Yes, the 993 rods are narrower. Solution: new rods.
Then the crank "snout" -- where the pulley mounts -- is different. Solution: custom pulley or modify crankshaft (if you have someone qualified).
And now all your pistons are traveling up and down an extra millimeter each direction, so you need to watch your clearance to the cylinder heads and valves and to the crankcase webbing. Solutions: piston machining or new pistons, or head machining, or shim cylinders, or...

Adding stroke to the engine is not a simple bolt-in conversion.
