Hello there. i am just curious...

how much is the recomended oil pressure on a turbo b16a2 engine?

mine oil presure gauge (glowshift) reads at
-800 rpm 18 psi
-900 rpm 22+ psi
-3000 rpm 60 psi
-4000 rpm until redline 80 psi


i see sometimes for 1-2 seconds at idle drops to 15 psi at 800 rpm after a lot of driving.

my oil pump is b16a2 OEM with spring from itr oil pump with 1.5mm washer too.

is this normal? my idle presure is low or is ok?

 

I have an h22 not a b series with an Autometer electrical gauge and that's basically what I'm getting..Your oil pressure shouldn't be any different with a boosted setup compared to stock.

 

So this is normal right? I mean the 15-18 psi at idle..

have to worry about anything else?
80psi presure is ok for 9300 rpm? Is safe?

 

That's a little low at idle compared to my car. I sit at 20-25 on mine. Every car is different though. My idle is also higher than 800 though..80psi is fine in the upper RPM range when I go past 4-5k its 75-80psi.

DISCLAIMER: I am not saying 9300 RPM is safe. But 80psi of oil pressure is fine for upper RPM IMO.

 

Service manual says 10psi, after engine is warm at idle.

 

Just to clarify for the OP that it is 10psi "Minimum" as in the Helms. Should be 50psi minimum above 3K Rpm. So if its higher that is fine.

 

thank you a lot guys for your info.

 

That's correct.
