what should the oil pressure be for a 99si with bolt-ons, also, does anyone know what "T" to ask for when i go to the store to get it for the autometer gauge. im going to t off the factory oil pressure sending unit.

 

anyone?

 

IIRC, my old car was around 20-25 at idle 25-50 up to about 3000-3500rpm and 75-80 from there to redline. Very rapid secession off idle. Oil pressure builds up quickly.

I didn't need anything else other then what came with it. I had an electric one. Yours mechanical?

 

yes this is going to be an mechanical gauge.
