yes.. supposidly stock sleeves can handle 450-500hp .. it's the pistons / rods that will fail. so if you went with forged internals, & made sure the cylinder walls didn't sway via block guard, & used stronger head studs.. u should be able to pull 450-500hp out of a b18 bottom end without sleeving.
i'll make my attempt to prove this when spring rolls around!
