3tgteu injectors would be ideal for 200hp and fit the same as original 18rg. If you are chasing the 250hp as norbie states you will need at least 350+ cc injectors, mazda famila injectors may be a good option. If using them with the standard comput just make sure the impendnce is matched. The 18rgeu uses ballast resistor and low impednce injectors. The 3tgteu injectors are high impedence therfore the balast resistors should be removed.
When you buy the injectors you should measure the restance to know what you are getting anyway. Low impednce ~2ohms high impedence ~12 ohms.
How big is two big cc wise will depend on your computer ability if using the standard computer you will want to use the smallest you can get away with for the horsepower you are aiming for. Two big will cause you idle problems. I would say 500cc would be the absoule limit for the standard computer and that would take some serious tuning and drivability/idle would be average.
