Ok so I was running a stock block single turbo etc and oil pressure always was around 60-80psi untill I took it out due to blown coolant seal. I acquired a extend port block and finally got it all bolted back in and cranked it over this afternoon, oil pressure sat at 60psi at idle then jumped and sat at 100psi, where it still sitting still.
What would cause the jump? Would oil overfilled cause it?

they probably modified the rear oil press. regulator to increase oil pressure.
