1. How would you modify the existing ignition curve required for a turbo?
2. How would you deal with the extra heat?
3. What mods would you do to the clutch?
1.) Standalone EFI with 3D spark control.
2.) That's part of the reason for this thread. Besides the obvious larger radiator, I don't know what other cooling system improvements can be made. Water pump housing? Impeller?
3.) If needed, stronger springs, a billet pressure plate, and if absolutely necessary, a billet basket could be done.
