If I replace my stock 94 cx fuel pump with a gsr fuel pump, will it make any difference in hp? The car has a jdm b16 swap. Some people told me that it doesn't and some say it does. I want to hear it from H-T pros. thanks.

Too many conflicting stories. I hear it's fine (CX pump) from some, and that a GSR/ITR/Si pump "feels" better top end wise from others.

I've not seen one bit of proof so far either way. Get a DOHC VTEC pump and Dyno it back to back with both. That's the only way you're gonna know for sure...

I wouldn't push a nearly 10 year old CX fuel pump to the max for very long. It's a good idea to switch to a B series pump with a B swap considering how easy it is to change in the EG.
I replaced my 92 VX pump with a 99 GSR pump and noticed an increase in the upper RPM's, whereas the VX pump obviously was close to cutting out. I can't prove it gained any HP by dyno charts or any of that but the good old butt dyno and A/F gauge (for what it's worth) wasn't lying.
