It had no acceleration at all...it was miss firing cuz it wasnt getting enough fuel...the moment I put the 255 fuel pump in....smooth throttle response ...100% change...u might have to change the thermostat switch or wiring the fans up to come on ( to a switch) I didn't have that problem that u r having...but I also swap out my old sensors to the f20b engine....how is your throttle response?

 

I have the pcb n51 ecu

 

I mean....there was no throttle response at all....it was miss firing...the engine was in need for more fuel...so I had to put in the 255 fuel pump...the moment i put that in....the engine ran perfect...but I never had the problem u have...u might have to wire up the fans to a switch or change the theremostat switch...I also have pcb n51 ecu

 

My throttle respond was great just no fans. but now I'm stuck with F23 ECU right now till my h22 intake plenum comes this week then I'll be running a chipped P28 w/ h22 basemap.

 

Gotcha....well in the mean time....u might wanna just run your fans to a switch...for now...once u switch to the new ecu...u might end up needing a 255 fuel pump...cuz I'm sure the h23 is gonna be in demand for more fuel

 

Do you have a name or part number for the 255 fuel pump you used. I am planning on doing the swap in my 2002 f23a1 coupe. Can you use the f23 motor mounts?

 

He probably just means an aftermarket walbro pump

 

Well yeah I have one in my integra still from when it used to be turbo'd now is just an ls. I was wondering if I could just take the pump from my integra and put it in my accord and put the stock accord pump in my integra didn't know how similar they would be from chassis to chassis

 

Any idea on the motor mounts?

 

Motors mounts will be good.

Not sure if a accord fuel pump would work in an integra, I would guess not though.
