Does anyone have H22A injectors in there all motor B-Series? What PSI are you guys running at and with what setting? I sold my header today and I replaced it with a stock B-series header. It ran kinda rich so I lowered my fuel pressure to about 30PSI. Its still running rich and its throwing a code 43 which is fuel system malfunction. I figure maybe cause its running too rich. Im running an lsvtec with CTR pistons and GSR cams... FPR, no cat, 2.5 exhaust... don't you think 30PSI is kinda low? I know prelude injectors are 345cc's, but im not sure PSI it takes for it to be 345cc. I was just wondering what you guys think...

 

So are you using the OBD 1 peak and hold injectors? Just curious.

 

B=240cc
H=330cc

I think you need the injector RESISTOR box if using the obd1 injectors. Not too sure about the OBDII ones

 

i'm running the same setup and my fuel pressure is about 30psi on stock injectors, and it runs rich as hell! I REALLY DONT GET MUCH INFO ON LS/VTEC ON THIS FORUM, BUT MAYBE YOUR HAVIN BETTER LUCK!!! I'LL TRY IN KEEP UP WITH THIS FORUM

any one know</TD></TR></TABLE>

92-96 Prelude "peak & hold" injectors (required fuel injector resistor box) are 330cc. The 97+ Prelude "saturated" injectors do not require a FI resistor box, and are 290cc. Both require different plugs on the harness.

you're running 30psi with stock b-series injectors? what fuel pump are you running? you're using the stock ls headgasket with ctr pistons? when i had b-series injectors i had to run over 50PSI or i'd detonate.
