Hello,

I have been looking into do an interesting modification to my H23A1 Prelude motor. I have found that it is a simple process to drop H22 pistons on the H23 rods and put them in the 23 block and up the CR to about 11:1. My question is about the rods. I have just aquired a set of H22A4 pistons with the floating wrist pin. I will need to attach these to my H23 rods which are originally hydralically pressed on. I have been told that I will need to "re-bush" the small end of the rod in order to accept the floating wrist pin. I was wondering if anyone on here knows exactly what I need to do to the H23 rods to accept the the floating wrist pin on the H22 pistons?

Any help would be apprciated.

Thanks,
Jason

 

You need to take them to a machine shop.
