mate you have 2 use the 3t as the gudgeon is 8mm further up the piston ,fly cut these the same as 2tg pistons and use 3t crank go 1mm oversize as going bigger will split the bores
Correct, except that gudgeon is 4mm upper in the 3t piston. 88mm for over bore is safe IMHO. Many peoples seem to use 89mm pistons with success. Worth mentioning is that I saw recently someone selling 2T with 90.5mm pistons. The engine was out of rally car.
