That's a standard 2.0 flywheel as fitted to the 2.0 Zetec Mondeo 2.0 Zetec focus and the 2.0 focus Rs.

It's a big chunk of iron at ~10kg. And takes a 240mm clutch

It will bolt on to the st170 engine as it's just a tuned Zetec but the Mt75 clutch won't work with the getrag box and visa versa.

There is no standard ford Smf for an st170.

There is an aftermarket one but sit down before looking at the price. Especially the updated one but it is a very nice bit of kit. In fact it's a shame to fit it it looks so good.

And you may be able to make somthing work with the above Smf but you will need to space the clutch bearing to meet the shallower flywheel.

And then there is the clutch plate from a Vauxhall.
