Serge was referring to 2mm longer stroke that would give 3.4 vs 3.3 liter assuming stock bore.

I have a 993 crank in my 930 engine but it was done by previous owner. I'm not sure about the dia of connecting rod since my engine has Carrillo rods which I don't have specs (sizing). You will have to use a different crank pulley (993 or aftermarket) since it's nose is much shorter than a 930 crank. When I bought my car it had a modified crank pulley which is a combination of a 930 and 993 pulleys (inner portion of 993 welded to outer portion of 930 pulley). I dished this modified pulley and bought Rothsports aluminum 993 crank pulley. I had to try different size (length) fan belts until one fits properly.
