hi everyone, just bought my first 300zx on friday, its a 93 twin turbo fairlady, runs really nice although iv noticed the oil pressure seems very high, its measured in kg/cm and it steadily goes up to between 9 and 10 the gauge ends at 11 so im quite worried about it, iv checked the oil level which is fine, just been serviced, its had a ecu remap and bigger injectors put in, but now im thinking about not driving it incase i do any damage, any ideas what it could be? everything else seems fine and it got me back over 200 miles no problem. thanks very much.
