.020 over? .030?

uhm it really depends.. you might want to find pistons and rings to fit that bore before you go and bore it over. aluminum block= piston sleeves.

well, pistons can be made to fit any bore from what I have seen, how much can the stock sleeves be bored before issues abound.

You can go .5mm. Not sure beyond that though.

Most just bore it .5mm or .020 over. I would do that, then stroke it to a 2.2.

has anyone stroked it yet? doesnt the 2.2 use a different reluctor wheel and some other nonsense?
