Both FIC and ID have people posting from their companies actively on various enthusiast forums.
Either way, my statement was meant to denote the difference in starting injector and boring (Aka, the big difference between the typical eBay process vs. what more reputable shops use), rather than the post-boring process.

If your going with nice injectors, I highly recommend these guys:
http://www.injectordynamics.com/
Paul Yaw is an awesome dude and I have seen the injectors used in some high HP builds and work flawless. Plus you get a full profile of the injector, which is rare.
Not to sound like a salesman haha.

Used Denso 540cc $150: https://www.miataturbo.net/miata-parts-sale-trade-5/denso-540cc-pnp-injectors-64975/
NEW DeatschWerks 600cc $285: https://www.miataturbo.net/miata-parts-sale-trade-5/new-old-parts-act-zm2-xtss-clutch-walbro-255lph-hp-dw-600cc-injectors-more-65057/ New in box, never installed
Used RX8 425cc $75: https://www.miataturbo.net/miata-parts-sale-trade-5/rx8-yellow-injectors-denso-195500-4450-a-65301/ If I didn't have injectors pending, I'd buy these.
The 425cc should be good for a shade over 200hp @ 3bar. Remember your NB fuel system runs around 4bar, so that meas 490cc in an NB, good to about 250hp. Just to complicate things even further, the NB does not use a vacuum referenced fuel pressure regulator, so every +psi of boost in the manifold is -psi on the fuel system. The 4bar/58psi rail pressure @ 12psi manifold is actually 46psi, so right around 437cc and 220hp. RC Engineering has a great free calculator HERE.
Take a look at DeatschWerks in the MT Vendor area of the classifieds. I'd HIGHLY recommend taking advantage of their cleaning and flow testing service upgrade when buying a set of used injectors.
All the injectors listed above should work for your application and all are available right now in the MT classifieds. These should all be Plug & Play for the Miata head/fuel rail/wiring but not the stock ECU. Go make some offers man!

Thanks dude! I'm picking up the rx8 425cc's just glad I got pointed in the right direction. Im running megasquirt 2 diypnp from braineack. I love the autotune feature. My t3 is pushing 7psi right now and I know the stock injectors can't handle much more. Im planning to set it at 10 psi and go from there. I need to redo my.thread on the setup. So much has changed and I did it all on a budget
