Hey!
I have a DOHC ZC in my 91 crx i have I/H/E and some other **** including nos

so i just got a B&M FPR and i need to know where to set thr psi on that bicth

 

bump

 

Should be set at 40-47psi with teh vacuum hose removed from the pressure regulator. Just stick your finger over the hose end while you are setting teh pressure.

I recommend you don't use your "nos" until you get on a dyno and get your AFR where it needs to be. Attaining the proper AFR is critical when dealing with FI/Nitrous.

 

its not a wet shot but i like your
comments - tell me some more will the place that i get it dinoed at set it how it should be or will they even tell me

Go around to your local import performance shops, find an expierenced tuner and offer him some cash to tune your car. Make sure you get a set of colder plugs before you go (NGK 7s should do..), set you timing to 14 degrees BTDC or so. Make some passes on the dyno, on and off the bottle, you'll probably want somewhere between 12.5-13.0:1 AFR. I'm not an expert on nitrous, so maybe you should ask in the FI board.

 

yeah i have got some zex spark plugs and have already set back the timming.
i did so reseach befor i got nos and but i just didnt know if it effects the FP.

thanks a lot for the tips

If your Fuel Pressure is too low, you're going to run too lean.. if its too high, you're going to run too rich. You need to find that happy medium... Thats where some dyno time comes into play.

You might want to look into getting some sort of fuel controller, too.

 

fuel controller?
i have a A/F gauge ant it runns in the middle for the most part

An Apex VAFC/SAFC, or Field VTEC Controller both control fuel
Hopefully its a wideband.. if not you're probably too lean.
