[s-cars] Alternatives to RS2 Injectors

Sometime back I cut and pasted all the injector data I found into a text
file. I was interested in "alternatives to RS2 injectors" at the time and
learned enough to move forward. Most of it came from this list. Read
carefully and with caution as I wouldn't want anybody buying the wrong
injectors from my attempt to help.

 I've uploaded it to:
