The oil pump, and engine bearings are all within specification. It has an external oil cooler.How do you increase the oil pressure from 3 kg/sq. cm on a newly-rebuilt '87 Supra with turbo and oil cooler?
3kg /sq cm is about 42.6 pounds sq inch that is normal for idle. to up the pressure even more the pump in the oil pan needs to be replaced or rebuilt the relief valve is on the pump also. you can change the spring pressure also they have kits in the rebuild kit for the pump.
3kgs is what my rx-7 ran at and it lasted for three years untill my girlfriend overheated the engine and you had to push it to start.How do you increase the oil pressure from 3 kg/sq. cm on a newly-rebuilt '87 Supra with turbo and oil cooler?
external oil cooler can cause some drop but not a lot
speaking from experience with a small block chevy motor, you'll have to drop the oil pan and adjust a screw on the oil pump that controls pressure
