My quest of running Ford GT500 EV14s

Does that piece need to come off? I feel like I've seen pictures of ev14s set up for a miata that still had them. I got the seal on fine with it there. Don't have a manifold handy to test fit on,so I suppose there's a chance it would bottom out and not allow it to seat properly.

I left the plastic piece on there and used the lower cushion as you show it in the pictures. It was a real tight fit, but a little wd40 on the cushion allowed it so slip into the injector bungs and seal really well. I have over 5000 miles on the setup so far and no issues. I like that you end up with a tight seal between the injectors and manifdold. The RX7 injectors with new lower cushions fit really loose and I always wondered if I was leaking out any boost when I ran them, I don't worry about that any more.
I tried to find a fat oring that would make the ev14 fit the miata manifold but didn't have any luck.
I looked at all the places I tried to get my injectors from in the spring when I paid $25 a pop. All the places charge at least $50 a piece now. Glad I got mine when I did. Rockauto has the Standard Motor Products injectrs for the 2013 GT500 for $30 a piece which is crazy since the real Motor craft parts were $22 before.

Watching this space closely, as I'm not sure if my yellow tops are going to be my power limiting feature. Making this change seems to be relatively painless from a wallet point of view.

Well, my injectors are hopefully finished (though I haven't cut the plastic piece off yet. One yes, one no, so I figure I'll test fit and cut if needed). However, could someone confirm the overall length of the injector? The extensions I ordered were not the extensions I received, but the OD looks correct.
