There are companies that do this, L.A. Sleeve comes to mind.
I doubt that they would do a HT engine though, but ya' never know.....
The stock cylinder will need to be machined to accept the cast iron liner with the liner having an overlapping lip on the top to enable the cylinder head to lock it into place.
Also, the cylinder ports will need to be machined in place before the liner is pressed in.
It is quite a daunting task to try to do in your garage!
I have had 4-stroke cylinders lined, and have worked on 2-stroke engines that were lined previously. It is a great alternative for older engines or antique engines when finding a good cylinder is impossible or cost prohibitive.
plinko: A chrome bore can easily outlast a cast iron bore, but a cast iron bore has the advantage of being re-sized to accommodate a larger piston for the sake of rebuild ability.
Even a chrome bore can be striped and re-plated. Though, once again, it is a matter of cost versus practicality. If a new cylinder can be had for cheaper that a re-plate, why do it?
Jack: I am by no means anywhere near an expert on proper cylinder alloy. I do know however that having a high nickle content would lead towards having a lubricity benefit. Not necessarily making it resist wear through toughness but rather through slickness. (is that a word?)
Have to agree with GearNut plinko: plinko: A chrome bore can easily outlast a cast iron bore
Why would you want to use two materials with differential expansion properties for the piston and cylinder.
Aluminium expands at twice the rate of cast iron, so with a cast iron bore you need larger piston to wall clearances and aluminium is more responsive to changes in heat variation, helping to maintain more consistant piston to bore tolerances.
