My car has been swaped to ITR on GSR. I"m running into problem where I'm using jdm p73 ecu w/ gsr injector & fuel pressure.

I have already changed o2 sensor and sparkplugs. i need to either find my self usdm ecu which will match up with injector or find myself jdm injector & fuel pressure.

I have done many many research on size of the jdm injector and came out with nothing. i have been told so many storys. is it 270cc or 290cc ??? also if it's 290 where can i find it???? also is jdm fuel pressure different than usdm????

 

pretty sure all itr injectors usdm and jdm are 240s, get 97+ prelude injectors their 290 for sure

Let me see if I got this right...you put a JDM B18C into your GS-R, right? You're using the JDM ecu, with your stock gs-r injetors and FPR, right?

I'm not sure what your problem is...lol All Integra Injectors are 240cc. I'm not certain about the fuel pressure regulators being different. I know that the ITR fuel pressure is pretty high, around 55psi.

So why is it that you don't have the FPR that came with the JDM engine?

Changing the ECU probably won't do you any good. And most DOHC VTEC engines run pig rich anyways. How do you KNOW that you are running under lean conditions? What did your plugs look like after a few hundred or thousand miles?

 

will my friend thought they are same, so he didn't bother to change injector & fpr. very 1000 mile, i pull the sparkplug, they are white it also goes with o2 sensor.

 

Do you have adjustable fpr and gage?
If you don't get one asap.
You should be running at least 50 psi.

 

stock gsr fpr is running @ 55

 

i can't see a stock fpr putting out 55 psi.
Does your gage say 55?

yeah, all stock fpr that i have seen with a gauge with the hose off have measured about 44psi
