Some people with tuned Fabia vRSs have solid flywheels in, as the
original DMF and clutch is considered OK with a mild remap, but not if
you're pushing nearly 260BHP (or rather the torque needed to generate
that power froma diesel).

Apparently there's a little more vibration, and a bit of chatter from
the gearbox at idle.

OTOH a colleague had his 306 HDI converted and said it was no worse, but
then again, his DMF may have been on the way out.

Whatever, if it was mine, I'd replace the DMF, either with a solid or a
new OE DMF. It's too much of a pain dropping gearboxes :-)

Regarding the clutch life, it varies according to how it's been driven,
but I'd expect about 80k as a reasonable yardstick.

I have come to the conclusion that on many vehicles it can be quicker and
easier to lift the engine rather than remove the gearbox (I don't know
about the OP model) or in many cases just slide the engine to one side while
changing the clutch (I changed a fiesta 1.25 clutch like that the other day,
total job less than two hours and preferable to messing about with drive
shafts, suspension, gear linkages etc.
