yes they plug right in. Tuning them is another story.
(USD) '99-00 injectors are actually only rated at 238cc, but run at 60psi as opposed to 50psi on all other miatas. The ECU would probably have no trouble idling 94-98 and 01-05 injectors, which are rated at 265cc. An increase of 11%. Capable of 215BHP at 100psi of fuel.
I'm sure it could idle the supra injectors, but you may see a rich idle. I dunno how a MAF miata would go about leaning out the idle without an ECU, unless the ECU can compensate for a 22% larger injector.
Early miatas can mess with the AFM and adjust flapper tension and idle mixture.
