its a type r oil pump new oem i never repair cranks i always just buy a standard one. so i can use standard bearings that way the machine work is cheaper when they balance everything . my oil pressure is about 24 or 26 at idol around 50 drinving the speed limit and about 75 when i get on it maybe 80 but i have never looked at the gauge at 9000
