Years ago I got a set of pistons and cylinders that were suppose to be off a 2.2 motor that someone had put a big bore kit on. Last year when I’m getting ready to do a ring and valve job on my 2.2, 911T  I find that the cylinders are bored to 85mm and that the pistons are standard 84mm. 
      Upon disassembly of my engine I found that my pistons were just fine and so did not use these.
     The pistons are in very good used condition, a few abrasions but otherwise you can still see all the factory machining marks and I would not hesitate to use them with new rings. They are stock 84mm with casting numbers Mahle 84V48  C011+  the wrist pins are included. They should fit both the 2.2 and 2.4 Porsche 911 engines as they both have the 84mm bore, the 2.4 is just a longer stroke. Check the numbers to be sure.
