How much will have to be bored out and what size pistons will I have to buy to make the 4g64 a 2.5L engine?

Hmmm, might want to check and see how much cylinder wall you would have left, might be getting a little thin...??? Could cause overheating problems if your walls are too thin. Just my $.02 :roll:

You can only safely bore out the '64 0.020 over. I don't know how much extra displacement that would give you though.
