FIC tech says: The IS125-0650 is a good injector. It is a Delphi core, low Imp. It might fit or need to be slightly milled down.


I'm still an injector newb. I know cc's and that the ID brand are the nicest & bestest but that's as much as I've learned. I know my RX7 550's can be improve upon as far as idling, atomization, response etc from a more modern design.

Will injectors from a 97 Eclipse which I am told were FIC 650's (IS125-0650) fit the Miata and are they a decent injector ?

I run these and they are the best bang for your buck out there IMO. Not as well matched as ID, however I'm not so sure I would have noticed a difference. I am extremely happy with my decision and I wouldn't hesitate to back the FIC's 100%.

Fit is perfect. No need for an extra spacer that could introduce another failure point. FIC guys are awesome to deal with and very knowledgable. I recommend ordering from them directly.
