i can use diferents size of injectors in my engine???

[GTdan]

from what im aware you need to run 4 of the same injectors - so you need to find another rx7 with same injectors and get them and have a set of 4.
You cant run 2x550s and 2x460s - unless youve got some stand alone management software and even then, i cant imagine it being easy to set up.

it'll run like shit with mis-matched injectors.

the problem is that my ecu isn't programmable, or how i can tune the car with out a pyggy-back or stand alone ecu

get SAFC to make fuel correction in ur ECU

Can be done by tunning two banks of injectors to different timing by a standalone but not recomended. Better use 4 identical each other!

Use 4 same size injectors (330 or 440). then your gonna have to tune with piggy-back or standalone management.
