Your best bet would be some DSM injectors, but as previously mentioned 6.5 pounds of boost from a T3 isn't much air.
Sorry buddy Turbo 2 RX7 injectors are 550cc injectors, and they can be used with honda's. They are sized about the same way as DSM injectors so they will swap in. Trouble with those injectors is you have to be real carefeul about what year car your get them from, because Mazda swapped from low imp. to high imp around 87.5(I think). I searched FOREVER for 84-85 gsl-se injectors(680cc and low imp), but they are rare as shit and usually need a rebuild. Depening on the impedence of the injector they will either drop right in(low imp) or require a removal of the factory resistor box(high imp). But here's a quick list of some commonly found injectos that may help you.
89-94 DSM 5-speed ~ 450cc, Blue tops, low imp
89-94 DSM Auto ~ 390cc, low imp
95+ DSM injectors ~ 450cc black tops, high imp.
84-85 RX7 GSL-SE 680cc, low impedence but only 2 per engine tho.
86-92 RX7 non-turbo 460cc(4 count), low or high impedence depenging on year.
86~92 RX7 Turbo 2 550cc(4 count), low or high imp.
Don't argue with me about the sizing on the non-turbo model's injectors. The only thing that stops Rotory engines from making power is lack of fual and they suck fuel down like no other. The injectors are also "staged", where 2 fire at low rpms and 4 at higher rpms.
Also why do you just need 2 injectors?
