ok i just put a b20 in my formerly b18b equiped teg

im getting 35 psi of FP now. ive heard that b20 should be at 45psi at idle.. so what have you b20 guys done for fuel setups? should i just get the b&m?

 

I have a b&M pressure at 48 psi w/o vacumn. Car runs rich, needs SAFC

 

hmmm my car seems to be runnin hot so i was thinkin it was a tad on the lean side... well ill get the damn FPR anyway but i wont be able to go to a dyno till the 19th of oct... just hopin i could find an answer before that

 

I have a JDM H22 FPR on my B20B and its at 40 psi during idle.... sounds like i need a B+M Regulator aswell.

JDM B20B
15.1 @ 89mph
On HX's with the stock (bald) Firestone tires.

 

OK guys - do the math...

yeah basically to use stock 240cc injectors to make the estimated power of 150hp (stock crank power) you need 45 psi on fuel pressure....

i could also drop in some 270cc's with 35psi id be right there....

 

Back from the WAY dead...sorry.

I installed the fuel pressure gauge to check what pressure I'm at before I installed the adjustable fpr and I believe my fuel pressure is way low.
26 psi? This is while the car was running. Shouldn't I be around 45 psi?
I'm using stock 240cc injectors with what I believe is an LS fuel rail on a B20Z2 motor in my '98 Civic Ex running a P75 ecu.

Fuel pressure reads 32psi with the vacuum hose disconnected at idle. I'm gonna throw the fpr on tonight and get it up to 45psi.

im bringing this back from the dead again for an update... getting a code 45 and im assuming its for a lean condition... wondering if the fpr took care of your issues and what you set it to w and wo the hose on it
