Is it possible to change a T-5 from cable clutch to hydrulic clutch? if so, how?

Would help if you specified what car!

X series, there are conversion kits.

EF/EL:

Yes it is possible, but not cheaply.

Considering the cable setup is 'pull' and hydraulic is push.

You'll have to modify the bell housing and clutch fork, as in welding fabricating or even replacing.
Then theres the clutch pedal, (less work) but its all R&D home made mods are required.

There is no quick 2hour slap on install to do so.

Don't spose you could shed some light on where I might find a conversion kit for an xf? I'm putting a tremec 5 spd from an au into my xf and have been told the au's had hydraulic clutches so I'll need to convert the xf to suit it.
