With fishing village it is pretty good - you can carry over actions and only need to hit a torturer to carry through. With a regular torturer engine, you need a really high density of engine components to hit off a second chain of torturers, to make it worth more than just buying another torturer. Unless something like fishing village, haven, etc. is out, odds are just too low to hit the chain and I'd most often rather have another torturer. When I can reliably get engines hitting of outpost, I normally have some deck thinning and that typically means that torturer loses a lot of its strength as the opponent can often quickly just grab curses and chapel/steward/etc. them away.
