I rebore my engine in1362 with new piston from minisport.

does someone have an idea of the cr I will have with these pistons and a 21.4 cc cylinder head?

regards

You will need to physically "Volumetriclly measure" it all to know for sure

these pistons are hypatec:

I have nothing to measure. the only thing I know is:

dish: 8cc
cylinder head gasket: 2.8cc
piston: 73.00mm
cylinder head volume: 21.4cc

I suppose other persons have the same spec. I send an email to andrew, but no answer...

as said,,, to do the job properly you will need to have someone volumetrically measure it all ,,, anyone who suggests otherwise is only guessing, simple as that

& burette is what`s needed & also someone who is used to using one doing CC measurements on engines,,, "SOME" engine reco shops have them,,, what`s quite surprising is that "ALL" engine reco places don`t.

& the head gasket will more than likely end up as 3.5cc volume

Hi mate,

have you thought about using these pistons? You pay a little more, but you get a much better piston and ring set
