Bore size. how safe

if im right in thinking, standard cossie bore is around 90.80mm, how far can you go on a 200 block.

Ive done 93mm on a pinto, but obviously that wasnt turbo'd etc.

so, how safe is 93mm ?

totally depends on boost pressure IMO,
I don't see any benifit of going for 93mm and 2.1 on a yb.

I dont intend to do it, ive just seen one for sale with it done and am trying to figure out why as its a freshly built engine ( dont about 1000 miles )
