Just checking my oil pressure and what you guys think. This is on a stock block, head GSR with Holset HX35 and no restrictor. as read through a mechanical Auto-Meter oil pressure gauge. I also just installed a rebuilt OBD0 B16 oil pump today.

Cold startup=60psi
Warm Idle =20
At about 3k =60
WOT, 6k+ =75

 

is this oil pressure at the turbo or from sending unit?

 

this it "T"d off the back of the block

 

i think its fine.

my car gets around 70 at cold start, 22 or so at warm idle, and 75-90psi up to 8500 rpms

 

ya it seems right on the borderline of being too low, i was thinking of shimming the oil pump but dont know the specifics, or if it would even be a good idea.

borderline of being low? where you getting that from?......anything above 60psi over 3000rpm is perfectly normal....and anything above 10-15psi at idle HOT is normal.....what grade of oil are you using?

i noticed a diffrence from a simple oil filter change. i went from a fram "tough guard" oil filter to a regular fram filter and saw a 10psi oil pressure increase with the regular fram filter........with the same grade of oil too....

X2 anything above 10-15PSI at hot idle is ok and anything above 70psi at WOT is ideal.

i was searching and in the past all the posts i found were guys sayin 70-90 at WOT is perfect, below that is too low....according to archived posts. But VTEC is engaging just fine and alls well, so i guess ill leave it alon for time being.

Oh and im using Castrol GTX 5w30.

 

You need to get some thicker oil in there.
