about what should the oil pressure be on a b18a1 at idle and in boost?
thanks chris

 

bump..also for a b16a2....

 

i thik in low 40 and 60 in boost

 

anythign above 60 should have a restrictor in boost correct.??

 

is it normal that when I start my engine the pressure jump to 80 psi ?

Maybe because my oil is cold...

 

damn.... this is scatuli but at idle im around 20 psi then in boost i think im at approx 60-80
so does anyone remember that nissian guy who made the restrictors?

 

yeah with my r pump i used to pull like 80 lbs on full load

but now on my y7 i get like 60 max and like 10-15 with no load

 

I am getting around 20psi once warmed up @ idle and around 70psi on boost.

99 Si.

 

ok i was just making sure, but would you still recomend a restrictor. the only thing im conserned about is that sometime the oil psi will get down to 15 at times.

 

Honda engines run aboit 10 psi oil pressure on idle
and they need to see around 50 psi around 3k rpms
all engines i have seen for honda follow this rule

and btw, oil pressure is high when engine is cold and oil is cold

once it gets a lil warmer and softer, it looses pressure..
plus, oil pumps are supposed to be opening their releif valves around 75-80 psi anyhow..........

 

when i first start my car when its cold itll stay at around 80psi. then when it warms up fully ill have about 25psi at idle(900rpm) and it will go up to about 83psi then the valve will open and it will fall back to about 78psi and stay there until vtec where it falls ~10psi instantaneously. it will also climb maybe 1 or 2psi per 1000rpm all the way to redline.

my oil pressure line is T'd off my ls/vtec line also

 

does anyone know the guy who made the oil restrictors? if so post it up
thanks

 

Oil restrictors - here ya go

 

YES... that is the one thank you!
