I have 5 nice used S52 pistons and pins, that will make a good set of 4 for your M47 crank build. They will NOT work with an M42 crankshaft engine. They COULD also work with an M44 crankshaft engine IF you plan to turbo, but might require taking a few thousandths off the deck, and I did not do the math to determine compression ratio. I can double check my M44 piston to see how much, if any, these would need to have taken off.
I also have a full set of 6 135mm M3 S52 rods. They appear to be in excellent condition. Wrist pins fit nice and tight. I think the big ends are the same as my M44, but will gladly verify.
Pistons: $75 plus shipping
Rods $100 plus shipping
