Is it right that I want to swap a Busso v6 into a Alfa 4C or would that be sacrilege? What are your opinions?

If you do this you will be the fuc*ing boss

Soon V6 bi Turbo version of this car,6C will come.The engine will be made by Ferrari and will be used in the new coming Ferrari ( will may be new Dino ) as well.
About swap,yes it would ruin the car.A 4 cylinders Vtec would work well because of weight.

Not a sacrilege. That’s genius!
