Please stop shopping for parts on eBay. No, those injectors are not any good. They look like modified OEM injectors, which were old and crappy to start with, and then someone hit them with a hammer which makes them flow more but makes them virtually uncontrollable at low duty cycles. IOW, they are going to idle like absolute shit, even worse than normal EV1s of that size, which already idle like ass.

If you're on a budget, go find some Rx7 440/550s or better yet some Rx8 420s.

I have a set of RX7 550's that I'll sell you for $75 shipped so you don't look at stuff like this.

Theyre probably just some delphi disk injectors. Maybe comparabele to RC or Precision.

Having a set of OEM injectors cleaned and low tested could cost you 80 bucks, so it may not be a bad idea assuming the ebay injectors are actually cleaned and flow tested, which they may not be.
