Hey everyone, I have a 91 crx si with a d16y8, p28, obd-0 injectors running through the injector resistor box, and I/H/C/E. I just got the car running correctly and I bought a b&m regulator and gauge. My question is what fuel pressure should I be running. I set it to 40psi because I figured that it would be a safe bet, but I dont really know for sure. So........ what should I be running?? Thanks

p28 ECU - that's for the D16Z6 right? I think you should be using the injectors that were made for that ECU - Z6 injectors... But, I really don't know.

Anyway - my Y8 FPR ranges from 41 Psi to 47 Psi.

I don't know how adjustables work... I mean I'm not sure if you should set it to the base Psi (41) or somewhere in the middle of the range (maybe 44?) or at the highest Psi (47)...

 

Cool thanks, as for the injectors, the car had obd2 injectors running through the resistor box, but the car really ran like ****. So I changed the injector plugs and gave the obd-0 injectors a shot and the car is running really well. I know it really doesent make much sense to me but, its running good so I am going to let it be for the meanwhile.

 

What amount of pressure are you going to set it to?

Just wondering 'cuz I'll be buying an adjustable FPR in a couple weeks or so...

 

Well I am going to run it at 40psi for a while, but then I am going to expirment with raising it to mabye 45 or so. I am going to a test and tune night pretty soon, and I am a pretty consistent driver, so I want to see if messing with the fuel and the timing will do anything for me. If not then ohhh well but it is at least worth a shot. I heard somewhere that a car runs its fastest when it is running as lean as possible, but then you risk damage. I dont really know if that is true or not but I guess I will find out .
