Hi all

im in need of bit of help I have a s2000 turbo just wondering what the oil pressure should be when on full boost.

on start up I’m just under 6bar when hot And I boot it my oil pressure drops to 4bar or slightly under.

 

Fully warmed up engine should be at 5.5 to 6 bar at 3000rpm, Seeing pressure going lower than 4.5 while cruising over 3000rpm you stop the car right at the spot.

 

Oh what could the issue be ? I know this isn’t much help I’m running a oil relocation kit and a oil cooler

 

Oil relocation kits by there nature will drop the oil pressure. Oil coolers will also limit flow. The more rows you have the less pressure drop you will experience. Plus you also have a controlled leak through your turbo oil feed that further lowers the pressure.

 

So is my pressure to low ? If it is what is the process of elimination to find that issue ?

 

Knowing if you have a stock or built motor would help with answering that question. Bearing clearances matter. But as oil temp goes up, pressure goes down so you would need to compensate with a different weight oil.

I use to have mine setup going from a T fitting to the turbo and the other side had the pressure sensor.

I switched it to having a dedicated line from the stock oil pressure sensor port to my aem sensor and it made quite a difference. My motor is built pretty loose, but my oil squirters are blocked off. My oil pressure stays in the high 70s at 200*

So my car is a 2003 with a stock engine all I’ve done to the head is the facelift retainer kit, It’s running a Precision 5858 ball bearing turbo. Mocal relocation Kit and 15 row oil cooler all oil lines braided -an10 oil grade is 5w40
