuel line that goes from fire wall to engine is needed i got one but they looked the same
high pressure power steering line that runs across front of engine
heater core hoses (i just pluged the T and extended my hose with some heater hose from oriellys
youll need the throttle cable and cruise cable their both diff, cruise may work with mod to braket but throttle wont. its super easy to change it
grab extra bell housing bolts from donor car zetec uses more than spi.
Also some people say trans wont work but i researched them and part numbers are same so i took the risk and tried mine it works and shifts perfect so you shouldnt have any problems using yours just make sure you for sure change that trans harness the spi and zetec are 2 pins different in wiring so it could have all the wires in diff spots that harness also needs to be from about same year car cuz newer ones use diff power steering pumps and have diff connectors and more wires.

Thats all i can think of right now any other questions shoot me a message
i tried to pm you but mine wont work

just finished my engine swap and the car is running good. unforunately, I have check engine light on with code P1520. Any idea how to get rid of this code? thanks

btw. its 2001 focus SE with automatic transmission.

Intake Manifold Runner Control circuit fault , I have no clue what this is and looked for it in my Haines manual and didnt find anything.

I am starting my swap this week. Everything is finally all ready to go.
