2 questions, at least one is sensible...
The (CF1,2,3) TS engine crank case is cast iron. Heavy and heats up slowly, causing poor mileage on short trips. It was made this way to make it cheap to manufacture, as I understand it. Has anyone ever had one cast out of ally?? Could a company make a profit by copying the design and having a batch made to sell to enthusiasts?
Secondly, the 2.0 crank case has a blob of iron sticking out on the belts end where the balance belt idler sits. Has anyone taken an angle grinder to this and removed it before??
Engine block is extremely complex cast and manufacturing design, even car manufacturer often stick to the same design for decades and re-design only the intake/timing/exhaust/fueling system.
And you can not just make an alu copy of cast iron part 1:1. Aluminum is not as strong as cast iron, so it needs to be much thicker in critical places means completely redesigning the engine,all its walls and passages. Moreover you can not put pistons directly into alu block as they would wear the walls on the first day. You either need to use high tech nicasil or alusil technology on the walls or insert cast iron liners, wet or dry, in both case it means redesigning the complete cooling system and water passages. Basically you would need to change the complete engine concept and you would not be able to use most of the other parts from the original engine...
If you go out and buy a new Ferrari, you will still save a fortune compared to custom engine design...
