After i installed my turbo the oil pressure will not go past 25psi at high rpms?
Is this caused by running the oil pressure and the turbo feed line off of the
same sorce?
If the car is cold it will read 50 psi then drop as the car warms up.

 

you should still seepressure above 25psi. even if you t it of the oil pressure sending unit location. It still should have pressure there.

would you have any idea what would cause this?

 

where is your pressure sensor? also, is your oil level good?

 

my sensor is at the end of my -3AN oil feed line just before it goes into the turbo.
I get about 30 psi at idle which goes down to about 15psi after it warms up.
then I get about 45-50psi max at revs.

my line tees off my block at the stock sender location.

you may want to check your pressure first at the block tap point and again at the turbo. I found out the hard way that I had no pressure at my turbo and blew my turbo up before I found out.

 

check your sender ground wire - it will give flaky readings if not getting a solid ground...

 

i think it's time pull the motor for a rebuild buddy....

 

the oil level is fine and the line tees off the block
thanx for the info guys
