My question is this will a 2007 Ford Focus, 2.0L Zetec engine work with my current PCM and 1998 escort zx2 car?

THe donor motor has no computer and no tranny.

I heard that the cam timing is different but would like it confirmed..

Thanks :wink:

I Focus Zetec won't even bolt into a ZX2. The block has different mounting points.

you could use a Focus Zetec short block.
Sorry but from what I have read the motor mounts bolt in different places on the Focus Zetec and the mounting points on the actual engine block are different. If they were the same everyone would be going after an SVT Focus engine to swap into their ZX2. I have seen pictures of a ZX2 with this swap and custom motor mounts were needed. I know they both are Zetec's but the block has differences that would make the swap unfeasible for just an engine replacement.

all zetec short blocks are the same. You can remove the Focus mounting points, and reinstall ZX2 mounting points.

I've done this on a spare ZX2 of mine, when I broke the crank. I bought a cheap Focus engine for $200

And also people want the oil squirters from the SVT short block too.

For a complete SVT engine install, then thier would be a lot more work required.

Yeah, the mounts aren't an integral part of the block. They are separate parts bolted onto the block. The lower blocks are different as well and so is the head since they don't have VCT. The only issue with the head is wiring up the cam sensor so that your injectors know when to fire.

2.0 DOHC Zetecs are all the same motor.
:!:

The 2.0 L Zetec shared its 84.8 mm (3.339 in) bore and 88 mm (3.465 in) stroke with its predecessor, the 2.0 L 2-valve CVH.

A high 10.2:1 compression ratio and larger valves contributed to the SVT version's much-higher output.

Applications:

* 1998-2003 Ford Escort ZX2, 130 hp (97 kW) and 127 ft·lbf (172 Nm)
* 1999-2000 Ford Escort ZX2 S/R, 143 hp (107 kW) and 146 ft·lbf (198 Nm)
* 2000 Ford Focus, 130 hp (97 kW) and 135 ft·lbf (183 Nm)
* 2002 SVT Focus, 170 hp (127 kW) and 145 ft·lbf (197 Nm)
* 1995-2000 Ford Contour
* 1995-2000 Mercury Mystique

I believe the 8 lb ft of torque difference was due to the weight...

Main article: Ford Zeta engine

The first Zetec-branded engine was the Zeta family, introduced for the 1992 model year powering the fifth generation of the European Ford Escort, the third generation Orion and the Mk.3 Fiesta. The engine was originally available in 1.6 and 1.8 litre versions with a 2.0 litre version appearing in 1993 in the all-new Mondeo. The "Zeta" name was dropped in favour of "Zetec" when Italian car maker Lancia threatened to sue Ford for trademark infringement.

Early versions of the engine had a problem with sticking valves - far more evident in the UK (and in cold climates), where a driving style with earlier gear changes is more common than on the Continent - unless a special Ford formulation of oil was used. After small changes in 1995 to fix this problem the engine was known as the Zetec-E. This engine received a plastic inlet manifold and EGR derived from the Mondeo.

The Zetec had another redesign in 1998. This version, the Zetec-R, had a two-piece crankcase which helped damp out noise and vibration, conventional tappets with shims rather than hydraulic ones, and longer connecting rods with a lower piston compression height. This engine was used in turbocharged form in the Focus RS and had 212 bhp (dubbed Duratec RS). It was also used in the Focus ST170 with a cylinder head modified by Cosworth with Variable Valve Timing on the inlet cam and had 170 bhp.

The Zetec can be identified by having a silver cam cover with DOHC16v on the bottom left, the Zetec-E has ZETEC16v on the bottom left and the Zetec-R has a black plastic cam cover.

Production of the Zeta family lasted from September 1991 through December 2004. Displacement ranged from 1.6 L to 2.0 L. It was replaced in most applications by the Mazda MZR-based Duratec 20, though some Zetec-SE engines were used as replacements on the lower end. Ford Power Products sells the Zeta in 1.8 L and 2.0 L versions as the MVH.

The 2.0L version in the North American Ford Contour was a closely related replacement to the previous 2.3L Ford HSC engine used in the Ford Tempo.

A 2.0 L Crate Zetec has a shipping weight of 370 lb (168 kg).

Why dont most know this? I have been looking so long for a swap and walked by so many Foci. :(

Did you use the stock SPI computer to run it? I know the Focus Zetecs had EGR instead of the VCT in the ZX2 which could make a swap easier if you wanted to keep the stock ECU for emissions testing reasons. If the swap can be done this way then that could save me a bunch of fab work if I ever decide to do the swap. Got pics?

Before you (99SseSPORT) start feeling that you could have done your swap easier with this information consider this. The type of swap you are doing uses the ZX2 wiring which can be easy if you have a 98+ SPI Escort. I have a 97 which uses the return line fuel system. In order for me to do the swap your way I would need to convert my fuel system physically and electrically to a 98+ system. You would also need to track down a ZX2 to pull the block mounting points and probably accessory drive setup off of to make it work.

Or use a fuel rail from a 95-97 contour/mystiques zetec and run a VCT delete.

I would also have to rig up EGR because if I have a CEL I won't pass inspection.

I pulled the harness and computer and a few things from a 2003 zx2 and the body harness from a 98 wagon and of course I had to get a new gas tank to use the fuel pump. I figure with the cost of the car and all the parts I may have 1000 dollars in the hole thing. Just finishing up the exhaust now

You need a ZX2 ECU. First you need to determine if your ZX2 in a 99 or 99.5.
 
#20 ·
If the MAF has 4 wires its a 99, if it has 6 wires its a 99.5.
If it has 4 wires then it needs a 98 or 99 ECU, if it had 6 wires then it needs a 99.5-03 ECU.

you just need to make sure it's a stick or automatic ECU. other than that any 98-early 99 will work.
