What is the stock fuel pressure for an h22?

 

Anyone have an idea? I have an adjustable fuel pressure regulator and I remember it being at 45 psi, now it is down to 40...

 

50ish

 

ppl on po.com said like 32ish

 

hmm thats a big difference... is it 50 or 32?

 

I think its supposed to be somewhere around 40. I think the 97+ preludes have 50 ish. They have 290cc injectors vs 340cc

 

37-42 psi at idle......thats straight outa the honda service manual

 

ok, the motor is an 01 2.2 Thanks guys

 

the 97-01 is 50-54 i think off the top of my head.

thats for an h22a1

as fasr as i know the 97 and up engiens are h22a4's.

according the the 1997-1998 Honda Prelude Service Manual on page 2-5 in Section 11 Fuel and Emissions:
Pressure with regulator vacuum hose disconnected: 47-54 psi

 

Yep. 5th gens have higher fuel pressure - because like i said, different fuel injectors 290 vs 340 - they have to perform the same correct? What other way to make that happen?.......up the fuel pressure

 

i have mine set a 50 at idle and i'm runnin a test pipe and internals

 

My lude has the 11:1 CR and the headwork ect and at 47 psi (idle) I started throwing a code 43 (rich), that was on a stock ecu and fuel maps BTW

 

ok, so mine is low... now I have to figure out how my regulator works... hehe thanks for all the help, this site is awesome!

 

what injectors are you running?
