The next problem is you have is that you have the GTie. All the FIRE engine models had the same front springs and these are the ones often sold. As the GTie engine weighed more, it has stronger springs. Where my knowledge is lacking is that the turbo had different springs as it was heavier up front also, but I don't know to what degree.
ePer does not go back this far to check either! As it is similar weight to a GTie engine, I would say go for these turbo springs as opposed to FIRE ones. You just don't seem to get aftermarket standard springs for the GTie advertised. Once you talk about lowering springs, they seem to just say "they fit anything". Perhaps true, but they must be a compromise for the heavier engine cars.
The ones I would buy are
here. Fit them both. Good luck.
