OK I need to order an inline fuel pump for my soon to be B16 Rex, what fuel pressure do you sujest? im just going to use the SI pickup on my Dx tank and go with an external fuel pump. Also how many GPH do you sujest to keep the motor fed.
Thanks in advance, Matt

i use the msd external fuel pump...works great..i also use the xs fuel pressure regulator..but i would recomend the B&M regulator..works good enough..also set it to about 35 psi for stock sorta setup

the gs-r and b16 have different fuel pressure. the b16 got 38psi and the gs-r has 45. its not good to have too much pressure because it works the pump making the fuel hotter lowering hp. but im talking about a lot of fuel pressure the stock numbers should be fine. checkout the walbro pumps also.

The workshop manuals says ~2.8 to ~3.2 bar. (EDM workshop manuals, so you have to convert it to PSI yourself)
EDM AS CRX - B16A2 engine - Y2 gearbox - P30 ecu - more coming

That would be 40.61-46.41 PSI for the mathematically challenged.

This is were an air/fuel ratio meter would be very handy. And absolutely, you MUST have an adjustable fuel pressure regulator.
You can guess at the correct fuel pressure and run the risk of being too rich (power loss and foul your catalytic converter) or too lean (burn holes in your pistons). Or use a A/F meter to get it right.
