Hi,
like many others, I always thought that the turbo was the same on all versions, or at least with minimal updates, but a Facebook post suggests that the size of the snails has changed over the years.
IA suggests this, but I don't trust it too much. Does anyone have direct experience of replacement and dismantling?
