Just wondering if anyone knows how easy it is to use a fwd zetec engine with a rwd auto box. What parts are needed, from what cars?

 

Cossworth or mustang T5 box is the way to go. They bolt on to zetec, but you will need custom flywheel for example from brutonpower. I didn't hear about an option of using some standard flywheel from other car. If anyone knows would be interesnitng to know.

 

Sorry, but it needs to be auto.

 

Sorry missed that one.

 

never seen it done so you would have to try and play about yourself mate, maybe start of with a zetec auto engine, flex plate and torque converter and i think a C3 autobox from something like a 1.6/2.0 sierra and also take the flex plate and torque converter from that and see how you get on

 

I have done a Zetec with Mk2 Escort auto box in my wee 100e. Was a doddle to do and the car runs and drives great. If you need to go automatic, as i did, then it is straight forward. I am using the escort box, torque converter, shifter and never yet had a problem. I originaly done my conversion using the 2.0L Silvertop, But changed it two weeks ago to an 1800 Blacktop.
My full conversion from 1600 Crossflow to Zetec automatic is on a different site, dont know if i'm allowed to say the site though.

You will need, Zetec engine, Mk2 Escort C3 auto box, torque converter and shifter, Zetec auto flywheel and auto tdc sensor, RS2000 propshaft fits perfectly as well. You will need a sierra 2.0L DOHC automatic starter motor. I used my cross flow starter with a 18mm spacer and it works great. You will need to get longer torque converter bolts and 3 spacers on each of the three bolts to go between the rear of the flywheel and the front of the torque converter. best thing i found, and still use, is 3 standard escort wheel nuts. PERFECT spacer size. You will need a vaccum outlet from the carb for the auto box as that changes your gears as and when they should. Then it's just the usual stuff for converting your car to take the Zetec engine.
E-Mail me for pics, parts needed and any more info you want.

Dont forget to put your conversion work and pics/details on here though

Thanks for that, most informative. Currently on hold due to financial reasons!
Hope it will happen one day soon.

 

gents, been following various threads trying to solve similar problem.
trying to mate zetec to auto later c3 with overdrive.

The mondeo flywheel bolted straight on and with the crank sensor the engine starts, however the T converter holes dont line up, not major problem.

However if I try using a mondeo Tc will the input shaft be the same as on a manual box which is about 23mm where as the c3 input shaft is about 19mm. has anyone solved this problem as I cant find a cog to fit over the c3 shaft to make up the difference ?

Or is there another solution ?????

 

Glad to hear you are getting back on with it.
To use the Mondeo/Focus automatic flywheel/flexplate on the zetec engine to mate with the C3 torque converter, you need to get the flywheel/flexplate redrilled to exactly the same 3 bolt patern for the C3 torque converter. The best way to do it is get a hold of a crossflow or pinto flywheel/flexplate, put, on top of the mondeo/focus flywheel/flexplate, so that the dished sides of each are touching, place a black impact 24mm socket into the centre hole of both flywheels/flexplates. clamp both together and drill through the 3 holes of the crossflow/pinto flywheel/flexplate. This will give you the identical patern on the mondeo/focus flywheel and you can then bolt the C3 torque converter to the flywheel/flexplate. You will notice a gap of approx 13mm between the flywheel/flexplate and the torque converter once the box is fitted to the engine. I got a 3 bolt spacer made from ally to take up the gap. I ran the zetec with C3 auto box for 2 years with no problems whatsoever.
The mondeo/focus flywheel/flexplate is a 4 bolter for the torque converter, C3 torque converter is a 3 bolter. The mondeo/focus torque converter will never fit a C3 box.
If you want pics of how i redrilled the flywheel/flexplate send me an email and i will send some.
Bit long winded explanation but, what you want to do is get the two flywheels, put them back to back, 24mm impact socket through the centre hole, tight fit so no errors, clamp together and drill through the 3 holes. bolt to engine........bob's your uncle, jeannie's your auntie.

my box is the A4LD unit which I'm told is the c3 with an overdrive as fitted to scorpio ultimas. 4 stud Tc but different location studs. can drill but worried I will loose some of the crank sensor lugs on back of mondeo flywheel
