KA vs. Z24 Rods

Post by datzenmike »

Had some time today and, well... idle hands....

I noticed that the KA24E piston is held in with circlips and is a fully floating set up. I pulled the clips and tapped the wrist pin out. No press needed. The piston pin hole in the KA rod appears to have a copper/bronze? bushing in it that the pin rides in. There is an oil hole up through the top of the rod. The Z24 rods are press fit and may not have this oil hole in them. The KA and Z24 pins appear to be the same diameter. (different pt. numbers)

The Z24 rod on the right seems thicker and stronger than the KA rod. ???

Both bottoms appear the same, or close, except for the larger Z24 rod nuts.

15cc dish Z24 piston and 2.8cc KA24E piston. Pistons are pretty much identical with same pin height and diameter and will swap into the Z24. KA24E pistons in a Z24 block will raise the compression to 9.88 with the stock NAPS head. Open chamber L head... 11.77, closed ..12.66.
