Default Injector upgrade necesary?

Would you have to upgrade injectors with a JRSC at 6 psi? what about at 9psi? What injectors would you recommend? It for a OBD0 b18c in a crx.

at 6 psi it is not needed, may wanna upgrade the pump, but at 9 i would seriously consider some 440's.

I believe the JRSC kits come with a Walbro fuel pump. At least the kit I installed did.

I guess it would depend on your fuel management. If your going Hondata, sure get bigger injectors. If your going with a VAFC then your injector choices are limited. If your just going to run a FMU then bigger injectors will prob run like **** with the stock ECU.
