For this build I purchased CP (carrillo) Forged Pistons from Race Engineering

Part# XTP-562P85R

CP Forged PISTONS MAZDA/FORD 626/PROBE 85.0mm 8.5:1 V6 2.5L +RING (20mm Pin) 

I mated the pistons with KAi Mazda/Ford KL 2.5 V6 Forged connecting rods.

Prior to the installation of the pistons I had been tinkering with a 3d printer for the first time ever. “tinkering” as I was using tinkercard software to make things and print them, the first thing I made was a push rod for sizing the piston rings when filing them to spec. While a little unnecessary it actually proved very handy vs using an expensive piston.

The next thing I made as guide rods to aid when installing the pistons for assembly, they were printed in PLA and I was impressed with the 3dprinted threads that actually were a perfect fit.
