i just put a new motor in my 86 rx7 and the stock gauge never really worked but i put new aftermarket gauges in and i was just wondering what is the range of the oil pressure that i should be getting hot, cold, at high rpm's thanks. Is it normal for a newly rebuilt motor to idle a little rough until it breaks in?

 

30 psi at idle, 60 and over at speed.

 

is 80 high? when at 3k rpm's?

 

The stock oil pressure regulator can go up 73lbs. Your motor may have a custom regulator. But it won't hurt anything to have 80lbs at speed.

I have a new motor in my turbo and there is no rough idle at all. You prob have a vac leak somewhere.

 

do you possibly know where the car was flooding out but my ecu was bad i popped that in and the car runs great but at a stop the idle is a little rough thanks

 

i have an atkins street-ported na with an autometer gauge and I range from 28 to almost 100lbs. Also, idle thing is not that strange, be sure to warm up the car and check tps, timing, then idle setting. if still rough check for vac leak. How rough we talkin?

 

not very bad, when i come to stop in gear my tach seems to go down below 500k and the car feels like it's going to die but it never does i just got it back today i haven't even driven it 2 hours yet? The rebuild is a rx7world stage 2 mild street port brand new motor 0 miles? Thanks Chuck
