For this build I purchased CP Forged Pistons from RaceEngineering.com and forged connecting rods from kainjection.com.
Specifications:
Pistons:
Part# XTP-562P85R CP Forged PISTONS MAZDA/FORD 626/PROBE 85.0mm 8.5:1 V6 2.5L +RING (20mm Pin)Rods:
Mazda/Ford KL 2.5 V6 Forged connecting rods. (20mm pin)
Piston Ring Fitment
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. This it actually proved very handy vs using an actual piston as a push rod.
I used a cheap ring file to size the rings according to the guide that came with the CP Pistons.
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.
