I think i may soon be needing a new clutch, anyone tell me how long an operation like this takes and maybe what clutch to put in? my99 ppp fairly standard power.

 

If you are good with the spanners you can do it in about 3 or 4 hours,if you are not it may take a day or more. On a ramp it's easy but there is a hidden bolt to
release the clutch fork. If running near standard power
I would fit a gen Subaru
clutch. Non gen don't last as long, uprated like Exedy etc will take more abuse but drivability issues like judder etc are annoying.
