i have a 4G64 bare block and crank on the way, what size pistons and rods will i need? do i need to have it machined, or can i get it sleeved? also does this casting have a 6/7 bolt differences (i.e the oil fittings inside the block) like the 4G63? I have tried emailing the guys @ magnus motorsports to see if they can school me a little, but they havent gotten back to me yet. or does anybody know who i else i can contact with questions like this? thanks.
