I am hoping someone here can help me find o-rings for my Ev14 900cc injectors. The top o-rings seems to loose in my m-tuned fuel rail. As for the nozzle o ring I have nothing. Do I need stock o-rings or do I need special o-rings for the ev14's? I don't have the stock injectors. Also these seem a little longer and it seems I may need to turn the spacers down? What do you guys recommend?

Thanks

 

You need bottom cushions - Denso Bottom Cushions (4x) ? Flow Force Injectors
And I have some bigger o-rings that should work for you. If you want I can send you 3 different sized sets of o-rings and the bottom cushions for $20 shipped and you can figure out what works the best.

 

Also, those connectors might not fit. They won't fit a stock fuel rail.

 

Are you referring to the plug won't fit the stock harness? I'm going with a complete standalone so a new harness is will be made. This is all getting crammed in a festiva. I'll pm you when I get home about o rings.

Thanks!

 

Those aren't going to drop in without modification. It sucks, but it's why you should buy from Miata vendors.

 

Those connectors probably won't physically fit. As in, they are stiff and stick out of the side of the injector. You might get lucky with your fuel rail, but there just isn't that much space in there once the intake manifold and fuel rail get bolted on, and you connect up to a harness. If it doesn't fit, I've got connectors that will fit as well: USCAR/EV6/EV14 (injector side) to Denso (harness side) Plug and Play Connector ? Flow Force Injectors or Universal USCAR/EV6/EV14 Pigtail Connector ? Flow Force Injectors

Also, for a stock fuel rail these make them fit a lot better: Miata fuel rail spacer ? Flow Force Injectors
