Injector question

[GDRBO]

I have an 87 w/ 2.9, 5 speed and 4.56 rear gears. I got a 4.0 from an Areostar, 93 I believe. Plan to use the ECU and harness from the Areostar. Heads and intake have been ported and a cam and headers to be ordered. While it is apart should I replace the injectors with something bigger? Do I need to change the ECU? If so with what? I do appreciate the help! Thanks.

I would say your factory injectors are more then likely big enough with what has been listed as being done to the motor.
