If you can afford a Ferrari, you let someone else worry about that!..............
How would you rebuild?
^^^^^This
Have removable ‘cylinder’ sleeves
What is the percentage of high-end auto engines that are ever rebuilt?
I don't think you would. None of the existing machinery to bore, hone and resize would work on oval cylinders, pistons and rings.
I'm sure if you threw enough money at it, you could tool up and build it, but you'd spend less just buying a new engine (which would not be cheap).
Oh well, you bought a Ferrari --- what did you expect?
