Can anyone tell me what fuel pressure I should be running, and what stock is?

JDM 1st gen B16A, with cold-air intake and exhaust.

 

Anybody? I don't even know what stock fuel pressure is for this engine

 

I'm starting to think this is one of those 'best kept secrets' things

 

FWIW, I run 38 to 42 psi depending on tune/timing/humidity...

I have a similar setup to you

 

If I remember correctly ( I don't have my Helms here at work) the stock pressure for a B16a2 is 40-47 psi. I know that you have a first gen., but since they are very similar, I would chance it that 40-47 is a good place to start.

Someone please correct me if this data is inaccurate.

 

Crikey, 40+?

I had it at 40 psi for a while and the plugs were very dark (they actually had unburnt gas on them), so now I've put it to 32 and it seems to be running better.

I wonder if my B&M gauge is off?
