Emilio is now selling ID injectors, http://949racing.com/Injector-Dynamics-miata.aspx
, pic right from his site:
I didn't get mine from 949, got them from the local tuner, pic installed in my m-tuned rail:
If you look at the stock pic, the tip o-ring has a black plastic ring below it. The diameter of this ring won't allow the tip of the injector to insert into the hole in the head. I had to cut this ring off. I also took off the tip o-ring, and used a soft rubber tip grommet/o-ring.
Pic of the IDs lined up as installed, also shown without the adapter cap that they came with, next to the Marren 440s I was using in the 1.6, and the stock injectors from a '97 1.8:
The ID1000 measured 2.60", they were a bit longer than the Marrens and the stockers, but installed in the rubber grommets there was enough crush to work.
The Marrens measured 2.54", measured as per pic:
I'd like to see if Emilio will chip in some info on his ID injectors. Do they not come equipped with the black tip ring, do they require the same work mine did to install? Are they the same length that I measured (it says 60mm on his site=2.36", where is that measured)? Also says no wiring needed, mine just came with weather pack pins and rubbers that I need to crimp onto bear wire ends and assemble into the clips.
I'm not taking the rail out again, if you want any more measurements your going to have to blow me.
