been looking into getting an oil pressure gague before i go to boost my 96 ls integra, and always been wondering what the range should be 0-100 or anything higher than that..

 

0-100 is fine.

 

I have a 2001 Stock B20Z with fuelrail intake header and exhaust and my oil pressure is around 20 psi at idle and 75 to 80 above 3000 rpm, can anybody tell me if thats normal cause it seems kind of high to me.
