Walker is correct, the cylinder will get quite thin. You woudl be better off Making either an iron or steel cylinder, and pressing on a aluminum heat sink to it, so you arent trying to share wall thickness between the original cylinder and sleeve. Rigidity is an issue, esp in a race motor. Pluys there is an issue in terms of the residual tension from the required interference fit asnd the thermal expansion differences between the iron and aluminum, they need alot to hold, and the thin wall section will make it prone to split.
