I am getting high oil temps on my new setup; they got north of 240* before I realized and shut it down. this was when I was just driving around town and I was not even in boost, below 4,500 rpm's. I have a built h23. I am running a -4 oil feed with out a restrictor on a journal bearing turbo. Could this be causing my high oil temps. I am also going to wrap my down pipe and install a turbo blanket. Also my water temps are 185*. What can I do to fix this? maybe a .065" oil restrictor.

Any intelligent response would be appreciated.

when im on the hwy, its normal for me to see 230 degrees or so cruising at 70-75. @ 80+mph itll go up towards 250 degrees.

I dont see an issue with it really. if you are worried perhaps you should get an oil cooler.

I think that I might have to. My theory was that by using a .065" oil restrictor the turbo would be flowing 1/8th the amount of oil through, in turn limiting the amount of oil being superheated by the turbo.

where are you reading the oil temp from?

My oil temps rarely go north of 220 unless Im really beating on the car. ~200 is cruising, measured at the pan.

I am reading them from the oil sandwich plate on the back of the motor. I installed an .065" oil restrictor today and a turbo blanket. Hopefully the test drive goes well tonight.
