Don't forget that you'll probably want to run it at WOT, with the turbo,
quite a lot richer than the NA engine. The extra fuel helps supress
detonation by keeping the temperatures down.
According to some notes I've got from somewhere, a NA engine needs about
4.6cc/min per Hp where as a turbo engine needs around 5.6cc/min per Hp....
or about 22% more fuel. Therefor, with a turbo, the Fiesta injectors will be
good for at least 98Hp.... but you can always raise the fuel pressure. Hope
this is of some help, Toby
