would a braided 4an line be enough restriction not to need a oil restrictor? or will it still be too much pressure?
its the opposite, the smaller line would be better for oil restriction, -3AN would be ideal but ive heard people still using restrictors even at that.
Your gonna need to get a oil pressure guage and see what it reads if your not sure.
I have -4AN line feeding my turbo and it still needs a restrictor.
