M3 S50 to S52 conversion

Hi Guys,

I am busy with a project at the moment and hope that you guys can assist, No one I spoke to previously could help.
Here goes: I have a S50 motor, I want to use the crank of the S52 and the conrods of the S50 in the motor. Which pistons do I use ? please advise...

To stroke it to 3.2L.
My question is why not use s52 con rods with pistons.
Unless the bore size is different, I dont think they are you might be stuck with s50 pistons.

Want to sell it to me the engine instead of doing all that work?
