The 2.0 puts out double the power, a lot more component stress
If you put a turbo on a 70 Maverick it would blow a head gasket in a week or blow a rod out the side of the block

Batteries were dead in a week on lot vehicles

As they get more data the date ranges may be expanded & a TSB may be issued
