Bushing conrod small ends to accept different pins?

[IhmeJanneFIN]

Hi all.

Been thinking pistons for my boosted short stroke 750 project and came across that gsxr 1000 pistons are 73mm which seem to be forced by looking at pics. The diameter would fit on my current bore on my engine. Problem is that these pistons use a 16mm wristpin and my engine uses 19mm wrist pin. Height wise I would have to calculate compression and hope for the best if I am to fit these.

I have seen people fit bronze bushings on the small ends to fit the smaller wrist pins on some automotive applications and also some oem conrod seem to use some sort of bushing at the small end from the factory.

If I would be to fit such bushings to my conrods, any idea what material it should be? Obviously it is a machineshop job as the inner diameter has to be honed to correct dimensions.
